Grants 1 point of Retribution Damage.
Retribution Damage: When a melee attack deals damage to a target possessing Retribution Damage (RD), the attacker takes damage equal to the target’s total RD. Ranged attacks, whether physical or magical, do not trigger RD. If an attack would have caused damage but is completely negated (e.g., Cloak of Shadowskin) or the attack’s damage is reduced to zero (e.g., melee damage reduction),
Negates all special attacks that might be directed against the wearer’s armor or weapons. (E.g., a rust monster’s corrosion ability or sundering attacks from SeyLah’s +2 Sundering Cestus)
