This extremely powerful Greater Mystery can be cast only on an arena battle during the Saturday of the Final Annual. Casting must be complete a half-hour before the arena battle and the city or cities which are the target of the battle must be in Pisces. This Greater Mystery prevents any named Divine Champion or Warleader, N'Hru, Ghul, Ifrit, Demigod, Immortal man, Man of Bronze, Lamia, Lich or Lycanthrope from participating in the arena battle. Instead, they may enter the next arena battle which their nation is participating in, either attack or defence, irrespective of whether their warband is fighting. This mystery applies equally to both sides of the combat.
