Unholy Aura is a passive death knight ability learned at level 60 for death knights with the frost or unholy specializations.
Before Wrath of the Lich King
Prior to WotLK, Unholy Aura was possessed by death knight bosses such as Baron Rivendare. It did about 150 damage every 2 seconds to anyone in range.
- Patch 5.0.4 (28 August 2012): Re-added; changed from All party or raid members within 45 yards of the Death Knight move X% faster. This effect does not stack with other movement improving effects.
- Patch 3.1.0 (14-Apr-2009): Replaced with Improved Unholy Presence. Allows the death knight to keep the movement speed bonus of Unholy Presence in any presence, and increases rune regeneration rate while in Unholy Presence.
