Artificer: Spell-Storing Item

Whenever you finish a Long Rest, you can touch one Simple or Martial weapon or one item that you can use as a Spellcasting Focus, and you store a spell in it, choosing a level 1, 2, or 3 Artificer spell that has a casting time of an action and doesn't require a Material component that is consumed by the spell (you needn't have the spell prepared). While holding the object, a creature can take a Magic action to produce the spell's effect from it, using your spellcasting ability modifier. If the spell requires Concentration, the creature must concentrate.

Once a creature has used the object to produce the spell's effect, the object can't be used this way again until the start of the creature's next turn. The spell stays in the object until it's been used a number of times equal to twice your Intelligence modifier (minimum of twice) or until you use this feature again to store a spell in an object.
