If a friendly HIVE TYRANT is killed within 6" of this unit, from the end of that turn each Tyrant Guard's Attacks characteristic is increased by 1 for the rest of the battle.
Shieldwall:
Roll a dice each time a friendly HIVE TYRANT loses a wound whilst they are within 3" of this unit; on a 2+ a model from this unit can intercept that hit - the Hive Tyrant does not lose a wound but this unit suffers a mortal wound.
Instinctive Behaviour:
Unless a unit with this ability is within 24" of any friendly Synapse unit, you must subtract 1 from any hit rolls made for it when shooting any target other than the nearest visible enemy unit, and you must subtract 2 from its charge roll if it declares a charge against any unit other than the nearest enemy unit.
