PsP - Psionic Power

Striker: don’t bother. Although you can become a bad blaster as a Tiefling Firestarter or a bad Elementalist by optimizing ranged basic powers like Mind Thrust, the psionic power source is not well enough supported to really get those plans off the ground. Especially at higher levels this becomes problematic, since the damage of Psion powers doesn't scale with tier for some reason.

Defender: yes. With your cloth armor and simple weapon proficiency, you should definitely try holding off the enemy in one-on-one combat. Some Psion powers like Memory Hole and Kinetic Buffer are interesting for defenders though, but those are best left to hybrid builds.

Leader: you can get great leader powers if you want (Mind Thrust, Forced Opportunity), and your repositioning capabilities are pretty good. By investing in things like skill powers and a leader multiclass (Shaman FTW), you can even make a passable secondary healer. You can go this route if you have another good controller in your party and lack a defense-debuffing, attack-granting leader.

Telepathy Focus: Distract generates automatic combat advantage as a minor action once per encounter, and Send Thoughts lets you send a limited telepathic message once per encounter. Both powers are pretty meh. They can be boosted with feats, but it’s not really worth the trouble.

Telekinesis Focus: this is more interesting. Forceful Push gives you free action forced movement once per encounter, and Far Hand is an encounter power Mage Hand. Both powers can be significantly improved by taking their respective feats. Forceful Push then also slows, which is great for a free action range 10 forced movement power. Far Hand can then be sustained as a free action, which is useful if you have your hands full for some reason but still want easy access to a certain item.

Shaper Focus: now we're talking. Minor Creation lets you conjure up a nonmagical item each encounter, which is awesome for roleplaying purposes ("here’s the note from your captain that says you should let us in"), although officially it can only create a weapon or an item listed under Adventuring Gear.
The standout power though is Shaped Consciousness, which grants you access to the Dream Form from the Dreamwalker paragon path 10 levels earlier. Sure, it’s a minor action encounter power instead of a free at-will, but it blocks enemy movement and lets you look and cast in melee while you’re hiding behind a pillar or door. It even absorbs one hit per encounter, and a paragon feat boosts your defenses a little while you’re near it. That is an awful lot of utility for a single class feature.

Strength: your designated dumpstat. There’s simply nothing for you here. Don’t think about going into melee, don’t bother getting Hide armor. If you absolutely, positively have to have a melee basic attack, multiclass Swordmage and get Intelligent Blademaster.
Recommended starting score: 8, pre-racial bonuses.

Constitution: it never hurts to have a good Constitution, especially for some semblance of Fortitude since Strength is your dumpstat. Also important for your summons' HP if you take those powers, although they're not very good. Other than that, don’t bother putting in points that could otherwise have gone into your Wisdom or Charisma.
Recommended starting score: 10-13, pre-racial bonuses.

Dexterity: although your Reflex is taken care of by your Intelligence, and you don’t need Dexterity for any feats or class skills, it’s still nice to have some Dexterity when you roll initiative. Especially since you’re a controller, because the outcome of your turns will pretty much dictate the flow of combat. Tieflings and Wis-Psions can tie their initiative to their Charisma and Wisdom, respectively, so for them it's another dump stat. Gnome, Wood Elf and Shade Psions who specialize in Stealth should make this their tertiary stat instead of Wisdom or Constitution.
Recommended starting score: 8 for Tieflings and Wis-Psions, 12-14 for Gnomes, Wood Elves and Shades, 10-12 for everyone else, pre-racial bonuses.

Intelligence: although it’s tempting to crank this one up all the way to 18, doing so limits your power selection to powers that don’t have important Wisdom or Charisma riders. And I’ll tell you right now: there are plenty of those that you don’t want to miss out on. So unless you value accuracy over everything else, just put this at 16. Conveniently, this also gives you a great Arcana, which is nice for your rituals and possibly Sage of Ages.
Recommended starting score: 16-18, pre-racial bonuses.

Wisdom: powers with a Wisdom rider are linked to telekinetically-flavored powers. The more interesting of those powers don’t show up until late heroic and paragon, so if your game doesn’t go there, you can safely dump this. Be aware though that three of your class skills key off it, among them one of the most important skills in the game, and that you need 13 Wis for a Druid multiclass. See the multiclass section for why you'd want to do that. Also remember that you need 15 Wisdom for Psion Implement Expertise at epic.
Recommended starting score: 12-16, pre-racial bonuses.

Charisma: the Charisma powers are flavorwise linked to telepathy. Unlike the Wisdom powers, the Charisma powers are some of the best in the Psion’s arsenal, and you have access to them right away. Two powers at level 1 that massively debuff attacks and defenses, and the Psion’s equivalent of Shield at level 2 (although why this doesn't have a Wisdom, thus telekinetic rider I can only guess). Simply put, if you want to use the best powers the Psion has to offer, boost this and be happy with it. Charisma is also tied to three of your class skills, which are all social skills. Lastly, be aware that you need 15 Charisma for Psion Implement Expertise at epic.
Recommended starting score: 12-16, pre-racial bonuses.

Arcana (Int): this will automatically be high due to the fact that it keys off your main stat. It’s also does a lot of work in skill challenges, lets you cast rituals and grants you access to skill powers like Warp in the Weave and Insightful Warning. Also good for the Sage of Ages epic destiny. Simply put, you want to be trained in this.

Perception (Wis): avoiding surprises and noticing clues are two very, very important things to ensure the continued lifespan of an adventurer. The utility powers are nothing to write home about though. Even more important for Wood Elves to boost their initiative through the roof.

Insight (Wis): good for getting to the bottom of a social situation, but the real value lies in the skill powers. Insightful Riposte at 16 is considered to be one of the best utility powers for a reason.

Dungeoneering (Wis): train this if you're planning on taking Stay Back as your level 2 utility power. If not, then it's only useful if you’re going to be underground a lot or will face off against aberrant hordes.

Diplomacy (Cha): just generally useful for nonhostile situations. Lets you be the party’s face if you lack a Bard. Indomitable Ally is a good but risky power for keeping your leader on his feet.

Bluff (Cha): very useful for when you need to lie your way out of a difficult spot. Also has hilarious uses with Send Thoughts if you want to be a ventriloquist or convince an enemy he’s hearing voices. Not much for combat though.

Intimidate (Cha): Everybody Move gives you an out if you somehow got yourself stuck in melee, and Snap Out Of It lets you minor in leader. Beyond that, you need to do some of your best roleplaying when a scrawny guy or girl like you tries to threaten that nasty hobgoblin. Like Bluff, this skill is best used in conjunction with Send Thoughts.

History (Int): this will automatically be high due to the fact that it keys off your main stat. But since Strategist’s Epiphany was nerfed to only affect you, there’s no real reason to train this skill.

Religion (Int): this will automatically be high due to the fact that it keys off your main stat. There's just nothing like outsmarting a Cleric in a religious argument.

Heal (Wis): being a trained healer gives you some leader potential if you're into that, mostly in the form of skill powers.

Stealth (Dex): this rating is for Gnomes, Wood Elves and Shades only (although Shades are naturally trained in it). Starting a combat hidden if you have any cover or concealment is insanely good for a controller, so you could do worse by investing in Stealth. Even more important if you're a Gnome and want to use Unseen Dread consistently.

Acrobatics (Dex): being trained in either Acrobatics or Athletics is never bad, since you're going to face a physical challenge at some point. On top of that, Acrobatics offers some sweet utility powers like Timely Dodge.

Tiefling (CHA+Con/Int): the attack bonus against bloodied enemies and racial power are nice, but it’s the mindblowing feat support that sells the race. Whether you want to optimize psychic damage and vulnerability, blast away with fire damage or focus on charm and domination, Tiefling is the race to be. Tieflings also have their own psionic paragon path in Infernal Eye, and it’s the only Cha-race that can fix an Int/Cha Psion’s initiative problem thanks to Imperious Majesty. And on top of all of that, decent racial utility powers for a controller. I'm not rating any race gold, but it’s certainly the top pick for Cha-Psions.


Kalashtar (CHA+Int/Wis): getting (pseudo) Superior Will for free is a very powerful racial ability. The feat support is limited, but also surprisingly strong for a controller. Bastion of Mental Clarity won’t come into play often, but when it does you’ll be very glad you have it. Also an uncommon +2 bonus to a skill of your choice. In my opinion one of the strongest Psion races.

Deva (WIS+Cha/Int): one of the two Int/Wis races of choice. Good racial features, and Soul of the World is an amazing epic destiny that opens up a wide range of possibilities. In the feat department you have Battle Intuition for an enormous initiative boost, and Radiant Power opens up the radiant abuse gimmick through Morninglord at the cost of a -2 penalty to your attack rolls.

Pixie (CHA+Dex/Int): it’s the ability to fly and to take shelter in your ally’s square that really sells this race. Think for a minute, what is it that a Psion really doesn’t want to do? Answer: be anywhere near his enemies. So you fly to a rooftop, perch there and start messing with people’s minds while they can't reach you. Gets worse at paragon when you start facing more flying enemies who have no problem reaching you. A minor action encounter utility power that turns you invisible is also welcome for a controller.

Githzerai (WIS+Dex/Int): the other Int/Wis race of choice. Very good racial features for a controller. It’s unfortunate that most of the racial support is geared towards melee and classes that regularly get attacked. If Githzerai were more controller centered, they would get the skyblue rating like the Deva. Although Shared Danger Sense is a sexy, sexy feat.

Shardmind (INT+Wis/Cha): the quintessential Psion race, according to the PHB3. Also the only Int-race that gives you the choice of either Wis or Cha as your secondary stat. It has a few interesting feats that increase your striker and leader traits and an ok psionic paragon path, but nothing that really improves your controller capabilities. Still, the stats are perfect, and that is enough for a blue rating. The skill bonuses are also excellent: Arcana, Endurance and a skill of your choice.

Gnome (INT+Cha/Dex): Stealth is the name of the game with this race. Reactive Stealth lets you start combats hidden, Unseen Dread gives you forced movement on top of other effects, and Shadow Skulk lets you stay hidden if you miss. Shaped Consciousness and Dreamwalker also help you to stay out of sight while you make attacks through the eyes of your conjurations. A racial bonus to Stealth helps, and more Arcana is always good. Niche, but very powerful if you can get it to work consistently. Be aware that with only 5 speed, you’d better remain hidden because enemies will have no problem chasing you.
If you don't invest in Stealth, the rating becomes black.

Eladrin (INT+Cha/Dex): aside from good stats, a racial bonus to Will and a great racial power, there’s not much to recommend Eladrin over one of other Int/Cha races. You could get Wand proficiency as a Sun Elf, if you’re into that. And a bonus to Arcana is always useful.

Hamadryad (WIS+Cha/Int): you could certainly do worse than this. Tree Mind and Hamadryad Aspects are solid abilities for a controller, as are some of the racial utility powers. It’s not as well supported as most of the other Int/Wis races, but no-one will fault you for playing a Dryad.

Shade (CHA+Dex/Int): here we get near the bottom of the barrel when it comes to Int/Cha races. If only Shades didn’t get one less healing surge. Being reduced to 5+Con mod surges doesn’t bode well for a controller’s lifespan. But if you can live with that, the race becomes pretty interesting. No other race can hide as well or as easily as this one, they’re even able to use allies for cover. Shaped Consciousness and Dreamwalker let you stay out of sight while your conjuration does your attacking for you, so it's easier to hide again. You're naturally trained in Stealth and receive a bonus to it and Arcana, so that guarantees you'll at least be decent at hiding. In the power department, Shadow Monsters is a nice utility for stacking attack penalties.
If you promise me you’ll be very careful and invest in Stealth, you have my blessing to play a Shade. If you don't invest in Stealth, the rating becomes purple. Also, be aware that Gnomes and Wood Elves do it better.

Changeling (CHA+Dex/Int): as cool as this race is to roleplay, there’s not much to recommend Changelings otherwise. They have a few feats specifically for Psions and psionic characters, but they’re not worth investing in. You take this race purely for RP reasons. characters, but they’re not worth investing in. You take this race purely for RP reasons.

Human (one ability score of your choice): although they don’t get a secondary ability score, Humans are very close to gold. +1 to all NADs, a bonus feat and another class skill training are all very good incentives to play the race, as are some of the excellent feats. But the real treasure for a power-starved class like you is the bonus level 1 at-will power. The powers at this level are already some of the best Psion powers in the game, so getting one for free is extremely good. Although you can’t augment it, most powers are good enough unaugmented to still be effective. And remember, you can always retrain the power when you pick up a power with similar effect at higher levels.
If for some reason you feel you’ll never use the extra at-will power, you have Heroic Effort as the excellent alternative.

Elf (DEX+Int/Wis): when you think of Elves, the first image that springs to mind is the classic archer hidden in a tree. But what if I told you that they also make excellent stealthy Psions? Provided you’re a Wood Elf, you can use your Perception (which you have as a class skill and get a racial bonus to) for initiative, and you have the option of starting combat hidden if you have any cover or concealment. The Communion utility power gives you some leader capabilities, and 7 speed is always useful for a class that doesn’t want enemies near it.
If you're not a Wood Elf, the rating becomes black.

Genasi (INT+Con/Str): although it’s an Int-primary race, Genasi don’t bring much extras to the table. The racial feats are plentiful but mostly useless to you. So really the only question is what manifestation to pick. There are four that have something useful for the Psion: Stormsoul can boost the damage of your lightning and thunder powers with Promise of Storm and gives a Fort bonus; Cindersoul protects you from nasty hits with Firedeath and gives a Fort bonus; Voidsoul gets you out of harm’s way with Void Assumption, has the excellent Scion of Abscence paragon path and gives a Will bonus; Embersoul gets you out of danger with Ashfall Evasion and gives a Ref bonus.

Shadar-kai (DEX+Int/Wis): the racial bonus to Fort and the defensive encounter power are nice. There are also a few very good control effects you can add to your powers during one or two turns with the feats from Dragon 391, but it's a rather large investment.

Warforged (CON+Str/Int): what, you thought Shardminds were your only option for playing psychic constructs? What sells the Warforged as a Psion race is the racial bonus to Will, the defensive encounter power, and most of all the Psiforged Resolve feat which lets you regain a power point when you’re bloodied. Most of the racial support is aimed at melee classes, but you could do worse.

Hobgoblin (CON+Int/Cha): Hobgoblins became a playable race late in the game (DR419). The racial power is absolutely incredible, one of the best defense powers in the game. Unfortunately, there's not much else here for you. The secondary stat is pretty useless, and if you want a racial initiative bonus you should play a Githzerai. The rest of the race is built around using shields in a phalanx formation with allies, and perhaps being mounted. But that's not what a Psion should be doing.

