Consume Magic (priest ability)

Consume Magic was one of the priest racial abilities available only to blood elf priests. It allowed the priest to consume a priest-specific buff on themselves in order to regain mana. This was very useful as part of a priest's mana regen rotation.

This ability allowed a priest to consume one of his or her own buffs, such as Inner Fire, Touch of Weakness, Power Word: Fortitude, and so on in order to regain mana. In long mana intensive fights, this could be incredibly useful. The mana returned scaled with the priest's level as well.

Place a Rank 1 Inner Fire (or Touch of Weakness) on yourself, and then use Consume Magic. If the proper buff gets consumed, then you have just regained a good chunk of mana at almost no cost. However, it is advisable to not interrupt mana regen; instead, Consume Magic should be used in between casts.
