Bone Spear

Spears of bone burst from the ground in a 5-foot cube that you can see within range. Any creature in the cube must succeed on a Dexterity saving throw or take 1d8 piercing damage.

You can choose whether the bones disappear or fall on the ground. If the fall to the ground the pile of bones remains until the spell ends or until you create another pile of bones with this spell. When you cast a spell that requires you to choose the bones or corpse of a Medium or Small humanoid, you can choose the pile of bones created by this spell instead.

The spell's damage increases by 1d8 when you reach 5th level (2d8) 11th level (3d8) and 17th level (4d8)
