World of Warcraft®

Draw forth the infection from an enemy, consuming your Blood Plague and Frost Fever diseases on the target to activate a random fully-depleted rune as a Death Rune.

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.
