At the start of each player turn, the player whose turn it is can choose one of their characters within 6" of the Nehekharan Sphynx to challenge the spirit to a riddling contest. The challenger must take an Initiative test. If the test is failed, the model suffers a Wound which Ignores Armour Saves. If the test is passed, the challenger receives one of the following special rules, determined randomly, for the rest of the game: Devastating Charge, Heroic Killing Blow or Loremaster (Death) – the latter has no effect on non-Wizards.
