Bones of the Earth

Cause up to six stone pillars to burst from ground within range. Each is 5 ft. in diameter and up to 30 ft. high. A creature in a pillar’s space must make a DEX save or be lifted. If blocked by a ceiling or obstacle, the creature takes 21 (6d6) bludgeoning damage and is restrained until it escapes with a STR or DEX check against your power save DC.
