Ring of Divine Nature – Spirit

Once per day, as an action, the wearer can issue a
command causing a protective magical force to
surround you, manifesting as a spectral glow
that emanates from you and your gear. You gain
5 temporary hit points for the duration. If a
creature hits you with a melee attack while you
have these hit points, the creature takes 5
radiant damage.
This effect ends when the temporary hit points
gained from the ring are lost or after one hour.
Its power recharges at the end of a long rest.
