This Greater Mystery may only be cast upon a mortal, unblessed Champion or Warleader. It grants them temporary great reserves of strength to be used to shake the earth. The empowered Champion or Warleader may, once only, during an Arena battle, call MASS STRIKEDOWN by slamming his weapon into the ground. Poseidon's trident will strike the earth and rock it; all those unprepared will be thrown from their feet.
