Not sure if this is a bug or feature - it's funny enough that it might be worth keeping as a feature.

Chaos brothers (or sisters) randomly execute special monk powers and one of them is circular kicks... they usually end up angering other monsters, who promptly kill the chaos monk. This is especially hilarious when you fight a group of them (IIRC they appear in groups in the wilderness sometimes), as the battle is soon a total chaos monk chaos.
