World of Warcraft - Raid Strategy Guide - Oregorger

The storehouses of the Blackrock Foundry, laden with heaps and pallets of unprocessed Blackrock ore, represent a grand banquet feast for the ravenous rock-eating goren who have burrowed into the chamber. Oregorger is by far the largest of the invaders, gluttony swelling his frame far beyond the size of any goren previously seen in Draenor.

• Overview - Oregorger draws upon his reserves of Blackrock Ore to attack his enemies. When he has spent all his Blackrock Ore, he begins rampaging around in search of new Blackrock Ore to replenish himself. Once Oregorger is sated, he stops rolling and returns to fighting.
