“You, O Lord, will protect us.”
-Psalm 12:7

You gain a +1 Bonus to AC while you wear this magic ring.

This ring has 2 charges. As a bonus action, you can expend a charge and a burst of heavenly energy radiates out from you in a 30-foot-radius-sphere. All creatures that are hostile to you within this area must succeed on a DC 17 Strength saving throw or be pushed 15 feet from you and knocked prone. A creature moved in this way can spend its reaction to avoid becoming prone. Fiends and undead have disadvantage on the saving throw.
