Considered the true final boss of Karazhan. A difficult encounter with ground and air phases requiring high raid awareness.
Ground Phase: Tank faces Nightbane away from the raid. Move out of Charred Earth. Air Phase: Kill skeletons quickly, avoid Rain of Bones, heal through Smoking Blast on random targets. When Nightbane lands, let the tank establish threat before DPS resumes. Tremor Totem for Fear.
