Hammer of the Astral Plane



The Hammer of the Astral Plane drops from Kel'Thuzad in the 10-man version of Naxxramas.

Note
The Hammer of the Astral Plane is an upgraded version of the Hammer of the Twisting Nether, which also dropped from Kel'Thuzad in the original Naxxramas. It matches with the Aegis of Damnation, which drops from Maexxna.
