Auspex Bafflers Knight Banners included in a Dominus Battleforce maniple cannot benefit from obscuring cover (see the Adeptus Titanicus rulebook). If a Knight Banner from a Dominus Battleforce maniple is wholly within 6" of a Titan from the same maniple (i.e., all Knights from the Banner are within 6" of the Titan), and both the Titan and at least one Knight from that Banner is visible to the attacker, attacks made against the Titan from more than 2" away from the Titan suffer a -1 modifier to the Hit roll.
Noble Sacrifice When a Titan in a Dominus Battleforce maniple takes a hit from an attack originating from more than 2" away from the Titan, it may transfer the hit to any Knight model from the same maniple within 6", as long as that model is visible to the attacker – you must transfer the hit before making any Armour rolls. The chosen Knight suffers the full effects of the hit as if it had been the original target. If the hit was from a weapon with the Blast trait, centre the Blast marker over the Knight. Hits from weapons with the Firestorm or Beam traits may not be transferred in this way.
