Chord of Shards

You strike a chord whose notes transform into a shower of razor-sharp, crystalline shards. Each creature within a 15ft cone originating from you in a direction of your choice must make a Dexterity saving throw, taking 2d6 piercing damage on a failed save, or half as much on a successful one.

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.
