Prayer of Mending (abbrv. ProM) is a priest ability learned at level 68. It is a reactive healing buff similar to Earth Shield. It will not actually heal the target when cast on them, but instead leave a buff on the target. When the buffed target takes any damage, the buff will heal the target and move to another random raid member within 20 yards. The buff has a maximum of 5 charges and will not proc from environmental damage (falling, lava, fatigue, etc) nor spells that reduce the caster's own HP, such as Warlock Lifetap. (Spells that actually cause damage to the caster, such as Warlock Hellfire will still proc the buff.).
