Icehawk Riftwing

Icehawk Riftwing is a Gloombat found in the first level of the Kurast Sewers. Icehawk Riftwing is found in Level One of the Act Three Sewers, below Kurast. He is found near the steps leading down to level two. Killing Icehawk is not required to complete any quests, but since he's found near the steps that must be descended to acquire Khalim's Brain, Icehawk might as well be taken care of.
