You create a tiny ghostly, pointed bone that is shot at a creature within range. This ranged spell attack ignores any AC bonuses from three quarters cover and below.  On a hit, the target takes 1d10 piercing damage.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
