"lay on hands"
Their devotion to their god allows some holy warriors to cure their own wounds by placing their hand on their wound and channeling divine healing power. As the healing comes through a direct connection to their god, the efficiency of the healing process is determined by charisma, rather than vitality. Lack of training does not cause the attempt to fail, but limits the maximum amount that can be healed. Mastery speeds up the healing process by 1/3 or 1/2, respectively.
