Corrosive Blood

As you hold your hand out with fingers spread, a corrosive spray of blood streams forth from your open palm. Each creature in a 15-foot cone must succeed on a Dexterity saving throw or take 1d6 acid damage.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
