currently, if you blind an ant and convince the ant that the lich king standing next to him is you, you can get the ant to nibble away at the lich king until he eventually kills him. Really, the lich king should identify that the ant is a liability, and dispatch him. We could implement this as all enemies having bad tempers and getting pissed off easily.
alternatively, we could implement some kind of verbal communication whereby the victim can say "hey, it's me" so the blind individual won't be confused anymore.
