Blood Letting

You hurl an enchanted scalpel at a creature within range that has a vascular system, causing it to bleed profusely. Make a ranged spell attack against the creature. On a hit, the creature takes 2d8 points of necrotic damage. At the start of each of its turns, the creature suffers an additional 1 necrotic damage until it staunches the wound. The creature can staunch the bleeding as a bonus action.

This spell’s damage increases by 1d8 when you reach 5th level (3d8), 11th level (4d8), and 17th level (5d8).
