Cripples the target, reducing movement speed by 20%, increasing time between melee and ranged attacks by 20%. Lasts 20 sec.
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."
