Price of Failure
(Rule)Description: If a friendly Ethereal is killed then every unit of Tau on the tabletop (not Kroot, Vespids or Drones) must take a Morale check at the start of their next turn if they are not in close combat or falling back. In addition, every Tau unit that takes the test will benefit from the Preferred Enemy universal special rule, with the enemy as their preferred enemy. This applies whether the Morale test is passed or failed, and lasts until the end of the game.
