Did you want information about the Curse Gaming website?

Curse is a Dispel Type that is inflicted by various bosses, mobs, and most commonly, by Warlock players. (Curse of Weakness for example. See Warlock abilities for a full list). Curses do only exist as Debuffs, not as Buffs. In most cases, they only have a negative effect without doing damage, but some of them are actually DoTs (such as Curse of Agony). The border around a Curse type effect's icon in a player or mob's debuff bar is purple.
