You create a crystalline shard and fling it at one creature within range. Make a ranged spell attack against the target.
On a hit, the target takes 1d10 piercing damage. Hit or miss, the shard then bursts into sharp fragments. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 piercing damage.
At Higher Levels:
When you cast this spell using a spell slot of 2nd level or higher, the piercing damage increases by 1d6 for each slot level above 1st.
