Implemented 'devotion_rdamage' on conf/battle/skill.conf for suggestion on http://rathena.org/board/topic/78620-renewal-devotion/
// Using 'old' behavior for devotion vs reflect damage? (Note 2)
// Default is 0 (official). If 'devotion_rdamage' is > 0 (chance to devot 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