Githyanki (INT+CON): since this is a Monster Manual race, it won’t be allowed at every table. Additionally, its racial features are almost the same as the Githzerai’s but without the boost to your secondary stat. If you want to play a planar traveler, just go with Githzerai instead.

Half-Elf (CON+Wis/Cha): the race gets this rating for one thing, and one thing only: Dilettante. Having an extra encounter power which you can turn into an at-will at paragon is great for a power-starved class like you. You’ll probably poach Wizard powers to pick up an effect that you don’t have in your arsenal yet. Options for those who want to lead are Direct the Strike (or Commander’s Strike if you’re feeling a little suicidal) and Magic Weapon, which you’ll use with a staff and thus requires some suicidal tendencies. Other options include Hand of Radiance (Wis), Magic Stones (Wis), Sacred Flame (Wis), Astral Seal (Cha) and Staggering Note (Cha).
Access to Human feats completes the picture, and makes Half-Elves almost a blue race.

There's another Half-Elf trick that's a bit iffier but gets you two extra power points per combat. Take a Vampire at-will, then take the Adept Dilettante feat so you count as a Vampire. This makes you eligible for the Psionic Vampire feat, which gets you a free healing surge when you hit with an augmented power and lets you spend a surge as a minor action to gain two power points.

Revenant (DEX+Con/Cha): you play a Revenant for access to another race’s support and the amazing (read: broken) stuff you can do with it at 0 HP.

Mul (CON+Str/Wis): an option for a more durable Psion. An additional healing surge and the Incredible Toughness power ensure you’ll keep going longer than any other Psion. You also get a couple of nice racial feats, and of course access to feats of Humans (or Dwarves, but there’s nothing there for you).

Dragonborn (CHA+Str/Con): if you’re desperately looking for damage, Dragonborn could be the race you’re looking for. Io’s Roar inflicts vulnerable 5 psychic to everyone hit by your Dragon Breath. Combined with Hurl Breath and an area burst psychic attack it gives you a sort-of nova round. Another possibility is Draconic Arrogance for extra damage on push and prone attacks equal to your Str-mod. Rod of the Dragonborn makes all your damage match the damage type of your Dragon Breath, which is useful if you're building an elemental blaster (cold, fire, lightning). Beyond that, Dragonfear is a decent but inaccurate racial power for a controller.

Dwarf (CON+Str/Wis): another option for a more durable Psion. Shield Dwarves get free light shield proficiency which you can put to good use, and a minor action Second Wind is never wasted. Speed 5 is a problem though. Only play this if you’re really worried about your durability, but in that case I’d rather play a Mul.

Basic power points: 2.
Total with bonus: 3 (Escaped Thrall or Noble Adept theme)

At this level you get two great powers for Attack Penalties and Forced Movement. The only Action Denial you get here is slow. If you're a Cha-Psion, seriously consider taking Mind Thrust instead of a controller power for the nutty leader-like augment 2.

Sample power selection
Cha-Psion: Dishearten, Mind Thrust
The rest: Dimensional Scramble, Mind Lock

Dishearten (AP): PHB3. The rating of this area burst 1 grows with your Cha-modifier and your available power points. From level 7 onwards, you can use this at least three times per encounter, which means you start shutting down entire combats if you can keep enemies clustered together. If you have only 1 power point left, the augment 1 is nice to give your party some freedom of movement. Be careful though, because it hits your partymembers too. If you're a Cha-Psion, don't be surprised if you find it hard to find a suitable replacement for this at later levels. Less awesome but still good if your Cha is low.
Cha, Psychic, Will

Dimensional Scramble (FM): PsP. A power that’s deceptively good. There will be a time every combat when allies and enemies are clumped together and you can’t use friendly fire powers like Dishearten. That’s when you use the augment 1 or 2 on this and rearrange the battlefield to your liking. If your partymembers already are in optimal position, remember that you can teleport vertically as well! If enemies fail their save, they take an additional 1d10 falling damage and fall prone if they’re not trained in Acrobatics. This power works especially well with with Dreamwalker's level 16 feature to teleport unwilling enemies who are next to your conjuration right into the party's clutches. Or 12 squares up into the air for giggles.

Mind Lock (AD): PsP. Slow one or more creatures, and prevent them from shifting. Nice in the first round to keep distant enemies at bay, good later to keep them next to your defender. Quickly overshadowed by Force Hammer at level 3 though.
Psychic, Will

Mind Thrust: PsP. One of the two ranged basic attack powers at this level. Although it doesn’t offer any control, the augment 2 paints a big, bright bulls-eye on one enemy’s back. A great option if you have another good controller in your party, you lack a leader (or have one that grants mulitple attacks per round) or if you want to teach your party how to focus fire.
Cha, Psychic, Will

Static Mote (AD): PsP. Auto-slow in an area burst 1 is pretty good! Especially early in the fight when enemies are still at the other side of the map. Too bad it’s very easy for enemies to escape the damage by taking a run or double move action. The damage becomes more reliable in smaller rooms, but also more dangerous since it hits you and your allies. Works with Mark of Storm.

Memory Hole (AD): PHB3. Simply make yourself invisible to one or more enemies. An important power for Gnomes, Wood Elves and Shades who invest in Stealth and want to stay hidden, but very mediocre for everyone else.
Psychic, Will

Kinetic Trawl (FM): PHB3. One of the two ranged basic attack powers at this level, and not the good one. Forced movement is fine in principle, but there’s only a single type of enemy you should be pulling towards you (Controllers who are hiding in the back rank). Better for Shapers and Dreamwalkers who can send their conjuration off to the other side of the map to pull enemies away from the squishies.
Wis

Force Punch (FM): PHB3. only useful as a last resort power when you somehow find yourself surrounded by enemies. Better for Shapers and Dreamwalkers who send their conjurations into melee to push and prone enemies.
Wis

Force Shard (SC): PsP. You can sort-of block a square with this, but the penalty for moving through the force shard (Cha-mod force damage) won’t deter anything but minions. It’s been nerfed to only deal damage once per turn, so no abusing this with forced movement. If you want to do normal damage with Force Shard, you have to spend another minor action. If you really want zone control, wait until level 3 for Burning Flux.
Cha

Basic power points: 4.
Total with bonus: 5 (Escaped Thrall or Noble Adept theme)

Cha-Psions get a single target control power which they might just keep until level 23. There are also some interesting Action Denial powers (one of which is a strict upgrade from level 1), and a zone which can damage multiple times per turn.

Sample power selection
Cha-Psion: Betrayal, Dishearten, Mind Thrust
The rest: Force Hammer, Dishearten, Dimensional Scramble

Betrayal (FM, AD): PHB3. Unaugmented this does nice damage, but unless the monster you’re charming has a melee basic attack with an awesome control effect (unlikely), it doesn’t help you control the battlefield. That changes when you use the augment 2. Forced movement and dazing is a powerful combination, and there’s a good chance the monster will do a lot more damage than you. Strong single target control which gets better at higher levels. Can also be used to trigger your defender's mark for even more damage, although the attack is made with a -2 penalty.
Cha, Will

Psychic Anomaly (FM, AD): PsP. A possible replacement for Dimensional Scramble. You pick a crowded area, plop down a potential flanking partner for your allies and start rearranging the battlefield to your liking. Too bad you need to spend two power points each time you want to daze an enemy, because forced movement and daze is a powerful combination. Also works better with damaging zones than Dimensional Scramble, because you can slide enemies in and out of the zone for autodamage.
Psychic, Will

Force Hammer (AD): PHB3. Did you take Mind Lock at level 1 and don't see another good power at this level? Then retrain Mind Lock away for another level 1 power and take Force Hammer instead if you want the slow/no shift effect. Unless you want psychic damage for Psychic Lock or attacks vs. Will for Life Singer or Divine Oracle, but those don’t come online until paragon.

Fuse Form (SC): PsP. The unaugmented version basically does nothing at all. The augment 1 version is interesting in that it gets the Fear keyword (Starfire Womb, Hellfire Blood, Stygian Adept). It’s the augment 2 version that saves this power though. If you can catch two or more enemies in a burst 1, they’re staying there while your party finishes off the monsters on the other side of the map. Gets much better at higher levels when you have the power points to sustain the augment 2 over multiple rounds, although it gets competition from Thunder Tether at level 13. Too bad the damage is pitiful.

Burning Flux (SC): PHB3. Better than Force Shard from level 1 because it blocks a wider area, but non-minions can still just walk through it and ignore the pitiful damage. The augment 1 gives enemies a better reason for moving through the zone because it blocks line of sight. The augment 2 enlarges the totally obscured zone so artillery won't have a choice but to walk through it in confined areas.
Wis

Kinetic Trip (AD): PsP. The more flexible targeting of the augment 2 is nice, but not enough reason to pick this over Force Hammer.

Crushing Turmoil (AP): PsP. Unless you or a partymember has some really nasty save ends effects that you want to keep going round after round, just ignore this in favor of Dishearten.

Id Insinuation: PHB3. A leader power, but for some reason it only lowers the target’s Fortitude. You might be interested in this if you have a party full of implement attackers who target Fort and are short a leader, otherwise you can safely skip this. It doesn’t help that the power itself targets Will.
Cha, Psychic, Will

Basic power points: 6.
Total with bonus: 7 (Escaped Thrall or Noble Adept theme)

At this level you get your sixth power point so you can use augment 2 powers for as long as most combats (should) last. Wis-Psions get access to some good powers, one of which is the best Forced Movement Psion power, so they can finally match their Cha-counterparts. Also a good immobilizing Action Denial power for everyone, so it's not necessarily a dead level for Cha-Psions.

Sample power selection
Cha-Psion: Force Grasp, Betrayal, Dishearten
Wis-Psion: Dread Spiral, Force Hammer, Dishearten
The rest: Force Grasp, Psychic Anomaly, Dishearten

Force Grasp (AD): PHB3. The next one in the line of force-based slow/prone/immobilize powers. Immobilize gives you some hard action denial, against two targets within 10 no less, and it doesn’t even require a secondary stat. A great pick for every Psion. Replace Force Hammer or Mind Lock with this if you have either power.

Dread Spiral (FM): PHB3. A good forced movement power for Wis-Psions, who should replace Kinetic Trawl or Force Punch with it if they have either power. The unaugmented and augment 1 version are ok because it's a forced movement attack vs Fort, which means that you can easily pull the flimsy caster or artillery from the back row next to the defender. The augment 2 version amps the forced movement way up. Additionally, there's no better power yet for abusing damaging zones. Useless for Cha-Psions.
Wis

Kinetic Buffer (FM): PsP. This is the power all you Shapers have been waiting for. Put your conjuration down in the middle of melee and start throwing enemies around the battlefield. The defense bonus insures that your conjuration stays intact long enough to do it again next turn. The same goes for Dreamwalkers of course. You replace Force Punch with this if you have it. If you’re neither Shaper nor Dreamwalker, you’ll only use this as a last resort when you find yourself surrounded, which should be almost never.
Wis

Cranial Disturbance (AD): PHB3. The rating is for Wis-Psions who want some single target control, but it has fierce competition from Force Grasp. You replace Force Hammer with this if you have it, but be aware that Cranial Disturbance is not strictly better. Too bad the extra damage from the augment 1 and 2 hits all creatures instead of just enemies, because chances are your allies are next to a target you’d like to prone or daze. The power is red for Cha-Psions, who will stick with Betrayal instead.
Wis

Ego Whip (AP): PsP. A nice debuff power for defenses as well as attacks, and even saving throws if you augment it. Too bad it’s only against one target and the damage is pitiful, so your partymembers better make good use of the defense penalty. Better if you or your partymembers deal in a lot of save ends effects or if you have a way to make use of the Fear keyword (Starfire Womb, Hellfire Blood, Stygian Adept). Red for Cha-Psions, who will stick with Dishearten and Mind Thrust for these types of effects.
Psychic, Will

Mind Break: PHB3. A ranged basic attack that only does damage and applies psychic vulnerability. It allows you to pursue the path of a striker, or leader if your partymembers also do psychic damage. For those roles I’d rate this blue, but since you’re supposed to be a controller black is the best I can do. Gets better if you have an RBA-granting leader, since you can apply Psychic vulnerability out-of-turn and immediately use it on your own turn.
Cha, Psychic, Will

Ectoplasmic Servant (AD, SC): PsP. A possible replacement for Static Mote if you’re into auto-slowing, but at this level you can do so much better. It only damages enemies, so it has that going for it. Also has some soft control, but since the damage is only once per turn it’s useless for zone pingpong. Only take this if your whole party has World Serpent´s Grasp or other ways to take advantage of slowed enemies.

Matter Dissipation (SC): PsP. Like most soft control powers, the low damage simply won’t deter any non-minion from staying in the zone. It’s really a testament to how bad Insidious Doubt is that this is still rated above it.
Cha

Insidious Doubt (SC): DR390. Yikes, this is a bad power. Only one target, soft control for some of the least used action types, and worst of all no augment 2. You could try to double-tap psychic vulnerability with this, but really, why would you even bother.
Cha, Psychic, Will

Basic power points: 7.
Total with bonus: 10 (Escaped Thrall or Noble Adept theme, psionic paragon path)

You’re now getting to the point where you have to make some serious considerations if a new power is better than any other power you already have access to. Augment 4 is a high price to pay, especially if you didn’t take a psionic paragon path. So be very sure if the power you’re taking is worth losing a power that only takes 2 power points to augment.
This level is all about Action Denial through movement control. It also offers a nice Forced Movement power for Cha-Psions, a concealment/blinding power for Stealth builds and the only Psion power in the game that deals radiant damage.

Sample power selection
Cha-Psion: Thunder Tether, Betrayal, Dishearten
Wis-Psion: Thunder Tether, Dread Spiral, Dishearten
The rest: Thunder Tether, Dimensional Scramble, Dishearten

Thunder Tether (AD, SC): PHB3. Now this is control! The augment 1 corrals two monsters in a 5x5 zone where they won’t bother (or run from) your party for a round. Leaving the zone is impossible, so it even gets around stuff like teleportation that immobilize and slow can’t deal with. The augment 4 is soft control, but depending on how you good your Wis is, this can do a lot of damage when you combine it with forced movement. Every instance of forced movement deals thunder damage, so you can abuse this with non-standard action forced movement powers like Forceful Push and Hand of Caution. Also synergizes very well with Mark of Storm. You can replace Force Grasp with this to make room for another level 3-7 power.
Wis

Kinetic Wave (FM, SC): PsP. Thunderwave is good. A Thunderwave that leaves behind a 3x3x3 or 5x5x5 zone of difficult terrain is better. Unless you’re fighting in a wide-open space, this does a good job of getting the monsters off your party’s back. Be mindful that it’s party-unfriendly and that you have to approach melee to use it. Better for Shapers and Dreamwalkers who use it from their conjuration’s square.
Wis

Inexplicable Attraction (FM, SC): PsP. This power is good in that it actually has a useful effect when you’re out of power points. Although the slide is limited to a square adjacent to another creature, sliding one or two targets 3-5 squares can save you from an ambush or draw unwilling casters and artillery next to the striker and defender. The augment 4 has a little soft control baked in, but as usual the damage is far too low to be an effective deterrent. Also interesting is that this is a Wis-power that deals psychic damage for Psychic Lock.
Wis, Psychic, Will

Void Shard (AD, FM): PsP. An almost strict upgrade of Static Mote. All the separate effects of this power aren’t very impressive, but they combine to make quite a decent action denial power. So if you like auto-slow and large area action denial, Void Shard will serve you well.

