World of Warcraft®

Surrounds the Death Knight with a vile swarm of unholy insects for 10 sec, stinging all enemies within 10 yards every 1 sec, infecting them with Blood Plague and Frost Fever.

An unholy pact grants you the ability to fight on through damage that would kill mere mortals. When you would sustain fatal damage, you instead are wrapped in a Shroud of Purgatory, absorbing incoming healing equal to the amount of damage prevented, lasting 3 sec.

If any healing absorption remains when Shroud of Purgatory expires, you die. Otherwise, you survive. This effect may only occur every 3 min.
