Arcane Mark

You inscribe a magical signature on an object or structure within reach. The inscription can take the form of a single symbol, word, or other design as long as it can occupy up to a 6-inch square on the surface of the structure or object. The mark cannot be removed by nonmagical means and is unique to you. Attempts by creatures other than you to replicate the design of your inscription automatically fail. Once you have inscribed an object or structure with this spell, you cannot target it with this spell again for as long as it remains inscribed.
You can choose to cast this spell immediately after you cast a spell as an action. If you do so, instead of inscribing a magical signature on an object or structure, you give that spell a per- sonalized flair that identifies it as a spell cast by you. Creatures that observe the spell’s casting or effects and have knowledge of your existence instantly recognize the spell as one cast by you.
