1st-level transmutation

Casting Time: 1 action
Range: Touch
Components: V, S
Duration: Permanent (objects) or 1 year (creatures)
Classes: Bard, Sorcerer, Wizard

You inscribe a personal rune, sigil, or mark upon an object or creature you touch. The mark can be up to one square foot in size and can include a complex personal sigil, small drawing, or longer inscription of up to 25 words. The writing can be visible or invisible (your choice), and can be made to glow faintly in darkness. The mark can be placed on a surface without harming the material.

The mark can also be placed on a creature. If they are unwilling, they can make a Wisdom saving throw to avoid being marked. A creature marked by this spell can repeat the saving throw every thirty days, ending the effect on themself on a success. The mark automatically fades after one year.

The mark is durable. When placed on inanimate objects, it cannot be removed except by you or by a successful dispel magic.
