Fueled by Death

Fueled by Death Passive Consuming a corpse increases the Necromancer's movement speed by 3% for 5 seconds. This effect can stack up to 10 times. "Few have dared to master the dark arts, but then, there are few like us." — Master Necromancer Ordan

Fueled by Death is a Necromancer passive skill, unlocked at level 10.

In-game

The 3% bonus is added per corpse consumed, not per cast. Each stack refreshes the duration of all other stacks.

As of patch 2.6.1, this effect can increase speed above the usual +25% limit.

Consuming a corpse contributes to this effect when done by either Corpse skill (Revive, Devour, Corpse Explosion or Corpse Lance) or by the Decay Golem.
