Bone Shards

Like a barbaric knife, you hurl a necrotic shard of bone at a creature, making a ranged spell attack. If you hit roll 1d10 piercing damage. Regardless of whether of not you hit, roll 2d6 necrotic damage as the shard explodes into a cloud of deadly shrapnel. Your target and all creatures within 5 feet must make a Dexterity saving throw. On a success they take half damage.

When cast this spell at a 2nd level spell slot or higher, the necrotic damage increases by 1d6 for each slot level above 1st.
