The mushrooms take away a strength point which you can get back with an antidote, no big deal. But later on there is a guy that takes away a max strength point which really sucks.

I think the dolls take you down to 1 experience point below the previous level. So they really suck when you are about to level up, not so much when you just finished leveling up.

And the guys that make you confused and walk in random directions suck because they do it when you are surrounded by other strong enemies and you can't really avoid them.
