* Death Coil: This spell will no longer sometimes cause the death knight to animate a swing twice.

In order to end the effect, the player controlling the Risen Ghoul must right click on the unit portrait and dismiss the pet. In addition, using this ability on a player whose level is too low will now give a “Target is too low level” error message instead of “You have no target.”

* Rune of Cinderglacier: Charges of this will now only be used if the target actually took damage from the attack.
* Scent of Blood: This talent can no longer be triggered by environmental damage.
* Scourge Strike: The tooltip incorrectly stated it did 60% weapon damage increased by 9% from diseases, when it was actually 45% increased 11% from diseases. The tooltip has been corrected, but the damage done is unchanged.
* Sigil of Awareness: The tooltip on this incorrectly indicated it added much more damage than it actually did. The tooltip has been corrected to show the actual bonus.
* Summon Gargoyle: The Gargoyle will no longer re-attack rogues after they Vanish, or night elves who use Shadowmeld. Monsters will stop trying to chase a Gargoyle after it flies away. The debuff on the target indicating he or she is being pursued by a Gargoyle will no longer display the duration, and will be removed when the buff is removed from the death knight. Max duration in the tooltip changed to 40 seconds.
