Interrupts: The Button Everyone Should Know

Every class has an interrupt — a button that stops an enemy's cast. It is the single most underused ability in group content, and learning it early will carry you further than any gear upgrade.

What interrupting means

Enemies cast spells with a visible cast bar. Most casts can be stopped: your interrupt ends the cast instantly and usually locks that enemy out of casting that spell school for a few seconds. The ability never happens — no damage, no heal, no nasty debuff.

Interrupt versus crowd control

Crowd control — stuns, fears, polymorphs — also stops casts, but it controls the whole enemy and often has diminishing returns or breaks on damage. Interrupts exist only to stop casts, cost nothing, and are on short cooldowns. Use the interrupt first; save control for the casts that cannot be interrupted or emergencies.

Why it matters so much

In dungeons and raids, enemy casts are how mechanics happen: heals that undo your work, burst damage that one-shots the healer, debuffs that spiral into wipes. A well-timed interrupt deletes the mechanic entirely. Groups that interrupt reliably do harder content with worse gear than groups that do not.

Common mistakes

• Saving it for a special occasion — the cooldown is short; use it early and often on dangerous casts.
• Everyone interrupting the same cast — stagger kicks when you can; two interrupts on one cast means the next cast goes through.
• Interrupting harmless casts — learn which casts actually threaten the group; healers and high damage casts come first.
• Never keybinding it — if you have to hunt for the button mid-pull, it is already too late. Bind it somewhere comfortable.

How to practice

Turn on enemy cast bars in your UI settings, run a normal dungeon, and interrupt every cast that looks dangerous. Within a few runs it becomes reflex — and your groups will quietly have much easier nights.
