Cartouche of Knowledge

This amulet is carved from lapiz lazuli with scenes of knowledge, and seems to glow sapphire-blue from within. While attuned to the cartouche, you gain a flying speed of 25 ft. In addition, once per long rest you can use an action to cast any cantrip from the wizard spell list. If you are attuned to at least three cartouches, you can instead cast any wizard spell of 1st level or lower once per day; if you are attuned to at least five cartouches, you can instead cast any wizard spell of 2nd level or lower once per day. Your spellcasting ability for this spell is Intelligence. While attuned to a cartouche, any other cartouches do not count towards the number of items you can attune to. For every other cartouche you are attuned to, the flying speed granted by this cartouche increases by 5 ft.