Brilliant Thought (AP): PsP. The unaugmented and augment 1 version are only good against artillery that don’t have burst powers, so in other words extremely limited. The black rating comes from the fact that the augment 4 lets you attack all targets in an area burst 1 twice, and if you manage to hit an enemy twice it's blinded. It’s also the only Psion power that deals radiant damage, giving you an entry pass into the Radiant Mafia. If you attack at least two targets with radiant vulnerability twice per round, your damage output starts to approach striker levels. Finally, I'll mention the usefulness for Gnomes, Wood Elves and Shades who are built around Stealth and want concealment to remain invisible.

Dual Hallucination (AD): PHB3. This power deals psychic damage to two targets at large range, but unfortunately only the augment 4 has any control effect. It’s a good replacement for Mind Thrust if you have a party full of Deft Blade users and implement users who attack Reflex, an alternative to Inexplicable Attraction for Psychic Lock users who love the range and the multitargetting, or an upgrade from Cranial Disturbance for ranged dazing.
Cha, Psychic, Will

Telepathic Wail (AD): DSH. When I heard about a new Psion power coming out, I kinda hoped it would do more than deafen your targets. The unaugmented version has a very niche use for Shapers and Dreamwalkers who want to make a Stealth check out of sight after their conjuration has deafened everyone for a -10 Perception penalty. The usefulness of the augment 1 and 2 completely depend on the enemies you’re facing. Good if you plan to fight Mindflayers and other psychic scum, otherwise completely useless.
Psychic, Will

Mind Wipe (AP): PHB3. Mind Wipe is a fine power in it’s own right. It just has one little problem: aside from doing a little more damage, it’s completely overshadowed by the level 1 power Dishearten. And that earns you a red rating, especially as a level 13 power.
Cha, Psychic, Will

Concussion Burst (AD): PHB3. Terrible damage, and prone is a very underwhelming status effect at this level. Not to mention that the level 3 power Force Hammer does the same, is more versatile and actually has a damage roll. At this level you can afford the 2 power points necessary for Force Hammer to prone, so pick up a power that actually does something instead.

Basic power points: 9.
Total with bonus: 12 (Escaped Thrall or Noble Adept theme, psionic paragon path)

Psions who go for control can safely skip this level, since every single control power is just bad. If you’re looking for a third at-will power with a slightly different effect however, there are two very good leader powers here for you to take. Especially Forced Opportunity can completely change your playstyle and will make your Warlord green with envy. You can also get an at-will zone abuse power if you're optimized for Forced Movement.

Sample power selection
Cha-Psion: Forced Opportunity, Thunder Tether, Dishearten
Wis-Psion: Shield Crack, Thunder Tether, Dread Spiral
The rest: Forced Opportunity, Thunder Tether, Dimensional Scramble

Forced Opportunity: PHB3. Wait, what? Since when do Psions grant free attacks to allies? Well, they do now, and they do it splendidly. This power instantly turns you into a Lazylord by letting one ally attack with a big bonus (unaugmented) or letting the party murder one creature outright (augment 4). You know what they say about control: dead is the best status effect, and this power goes a long way towards making that happen. In some fights, this is the only power you’ll be using. The rating is obviously lower if you don't have many good opportunity attackers in your party.
Cha, Will

Shield Crack: PHB3. It took a while, but finally Wis-Psions get their own Mind Thrust. No control effect, but an area burst 1 that lowers AC is pretty good. Especially since it targets Reflex, usually not the highest defense of those annoying soldiers. The augment 1 makes it partyfriendly, which is pretty rare for a Psion! The augment 2 also lowers Reflex, which means this power becomes more accurate the next time you use it against the same targets. Does lightning damage, so works with Mark of Storm. Purple for Cha-Psions with Mind Thrust.
Wis

Cerulean Cage (SC): PsP. Great, so you can deal a few extra damage to a target if it leaves its square? That will deter absolutely no-one. The augment 4 is the reason you take this though. It's the only at-will power in the Psion's arsenal for zone abuse, which you achieve by sliding the target in and out of the damaging zone multiple times (with Dread Spiral for example). Doing multiple instances of your Int mod damage will get a monster bloodied quickly, especially if you apply vulnerability to force damage. That's pretty hard to find, but Concussive Detonation at level 27 will do it.
Wis

Telekinetic Haze (AP, FM): PsP. Compares infavorably to the level 7 power Kinetic Buffer. The augmented version on that one is larger, cheaper to use and combines the forced movement with the defense bonus so you won’t have to choose between the two. The only ones who want this power are Gnomes, Wood Elves and Shades who try to remain hidden and let their Shaper/Dreamwalker conjurations do their attacking for them.

Psychic Brand: PHB3. Another leader power which makes it impossible for enemies to stay invisible and applies vulnerability with the augment 4. Not necessarily a bad power, but not a controller power either. If you want a damaging leader power, take Forced Opportunity instead.
Cha, Psychic, Will

Thought Guardian (AP, AD): PsP. Let’s make this clear right now: the unaugmented and augment 1 version should never be used in favor of Dishearten. The augment 4 is usable in the first round if you win initiative and place the conjuration right behind the monsters, but that’s about it. Since you run the risk of the monsters avoiding the opportunity attacks by teleporting or just using ranged attacks, this power doesn’t deserve a higher rating.

Manifested Horror (SC): PsP. Another bad soft control power. This would actually look interesting on a defender for a nice Catch-22, but since you’re a controller and your enemies will have HP to spare, dealing Int mod damage won’t influence their actions much. Has the Fear keyword for Starfire Womb, Hellfire Blood and Stygian Adept, but you should go with Ego Whip instead if you’re into that.
Psychic, Will

Crystalline Bonds (AD): PHB3. Seriously, no damage? With a level 17 close blast 3 immobilize? Although there’s only one other at-will that immobilizes (Force Grasp at 7), it completely overshadows Crystalline Bonds with its more flexible targeting and damage.
Wis

Basic power points: 13.
Total with bonus: 16 (Escaped Thrall or Noble Adept theme, psionic paragon path)

Three great control effects here (dominate, removed from play and area blindness). The rest of the powers suffer from the psionic power syndrome: they're just not good enough compared to lower level powers. Although Phantom Burden is an option for Psions who tend to run out of power points before the fight is over, since it's the only power with a good control effect that doesn't cost 6 power points.

Sample power selection
Cha-Psion: Sudden Control, Thunder Tether, Dishearten
Wis-Psion: Mindfire Explosion, Shield Crack, Thunder Tether
The rest: Mindfire Explosion, Forced Opportunity, Thunder Tether

Sudden Control (FM, AD): PHB3. You can finally do what telepaths do best: take complete control over another’s mind. The unaugmented version is an upgraded Betrayal (bigger slide, target can attack itself, melee or ranged (OA!) basic attack, bonus to attack and damage rolls), and the augment 6 lets you outright dominate the target. On its turn you make the target charge another enemy or run off a cliff, taking as many opportunity attacks from your allies on the way as possible. And next turn, you get to do it again. There’s a reason you waited so long for this ability.
Cha, Psychic, Will

Mindfire Explosion (AP): PsP. The unaugmented and augment 2 versions will annoy bunched-up artillery, but not much else (Gnomes, Wood Elves and Shades like it for hiding though). The augment 6 blinds in a large area burst, which can just shut down combat for a few rounds. Great for Wis-Pions who want their share of attack penalties. If you like 'em blind, replace Brilliant Thought with this. A bit overshadowed by Psionic Veil at 27 though.
Will

Space Vortex (FM, AD): PHB3. The teleport is useful, but the low damage is unacceptable. The augment 6 provides incredible control though: nice damage and the enemy is removed from play for a round, no questions asked. This power drops to red for Cha-Psions who take the dominate effect instead. If you’re a Cha-Psion, you only pick this up if you really need the teleport effect or you like Betrayal better. Though I have to say, dominate is so strong that even Wis-Psions should probably still take Sudden Control over this.

Phantom Burden (AD, SC): PsP. One of the few powers with an augment 6 that’s actually worse than the augment 2. Applying slow and difficult terrain in an area burst 2 will keep most monsters off you for at least one round, whereas making them fall prone after they’ve moved next to you will only give them a -2 penalty to attack. If the augment 6 did something cool too, this power would earn a higher rating.

Daggers of Pain (SC): PHB3. The unaugmented and augment 2 version are just worse versions of Mind Break (which doesn’t even have a control effect to begin with). If you want to trick out this power, it’s hard but possible to build around the augment 6. The Praetor Legate level 16 feature lets you slide all targets adjacent to you one square at the start of their turn (which can be increased with Controlling Advantage for example). You can also ready Dread Spiral or a similar forced movement power for when the enemy starts its turn.
Cha, Psychic, Will

Prismatic Swarms (AP, FM): PsP. Adding a slide to an unaugmented Dishearten is nice, but not being a psychic power (thus not triggering Psychic Lock) is what kills the rating on this. Maybe purple for Wis-Psions, but they should still take Mindfire Explosion over it if they’re interested in applying attack penalties.

Mind Trap (AD, AP, SC): PsP. If you want to prevent enemies from taking out-of-turn actions, you're much better off just dazing them. Dual Hallucination already gave you a multitarget daze that deals psychic damage at level 13, and is more versatile to boot, so you should just stick to that.
Cha, Psychic, Will

Cruel Crush (AD): PHB3. Single target proning at level 23, blegh. The range is good, but that’s about it. The augment 6 is like a single target slow + attack penalty, which isn’t nearly enough to even consider taking this power. Stick to Force Hammer for your proning needs.

Basic power points: 15.
Total with bonus: 18 (Escaped Thrall or Noble Adept theme, psionic paragon path). 20 if you took the Topaz Crusader epic destiny.

And we finish with some Action Denial and Attack Penalties in the form of area stun and invisibility/blindness. Apart from those powers, there’s not much else to consider. But that doesn’t really matter, since you have your full selection of at-will powers by now.

Sample power selection
Cha-Psion: Psionic Veil, Sudden Control, Forced Opportunity
Wis-Psion: Concussive Detonation, Thunder Tether, Dimensional Scramble
The rest: Concussive Detonation, Mindfire Explosion, Forced Opportunity

Concussive Detonation (AD): PHB3. Close blast 3 slow, force vulnerability or stun. That’s a nice set of effects to apply in a blast, especially the stun. The best part is: once you get a bunch of enemies in the blast, you can keep hitting them with the stun for as long as you have power points; I mean, they’re not going anywhere. If you are still carrying around Mind Blast from level 9, you can finally exchange it for something else now.
Wis

Psionic Veil (AP): PHB3. If you position yourself (or your Shaper/Dreamwalker conjuration) and your partymembers correctly, you won’t even have to use the augment 6 on this. You being invisible or them being blinded has practically the same effect (-5 attack penalty for melee and ranged attacks, -7 with Psychic Lock), so you can save a lot of power points that way. If you took or wanted to take Mindfire Explosion at level 23, you can now take this instead. Again, good for Gnomes, Wood Elves and Shades who want to stay hidden.
Psychic, Will

Kinetic Detonation (FM): PsP. A large or even VERY large burst that pushes enemies out of it has its uses. You probably don’t want to use a precious at-will slot for a power that does only that, but if you do, Kinetic Detonation is there for the taking. It’s an alternative to Kinetic Wave for Psions who are tired of wading into melee to use a good forced movement area power.
Wis

Decerebrate (AD): PsP. The unaugmented version does nothing but be a ranged basic attack. The augment 2 has very weird targeting (one creature in an area burst 1?), but taking a move action away from a creature is nice as a form of semi-daze. The augment 6 dazes three enemies with psychic damage, which is a nice upgrade from Dual Hallucination’s two targets at the cost of two more power points. Not much more to tell about this decent but wholly unimpressive power.
Psychic, Will

Intrusive Spear: PHB3. I guess the designers were out of inspiration, since this power does exactly the same thing no matter how many times you augment it. And that thing (making targets grant combat advantage) isn’t even good. Stick to Mind Thrust or Shield Crack if you want to make a target easier to hit.

Claws of Force (AD): PHB3. This power was good as the level 7 Force Grasp, but 20 levels later I really expect better than single target slow/restrain and some weird form of movement denial. It’s even worse than Force Grasp due to the limited targeting and the huge amount of power points you have to spend for hard movement denial.

Reality Meltdown (SC): PsP. Theoretically, if you can keep enemies bunched up next to each other, you can deal Int+Int/1d6+Int/2d6+Int fire damage to each enemy once per round by moving the molten orb into their squares. But if the enemies are already in that set-up, why not just use a nice area burst or close blast that actually does something useful?

Hail of Crystals (SC): PsP. A “damned if you do, damned if you don’t” power. Except that the zone is too small and that nobody cares about the piddly damage to be deterred either way. Could be used to clear up minions, but do you really need this turd of a power for that?
Cha

Only two powers with any decent control at this level, so if you want to do your job right the choice ain’t hard. If you’re looking for a bit more damage instead, you have some mediocre options.

Living Missile: PsP. Look at the control on this one! Immobilize or slow for action denial, slide 10 for massive forced movement and prone as icing on a sweet, sweet cake. You can easily take one or two melee targets out of the fight so long as the primary target doesn’t save. This power is absolutely worth getting save penalties like Crushing Turmoil or Ego Whip for so you can also sustain this on elites and solo’s. Don’t forget that you can also slide the enemy into dangerous terrain instead of into his buddy. This power gets bonus points for great top-down design.

Hand of Caution: PHB3. Annoying the hell out of one enemy by pushing him around is a lot of fun. Unfortunately that's the only control this power offers.

Summon Thought Servant: PsP. Summon a speedy ally that can attack and put dying allies back on their feet, or at least stabilize them. Too bad it costs you a power point to really make this summon do something worthwhile, which isn't something you can easily afford at this level. Also has no control effect besides putting another guy on the battlefield.

