Bone throw

You can make up to four sharp bones float behind you in a spinning circle, the bones face forward from the user. The bones are 3'0 Ft of length. Each bone hits a creature of your choice that you can see within range. One bone does 1d4 + 2 piercing damage. The bones all strike simultaneously, and you can direct them to hit one creature or several. You can not stack the bones.

Once you hit character level 10 you can use 4 more bones, and 4 more at level 20. The new bones are placed in a spaced out spinning circle behind the original spinning circle.
