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.

You passively move 10% faster, and movement-impairing effects may not reduce you below 70% of normal movement speed.

When activated, you gain 30% movement speed and may not be slowed below 100% of normal movement speed for 6 seconds.

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.

Each damaging Death Coil, Frost Strike, or Rune Strike generates 2 Blood Charges, up to a maximum of 12 charges. Blood Tap consumes 5 Blood Charges to activate a random fully-depleted rune as a Death Rune.
