A creature can spend 1 Hope to store a spell of level 5 or lower from a domain card they own within the ring. Only one spell can be stored at a time, and storing a new spell replaces the previous one. Storing the spell counts as successfully casting it for spells that can only be cast once per rest. While wearing the ring, a creature can cast the stored spell using their own Spellcasting Trait. The spell then disappears from the ring.
