Hey everyone,
I'd love to hear about any magic items or artifacts y'all have invented and used in your campaigns. Not only is that interesting to me personally, but I think we'd all benefit creatively from sharing the coolness we've all made up over the years. They don't have to be for 4e, but, it'd be nice...After all, this is a 4e forum.
A player favorite I did a while back was the 'Ancestral weapon'. I stole the idea from that D&D Heroes X-box game.
It works like this: The PCs (if they want to) start with a chosen weapon, or implement, and come up with its story/history. It 'levels' up with them. Gaining cool, and interesting powers, quirks, and abilities as they go. It also gets its obligatory +1's every 4-6 levels as well.
Another fun weapon idea was the Fire Starter (early heroic tier). It's a hand crossbow that just does ongoing 5 fire damage. No '+', or anything. No 1d6, Just ongoing 5 fire damage. And ongoing 10 on a crit. You still get your DEX and proficiency bonus to hit, of course. (Save ends, obviously.)
Light Saber. (mid paragon tier) Because...I love Star Wars, so I just had to.
It's a +3 long sword that targets reflex instead of AC; no matter what AED power, or basic attack, AoO, etc. it's used with. It always does force damage, uses DEX or WIS bonuses to hit and damage, (which ever is higher) and always does maximum damage against inanimate objects. It also adds 3d12 when it crits, and sheds dim light out to 3 squares.
Collapsible pole. (all tiers) This is a simple 'wondrous' utility item. It's a wooden stick...That, on command, can go from 1' long to 10' long. Can't be used as a weapon, per se...But my players have gotten really creative with it.
Dark Lantern. (all tiers) Just like a lantern, but sheds darkness (as per the spell/ability) instead of light. Can only be countered or negated with intentionally cast magical light.
Anyway, I have many more...But, again, I'd love to read your ideas.
