  WARHAMMER 40,000 – CODEX: ADEPTUS MECHANICUS
  WARHAMMER 40,000 
  CODEX: ADEPTUS MECHANICUS
  Official Update Version 1.3
  Although we strive to ensure that our rules are perfect, 
  sometimes mistakes do creep in, or the intent of a rule 
  isn’t as clear as it might be. These documents collect 
  amendments to the rules and present our responses to 
  players’ frequently asked questions. As they’re updated 
  regularly, each has a version number; when changes 
  are made, the version number will be updated, and any 
  changes from the previous version will be highlighted 
  in magenta. Where a version number has a letter, 
  e.g. 1.1a, this means it has had a local update, only in 
  that language, to clarify a translation issue or other 
  minor correction.

  enemy Infantry and Swarm models, though it must 
  end its move more than 1" from any enemy units. In 
  addition, this model can move and fire Heavy weapons 
  without suffering the penalty to its hit rolls. Finally, this 
  model only gains a bonus to its save for being in cover if 
  at least half of the model is obscured from the firer.’

  unit’s invulnerable save is improved by 1 (to a maximum 
  of 4+).’

  within 9" of any enemy models. If both players have 
  units that can move before the first turn begins, the 
  player who is taking the first turn moves their units first. 
  Each unit can only be selected for this Stratagem once 
  per battle.’

  FAQs
  Q: Do I need to spend reinforcement points to return units when 
  using the Fresh Converts Stratagem?
  A: No.
  Q: If you have a Detachment which receives the Mars forge 
  world dogma, and another Detachment which receives a 
  different forge world dogma, what happens when rolling for 
  Canticles of the Omnissiah? With Mars’ dogma you roll two dice 
  when determining Canticles and units with that dogma benefit 
  from both results, but what happens for the other Detachment?
  A: In such cases you would roll dice separately for the 
  Canticles, rather than rolling for both together. The first 
  Canticle rolled for would apply to all of your units with 
  the Canticles of the Omnissiah ability, while the second 
  would apply only to those units in Mars Detachments.
  Q: When is the Litany of the Electromancer Canticle resolved?
  A: Immediately – i.e. at the start of the battle round 
  when the Canticle is chosen/rolled for.
  Q: Does a weapon that ignores cover ignore the benefit bestowed 
  by the Shroudpsalm Canticle?
  A: Yes.
  Q: Can the Refusal to Yield dogma be used to prevent a unit 
  from being slain due to a 1 being rolled to hit when it uses its 
  plasma weapon?
  A: Yes.
  Q: How do the Chorister Technis Warlord Trait and Glory to 
  the Omnissiah dogma interact – when do I re-roll the first dice?
  A: Roll the first dice, then (if you wish) re-roll it. Then 
  roll the second dice.
  Q: How do the Gloria Mechanicus Stratagem and Glory to the 
  Omnissiah dogma interact – which Canticle can you change 
  with this Stratagem?
  A: Choose one Canticle to change.
  Q: When using the Binharic Override Stratagem, when do the 
  new Battle Protocols you choose come into effect?
  A: Immediately.
  Q: When using the Cognis Overwatch Stratagem, do I apply 
  any relevant modifiers to the firing model’s Ballistic Skill?
  A: Yes, as long as the weapon is a cognis weapon. Note 
  that modifiers to hit rolls do not apply.
  Q: When using the Monitor Malevolus Warlord Trait, can 
  you re-roll a dice that determines how many mortal wounds 
  are inflicted on an enemy unit (i.e. is this classed as a 
  damage roll?)
  A: No, such a roll is not classed as a damage roll.
  Q: Does the Static Psalm-code Warlord Trait affect the range of 
  the Master of Machines ability?
  A: No.
  Q: How does the Rage of the Machines Stratagem work with a 
  Vehicle unit that consists of more than one model?
  A: One Vehicle model from that unit would gain the 
  benefit of that Stratagem. 
  Q: If a Questor Mechanicus unit from your army is 
  selected as the target of the Knight of the Cog Stratagem, must 
  every unit in that Questor Mechanicus unit’s Detachment 
  also have the Canticles of the Omnissiah ability in order for that 
  Questor Mechanicus unit to benefit from it?
  A: No.
  Q: At what point does the invulnerable save of Fulgurite 
  Electro-Priests get increased as a result of the Siphoned 
  Vigour ability?
  A: When the last model of the enemy unit is slain and 
  removed from the battlefield. 
  Q: Can a Graia model that has the Refusal to Yield ability 
  also make use of rules that allow them to ignore lost wounds, 
  such as Fanatical Devotion?
  A: No.
