Ethereal Knives

As you hold out your hand to cast the spell, an ethereal fan of knives shoots forth from your palm. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d4 force damage on a failed save, or half as much damage on a successful one.

Additionally, regardless of the outcome of the saving throw, creatures in the cone take 1d6 psychic damage, as the magic knives' ethereal presence affect their state of mind for a moment.

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