Bone Splinters

You move your arms around crating a formation of black circling clouds in the sky within range. After the clouds are formed a black almost portal-like blank space will appear between them and from it a huge amount of pieces and splinters of bones will emerge falling down to everyone in an cylinder of a 20-foot-radius requiring each creature in the area to make a Dexterity saving throw. Each target will take 2d6 bludgeoning damage and 6d8 piercing damage, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the piercing damage increases by 1d8 for each slot level above 5th.
