Blood Burst

Make a melee spell attack against a creature you can reach. On a hit, the target takes 1d8 necrotic damage. The spell’s damage increases by one die when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8). If this spell is used after the target has been targeted by the Sanguine Touch spell, the die roll becomes a d12.
