Expanded Blood Spear

You conjure three spears of blood, sending them out in a 20 foot cone. All creatures in the area must make a Constitution saving throw. A creature takes 4d6 acid damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every slot level above 2nd.
