Blood Boil

You unleash a surge of dark energy, causing the blood within the target's veins to seethe and boil. Make a ranged spell attack against a creature you can see within range. On a hit, the target takes 1d8 necrotic damage, and its blood boils within its body, causing it to become visibly agitated.

At Higher Levels: The damage of this spell increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
