The most powerful AoE the DRK has, mixed with mitigation on a job that lacked filler mitigation until the max level.
Every pull should have been 1 unleash, followed by a DA+DP.
From there you focus on MP maintenance, + ADs.
(the only time you couldnt afford to start with DA+DP was on pulls of more than 2 groups of mobs, which was mostly only in expert roulette, but you still built up towards it within a Siphon Strike.)