Mental Trauma: PHB3. Damage and vulnerability at level 1 can quickly get rid of one enemy. But unless it’s a solo or dangerous elite and your partymembers also do psychic damage, there are better powers out there.

Psychic Dissolution: PsP. The power effectively gives your defender and other allies adjacent to the target concealment against it. Interesting but not worthy of a daily power.

Telepathic Projection: PsP. On each of your turns, the target is hit with an unaugmented Betrayal as long as it doesn’t make its save. Depending on the target’s damage and reach, this could be fun. Unfortunately you don't get a secondary effect at all if the target makes its first save. The miss effect is also annoying, if not outright dangerous to your partymembers. The control this power offers depends entirely on the effects of the target's MBA, so practically none.

Telekinetic Anchor: PHB3. This unfriendly area burst 1 offers some soft control, but not enough to raise any eyebrows.

Ravening Thought: PHB3. This would’ve been much more elegant as an area burst 1. It still wouldn’t be good, but it would be elegant.

Fortunately you get a much better selection here than at level 1. Almost every flavor of control is present: prone, grab, immobilize, slow, daze and forced movement are all available, and every effect has a good power.

Force Spheres: PsP. Although knocking enemies prone isn’t the most amazing of control effects, it’s far from the worst. Now imagine getting that ability as a minor action, four times per encounter, at range 20 with good damage attached. We'll also throw in a free untyped +2 bonus to all defenses. Too bad it's a do-nothing standard action to activate. You want to use this round one but that's the round you should throw your best control effect at 'em. And a single target prone shouldn't be that effect.

Summon Ebony Stinger: PsP. A summon that grabs, now that’s interesting! You always augment it of course, since escape checks against its Fortitude are laughably easy otherwise. Try to grab weak-looking targets (preferably ranged attackers) who don’t have Athletics trained to ensure the grab is sustained. An opportunity attack that inflicts ongoing damage is a nice bonus.

Inflicted Mindscape: PsP. A friendly area burst 1 save ends immobilize is a great thing to have, especially when it leaves a slowing zone behind. Be aware that the zone slows until the end of the enemy’s next turn instead of yours, so the enemy doesn’t start its next turn slowed when it saves against the immobilize.

Hypnotic Pulse: PHB3. BAM, you’re dazed! Fortunately this is enemies only. Too bad the miss effect doesn’t do half damage.

Crisis of Identity: PHB3. Unaugmented Betrayal with damage stapled onto it. If you make the target attack itself, this power does some very nice damage.

Telekinetic Maul: PHB3. If you really can’t wait until level 7 to get your hands on Dread Spiral, I guess there’s always this. You do get to use the coolest dice though, three of them no less.

Thunderous Exit: PsP. An interesting escape power in a huge area. Unfortunately it's unfriendly, so you're bound to include some allies in the attack. Better for Shapers/Dreamwalkers who can use their conjuration to pick the most ideal spot for the burst.

Shredding Ribbons: PHB3. An unfriendly zone that does negligible damage once per turn, and you need a minor action to sustain it? No thank you.

Like level 1, there is only one good choice at this level. You might look back to level 5 if you don’t like Mind Blast, but I have no idea why you wouldn’t.

Mind Blast: PHB3. No damage, but stunned save ends (dazed until end of next turn on a miss) in a close blast 5 is ridiculously powerful. This allows you to simply shut down one encounter per day, no questions asked. No other power at this level even comes close. Unfriendly, so wait until your allies have left the blast area before you unleash it. Even better for Shapers and Dreamwalkers.

Clear the Slate: PHB3. Instead of stunning enemies from up close, you can slide them from a distance. Not quite the same effect, but Wis-Psions could get some serious mileage out of this by laying down an augment 4 Cerulean Cage and action point with this to add around 30 extra damage to each target hit. Or before level 17, just throw them off a cliff.

Inflict Pain: PsP. The guy who named this power should take another long look at what “pain” constitutes at level 9, because 2d6+Int and ongoing 5 damage isn’t it. Sure, it’s an area burst 2 that slows, but nothing to go wild over.

Sensory Onslaught: PHB3. A single target debuff with attack penalties is nice against annoying solos. If you face a lot of those, you might consider taking this.

Summon Phantasmal Killer: PsP. Putting another body on the field is usually pretty good, but if that body unsummons itself once its target is gone, not so good. The control is decent enough to keep this above red though: -2 attack penalty save ends and psychic damage (so Psychic Lock) shuts one enemy down pretty effectively.

Echoing Boom: PsP. This gives you something to with your minor and immediate action. Not much, mind you, but adding a Mark of Storm effect to one attack per round is still something.

Malicious Lightning: PsP. So much has to go right for this power to reach its potential (which is just dealing some extra damage), and it’s simply not worth the effort. You might try it with Mark of Storm, but I wouldn’t bother. A little better if your defender locks down enemies around him.

Mind Cannon: PHB3. A weird not-area-burst attack that pushes one target one square and deafens it? No. Thank. You.

Most Psions upgrade Living Missile or their level 5 power to Living Barrage here and call it a day. If you’re going for forced movement optimization you could take Imprison, but after that the well runs dry.

Living Barrage: PsP. Seriously, the amount of fun you can have with this power is almost criminal. Area burst 1 immobilize is already good, but then throwing everyone around the battlefield for multiple rounds leaves you in total control. If your party times their initiative right (between the enemies and you), the immobilized/slowed/prone foes will never get a chance to attack in melee. Oh, and for Dreamwalkers this is just ridonkulous.

Imprison: PHB3. Like the level 9 power Clear the Slate, but this trades one square of forced movement for immobilized save ends. Trading up, I’d say. Like Clear the Slate, this is also good with Cerulean Cage.

Dominate: PHB3. Dominate is still a rare ability at this point of the game, and making it save ends is sweet. Too bad it’s single target, and that the miss effect doesn’t also dominate, but it's rare enough to still earn a good rating.

Psychofeedback: PHB3. You daze two targets at range, which is useful at the start of combat. They also give you temp HP if they don’t attack you, which is a nice bonus I guess. Would be better if it did anything besides damage on a miss.

Summon Thought Warrior: PsP. This power lets you act as a proxy defender, which is nice if you absoposilutely need one. If you stick this to an annoying artillery or skirmisher, it's gonna have a hard time getting away from it. Still costs you your standard action to keep up the mark though.

Forced Serenity: PsP. This power masquerades as a soft control power (don’t attack or take 10 damage!), but seriously, what are they going to do, not attack until they save? You use this power when you face a group of multi-atttackers or creatures who use bursts and blasts. When your DM is partial to dragons, you could do worse than this.

Thoughts of Unmaking: PsP. A lot of ongoing damage that could get out of hand quickly if you and your allies manage to bloody the target. It’s should be most effective against targets with a lot of HP like elites and solos, but unfortunately they get bonuses to saving throws, making them actually the worst targets. Since standard monsters die too quickly, this power is something you should skip unless you deal in saving throw penalties.

Crushing Bludgeon: PHB3. A single target implement attack vs. AC. That slows. But wait, it deals 4d10 damage! 4d10!!!
Luckily there’s no rating lower than red, because this waste of space would've gotten it.

No stand-outs at this level, but it’s not so bad that you have to look back to earlier levels for a good choice. Another decent summon(s), mass restrain, forced movement and removing enemies from play makes for a nice set of powers.

Summon Mind Weirds: PsP. This puts three Phantasmal Killers on the battlefield, which is quite the wall of fur (scales? ectoplasm? whatever). Too bad they unsummon after their prey dies, but getting three standard actions for the price of one and a bunch of opportunity attacks is good enough. The augment 1 is a pretty useless bonus, although you can afford the power point by now.

Flowing Terrain: PsP. You bind a bunch of enemies to the ground, literally. This friendly close blast 5 sets up a much safer battlefield for your allies to fight on.

Shred Reality: PHB3. Your allies should grit their teeth when you use this because they’re going to get hit by it, but the effect is worthwhile: you rearrange a huge area to your own liking, and remove the most dangerous target from play for a round. As always, don’t forget you can teleport vertically for 1d10 falling damage and prone.

Force Cube: PsP. This obviously top-down designed power lets you take one enemy out of play for a round, hit or not. His buddies can start hammering the Cube to free him, so it’s perfectly possible you never get to make the secondary attack. But hey, in that case it deals some extra damage and it has absorbed a couple of attacks which otherwise would’ve gone to your party, so that’s also good.

Psychic Leech: PHB3. A double-hitter that lets you gain a power point and some temp HP. This would’ve been good at lower levels, but at this stage one power point won’t make much of a difference.

Cerebral Phantasm: PsP. Some forced movement and something to do with your immediate action as long as the target doesn’t save. Nothing truly bad about this power, but there are just so many superior options available at this point.

Psychic Crush: PHB3. If you want to daze in an area burst 1, just pick up the level 5 power Hypnotic Pulse. The ongoing damage isn’t worth the unreliability.

Crisis of Breath: PHB3. Single target ongoing damage, that’s all. No control and no area effect relegates this power to the realms of red.

Not a bad level! You finally get a large controlling zone, another dominate (save ends this time), another good summon, and a power that quickly becomes one-shot-one-kill if you have a hard-hitting striker in your party.

Far Realm’s Embrace: PHB3. This is the face of true control. It’s a wordy power, so lemme summarize it for you: 7x7x7 burst which deals psychic damage+ongoing, restrains, and leaves behind a sustainable zone that deals damage, immobilizes and pulls targets as an opportunity attack. Unless you’re fighting a group of teleporters, it’s unimaginable that this doesn’t simply win you the encounter.

Thrall: PHB3. If you hit with this, the target can look forward to spending at least a couple of turns under your control. So make it do running charges across the map to its allies, drawing as many opportunity attacks as you can. A good power power to add to what by now can be a robust arsenal of dominate powers.

Summon Emerald Terror: PsP. You summon a large dude that gives everyone adjacent to it a -2 to hit and has a sweet attack. Repeatable Kinetic Bursts which prone are awesome, and could very well be worth spending your standard action on over the course of multiple rounds. The augment has the strange effect that it makes the Emerald Terror give out saving throw penalties when it hits with a melee attack, which is useful if you’re into that sort of thing.

Mind Switch: PHB3. Stun save ends is always handy to have around in a fight, even if you get repeatable stun two levels later. This power mostly suffers from the fact that you also get access to Thrall, since dominate >> stun.

Recall Agony: PsP. Getting an immediate attack as a Psion is already good, since you rarely have use for your immediate action. If you want this power depends entirely on your party. If you have a couple of wimpy strikers or blasters, the ongoing damage won’t be impressive. However, if you have a Barbarian that regularly uncorks daily powers that deal over 200 damage on one hit, this becomes a quick death sentence for all but the toughest solos. You should know when you want this.

Forest of Exclusion: PHB3. Another emergency red-button power that keeps enemies off you and gets better when you’re a Shaper/Dreamwalker. I suppose the zone is meant to keep enemies from approaching you, but the penalty for entering it is negligible. Although combat advantage is always nice to have.

Thought Hammer: PHB3. Although prone is a lame status effect, being able to shoot three flyers out of the sky can come in handy occasionally. Plus, d12s!

Telekinetic Bombard: PHB3. This power is unimpressive by itself. When you take into account the fact that Summon Emerald Terror does the same but with many more benefits attached, there is no reason to take this power.

No standouts at this level, and you could be forgiven for looking back to earlier levels for a better choice. That said, you do get a ginormous zone here, which should be your signature move as a controller.

Ravenous Singularity: PsP. It seems only fitting that as your capstone daily power, you get the ability to summon a friggin’ black hole onto the battlefield. The area of effect is HUGE (11x11x11), and although it doesn’t deal damage it’s difficult to escape since it immobilizes or slows. If you have any saving throw penalties in your arsenal, now would be the time to apply them: any creature that fails its save against the immobilize/slow is eaten by the black hole, removing it from play. Unfriendly and a little unreliable, but still the top pick at this level.

Hurl into Heaven: PsP. Hit or miss, you pick up your enemies for a turn, leave them restrained in mid-air, and smash them back to the ground at the start of your next turn. Nice to clear up a cluttered battlefield for a turn. This power is a little confusing against flying enemies, but you should consult your DM when that becomes relevant.

Soul Break: PHB3. Another single target save ends dominate power. This is actually much worse than the level 25 Thrall power, since you don’t want to give enemies a choice of taking damage or becoming stunned (guess what they’ll pick?). So if you don't have Thrall yet, pick that power over this one. If you do, and you want another dominate power, you could do far worse than this one.

Clasp of the Psion: PHB3. This power is decent enough on its own, and one of the few reasons to get some force powers in your arsenal since you can keep enemies immobilized for a good long time. Too bad it’s overshadowed by Ravenous Singularity.

Microcosm: PHB3. I appreciate the flavor behind this power. That said, this should just stun the target and get it over with. Applying three different save ends effects, of which only one is relevant, is just annoying and unnecessary.

Consuming Psychosis: PsP. This power could be decent in theory, but unless your partymembers GTFO, they run the risk of taking a free attack to the face at the start of the targets’ turns. Not exactly what I call good control.

Tear the World: PHB3. Damage+ongoing in an unfriendly close blast 5, with some forced movement when they save. That just doesn’t get my engine started.

Summon Thought Champion: PsP. This large summon turns you into a lazylord by spending your standard action to use one of your allies’ at-wills. Unfortunately you don't get added benefits like curse damage or cold vulnerability, so they won't be quite as effective as they are for your allies, making this a trap choice.

Cha-Psions take Intellect Fortress, Wis-Psions go for Transport Self. If you're trained in Dungeoneering, also consider Stay Back. Otherwise you have access to powers that increase your mobility or let you hide easily, and skill powers that can shore up all sorts of shortcomings.

Intellect Fortress: PHB3. This is a good reason to be a Cha-Psion. Having 18 Cha makes this the equivalent of the acclaimed Wizard power Shield, but for all your defenses. Once your Cha rises further, this simply lets you negate any attack that's not a crit once per fight. Take this and love it.

Transport Self: PHB3. This gives Wis-Psions a Fey Step, which is a very underrated power. You'll mostly use it to teleport to safety, presumably out of a grab or to higher ground so enemies can’t easily reach you.

Mind Shroud: PsP. Although it slows you, this gives you an effective +5 bonus to all your defenses for a round. Very good to have if you expect to get attacked in melee often. Essential for Stealth builds who can use this to hide in plain sight. Even those who aren't built for Stealth can still try to hide, because hey, free combat advantage!

Telekinetic Lift: PHB3. The rating assumes you use this on a portable platform of some sort (like a shield) to create a glider that you or an ally can use to fly around on for one encounter per day. If you don’t use it that way, the power only has niche and roleplaying purposes.

