Essence Break

You hold your hand out as small tendrils of colored smoke quickly dart and surround each creature in a 15-foot in front of you. As you finish the casting the tendrils pull through the affected targets attempting to rip out a part of their life essence. Each affected creature must make a Constitution saving throw. A creature takes 4d6 necrotic 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 each slot level above 2nd.
