Bone Trap

A pair of Small skeletal crocodilian jaws spring from the ground at a point of your choosing within range. Any creature that is within their area when they first appear must make a Dexterity save against your spell save DC or take 2d4 Piercing damage and have the Restrained condition until the spell ends. On a success. they take half damage and are not Restrained, and the spell ends. They repeat this save at the start of each of their turns, except the ability used becomes Strength - They also only take 1d4 piercing damage on a failed save.
