Teeth (DN)

You hold your outstretched hand towards your enemies, releasing a swarm of bone shards from your outstretched fingertips. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 piercing damage on a failed save, or half as much damage on a successful one.

A creature within the first 5' of the area of effect makes the Dexterity saving throw with disadvantage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6, and the range increases by 5', for each slot level above 1st.
