I'm wondering if anyone knows a list of monsters that have dangerous "save or" effects? I'm talking the more dangerous effects, such as: Blinded, deafness, death, petrification, poison (bad poison not just ongoing 5 or 10), etc. I've been considering running a fairly deadly/hard 4e campaign and don't know many monsters than the basics like the beholder, medusa, catoblepas, and demi-lich.
