Immobilization

Immobilization (sometimes root) is part of TERA's combat system. It is state where player or monster cannot move, but can use skills. Immobilization wears off then player is attacked.

Immobilization happens when Slayer or Valkyrie (after PVP nerfs) backstabs player in PvP or Sorcerer casts Time Gyre. When this happens to you, turn your face to opponent player. This lowers the amount of damage they deal. They will most likely cast next stun, or knockdown, or some of their big attack skills like Meteor Strike.

Certain skills remove immobilization. These include movements skills like Charge and Rush, Backstab.
