Blood Rupture

You make a melee attack against one creature within 5 feet of you with a weapon wet with your own blood. On a hit, you take 1d6 damage, the target suffers the weapon attack’s normal effects, and you cause blood to leap from the target to a different creature of your choice that you can see within 10 feet of it. The second creature takes necrotic damage equal to 1d6 + your spellcasting ability modifier.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d6 necrotic damage to the target on a hit, and the necrotic damage to the second creature increases by 1d6. Both damage rolls increase by 1d6 at 11th level (2d6 and 3d6) and 17th level (3d6 and 4d6).
