Incapacitate

Incapacitate or Knockout, previously called Disorient, is a form of crowd control that render a player or NPC unable to move or act for a short period of time. Incapacitate differs from Stun in that Incapacitate effects always break on damage, while Stun effects don't. Incapacitate effects are also often harder to break free from; a mage can for example break a stun by using Blink, but will be unable to do so if incapacitated.

Example of Incapacitate effects:
 * Rogue: Gouge
 * Paladin: Repentance (Talent)
 * Druid: Maim
 * Engineering gizmo Goblin Rocket Helmet and most bombs and grenades.
 * Horned Viking Helmet, a drop from Eric "The Swift", an elite dwarf only killable by Horde characters in Uldaman.
