Bio Shards

You harden and weaponize bits of your anatomy (such as feathers, scales, claws, nails, etc.) launching them as projectiles.  Roll a ranged spell attack.  On a hit the target takes 1d8 damage (work out which type with your DM, based on what body part you use).  You can add your STR mod to the damage per damage dice rolled, at the expense of -2 HP also per dice rolled.

This spell increases at 5th (2d8), 11th (3d8), and 17th (4d8) level.