Borrow Training: PsP. Even if your ability score for the skill sucks, a +5 bonus is huge. Use this to succeed on physical checks like Athletics, Acrobatics and Thievery, or for those skill challenges during combat that require training in a very specific skill.

Dimensional Stowaway: PsP. The power is cool, but a little out of place on a Psion. Your only power that’s really good with this is Transport Self of the same level, and then only if you’re a Wis-Psion. Better if you’re an Eladrin, Shadar-kai, Shardmind or Wilden.

Buoyancy of Thought: PsP. Being knocked prone can be incredibly annoying. But if you’re really concerned about that just take the level 2 Acrobatics utility Agile Recovery or wear Acrobat Boots. Preventing falling damage can come in handy once in a blue moon, but it’s no reason to take this power.

Skill Empowerment: PHB3. As a daily power this is very underwhelming. I guess if you’re concerned about that one very important skill check that seems to come around once every adventure, then you can take this.

Skill powers

Class skills:

Stay Back: DSH. Dungeoneering. With something as simple as a Sunrod (4 gp), you can give all enemies within a 20-square radius a -2 attack penalty for a round. Not bad for a minor action! A Floating Lantern (level 3 common item) makes this even easier, although the radius is "only" 10 squares. Just suspend your disbelieve for a second when you're using a torch to scare off Fire Elementals in bright daylight.

Arcane Mutterings: PHB3. Arcana. If you dumped your Charisma, this gives you an out if you're faced with a sudden social check.

Strategist's Epiphany: PHB3. History. If you don't have another way to boost your initiative, use this for that one combat where you really need to go first.

Non-class skills:

Agily Recovery: PHB3. Acrobatics. This power alone is worth getting training in Acrobatics for. Although not as good on you as it is on melee characters, using your minor action to stand up from prone is super for your action economy.

City Rat: PHB3. Streetwise. If you get training in Streetwise somehow, your score should be very good. Hiding then becomes much easier, giving you a round of reprieve and/or free combat advantage which is kind of hard to come by otherwise.

Failed Diplomacy: DSH. Streetwise. A party-wide +2 power bonus to initiative is nice, but when it comes with free combat advantage during the first round it's certainly worth considering. Don't take this if you have a Warlord with Combat Leader in your party.

Iron Resurgence: DSH. Heal. It's not cheap on the healing surges, but if you want to act as the party's back-up healer, this is an okay way to do it.

Your class powers at this level are pretty bad, so you'll probably look to level 2 or take a skill power like Insightful Warning, Guided Shot or Timely Dodge.

Mental Void: PsP. Like Shield and Intellect Fortress, but only for your Will. Which isn’t bad, because that’s one of the defenses that’s most likely to get attacked if you stay at range. Getting a round of combat advantage out of it against the target is gravy.

Intellect Prism: PsP. This lets you be a Shaper or Dreamwalker for one encounter per day. The fact that the Prism has +4 to all defenses and hp equal to your surge value actually makes it pretty good. When it’s destroyed you’re dazed for turn, but by that time you should be well out of reach of the enemy. Obviously red for Shapers and Dreamwalkers.

Shared Recovery: PsP. Getting 10 free temp HP each fight is certainly good. Too bad the conditions (an ally within 5 regains HP or makes a save) are not the most reliable of circumstances, especially in the first rounds of combat when you’re most likely to need the temps.

Explosive Force: PsP. A free action encounter power that gives you combat advantage is very good in theory, since you have a hard time getting it as a ranged caster. It’s too bad there are so many hoops you need to jump through to obtain it (hit with an unaugmented force power, there must be enemies next to the target). I wouldn’t bother.

Telekinetic Screen: PHB3. Reducing the damage from a critical hit might just save your life. It just shouldn’t come into play more than once per day, and even then it might not be enough to save you.

Steadfast Stanchion: PHB3. Letting you and your party ignore forced movement for as long as you don’t move is pretty nice, but it’s not remotely worth a standard action.

Mind Shadow: PHB3. So let me get this straight: you can’t use this to sneak past some guards because you’ll be their nearest enemy, and the invisibility fades the moment you hit with an attack? And this is a daily power? Do yourself a favor and skip this.

Skill powers

Class skills:

Insightful Warning: PHB3. Arcana. You not only prevent yourself from getting hit by an annoying burst or blast, with a little luck you can do the same for one or two allies. Preventing hits is a crucial skill to have in your arsenal as a fragile controller.

Guided Shot: PHB3. Perception. If your ally misses an important attack by one or two points, use this to hopefully make it a hit. Very nice if you want to minor in leading.

Warp in the Weave: DR385. Arcana. Although outright preventing a hit is awesome, it’s not like you have healing surges to spare. Use it to avoid a dragon’s breath attack, not the first area attack that comes your way.

Prescient Maneuver: PHB3. Insight. Chances are that an enemies have to cover quite a lot of ground to attack you. Use this to stay just out of their reach.

Everybody Move: PHB3. Intimidate. An emergency button in case you’re surrounded. It automatically hits, so it can get you out of some sticky situations. Better for Shapers and Dreamwalkers who can use it to somewhat rearrange the battlefield.

Non-class skills:

Timely Dodge: DSH. Acrobatics. Cancelling any melee attack made against you once per encounter is extremely good for a fragile controller like you. If you’re trained in Acrobatics, don’t look any further.

Shrouding Gloom: PHB3. Stealth. Builds that want to hide can make good use out of this to prevent attacks and get free combat advantage. Not for everyone, but good for those that can use it.

Natural Terrain Understanding: DR385. Nature. A small Reorient the Axis, coupled with an AC bonus once per encounter is a very decent use of your minor action. For those of you who want some leader capabilities.

Swift Recovery: PHB3. Heal. Although this requires you to get into melee, raising an unconscious ally as a minor action can be critical to the outcome of a battle. If combats go awry, you’ll be glad to have it. Better for Shapers and Dreamwalkers who can just send their conjuration in to do the job for them.be critical to the outcome of a battle. If combats go awry, you’ll be glad to have it. Better for Shapers and Dreamwalkers who can just send their conjuration in to do the job for them.

Plenty of decent options at this level, but nothing that’s head and shoulders above the rest. Dimensional Shortcut is very close to skyblue though, and Trace Teleport is worth considering if you have an Eladrin or other teleporter in your party.

Dimensional Shortcut: PsP. Wow, Reorient the Axis and then some! Laugh as you teleport your party right next to the badguy who was hiding behind his wall of minions. Cheer as you ace the skill challenge where you must climb a tower or a cliff. Feel relieved when you get your party to safety in a fight gone bad. A truly awesome power that is only held back by the fact that it’s a daily.

Mind over Flesh: PHB3. A free saving throw against the most annoying conditions in the game is always welcome. Even better is that the conditions themselves don’t have to be save ends. In combination with Superior Will (which you should have by now), you’ll never be dazed or stunned again.

Force Barricade: PsP. A bit small and fragile for a wall, but it’s still a wall. It’s also the only wall you’re ever going to get as a Psion, so take that into account when considering this power.

Sky Hook: PHB3. Turns you into a Pixie for one encounter per day. Crucial difference is that the altitude limit puts you just out of reach of most medium creatures. Good if you don’t yet have a way to fly.

Intellect Leech: PHB3. A Stirring Shout just for you and for allies who do psychic damage. The amount of temporary hit points you can harvest with this is pretty good if you’re a Cha-Psion, and might save you a healing surge or two.

Trace Teleport: PsP. Without teleporters in your party, this is only occasionally useful when an enemy tries to circumvent the defender by teleporting adjacent to you. With other teleporters in your party however, this becomes a virtually free move action every encounter. Take this power accordingly.

Force Bubble: PHB3. This can come in handy occasionally when it’s clear on turn 1 that you’re facing elemental-themed artillery. As you can imagine, that scenario is rare enough that taking this power is optimistic at best.

Energy Mitigation: PsP. While not a bad power, this is a little overshadowed by the level 6 power Warp in the Weave. This doesn't cost you a surge though.

Skill powers

Class skills:

Prescient Defense: PHB3. Insight. Preventing hits is certainly worth a utility power. Although it won’t prevent a lot of them, it’ll protect you once every one or two encounters.

Stall Tactics: PHB3. Bluff. This essentially increases the party’s initiative by 10, except against enemies that you can’t see. Very good to end a fight before it can properly begin.

Snap Out of It: PHB3. Intimidate. Having a dazed defender or a dominated striker can make combats turn ugly quick. If your leader isn’t the type who deals in saving throws, you can help out by taking this. Better for Shapers and Dreamwalkers who can let their conjuration step into melee for them.

Non-class skills:

Navigate Crowds: PHB3. Streetwise. Shifting your speed once per encounter is a very handy trick to have in your back pocket. While no teleport, it does allow you to get out of some pretty sticky situations.

Again lots of cool powers here, but you need a very good reason not to be trained in Insight and just take Insightful Riposte at this level.

Precognitive Step: PHB3. A reroll, or preroll in this case, is invaluable for any character, even it’s only once per day. The fact that you can still use it if you make a crappy roll makes this awesome. Insightful Riposte is a lot better though.

Mind Blank: PsP. Making yourself and your allies invisible to all enemies in a close burst 3 is pretty sweet, but unfortunately that means you’ve got to enter melee. Not so for the Shapers and Dreamwalkers among you, though. Place this on your conjuration, move it next to your melee allies and watch your DM groan in frustration. Just keep in mind that the zone is probably gone when your conjuration gets hit.

Psychic Chirurgery: PHB3. As a free action, this is very flexible. Good to use on yourself at the start of your turn to ignore any condition for two turns, or on an ally who was at the wrong at end of a stun or just a lot of ongoing damage. Even better for Shapers and Dreamwalkers who, once again, can send their conjuration into battle to do the dirty work for them.

Dream Traveler: PsP. You become a ghost for one encounter, but you’re weakened. Fortunately, that’s a fine trade for a fragile controller, who is there for status effects first and damage second.

Subjective Reality: PsP. Ignoring anything but blocking terrain once per encounter is one of those abilities that’s deceptively powerful. From water and bushes to lightning pillars and lava-pits, this will get you through them without any trouble. Don’t forget to wave to your allies and enemies who are left on the other side.

Kinetic Grasp: PsP. As an encounter power this is pretty sweet. Forced movement and prone are common enough that you’ll get a use out of this in most encounters. Fits better on a leader than on a controller, but that’s your secondary role anyway.

Freedom of Movement: PHB3. Party is slowed, trapped in a quagmire or ambushed by a bunch of Gelatinous Cubes? Not a problem once you use this power. If your wisdom is good you can also use this to get your partymembers to where they’re supposed to be. Another leader power, and a bit of a situational one, but when this is useful you’ll be superglad you have it.

Telekinetic Boost: PHB3. It’s a fun power for Wis-Psions, but the range on it just sucks. If your allies are within 5 squares of you, there aren’t a lot of places you can slide them to that they couldn’t have reached themselves. Although using this as a springboard can both be useful and hilarious in the right circumstances.

Skill powers

Class skills:

Insightful Riposte: PHB3. Insight. You couldn’t ask for a better utility power. Turning one miss into a hit each encounter is enough reason for any character, but especially a controller, to train Insight.

Indomitable Ally: PHB3. Diplomacy. It won’t be often that you’ll have an ally within 5 squares dropping to zero HP unless you are ambushed. Still a pretty good power to keep your allies going for another turn.

Elemental Countermeasures: PHB3. Arcana. Your Arcana should be pretty good by now, so why not use it to become more resistant to elemental damage?

Non-class skills:

Diehard: PHB3. Endurance. Super risky because most monsters won’t hold back on a PC that’s still standing, but this will keep you going long enough for the leader to bring you back up to positive numbers. Use at your own peril.

Nightshade Draught: DR385. Nature. Like Diehard, this also keeps you going if you drop below zero but at the cost of a few death saves. Use at your own peril.

Wis-Psions look no further than Forceful Repositioning. The rest has a nice choice of leader-like powers that protect you and your party.

Forceful Repositioning: PsP. If there’s one reason to choose Wisdom over Charisma, this is it. Giving yourself and your party a free move action each encounter is just awesome. Using this on turn 1 ensures everyone gets into position, so they can use their move action as another minor for that nova sequence.

Warding Shield: PHB3. If your Wisdom is high enough, you can really ruin a dragon’s day with this. This, combined with Warp in the Weave and Energy Mitigation, should properly protect you from blasts and bursts.

Summon Fleeting Thoughts: PsP. A leader-like summon that protects you and three allies and lets all of you fly through the air on your move action. There’s just a lot of utility in this, even if it’s only for one encounter per day.

Interdicting Thoughts: PsP. Entering melee is dangerous, but might be worth it for this. Skyblue for Shapers and Dreamwalkers who just center this on their conjuration every encounter and stay safely in the back themselves.

Through the Walls: PHB3. Giving your party phasing once per day can just trivialize some encounters, both in and out of combat. Walking through walls certainly won’t be useful in every encounter, but when it works it’ll be sweet.

Mind over Earth: PHB3. Flight for one encounter per day is nice, but you’re better off just investing in a pair of Zephyr Boots at this point.

Rejuvenate the Mind: PHB3. You shouldn’t use your second wind much as a controller, and getting 2 power points back once per day is not very impressive at this point.

1. Accuracy. Hitting is king in terms of character optimization. Most of your powers literally do nothing when you miss, which in turn means enemies are free to rampage across the map to attack you and your allies. You don’t want that to happen, at all, so boosting your accuracy is something you should do whenever possible.
Must-haves: Expertise (Orb or Staff being most common), Superior Implement Training: Accurate, multiclass Druid + Acolyte Power for Serpent's Cunning.

2. Initiative. Going first is of paramount importance to a controller. Most strikers won’t kill monsters in one turn, and leader buffs are good but not critical in the first turn of the battle. Control is a different animal: if you manage to immobilize melee monsters before they’ve taken a turn, they can’t reach the party, won’t do damage and thus skip a turn. Next turn, you can do it again, keeping them ‘stunlocked’. But that won’t be as effective if the enemies are already in the party’s midst.
On top of that, with high initiative you will also be able to fire off a power and then run for cover. You are fragile (see next point), so you need to GTFO before team monster has a chance to reach you. That’s why initiative is so important to you.
Must-haves: Improved Initiative (retrain to Superior in Epic), Danger Sense, Battlewise for Wis-Psions, Battle Intuition (Deva), Imperious Majesty (Tiefling).

3. Defenses. You’re fragile, make no mistake about that. Although your primary stat feeds into your AC and most of your powers are ranged, if team monster ambushes your party or just wins initiative, you could easily be down or even dead in one round of focused fire. Upgrading your defenses helps to prevent this.
Must-haves: Unarmored Agility or Armor Proficiency: Leather, Improved Defenses (becomes mandatory at paragon), Superior Will.

