You can cause a swarm of skeletal arms to burst from the ground to rip and tear your foes. The skeletal arms erupt from the ground in a 20-foot-radius burst. Anyone in this area takes 2d6 slashing damage. Those caught in the area receive a Breath save for half damage. Those who fail the save are unable to move for 1 round. The skeletal arms are spectral and disappear after 1 round. The arms must burst up from a solid surface. You can use this ability once per day. This power has a range of 60 feet.
