The Prayer Ring (いのりのゆびわ Inori no yubiwa) is an accessory that debuts in Fire Emblem Gaiden. In Gaiden, when equipped, the Prayer Ring restores 5 HP to its wearer at the beginning of each turn. It also guarantees a critical hit when the wearer's HP falls below its half-mark, which resembles the Wrath skill.
In Fire Emblem: Three Houses, it returns as a defensive item that restores 10% HP every turn. It has a hidden effect of granting Miracle for free once again, although this is not indicated by its description.
