Bronze Protector

Though learning how to harness your divine power was rigorous and involved a great deal of suffering, you have learned to transform some of it into a shining second skin that protects you from harm.

Metal Skin. You can use a bonus action and expend a herald spell slot to cover your body in a bronze alloy of divinity and metal that protects you from harm. For the next minute, whenever you take damage other than lightning or psychic damage, you reduce the damage you take by an amount equal to the level of the expended spell slot (before calculating resistances ). You can end the effect as a free action.
