// Using 'old' behavior for devotion vs reflect damage? (Note 2)// Default is 0 (official). If 'devotion_rdamage' is > 0 (chance to devote the reflected damage),// when player with devotion attacks player with reflect damage ability (item bonus or skill),// the damage will be taken by the person who provides devotion instead the attacker.devotion_rdamage: 0
