This spell is a minor magical trick that novice spellcasters practicing ink magic use for various purposes. Wielding the quill and using the ink provided in the spell's casting, you write on parchment, paper, or some other suitable writing material and imbue one of the following effects:

Signature: You mark a magical signature. You only have one signature you can create, unique to you. It is impossible to change your signature, or to imitate another in any way when you cast this spell. Further, this special signature is impossible to reproduce authentically by magical or mundane means. A creature that knows this spell or that is trained in Arcana instantly recognizes any attempted forgery.

Secret: You bind the ink used with a simple illusion which lasts until dispelled. The ink is invisible, revealed by temporarily by a moderate amount of hear, direct moonlight, or magical light. Alternatively, you reveal any ink hidden by this spell on a piece of writing material you touch.

Tattoo: You apply the ink to the skin of a willing creature and imbue the ink with semi-permenance, as though the ink were tattooed into the creatures skin. The target can remove the ink permanently at any time using an action.
