I keep getting nailed by these awful screaming head things (I cannot recall the name of the monsters) in the graveyard. They keep throwing Terror spells and Insanity Spells on my party and cast "Eye for an Eye" so I have no chance whatsoever. What is the best approach to these? I dont have any good spells (not that I know of) to prevent or cure the insanity. It is entertaining to see my characters laugh, but I would like to win this battle.
