Poltergeist: trips, feints, sometimes knocks equipment out of others, causes fear. Doesn't go away until you die.

Black Mummy: Your info is better than mine - hides in the sand though

Akresh: Same info as yours, except also has porcupine spine like thing

Mhournhul:

I had two different types of wraiths - think they were really similar to yours, but also one of them had mental knife like thing + energy drain

Patchwork Dead: Attacked anyone/everyone who held a weapon automatically - steals weapons during combat (there's a log somewhere where a battle thief was attacked while hidden cuz the dead stole his weapon).