4. Versatility/effects. There are several feats that increase the control aspects of your powers, like adding forced movement or attack penalties to every hit. Everything that makes you a better controller is worth investing in. Not every Psion will qualify for every feat, but take ‘em if you can use ‘em.
Must-haves: Psychic Lock, Skill Power, Anchoring Push (Telekinetic Psions), Royal Command of Asmodeus (Tieflings), Secrets of Belial (Tiefling)

5. Damage. Face it, you’ll never do a lot of damage. But since every party member has to contribute to taking down the enemy, it won’t hurt to at least put a little effort into increasing your damage output.
Must-haves: none, but Implement Focus is decent. If you can get and use them, you can instead take Psychic Focus, Jagged Force, Silvery Glow or Battle Psion. If you specialize in a certain damage type like psychic, instead of taking a Superior Accurate Implement you can take one that's energized and still has the attack bonus against a common defense. Examples: Crystal Orb, Inexorable Ki Focus.

Autohypnosis: PsP. Gaining an additional surge is a solid benefit for you, but if you want more surges you can take Durable for double the benefit. Using Arcana for Endurance checks is nice, but not worth the feat. I would only take this if you regularly have to make Endurance checks (Dark Sun) or if you already have Durable and still need more healing surges.

Beguiling Torment: PsP. Daze + slide is a powerful combination to prevent enemies from attacking or charging (just slide them 1 square away from the defender). But paying 1 power point and a feat for it? What makes matters even worse is that most of your at-will powers only daze if you augment them, which ensures you’ll run out of power points very quickly. Maybe at late paragon or epic if you have power points to spare.

Bloodied Concentration: PsP. First things first: with your paltry HP and number of surges, you should always avoid getting bloodied. Even then, only getting a bonus to augmented at-will powers is not worth a feat at all. Maybe if you’re a Dragonborn to stack with Dragonborn Fury, but that’s mostly just a bad niche.

Controlling Advantage: PHB3. Stuff that increases your forced movement can get pretty powerful pretty quickly. Combine this with a superior Forceful implement for example, and you can see how powers like Dread Spiral become very good even when unaugmented. The hard part is getting the needed combat advantage. Distract, Vicious Advantage and Distant Advantage can help you out here.

Discipline Adept: PHB3. Depends on your Discipline Focus of course, but especially Telekineticists and Shapers benefit from this. This becomes mandatory for Telekineticists when they’re going for Anchoring Push at paragon. Shapers who take the Dreamwalker paragon path can safely give retrain this.

Diverse Focus (Elan Bloodline): PsP. Gaining access to Shaped Consciousness or Forceful Push is nice, but as a daily power it’s hardly worth the cost of a feat. Not to mention that you also need to have the Elan Heritage feat to even qualify for this.

Double Scrutiny: PsP. You like an untyped +3 bonus to two class skills, but paying a feat for them is pretty harsh. Still, the bonus is quite substantial, so it’s not out of the question if you want to be a living trap- and lie-detector.

Exchange Power: PHB3. Only an option if you have a psionic ally in your party. But even then the situation where you want to give a power point away is rare enough that you’d hardly use the power if you got it for free. You certainly don’t want to spend a feat on it.

Mindlink: PsP. Take this if you face a lot of invisible enemies. Otherwise, the effect is just too weak to be worth a feat.

Orbiting Object: PHB3. There are plenty of situations where having an extra hand can be useful. Saving yourself a minor action to draw a consumable or a back-up implement can become quite valuable at that point in your career when you have more stuff than you know what to do with.

Power Cascade: PsP. The damage is far too low and the conditions too uncommon to waste a feat on this.

Precise Mind: PHB3. I can imagine taking this feat before level 7, when you have only 2-4 power points, to increase your accuracy somewhat. But even then the duration is too short, and the effect too overshadowed by other feats, to consider spending one of your precious feat slots on it.

Psionic Initiative: PsP. If you always have one power point to spare, you could take this over Improved Initiative. A +6 bonus to initiative is just ridiculous, and will most certainly help you assert early control over the battlefield. Don’t forget to retrain this in Epic to Superior Initiative.

Psionic Skill: PsP. Not bad for a Sage of Ages if you want to make sure you get the full benefit of Trick of Knowledge, or Stealth builds who really want to succeed at becoming hidden.

Psionic Toughness: PsP. Getting additional HP when you use your second wind is a nice benefit, but not enough to top Toughness. Which already is a questionable pick.

Vicious Intrusion: PsP. Not worth it at heroic tier because you can only target one creature, and not worth it at higher tiers because 3 extra damage won’t make a dent by then.

Vision of Madness (Foulborn Bloodline): PsP. If you attack 2-3 targets per turn in bursts and blasts, the chance you’ll score a critical hit at least once per fight is decent. Tacking a daze or a little extra damage onto the crit is not bad, but the fact that you can’t control who gets it makes this very niche. Needing Foulborn Heritage as a prerequisite makes things even worse.

Aberrant Mark of Madness: EPG. Not for every Psion, but if you specialize in attacks versus Will and pick multitarget dailies (as you should), this one feat could mean a +2 to all your attacks for as many combats as you have daily attack powers. Illegal for LFR.

Armor Proficiency: Leather. Take either this or Unarmored Agility to boost your AC to an appropriate level. Which one you’ll pick probably depends on the armor you find. Cloth has a slight lead because masterwork armors (Githweave etc.) boost your Will instead of your Reflex. Attacks against Will usually have more annoying effects, and your Ref is already tied to your main stat anyway.

Battlewise: HoFK. The rating assumes Wisdom is your secondary stat. Initiative is very important for a controller, and since Dexterity is one of your dump stats this feat is a no-brainer. Deva take Battle Intuition instead.

Beguiling Enchantment: PHB3. This rating assumes you use Betrayal or Sudden Control often. Those two powers don’t work with Psychic Lock, but you can at least use them to make yourself harder to hit.

Coordinated Explosion: PHB2. This doesn’t work well since the majority of your powers are unfriendly, but there are some good friendly ones (Dimensional Scramble, Kinetic Burst, Shield Crack and Psionic Veil for example). If you find yourself regularly using these powers, pick up this feat for some added accuracy.

Disciple of Inspiration: HoFL, HoFK. Since all you do is use at-will powers, you will find yourself missing with them sometimes. Getting an accuracy boost for two turns is a nice consolation price.

Distant Advantage: PHB2, HoFK. Combat advantage is harder for you to come by than for your allies in melee. This will help you out. Be aware that it’s useless if you’re built to prevent enemies from approaching your allies.

Durable: PHB, HoFL, HoFK. Boring, but it might be necessary if you regularly find yourself a surge or two short during your adventures. Invest in defensive feats first, but don't hesitate to take this if you still need the extra durability.

Elemental Companion: HoEC. You take this for the Storm Talon companion, but there are some hoops you need to jump through to make it work. First, you must have already taken the Born of the Elements feat. Second, you must be using mostly lightning and thunder attacks (Static Mote, Thunder Tether and Shield Crack are all decent to good powers, or multiclass Swordmage to use a Lightning Weapon as your implement to make all your attacks do lightning damage). Third, your defenses must be up to snuff, otherwise enemies just murder the Storm Talon. But if you meet all these requirements, you get a +2 attack bonus against every enemy adjacent to your companion, which is certainly worth the trouble. Works well with Mark of Storm too.

Expertise. Take one of these feats for a good to huge bonus to your accuracy. Which one you want depends on your build, but Staff is best for most Psions.

Spoiler:

Fey Cantrip: HotF. Doesn’t do much by itself, but gives you access to a conjuration (Mage Hand) for easy combat advantage with Tome Expertise, and lets Stealth builds use Chameleon’s Mask to substitute Stealth with Arcana once per encounter.

Great Fortitude: PHB, HoFL, HoFK. You should automatically qualify for both Superior Reflexes and Will, but probably not for Fortitude. If you already took the other two feats, no reason not to take this one. Otherwise, stick with Improved Defenses.

Hafted Defense: PHB3. Getting a +1 shield bonus to AC and Ref is pretty good for staff users. It also opens up Rhythm Blade Wrist Razors for another +1 bonus to both defenses.

Impending Victory: PHB3. Additional accuracy is always good, too bad about the bloodied clause though. Once creatures become bloodied, controlling them becomes less important than just killing them. The latter is not what you’re good at. Still, an untyped accuracy boost for most of your powers is not something you should skip lightly.

Implement Focus: HoFL, HoFK. At some point you’ll want to invest in a damage bonus. This is the most vanilla one, but take Psychic Focus, Jagged Force, Silvery Glow, Battle Psion or Superior Implement training instead if you qualify.

Improved Defenses: HoFL, HoFK. You could postpone this until paragon if you really want some other feats first, but from that point on there’s no excuse for not grabbing a large feat bonus to three different defenses.

Improved Initiative: PHB, HoFL, HoFK. Like I said in the intro, going first is really important for a controller like you. You need to prioritize this feat or risk being ineffective in your role.

Mark of Storm: EPG. You can use this to add forced movement to Static Mote, Thunder Tether, Shield Crack and some dailies, which is pretty good. It helps that all three at-will powers are decent to good. If you find a way to use a Lightning Weapon as an implement (multiclass Swordmage is easiest), you can add the forced movement to all your powers. Lastly, combining all this with a Storm Talon Elemental Companion gives you a huge attack bonus. Illegal for LFR.

Resilient Focus: HoFL, HoFK. A +2 feat bonus to all your saving throws is never bad. Think about this right after you’ve paid all your feat taxes.

Silvery Glow: DR386. A substantial damage bonus to all your cold and radiant powers. One problem: you have only one at-will power that does radiant damage, and none that do cold. But multiclassing to Swordmage and wielding a Frost/Radiant weapon gets around this. Requires worshipping Sehanine, which means you can't take the next feat.

Skill Power: PHB3. There are a lot of good skill powers you can take, especially if you pick up some non-class skills like Arcobatics or Streetwise through your multiclass or background. Pick this up when you have room, you won't regret adding another utility power to your arsenal.

Speaker of Hestavar: DR387. If you specialize in forced movement to get enemies next to your allies, this feat gives them free combat advantage against your targets for a round. If you can repeat this round after round with powers like Dread Spiral and Psychic Anomaly, this feat can become a cornerstone to your build. You have to worship Erathis for it, but he seems like a good guy for a Psion to say the occasional prayer to.

Staff Fighting: DR368. Like Hafted Defense, this gives staff users another +1 to AC in exchange for a feat, untyped this time.

Superior Implement Training: PHB3. You will mostly just want to train for an Accurate implement, but there’s some stuff like a Crystal or Petrified Orb that’s worth considering.

Superior Fortitude/Reflexes/Will: HoFL, HoFK. You probably won’t qualify for Fortitude, so let that one slide. Reflexes is nice because your first turn in an encounter is often the most important one, so getting combat advantage against everything is good. Will is where it’s at though. Rolling a save against two of the worst conditions in the game can mean the difference between a wasted turn and an awesome one.

Terrain Advantage: HoFK. If you find yourself regularly creating difficult terrain with powers like Kinetic Wave, Interdicting Thoughts and Phantom Burden, you might as well get combat advantage out of it.

Unarmored Agility: PHB3. Take either this or Armor Proficiency: Leather to boost your AC to an appropriate level. Which one you’ll pick probably depends on the armor you find. Cloth has a slight lead because masterwork armors (Githweave etc.) boost your Will instead of your Reflex. Attacks against Will usually have more annoying effects, and your Ref is already tied to your main stat anyway.

Vicious Advantage: PHB3. You get good slowing powers from level 1 on, so it’s very worthwhile to invest in this to get easy combat advantage. One of the easiest ways for a Psion to get it consistently too. Combine it with World Serpent's Grasp to give your melee allies combat advantage as well.

Vistani Heritage: DR380. A great minor action control power in exchange for a feat, and it opens up Vistani Foresight in epic.

World Serpent’s Grasp: HoFK. If you specialize in slow and immobilize, this will serve you well in both assisting your melee allies and keeping enemies off you. You have enough good slowing and proning bursts that the added control from this is really worth considering.

See the multiclass section of the handbook.

Anchoring Push: PsP. This turns Forceful Push from nice forced movement into hard action denial. As a free action, no less! Use it at the start of a monster’s turn to be certain it can’t reach you or your allies. Discipline Adept becomes mandatory if you take this.

Battle Psion: PsP. This requires some careful power choices and reckless power point expenditure to be better than Implement Focus, but it’s almost never worse.

Body and Mind: PsP. An untyped bonus to all your defenses is nothing to sneeze at, and not unworthy of a feat. It also increases your conjuration’s defenses so you hopefully keep the defense bonus a little longer.

Body Fuel (Elan Bloodline): PsP. A free power point with your second wind is a nice bonus. It’s not a lot, but it might just be the difference between an augment 1 and an augment 4. Too bad it requires the Elan Heritage feat. Better for Kalashtar and Shardminds who can combine it with their paragon racial feat for another power point when they second wind, and of course for dwarves.

Confusing Distraction: PsP. Denying opportunity attacks is a big increase in Distract’s versatility. As a minor action auto-hit effect against two or three targets, this feat can save your party a lot of damage.

Corrosive Thoughts: PsP. Inflicting a very small psychic vulnerability when an enemy fails a save against your Psion powers is simply not worth a feat, especially because the only save ends effects you have are on daily powers.

Critical Reserve: PHB3. The good thing is, you have lots of area burst powers so scoring a critical hit is easier for you than for others. But only triggering once per encounter when you use an unaugmented power (which probably means you’re out of power points) kills this. A little more interesting once you reach epic and take Psion Implement Expertise, or have the Life Singer or Divine Oracle paragon path.

Desperate Renewal: PHB3. Regaining power points is always a good thing. However, if you have to spend a standard action while bloodied to do so, the cost becomes very steep. Only consider this if you’re a dwarf.

Dominating Mind: PHB3. Save penalties are good, especially when they are for conditions like dominate and stun. If you pick your dailies right, this feat makes them that much more powerful.

Empty Vessel: PsP. A decent attack and defense bonus for a round once per encounter is nice to have, but it'll be towards the end of the fight that you'll get it. Not the best timing, so I can't really recommend it.

Power Surge: PsP. Although Psions don’t have a lot of amazing daily powers, most are still worth more than 2-4-6 power points. You should only take this if you’ve optimized around one of your augmented paragon or epic at-will powers, like Brilliant Thought, Forced Opportunity or Sudden Control. Then it becomes a legitimate option to exchange one of your dailies for more power points.

