Ok'thor the Breaker

Ok'thor the Breaker is a level 53 elite ogre mage that sometimes appears in Blackrock Depths.

When a player enters the Ring of Law in the Depths, an arena event will occur where players have to face three waves of non-elite enemies and finally an elite mini-boss. Ok'thor is one of six possible mini-bosses that could appear. The other ones are Anub'shiah, Eviscerator, Grizzle, Hedrum the Creeper, and Gorosh the Dervish.
