Zin'rokh, Destroyer of Worlds (level 60)



Zin'rokh, Destroyer of Worlds is a two-handed sword with stamina and attack power. Arguably the best DPS and top-damage weapon pre-MC, comparable, if not better than, with items such as Sulfuron Hammer and Obsidian Edged Blade.

Its older brother, Jin'rohk, The Great Apocalypse drops from the last boss, Zul'jin in level 70 10-man raid instance Zul'Aman.
