Bloody Mark

You fling a small globule of blood to remotely etch a rune of hemocraft into a creature's skin. Make a ranged spell attack. On a hit, the target takes 1d10 piercing damage, and the next spell attack made against the target before the end of your next turn has advantage.

Blood Magic. This spell can be cast without its material component. If you do, you lose hit points equal to your proficiency bonus.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
