An interrupt is any action that prevents a foe from completing its current action. Skills which are interrupted have a 5 second cooldown before they can be cast again. Chains are reset to the first skill in the chain any time the player is interrupted. Skill activation can be cancelled by a player casting the skill, but is not considered interruption. When an interrupt occurs, the word Interrupt! appears on the screen. Foes with a Defiance Bar cannot be interrupted; however Skills, traits, and sigils that have bonus effects when interrupting foes will activate when used against foes with defiance bars as though they had been interrupted.
Effects causing interruption
- Daze – Disables all skills for a short duration.
- Knockdown – Knocks the target on ground, preventing movement and actions for a short duration.
- Launch – Throws the target in the air over a short distance, preventing movement and actions for a short duration.
- Pull – Pulls the caster to the target or the target to a specific location and disables them for a short duration.
- Knockback – Pushes the target away and on the ground, preventing movement and actions for a short duration.
- Stun – Prevents movement and actions for a short duration.
- Float - Causes the underwater target to move upwards.
- Sink - Causes the underwater target to move downwards.
- Fear – Disables all skills and causes the target to flee directly away from the caster for a short duration.
- Taunt - Forces the affected target to run towards the source of taunt with all skills except stun breakers disabled while using their auto-attack skill.
