Ring of Divine Nature – Earth

Once per day, as an action, the wearer can issue a
command causing a protective magical force to
surround you, manifesting as a gasseous cloud
around 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 poison 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.
