You conjure golden chains of divine energy that lash out and bind the attacker. The creature must succeed on a Charisma saving throw or become restrained until the start of your next turn. While restrained in this way, the creature cannot take attack actions or cast spells that target other creatures. Regardless of the result, the intended target of the attack gains resistance to all damage from the triggering effect. If you expend 1 Holy Power, the restrained creature also takes 2d8 holy damage.
