With a simple command and a lunging cut in the air, you create a short-lived but destructive wave of pure necrotic energy from the edge of your weapon. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 necrotic damage on a failed save, or half as much damage on a successful one.

Creatures hit with the Fell Cut may see brief glimpses of traumatic experiences from their past or from their dreams, which may or may not be relevant.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
