Doomsday Clock

A Doomsday Clock is a timer of some sort that will trigger a permanent Enrage or other presumably fatal outcome once it expires. The usual intent is to force the raid into completing the encounter in a timely fashion.

If the boss has no other particular gimmicks but does have a relatively aggressive Doomsday Clock, it is probably a Gear Check. Doomsday Clocks can be more serious during Hard Mode.

Examples

• Naxxramas
  • Patchwerk is a straightforward example of a boss who will wipe the raid once his timer runs out.
