Target something across the zone and warp back and forth real fast killing it. It was best used with the NoDelay hack which killed insanely fast. You could clear a whole zone in no time at all. My SK would clear an instance. There was one that would respawn and I would just let it keep clearing. It was great cause once you popped Mortal Coil you just kept yourself healed over and over. Then people did stupid stuff out in the open and bye bye fun toys.
