Magic Weapon Abilities - Retaliation
A suit of armor with this special ability strikes back at foes who hit hard in melee. Each time the wearer takes 10 or more points of damage from a single melee attack, the armor deals 1d6 points of damage to the attacker. If the wearer is dropped to below 0 hit points by a melee attack, the armor strikes the attacker for 3d6 points of damage. The damage from retaliation armor is treated as magic for the purpose of overcoming damage reduction.
