Ring of Spell Storing

This ring stores spells cast into it. It can hold 5 levels worth of spells. Any creature can cast a spell of 1st through 5th level into the ring by touching the ring
as the spell is cast.
While wearing this ring, you can cast any spell
stored in it. The spell uses the slot level, save DC,
attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the ring is no longer stored in it, freeing up space.
