Divine Troth

Feats

Once per day the divine guardian pledges her protection to a willing creature for the day. The creature gains benefits while remaining adjacent to the divine guardian. When a target of the divine guardian's divine troth ability is attacked, if that target is within her melee reach, she may use an attack of opportunity to provide her ally with a +4 bonus to AC. The divine guardian can intercept a successful attack against the target of her divine troth ability once per round, taking full damage from that attack and any associated effects.
