Ioun Stone Moonstone Orb

Grants 5 points of Retribution Damage. If the attacker is an Accursed monster, the total Retribution Damage granted is +10.

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), RD does not trigger.
