Blood Scythe

Using your own blood, you create a phantom scythe that sweeps out in front of you. Each creature in a 10 ft cone must make a Constitution saving throw. A creature takes 3d10 necrotic damage on a failed save, or half as much damage on a successful one. You are healed for half the damage dealt rounded down.

You can only cast this spell if you are below your hit point maximum.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
