Inspiring Presence The Ethereal and all Tau units (not Kroot, Vespid, or drones) with line of sight to him may re-roll any Morale checks. This includes passed Morale checks. The re-rolled result stands. Any If the Night Fighting rules are in use then roll to determine the distance the unit can see. Any Tau unit joined by an Ethereal caste member becomes Fearless.
Price of Failure If a friendly Ethereal is removed as a casualty then every Tau unit on the table (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. Every unit that takes the test gains the Preferred Enemy universal special rule in relation to the enemy army. This applies whether the Morale test is passed or failed, and lasts until the end of the game.
