Crowd Control (abbreviated CC) refers to spells and abilities which limit an opponent's ability to fight. CC abilities are used to reduce the number of mobs that the group fight at once. Due to the fact that most groups cannot tank more than a certain number of elite mobs at a time, crowd control is often essential to prevent a group from being overwhelmed. For a guide on how to effectively use CC in instances, see the Instance grouping guide for a crowd controller.
All instance bosses are immune to crowd control.
Types of CC include Charm, Daze, Fear, Root, Sleep, Slow, Snare, Incapacitate, Disorient and Stun. The following Primary Crowd Control Abilities can be re-applied an unlimited number of times, and take a mob effectively out of combat as long as the CCer wants to:
These Secondary CC Abilities can control a mob for some time, but either break easily, need frequent reapplication or have other restrictions which make their continued use impractical, and therefore cannot be generally used to take a mob out of combat indefinitely:
Rogue - Sap (humanoids only rank 1-3, Humanoids, Beasts, Demons and Dragonkin rank 4, cannot be applied in combat), Blind, and various stuns and stun-lock tactics
