Wrath of Terra

You conjure two enormous stone Hands to rise from the ground, closing in on a 40 ft area of your choice. All creatures must make a dexterity saving throw. On a failed save, the targets take 10d12 bludgeoning damage  and the targets are also restrained. On a successful one the targets take half as much damage. As an action, the creatures can make a strength saving throw DC16 to break free.
