Interrupt

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 except by breaking their bar. Skills, traits, and sigils that have bonus effects upon interrupting foes will activate on foes with defiance bars if an interrupt skill is used during an attack windup. There is a 3-second cooldown between each interrupt to prevent the same effect from activating multiple times during the same attack animation.

Effects causing interruption

Most interrupts are caused by control effects. As such, the stability boon provides immunity against interrupts. Stun break skills will recover from Interrupts. Targets that can take Fall Damage, i.e. PvP and WvW, can be moved off ledges or cliffs.

Trivia

The Guild Wars Wiki has an article on Interrupt.

• Interrupts as they existed in Guild Wars (see here) are not as prevalent in Guild Wars 2 because of their dependence on low network latency to be used effectively.
