Zenoth'Admar

The soul of Lord Hammerkill, angel-made-man who departed the heavens to give his son a chance at the quiet life, resides in this hammer.
This hammer can only be wielded by Torok Hammerkill. It deals an additional 3d6 to any creature not native to the Material Plane of Existence. The hammer can be summoned at any time by speaking its true name. If this hammer is on the same plane of existence as Torok Hammerkill, it will fly directly to him.
