Blood Spatter

A stream of blood from an open wound becomes torrential, splattering on all creatures within a 15ft cone, originating from you. Each creature in the area must make a Dexterity Saving Throw or take 4d8 necrotic damage, or half as much on a successful save. You take damage equal to half the amount rolled.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
