TEXT: AcAstus Knight Asterius 
  540 points
  Of the gigantic Acastus pattern Knights, some of the largest such war machines still in existence, the Asterius is among the most rare. Like its more common cousin, 
  the Porphyrion, it boasts an armoured hide near impervious to weapons fire, striding across the battlefield like an angry giant beset by insects, and also wields a pair 
  of twin ancient conversion beam cannon. These weapons are irreplaceable relics of a lost technology, each capable of sundering the walls of mighty fortresses and 
  laying low powerful foes in a single blast.

  Household Rank (Questoris only)
  When used as part of the Questoris Knight Crusade army list, the Acastus Knight Asterius is subject 
  to the Household Rank special rule, which may grant it an alteration to its basic profile and additional 
  special rules as shown in the Questoris Knight Crusade Army special rules. This may not be chosen for 
  those of the rank of Scion Aspirant or Scion Uhlan.
  Blessed Autosimulacra (Mechanicum Taghmata only)
  When used as part of a Mechanicum Taghmata army list, the Acastus Knight Asterius has the Blessed 
  Autosimulacra special rule. If it has suffered Hull point damage at the end of the controlling player’s 
  turn, roll a D6. On a 6, one lost Hull point is restored.
  Ion Shield
  When the Knight is deployed, and subsequently at the start of each of the opposing side’s Shooting 
  phases, the Knight’s controlling player must declare which facing each Knight’s ion shield is covering. 
  The choices are front, left side, right side or rear.
  The Knight has a 4+ invulnerable save against all hits on that facing until the start of the opposing side’s 
  next Shooting phase. Its ion shields are repositioned before any attacks are carried out in the Shooting 
  phase and may not be used to make saving throws against close combat attacks.
  Occular Augmetics
  The Knight has the Night Vision special rule, and may re-roll results of a 1 on the Vehicle Damage table 
  and Destroyer Weapon Attack table which are inflicted by their shooting attacks at a range of 12" or less.
  The Acastus Knight Asterius 
  may be taken as a Lords of 
  War choice in a Mechanicum 
  Taghmata or Knights Questoris 
  Crusade army. It may be taken 
  in other armies as an Engine of 
  Destruction and is considered 
  to be included in the Panoply 
  of War list (see page 130-131 
  of the Horus Heresy: Age of 
  Darkness rulebook). If selected 
  as an Engine of Destruction, 
  this model does not gain the 
  Household Rank or the Blessed 
  Autosimulacra special rules.

  Acastus Knight Asterius Weapons  
  Conversion Beam Cannon 
  Among the largest known surviving examples of the rare and delicate conversion beam technology, conversion beam cannon are rightly feared as siege 
  weapons and fortress breakers. These gigantic weapons, when tied to the complex systems concealed within the Acastus Knight Asterius’ carapace, are focussed 
  on a target point while the beams are calibrated and aligned, causing a sub-atomic implosion that literally tears all matter in the target zone apart.

  Karacnos Mortar Battery 
  The Acastus Knight Asterius carries a full battery of hideously effective chem-fire incendiaries; each bomb laced with a deadly cocktail of alchemical poison 
  that burns flesh and ceramite with equal abandon. Such weapons are rightly feared by allies and enemies alike, for they do not simply kill, they taint the very 
  ground for which the armies fight.
