Blood Bolt

You hurl a mote of blood energy at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 necrotic damage. Undead targets or targets immune to necrotic damage take half as much force damage.

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