This wand stores spells cast into it, holding them until the attuned wielder uses them. The wand can store up to 5 levels worth of spells at a time.
Any creature can cast a spell of 1st through 5th level into the ring by touching the wand as the spell is cast. The spell has no effect, other than to be stored in the wand. If the wand can't hold the spell, the spell is expended without effect. The level of the slot used to cast the spell determines how much space it uses.
While wearing this wand, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster. Additionally any spell cast from the wand doesn't require concentration and lasts for the full duration in the spell description. The spell is otherwise treated as if you cast it. A spell cast from the wand is no longer stored in it, freeing up space.
