When being attacked physically (with a melee attack) you can immediately block and return the damage to the caster. If you succeeded a difficulty check or the enemy rolled lower than your armor class for this attack, double the returning damage. You can only use this skill once per three rounds. You cannot use this reaction if you were ambushed, or if the enemy had a surprise effect on you. You cannot use this skill if the attack was non physical such as a psychic attack or an arrow shot.
