Tyranny of Earth

   You clench a fist toward a creature you can see within range and swing it toward the ground, forcing the target to succeed on a Strength saving throw or fall prone and be unable to stand for the duration.

   If the target would take any bludgeoning damage as a result of falling prone in this way, it instead takes twice as much.

   The target can repeat this saving throw at the end of each of its turns, ending the effect on a success.
