Is there a spell I can use to cure insanity? If so, which one? I'm stuck in the Shrine right now because the character with the monkey figurine is insane - and I don't want to trek all the way back to the city to get him cured. Or is there a way to steal the figurine from one of my own guys? How annoying, I hate those damn scarab guardians or whatever they are...

The level 7 Spirit spell "Exorcism", will cure insanity (among other things). Whether or not you have the spell is another thing though, hope you do.

6th level Spirit spell "Restore Health" or a potion of restore health works too.
You cannot access an insane character's inventory to trade the item to another? Interesting!
