Designate a target location for the deployment of a large mechanical claw. The device will fly to that location and deploy the claw, which will unfurl into a huge claw structure, taking up a 400-square-foot area. All creatures within the area of the mechanical claw at the start of their turn must make a STR saving throw. Upon a failure, the creature takes 4d8 force damage and they are knocked prone. Upon a success, they take half damage and remain standing.   On your turn, you may use a bonus action to direct the mechanical claw to move to another location 30 feet from its current location. It must still be within the range of the device controlling it. If you move the mechanical claw into the space of another creature, it must immediately make the STR saving throw and take damage as normal.
