Doroth'Admar (Warhammer +1)

This hammer, forged on the 223rd level of the Abyss, was made for the endless wars that consume the lives of devils and demons alike. Destroying truly great demons and devils furthers the hammer's potency.
When devils and demons draw near, the eyes of this hammer snap open. Striking a demon or a devil produces an effect akin to striking and anvil; flames and smoke pour out of the hammer and it deals an additional 3d6 damage.
