Prayer of Spirit

Prayer of Spirit is a priest ability, trainable at level 60. It grants all party or raid members a buff that increases spirit for 1 hour.

Cataclysm
With Cataclysm, Divine Spirit and Prayer of Spirit will be removed from the game. As Spirit will be 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 will not boost Spirit either.
