Pteraxii Skystalkers

During the Declare Battle Formations step, if every model in a unit has this ability, you can set it up in Reserves instead of setting it up on the battlefield. If you do, in the Reinforcements step of one of your Movement phases you can set up this unit anywhere on the battlefield that is more than 9" horizontally away from all enemy models.

If a unit with the Deep Strike ability arrives from Strategic Reserves, the controlling player can choose for that unit to be set up either using the rules for Strategic Reserves or using the Deep Strike ability.

At the start of the battle round, you can select one of the Doctrina Imperatives below. Until the end of the battle round, that Doctrina Imperative is active for your army, and all units from your army that have the Doctrina Imperatives ability gain the relevant abilities shown below.

PROTECTOR IMPERATIVE

■ Each time a melee attack targets this unit, if this unit has the Battleline keyword and/or it is within 6" of one or more friendly Adeptus Mechanicus Battleline units, subtract 1 from the Hit roll.

CONQUEROR IMPERATIVE
■ Ranged weapons equipped by models in this unit have the [ASSAULT] ability.
