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.

Victims of your Frost Fever disease are Chilled, reducing movement speed by 50% for 10 sec, and your Chains of Ice immobilizes targets for 3 sec.

Drain vitality from an undead minion, healing the Death Knight for 50% of her maximum health and causing the minion to suffer damage equal to 50% of its maximum health.

When you land a damaging Death Coil, Frost Strike, or Rune Strike, you have a 45% chance to activate a random fully-depleted rune.

Surrounds the Death Knight with a swirling tempest of frigid air for 8 sec, chilling enemies within 8 yards every 1 sec. Each pulse reduces targets' movement speed by 15% for 3 sec, stacking up to 5 times. Upon receiving a fifth application, an enemy will be stunned for 6 sec.
