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.

Continuously converts Runic Power to health, restoring 3% of maximum health every 1 sec. Only base Runic Power generation from spending runes may occur while Conversion is active. This effect lasts until canceled, or Runic Power is exhausted.

When you land a damaging Death Coil, Frost Strike, or Rune Strike, you have a 45% chance to activate Runic Corruption, increasing your rune regeneration rate by 100% for 3 sec.

Corrupts the ground in a 8 yard radius beneath the Death Knight for 10 sec. While standing in this corruption, the Death Knight is immune to effects that cause loss of control. This ability instantly removes such effects when activated.
