The Inquisitor is adept at consulting the Emperor's Tarot to reveal the course of the future, and can gain valuable insights into the outcome of a coming battle. Both players roll a dice before deployment. If the dice rolls are different, the Daemonhunters player gets +1 on the dice roll to ascertain who goes first. If the dice rolls are the same, he suffers -1 to the roll. One per army.
