Bone Cage

A rib-cage like dome of bone erupts from the ground, protecting you from harm. Any creatures in the area of effect as the bones burst forth must make a Dexterity saving throw, taking 3d6 piercing on a failed save, or half as much on a successful one. Whether the creatures pass or fail the save, they are all pushed outside of the cage into the nearest unoccupied space.

The area inside the bone cage is considered difficult terrain for anyone other than you, and while you are within the cage you are considered to have half cover from attacks originating outside of it.
