Mordullu's Promise is a legendary axe in Diablo III, added in patch 2.4.0. It requires character level 70 to drop.

The unique affix restores Mana instantly upon cast, effectively making Firebomb a way to quickly recover from even the most costly spells. However, for the purpose of Depth Diggers and Boyarsky's Chip, it will still not make Firebomb a Primary skill.

"When I move to the unformed land, you may throw my skull at the unwise, and I will return long enough to invigorate you." — Mordullu's promise to his heirs.


Originally, this item was named Fenris Tooth, and had alternate description:

Lost in the wilderness and set upon by wolves, a blacksmith howled in frustration at his fate. The lead wolf, a snaggletoothed black beast, heard in this wail the man's primal desire to survive and held his pack back. After exiting the forest, the smith created a vicious, fire-howling axe inspired by his experience.
