Only reflects physical damage (melee + elemental attribute too). Physical Strike = damage from Physical attacks (damage you would receive without Dark Barrier). Reflected Damage is magic type damage. It is reduced by Attacker's Magic Resistance but ignores Attacker's MD. Dark Resistance raise: your Dark Resist % + Dark Resist Up For Example: you have 50 % Dark Resist and mastered Dark Barrier. Your Dark Resist with Dark Barrier active = 50 + 20 = 70 % Formula OK.
