Root

Root effects are a form of crowd control which cause the victim to be locked in place, unable to move. Root effects are sometimes 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 and melee/ranged attacks, but cannot move from its location as long as the effect is active.

Many root effects are subject to diminishing returns. Roots are movement impairing effects, and so can be countered with effects such as Hand of Freedom.
