Gunnr spawns adds that have aggro requirements. The adds are a misty warrior, a misty crusader and a misty brawler, they cannot be tanked by the class who's name they share. E.g. a misty warrior must not be tanked by a Guardian or a Berserker. If threat is pulled by any scout/mage/priest or improper fighter a fail script will occur killing all of a certain class depending on which add it is.
