Ring of Dying
A reward for returning Arabelle to her parents.
As an action while wearing the ring, you can cast the revivify spell at will, with a range of 60 feet and requiring no material components.
Curse. Attuning to this ring curses you and as long as you remain cursed, you cannot remove the ring. The ring becomes nonmagical if the curse is ever removed. If you cast revivify from the ring, your maximum health immediately drops to zero (0) and you will immediately die.
