Amulet of Forbidden Knowledge

While attuned to this item, you know 1 additional 3rd level or lower spell from your class spell list than you otherwise would. Casting this spell expends spell slots as it normally would, and the spell can be cast at a higher level if you have the ability to do so. To imprint a spell upon the amulet, you must meditate upon it for 8 hours while wearing the amulet. The same applies for changing the spell imprinted upon the amulet.
