Bone Splinters

You toss a bone into the air and split it into shrapnel with a swift hand motion or a softly spoken command. The splinters home in on one creature within range, avoiding anything in their path aside from the target. Make a ranged spell attack against the target. On a hit the target takes 1d8 piercing damage and must succeed a Dexterity saving throw or take an additional 2d6 piercing.

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