Root effects are a form of crowd control which cause the victim to be locked in place, unable to move. Root effects are often known as immobilize effects in-game. A root effect differs from a stun effect in that the target is still able to use abilities, spells or melee/ranged attacks, but cannot move from its location as long as the effect is active.
Examples of abilities and procs that can root opponents:
- Druid: ,
- Hunter: (pet), , , (pet), (pet)
- Mage: ,
- Warrior: Glyph of Hamstring,
Although the Death Knight's Chains of Ice ability may look like a root effect, it only acts to slow the target by 95%. This effect may not, then, be removed with root dispels (see below).
If a mob with no ranged attacks is rooted from range, it will be unable to attack its current aggro target. However, if players are standing in melee range, it will attack the player that has the highest threat level. Thus, it is not wise to stand near a rooted mob, or root one within a crowd of players without prior warning.