Predictive Defense: PHB3. This is more at home on an Ardent or a Battlemind than on a Psion, but if you find yourself in melee a lot this can really save your bacon.

Prescient Dodge: PsP. This is more of a defender feat than a controller feat. You don’t want to spend your time using unaugmented powers just so you can get a defense bonus. Only take this if you optimize around unaugmented at-wills for some reason. Maybe you’re a hybrid?

Psionic Rush: PsP. Power point economy is nice. This gets better when you have more action points to spend, for example as a Sidhe Lord or with Vistani Foresight.

Psionic Staff Focus: PsP. Completely unnecessary thanks to Staff Expertise.

Psychic Wail: PsP. Free combat advantage when you kill something with psychic damage is not something that you need to spend a feat on.

Puppeteer: PsP. I can’t imagine a scenario where it’s profitable (read: worth a feat) to slide a target 1 square if they miss a save against one of your Psion attack powers. If you do, kudos. If not, then skip this feat accordingly.

Targeting Force: PHB3. If you really, really love Force Grasp, this is a pretty good way to increase your accuracy. This also works well with the minor action attacks of Living Missile and Living Barrage.

Threefold Fortitude/Reflex/Will: PsP. Just take Improved Defenses or Great Fortitude/Superior Reflex/Superior Will.

Danger Sense: PHB. If you want more initiative optimization besides Improved Initiative, this is the go-to feat. Rolling twice for initiative really helps even out the variance of that single important roll.

Inescapable Force: PHB. You have a lot of force powers in your arsenal, and no enemy is as annoying as an insubstantial one. Additionally, there’s nothing like the strikers asking you to take out the enemies.

Psychic Lock: PHB. This is the feat most of you have been waiting for since level 1. Applying a -2 attack penalty to every psychic attack you make, on top of other control effects, is awesome. Even more fun when you combine this with Dishearten. More fun you, that is. Not for your DM, because his monsters won’t be hitting anything ever again. If you're not into psychic attacks, an Orb of Psychic Conversion quickly takes care of that. As close to gold as a non-expertise feat is going to get.

Reserve Maneuver: PHB2. While this is a staple for most classes who dislike their paragon path encounter power, remember that you don’t have any class encounter powers to swap for, making this feat useless.

Solid Sound: PHB. From level 13 on you'll be using Thunder Tether regularly, and you have enough force powers to make this trigger every turn. Pay attention to what defenses are attacked, and you’ll make it a lot harder for enemies to hit you.

Resounding Thunder: PHB. If you manage to add the thunder keyword to your bursts and blasts (Malec-Keth Jannisary, Rod of the Dragonborn), bigger Disheartens and dailies can be yours! Also increases the size of your Thunder Tether cage.

Aggressive Construction: PsP. Dealing a few extra damage when you use a daily summon power is not really worth a feat. Better with Mind Weirds if you cluster them around one enemy or use multiple summon powers during a turn.

Boundless Enthusiasm: PsP. Scoring a critical hit is not the most reliable of triggers, but the benefit is big enough to consider this. Take Psion Implement Expertise first, and use as many burst and blast powers as you can to increase the odds of getting the power points back. Even better with the Resurgent Wilder, Life Singer or Divine Oracle paragon path.

Far Realm’s Blessing (Foulborn Bloodline): PsP. Becoming bloodied shouldn’t be a goal for you in a given encounter, but getting back a power point is a decent incentive. Too bad a single power point is much less impressive at this stage. Needing the Foulborn Heritage feat is also a steep rerequisite.

Gift of the Eternal (Elan Bloodline): PsP. Although regaining one power point isn’t much of a benefit at this point, you won’t have to jump through hoops to get it. Requiring Elan Heritage for it reduces the rating on this to black.

Lingering Force: PsP. An untyped defense bonus for using your Telekinesis powers is a nice benefit. This feat becomes better if you took Discipline Adept. And since you’re a Telekineticist, you have probably already taken it for Anchoring Push.

Psionic Discorporation (Elan Bloodline): PsP. Being insubstantial while below 0 hp is not worth a feat, especially since most epic destinies have some sort of anti-death power. The attack bonus while no longer dying shouldn’t come into play if you’re careful. And it also requires the useless Elan Heritage feat. But what about Revenants, you say? Well, they take Ghostly Vitality anyway, so they don’t need this feat.

Psion Implement Expertise: PsP. Scoring critical hits is fun, but if you’re not built for damage you don’t get anything special out of it. If you benefit from it though, for example with one of the next two feats or Boundless Enthusiasm, it becomes better.

Psychic Bastion: PHB3. Scoring a critical hit with a psionic psychic power is not the most reliable of triggers, but the benefit is big enough to consider this. Take Psion Implement Expertise first, and use as many burst and blast powers as you can to increase the odds of getting the bonus. Even better with the Resurgent Wilder, Life Singer or Divine Oracle paragon path.

Resilient Shield: PHB3. Scoring a critical hit with a psionic force power is not the most reliable of triggers, but the benefit is big enough to consider this. Take Psion Implement Expertise first, and use as many burst and blast powers as you can to increase the odds of getting the bonus. Even better with the Resurgent Wilder paragon path.

Stalk the Senseless: PsP. Dazing and stunning creatures is now a part of your arsenal of at-wills, so this acutally works on a regular basis. However, being invisible to a stunned creature is about as useful as a pair of glasses on a Beholder. Being invisible from dazed creatures is a little more useful, but I don’t think it’s really worth a feat.

Epic Fortitude/Reflex/Will: PHB2. Still scared about getting hit? The untyped defense bonuses these feats offer should definitely put an end to that. Take Fortitude to patch up your weakest defense, and consider the other two to become truly unhittable.

Fey Shift: HoF. Teleport 2 as an additional movement mode is pretty awesome, even if it requires the Fey Bond feat or a fey origin. If you also have Staff Expertise, you won’t provoke opportunity attacks ever again.

Superior Initiative: PHB3. Retrain Improved Initiative to this as soon as you can. That is all.

Vistani Foresight: DR380, Vistani Bloodline. An additional action point and an untyped initiative bonus? Where do I sign?

Noble Adept: DSCS. The absolute best theme for you. You get an extra power point, an awesome encounter power, some nice utilities and even a couple of daily powers that are competitive with your own (although that says more about the general quality of Psion dailies than the ones of this theme). Illegal for LFR though, since it’s a Dark Sun theme.

Escaped Thrall: DSH. Although this grants a small power bonus to Will, Noble Adept offers much, much more. It has one advantage over Noble Adept though: the ability for Dreamwalkers to conjure their dream form as a minor action with the level 2 utility power. So take this if you're a Dreamwalker or otherwise can't take Noble Adept for some reason (like LFR).

Bloodsworn: DSH. An encounter reroll for at-will powers while you’re bloodied and a power bonus to initiative at level 10 make this a fine theme for Psions.

Cipher: DR414. A theme that gives you a power bonus to initiative as its starting feature is very nice for the lower levels, where your initiative is still crap. The level 5 and 10 features are decent, as are the powers, but when your initiative is high enough this quickly drops in quality and becomes retraining material.

Fey Beast Tamer: HoF. The extra body can protect you from charging foes, but the real value of this theme is the level 5 feature that grants you combat advantage against all targets adjacent to your companion. As for what companion to take, the Young Owlbear is head and shoulders above the rest because the aura actually works for you too.

Halaster’s Clone: DR409. The movement powers this theme offers can help you and your party get into position quickly. If you’re optimizing around initiative, the huge power bonus at level 10 clinches it.

Harper: NCS. Adding 1d6 to one attack roll each combat is pretty good, as is rerolling a missed saving throw.

Order Adept: DR399. The encounter power is pretty bleh, but the level 5 and 10 features are sweet. The best Wizard utility powers to pick are Shield, Moonstride and Mystical Debris for easy combat advantage with the Terrain Advantage feat. Don't take them over Intellect Fortress though if you're a Cha-Psion. Rather wait until level 6 to select the utility power, since that level offers very little for you.

Underdark Outcast: DSH. Since you’ll probably stand far from your allies in melee, you can easily meet the requirement for the encounter power. That means a +2 bonus to attacks and defenses for a full two turns for a minor action, which is awesome. The level 10 utility power is also a very good defensive interrupt against close and area attacks.

Beguiler: DR420. Having a minor action slide 3 at your disposal is easily underrated. A timely slide can put another target in your area bursts, for example. The level 10 utility power is a nice defense one, and getting a bonus to Arcana checks is always good.

Bregan D’aerthe Spy: NCS, Drow only. The levitation power gets you out of the reach of most foes during heroic, and not granting a +2 to enemy attack rolls while being flanked can mean the difference between life and death sometimes.

Devil’s Pawn: NCS. Giving everything in a close burst 2 a penalty to attacks and defenses is risky unless you’re a Shaper or Dreamwalker. In that case you just let your conjuration move into melee and burst into flame for you.

Infernal Slave: BoVD. The encounter power is decent for the large slide it tacks onto your attack. Especially good if you’ve optimized around the Cerulean Cage at-will power for a lot of zone autodamage. Illegal for LFR.

Knight Hospitaler: DR399. If you want to help keep your teammates on their feet, Shield of Devotion goes a long way. Either your Wisdom or Charisma will be pretty high, so you restore a decent amount of hit points. It also gives you something to do with your immediate action.

Ooze Master: DR413, Drow only. You take this for the minor action area burst 1 slow attack. At level 10, it even makes the targets of this and Ectoplasmic Servant grant combat advantage.

Scholar: DR399. As a Int/Wis class your knowledge skills should be up to snuff, so you should be able to use Use Vulnerability succesfully. Whether you want to is another question, though. The defense and damage bonus is nice, but I always get extremely annoyed when combat slows down to a crawl because someone wants to make a knowledge check and the DM starts dwelling on a monster’s preferred food and habitat.

Seeker of Illefarn: DR402, Eladrin, Elves, and Half-elves only. Rerolling any 1’s during combat is a good thing to have in your back pocket. Add to that the U6 for a +2 power bonus to attack rolls, and you have a decent theme.

Sentinel Marshal: DR407. Immobilizing one enemy per fight with any attack you make is great control. Marking them is also good if you make sure they can’t reach you. Just be careful they don't come after you or start firing ranged attacks.

Spellscarred Harbinger: NCS. Becoming invisible as a minor action is a useful thing to have, especially for Gnomes, Wood-Elves and Shades. Otherwise, rerolling a saving throw isn’t a bad alternative.

Trapsmith: DSH. Don’t take this any sooner than level 11. Once you’ve reached this level, you have a good defensive encounter immediate action attack that dazes anyone that moves next to you, thereby ending their turn. It’s not the most accurate attack, but it’s useful enough.

Windlord: HoEC. I’m really tempted to give this a blue rating since I have such great experiences with the encounter power (granted, on a Swordmage). Fly your speed+1, make an attack and slide the target all with one standard action. The level 10 utility power is also nice if you have no other way to change your movement mode.

Wizard’s Apprentice: DR399. Color Orb is pretty good early in your career, and getting a free level 6 common item at level 5 is great. The Noble theme also nets you a free item, but I consider this theme to be much better for Psions. Consider retraining it later in your career though.

Elemental Initiate: HoEC. The encounter power (which actually works for you even when you have an empty hand) and the power bonus to Will are nice, but you take this theme for the ki focus proficiency if you don't want to waste a feat or your multiclass on it. Gnomes, Wood Elves and Shades want a Shadow Master Ki Focus to seriously increase their damage. Other builds that have their hands full with cheap items like Defensive Staff and Rhythm Blade might want to use a ki focus as their main implement because it’s slotless. And lastly, there are a couple of superior ki foci that combine the right attack and damage bonuses: Serene for psychic attacks against Will, and Inexorable for force attacks against Fortitude. Although Crystal Orb carries the same properties as a Serene Ki Focus, the Ki Focus Expertise feat can be better for some psychic builds than Orb Expertise.

Haunted Blade: DR416. I feel weird listing this one, since the theme is centered around using weapon attacks. On the other hand, the level 5 feature of rolling twice for Intimidate is nice, but level 10 is where it's at. From then on, you can use your Charisma instead of your Dexterity for determining initiative. Halaster's Clone is usually better when you want to raise our initiative since the powers on that one actually do something, but there are situations when you don't want a power bonus (when a Warlord already gives it, for example). Then this theme can be nice.

Infernal Prince: DR406. If you’ve taken the Firestarter paragon path, there’s no reason to retrain your theme to this for an additional bonus to your attack rolls. Be aware that the theme is illegal for LFR though.

Sidhe Lord: HoF, fey or Half-elf only. If you multiclass Invoker for the Flame of Hope paragon path, the level 2 utility power of this theme becomes a crucial part of your party’s success, especially if you have a way to spend more than one action point per encounter. Everyone else should avoid this theme.

Wilder: DSCS. If you’re looking for critical hit optimization, Resurgent Wilder is one of the best paragon paths available. Illegal for LFR though.

Auspicious Birth (DR366), Born Under a Bad Sign (DR366), Thay (FRPG). These backgrounds all let you substitute your Intelligence for Constitution to determine your starting hit points. You don’t have a lot of hit points and not much other reason to invest in Constitution, so this can easily raise your hit points by 5-10. For some perspective, that’s the amount the Toughness feat adds.

Dalelands (FRPG), Officer Who Came Out of Retirement (DR366), Trained from Birth for a Specific Prophecy (DR366), Vilhon Wilds (FRPG). Initiative is always important, and these backgrounds give yours a small boost.

Adventurer’s Scion (DR371), Monster Hunter (DR366). If you’re into monster knowledge checks, these two backgrounds will help you out with them.

Dreamwalker: PHB3. This is the go-to paragon path for Psions of almost every stripe. At first glance a conjuration that’s a simulacrum of you might not seem very powerful, but it opens up an unimaginable amount of tactical options. Let’s go over them one by one:

Dream form tactics:

The powers are okay but don’t offer much control, except for the amazing instinctive effect of the daily power that lets you use two at-will powers each turn.

Time Bender: PHB3. This path has a lot of interesting features, just nothing that makes you go WOW! The level 11 feature lets you preroll one d20 roll in combat, so even if you preroll something like a 1 you can use it to replace a hit (or a saving throw!) from an enemy. An attack bonus when you use an action point is always good, as is the free teleport. The extra move action at level 16 can be used to set up some kind of nova sequence where you need multiple minor or move powers, or just to get across the map a little quicker. The powers are all good too, just nothing mindblowing. A nice collection of goodies that together are a very good paragon path for you.

Alienist: PsP. The features are pretty random, but if you’re just looking for some good powers to add to your arsenal, you could do far worse than this. The encounter power shuts down a group of enemies, the utility grants you the rare ability to regain power points, and the daily power is one of the best summons in the Psion’s entire arsenal because it’s the only one with an instinctive attack. Still, a paragon path that makes you not want to use your action point loses rating just for that.

