The Prayer Ring (いのりのゆびわ Inori no yubiwa) is an accessory that first debuts in Fire Emblem Gaiden. In Gaiden, when equipped, the Prayer Ring restores 5 HP to its wearer at the beginning of each turn, alongside permitting them to perform a guaranteed critical hit when their HP falls below its half-mark. Unlike its Genealogy of the Holy War counterpart, the effect of this incarnation of the ring resembles the Wrath skill more than it does the Prayer skill.
In Genealogy of the Holy War, the Prayer Ring manifests as the Prayer Bracelet (祈りの腕輪 Inori no udewa), and which confers the Prayer skill onto its wearer. The ring must be placed into the inventory of any character for this property to take effect.
