Mass Confusion is a level 6 Hexes spell that tries to confuse all monsters in your line of sight. Unlike Alistair's Intoxication, it works on monsters that are non-natural, poison resistant, or of animal or lower intelligence. However, it is resistible by magic resistance, making it ineffective against many monsters in the later game.
