Devastator

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.

Crafting
Devastator can be crafted using the Plan: Devastator, 64000 gold, 20 Reusable Parts, 20 Arcane Dust, 30 Veiled Crystals, Arreat War Tapestry and Westmarch Holy Water.

Prior to Patch 2.0.6., it also required one Shattered Core, which dropped from unique Sand Dwellers.
