The caster draws calcium from thin air to form a razor sharp fragment of bone and hurls it at an enemy. Make a ranged spell attack against your target to pierce it with the bone spear. On a hit, target takes 1d10 piercing damage. When cast at 5th level and above you may choose an additional target for each additional spear.

At Higher Levels: This spell's number of projectiles increases when you reach 5th level (2 spears), 11th level (3 spears) and 17th level (4 spears)
