Blood Spray

As you hold your hands with thumbs touching and fingers spread, crystalized blood shoots forth at all those in front of you. Each creature in a 15ft cone takes 3d4 necrotic damage. Creatures affected must also make a Constitution saving throw. On a failed save, the target is blinded until the end of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 2d4 for each slot level above 1st.
