Cripple reduces the melee, ranged, and movement speed of its opponents.
The movement speed reduction does not affect targets which are immune to movement slowing effects.
A variation of this ability was proposed to be a new warlock ability in the Wrath of the Lich King expansion, but was later dropped.
- Hotfix (2009-05-13): "The Doomguard's ability Cripple now reduces ranged and melee attack speed by 20% instead of 45%. Cripple's slowing effect does not stack with other slowing effects such as Thunderclap and Infected Wounds."
- Patch 1.6.0 (12-Jul-2005): Targets that are immune to movement slowing effects will no longer be affected by Cripple's movement slowing effect. Melee and ranged attack speed slowing effects will still affect these targets.
