Bone spear

With a swirl of your hand and a drop of bone dust onto the ground you cause a spear of bone to launch itself from the ground by your feet into a target you choose within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the spear then explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 necrotic damage.

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