Devastator is a crafted legendary mace in Diablo III. It requires character level 70 to be used. The level 60 equivalent is the Earthshatter.
Compared to the latter, Devastator loses the ground-shattering attack, but becomes one of the two non-class-specific one-handed weapons (the other being The Burning Axe of Sankis) that can increase damage dealt by Fire skills.
