Blood Storm

A slashing storm of blood forms a ripping vortex with a 15-foot radius around you or a point of your choice within range. Each creature (other than if you casting it with a range of Self) within range must make a Dexterity saving throw. On failure, they take 3d8 slashing damage. On success, they take half as much damage.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 3d8 for each slot level above 2nd.
