Divine Spirit

Divine Spirit was a priest ability, trainable at level 30. It granted a friendly target a buff that increased spirit for 30 minutes.

Cataclysm
With Cataclysm, Divine Spirit and Prayer of Spirit were removed from the game. As Spirit is the primary mana-regeneration stat, Blizzard doesn't want it to vary as much between solo, small group, and raid play. Blessing of Kings and Mark of the Wild no longer boost Spirit either.