Uncarnate: PHB3. Who you gonna call? Ghostbusters! Uncarnate will make you the undisputed champion of taking out insubstantial creatures. It also gives you a couple of ways to turn insubstantial yourself, which is a good way to dissuade enemies from ever attacking you.

Master Summoner: PsP. Let’s get one thing out of the way first: most Psion summons are bad and you generally shouldn’t take them. If that doesn’t deter you, this path gives your summons some much-needed durability and some additional movement modes. What saves this path from a purple rating is the daily power, which summons a Huge creature with threatening reach 3! It costs a standard action to summon, but believe me, you’ll get your action’s worth of damage out of it. Or everything just stops moving, which is also totally fine by you.

Thrallherd: PsP. This is an evil, evil paragon path. If you’ve always wanted to be a mindflayer, this is the way to do it. Mechanically, Thrallherd grants you what is basically a bad summon that doesn’t go away at the end of a fight. So it’s useful just for putting an extra body on the field, and you get a few free attacks out of it when you use an action point or the daily power. It becomes a little stronger if you use it as a bodyguard, especially after level 16 when it raises your defenses by 2. It’s automatically proficient with whatever weapon you give it, so letting it wield a fullblade, execution axe or mordenkrad increases its usefulness. The thrall has one other very interesting property: it can hold one magic item for you, and can use the item’s powers. This is a small list of useful items to give the thrall:

Items for the thrall:

Cerulean Adept: PHB3. Though not horrible, this path has mediocrity written all over it. The doubled crit rate with augmented powers at level 16 is the only reason you take this path, but only if you’re into critical hit optimization. A little better if you regularly face off against aberrant creatures.

Firestarter: PsP. The idea behind this paragon path (be a Fire Blaster) is fun, but the execution is really poor. The features and powers are almost completely worthless. The only way this paragon path is viable is if you are a Tiefling and regularly use force powers, so you can take the Hellfire Blood feat and the Infernal Prince theme for increased accuracy and Fiery Blood for a damage boost.

Anathema: PsP. The features of this path are absolutely useless, and the powers are not far behind (an attack that makes the target insubstantial, really?!). Avoid.

Mind General: DSCS, Noble Adept theme. If you want to get some more leader capabilities, this could be the paragon path you’re looking for. It lets you move allies around the battlefield and increase their defenses, and the encounter power even lets you grant melee basic attacks. The level 16 feature increases one ally’s NADs and lowers another’s, but you can circumvent this disadvantage by having a Fey Beast for example whose defenses you can decrease. Illegal for LFR because of the prerequisite.

Catalyst: PsP, Ardent. Another leader-like paragon path that lets you grant a lot of free attacks if that’s what you’re looking for. The encounter power combines very nicely with Forced Opportunity to let three allies make two out of turn attacks, and granting an attack when you use an action point is also good. Nothing particularly atttractive beyond level 11 though.

Incandescent Champion: PsP. The only reason you take this paragon path is if one of your partymembers is a Morninglord and you want to join in on the radiant fun. Spending a power point to let all your powers deal 1d6+10 extra damage is sweet. But aside from that and the utility power, the rest of this path is useless.

Divine Oracle: PHB, Cleric. Rolling twice on any attack against Will is one of the craziest features available. In addition to that, your party can’t be surprised anymore, you get Danger Sense for free, and you get an encounter power that will make your Barbarian friend very, very happy.

Malec-Keth Jannisary: MotP, Swordmage. Elemental damage isn’t the Psion’s strong point, but the level 16 feature of this path changes all that. This path allows you to start using Resounding Thunder to increase the size of all your bursts and blasts. You can also become a half-decent blaster this way. The best part is that the extra damage type doesn’t replace any other types your attacks have, so Psychic Lock still works.

Entrancing Mystic: AP, Warlock. If you’re into mind control powers like Betrayal, Sudden Control and dominating dailies, this is the path you’re looking for. The huge saving throw penalty ensures dominated enemies stay dominated, and the attack bonus raises your chances of hitting them in the first place. Powers are meh, but I’ve seen worse.

Flame of Hope: PHB2, Invoker. The action point feature of this path is utterly amazing. Granting all allies an attack bonus equal to your Intelligence modifier should ensure they only miss on a 1 that round. The perfect time for your strikers to pull out all the stops and apply the best status effect: dead. The rest of the path is okay, but not really amazing.

Life Singer: AP, Bard. Like Divine Oracle, you can take this path to increase your accuracy if you attack Will a lot. The features are a bit worse, but the powers are awesome for a controller, provided your Charisma is any good.

Pack Lord: PP, Druid. Chances are you've multiclassed to Druid anyway to powerswap for Serpent's Cunning, so this paragon path is open to you anyway. And if your dailies are summons, this becomes quite a good paragon path. Mostly due to the level 11 feature that gives you a +1 bonus to attacks and defenses if you have a summon out. The encounter power and utility power increase the number of attacks you can make, so that's also decent. The rest of the features and the daily summon power leave much to be desired, but at least they combine nicely with each other. And while you're powerswapping anyway, might as well trade in a Psion daily for another Druid summon to make the path even better. I'd advice a Giant Toad (1) or a Crocodile (9).

Traveler’s Harlequin: DR382, trained in Bluff, more than one class, worships the Traveler. If you want more than one multiclass, this is the way to get it. There are some tricks you can do with this, and it also grants you any level 19 or 20 daily power you qualify for. The rest of the path is also decent enough.

Morninglord: FRPG, any divine, must worship Amaunator. This paragon path is for radiant blaster Psions only. Yes, those exist thanks to the level 13 power Brilliant Thought. The augment 4 is a double attack in itself, so you immediately benefit from the level 16 vulnerability feature. It also sets up the vulnerability for your partymembers nicely. The rest of the path is useful, apart from the Militant Dawn feature because you probably won't have Channel Divinity.

Demiurge: PsP. More Int, more Cha, more action points and nigh-invincibility against save ends effects makes for a nice, clean package that most Psions should consider. No death features, but that’s far from required for an epic destiny to be good.

Mind Lord of the Order: DSCS. Some nice goodies here. +2 Int and Wis at 21, another use of an augment 6 powers at 30, a very interesting but dangerous mechanic that ensures you’ll never skip a turn due to being reduced to zero HP again at 24, and an incredible daily utility at 26 that will make your party leader green with envy. A definite pick if Wisdom is your secondary stat and you’re not a deva.

Master of Moments: PsP. If you have a lot of minor action powers that you need to activate, look no further. Getting a standard, move and minor when you use an action point and having teleport 5 at level 30 is also not a bad deal. And lo and behold, the Freeze in Time utility power finally gives you more control from your epic destiny! Believe it or not, that’s actually rare, even if you only get it as a daily power.

Topaz Crusader: PsP. Don’t like debilitating status effects? Then take this epic destiny and be forever rid of dazed, dominated, immobilized and restrained. You also get awesome defense bonuses and 2 additional power points, which are useful if they put you over the 18 point threshold at level 27 or even 23 so you can use your augment 6 powers three times per encounter. The Cha-bonus is nice, although you’d rather have more Int. Oh, and a daily 11x11 zone that gives all allies regeneration 18 and +2 to attack rolls is nothing to sneeze at either.
If you face aberrants on a daily basis, this epic destiny gets a little more awesome.

Godmind: PHB3. Not a bad destiny by any means, but most features come up just short. The thing that’s most obviously missing is a death feature. Vulnerable 5 psychic is not enough at this level, even if you can deliver it as a minor action. Rolling twice for attack rolls, saving throws and skill checks is awesome, but having to use your second wind in order to get it is not. And 4 extra power points at level 30 are only amazing if it puts you over the 18 point threshold so you can use your augment 6 powers three times per encounter. This destiny becomes better if you can use your second wind as a minor action (dwarf, Herbal Healing utility power) and/or if you have less than 18 power points at level 30 and no good way to get up to 18 over the course of an encounter.
Anyway, what saves this epic destiny is the level 26 utility power that lets you either regain all your power points or all your daily powers! That’s downright insane, especially if you’ve powerswapped with a Wizard power.

Eight Seal: PsP. This is purple because if you’re fighting aberrant creatures on a daily basis, the mileage you’ll get out of this epic destiny is great. If not, then you’re only in it for the Superior Will feature and the utility power, which is basically the ultimate leader power but suffers from costing a standard action to activate.

Cosmic Soul: PsP. Don’t go for this. Although truesight 5, +5 initiative and “ranged: sight” for all your powers is interesting, there are just so many better destinies you could take. Especially the death utility is boring, because it lets others take a turn instead of you. If that was what you wanted, you would’ve played a leader, right?

Avangion: DSCS, arcane class. Though the features of this epic destiny are more leader- and striker-related, they're great nonetheless. A stat boost to your two main stats, a good bonus to death saves and not aging anymore start you off good. Then at 24 you get a fly speed equal to your speed (saves you money for Zephyr Boots) and all your attacks do radiant damage in addition to their normal types. Psychic and radiant is the best possible combo for you if you have/are a Morninglord. The level 26 utility and 30 feature are things your allies will thank you for.

Draconic Incarnation: DR388, arcane class. Two main stat boosts at level 21, two daily arcane powers of your choice at 30, and the ability to turn into a friggin’ dragon! If you want cool while still having a good epic destiny, this is definitely what you should go for.

Planeshaper: DR372. +2 Int is lovely, and the level 24 feature that lets you banish a creature if you crit it gives you a very good reason to take Psion Implement Expertise. The other level 21 feature that lets you use one encounter power twice totally depends on the power of your utilities or paragon path attack power, but can be nice. I’m a little hesitant regarding the utility power that lets you banish yourself and any willing allies as a standard action, since it’s easy for enemies to either beat on the remaining players or ready their attacks on your return. And the level 30 feature is just crazy, I’m really not looking forward to the Planeshaper Wizard player reaching level 30 in my campaign.

Soul of the World: DR385, Deva only. So let me get this straight. You can now take tiefling feats as well as deva feats, get Heroic Effort, get an Int and Wis-bonus, and swap your dailies for Wizard dailies? If you’re a deva, you don’t even look at other epic destinies.

Destined Scion: HoFK. Boring, but effective. Boosts to your two main stats, an attack and saving throw bonus, an anti-death daily power and a nice level 30 daily power. The gold standard if you don’t like to bother with overly complicated epic destinies.

Indomitable Champion: HoFL. The more defense-oriented version of Destined Scion. Where Destined Scion focuses on making your attacks hit, this makes sure you are a hard target to take down. The anti-death power is better since it triggers immediately upon you dropping to zero HP instead of waiting until your initiative rolls around again, but that’s not enough to raise to the highest level.

Archmage: PHB, Wizard only. This assumes you’ve multiclassed into Wizard to get some higher quality daily powers, since this epic destiny is all about using your dailies more often. Wizard dailies are about as good as control powers get, but using Far Realm’s Embrace (23), Thrall (23) or Living Barrage (15) multiple times per day is also something you can look forward to.

Heir to the Empire: PHRT, Tiefling only. Like Royal Command of Asmodeus? Then this is the epic destiny for you! Increasing your main stats is always good, but the level 26 utility is what it's all about. Whenever something dies, you can resurrect it once per encounter as an interrupt to make it serve you until it dies again (or saves against dominate). What could be more fun, I ask you?

Reincarnate Champion: PP, primal class. Not a tiefling? You are now. Go look at the feat list and then pick your jaw up off the floor when you see the possibilities that have now opened up to you. If you’re Wis secondary, Deva isn’t a bad second race to choose at level 24. Otherwise the Human’s Heroic Effort is never bad.
Qualifying for this epic destiny shouldn’t be hard, provided you went with a Druid multiclass for Serpent’s Cunning. Deva take Soul of the World instead.

Sage of Ages: AP, arcane class. The level 24 feature is like being an Avenger, that’s how much it increases your accuracy. And since your Arcana should already be pretty decent, the level 26 utility power makes you pretty invincible, as does the level 30 feature.

Hordemaster: DSCS. The stat bump is nice, but there are more than enough epic destinies that do the same. No, you take this one if you want to be practically unkillable. And the flavor on this one is beyond fun (although maybe a bit impractical for a plane-traveling adventurer). Did you die? Then someone from your entourage will pick up where you left off. And so on, into infinity. At the very least, this allows you to be a lot more reckless in and out of combat. Don't forget to have some fun with the level 30 feature and Blood Fury weapons, by the way.

Thief of Legend: DR388. This is mostly for stealth builds, but it's so much fun I couldn't resist including it in the list for everyone to enjoy. Vanish from sight. Never die. Go anywhere. Steal everything.

Powers: Serpent’s Cunning (Druid), daily attack powers (Wizard), Hide in Plain Sight (Rogue). The level 6 power Serpent's Cunning is by far the best utility power you can have. For the rest of the day, you get a +1 power bonus to all your attack rolls, a +2 power bonus to all Intelligence-based skill checks, and why not, training in a skill of your choice. Unless you’re a tiefling and have access to Secrets of Belial, this costs you two feats (multiclass Druid and Acolyte Power) and a utility power of level 6 or higher, but it’s definitely worth it.
If you want better dailies, you can't go wrong with a powerswap from a Wizard either.
If you're playing a Stealth build, Hide in Plain Sight is just about the best utility power there is.

Paragon paths: Divine Oracle (Cleric), Malec-Keth Jannisary (Swordmage), Entrancing Mystic (Warlock), Flame of Hope (Invoker), Life Singer (Bard). As you can read in the paragon path and epic destiny section, these paths rival psionic paragon paths, and that’s saying something.

Epic destinies: Avangion (arcane), Draconic Incarnation (arcane), Archmage (Wizard), Reincarnate Champion (primal), Sage of Ages (arcane). These epic destinies are all very much worth spending your multiclass on. More on them in the paragon path and epic destiny section.

Additional power points: Awakened Potential, Vampirism (Vampire), Adept Dilettante (Half-Elf). There are three ways to get more power points through multiclassing. Awakened Potential gives you an extra daily power point (two at level 21). Vampirism qualifies you for the Psionic Vampire feat which lets you spend a surge for two power points, but comes at the cost of reducing your surge total to two. Half-Elves can qualify for Psionic Vampire by taking Adept Dilettante as their multiclass, leaving their surges intact.

Weapons as implements (Swordmage). If for some reason you wish to use light/heavy blades as your implement, this is your multiclass. A reason might be that you desperately want to do cold damage, so you take a Frost Blade as your implement. Multiclass Sorcerer gives you the same benefit, but it doesn't bring much else to the table.ring much else to the table.
