  WARHAMMER 40,000 – CODEX: DRUKHARI
  WARHAMMER 40,000 
  CODEX: DRUKHARI
  Official Update Version 1.1
  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.
  ERRATA
  Pages 103 and 104 – Talos and Cronos, Keywords
  Add ‘Fly’
  Page 115 – Kabal Obsessions, Slay From the Skies
  Change the penultimate sentence of rules text to read:
  ‘In addition, enemy units do not receive the benefit to 
  their saving throws for being in cover against attacks 
  made by models with this obsession that can Fly, or by 
  models with this obsession that are embarked upon a 
  Transport with this obsession that can Fly.’
  Page 118 – Alliance of Agony
  Add the following sentence:
  ‘You can only use this Stratagem once per battle.’
  Page 120 – Agents of Vect 
  Change the Command Point cost of this Stratagem 
  to 4CP.
  Change the final sentence of this Stratagem to read:
  ‘This Stratagem cannot be used if there are no Kabal 
  of the Black Heart units from your army on the 
  battlefield, and cannot be used to affect Stratagems used 
  ‘before the battle’ or ‘during deployment’.
  Page 125 – Labyrinthine Cunning
  Change the rules text to read:
  ‘Whilst your Warlord is on the battlefield, roll a D6 each 
  time you or your opponent spends a Command Point to 
  use a Stratagem; you gain one Command Point for each 
  roll of 6.’
  FAQs
  Q: The Voidraven Bomber’s Void Mine rule allows you to 
  pick a unit the Voidraven flew over and roll three D6 for each 
  Vehicle or Monster in the unit, or one D6 for ‘every other 
  model in the unit’. Does this mean ‘every other type of model 
  (other than Vehicles or Monsters)’, or ‘every second model’?
  A: It means the former – roll one D6 for every model 
  in the unit that is not a Vehicle or a Monster. So, for 
  example, if the unit contains 10 Infantry models, you 
  would roll ten D6.
  Q: Can the Vexator Mask relic force a charging unit to attack 
  after all other units have done so?
  A: Yes, unless that chosen unit has an ability that allows 
  it to fight first in the Fight phase, in which case it instead 
  fights as if it didn’t have that ability. 
  Q: If a Succubus is given the Serpentin combat drug, does 
  its Weapon Skill characteristic increase to 1+? If so, does the 
  Succubus still hit if a hit roll of 2 is rolled for an attack for a 
  melee weapon and, due to an ability, I have to subtract 1 from 
  that hit roll? 
  A: Yes, and yes – only unmodified hit rolls of 1 
  automatically fail. 
  Q: If the only Kabal of the Black Heart unit in my 
  battle-forged army is in an Auxiliary Support Detachment, but 
  my army includes another Drukhari Detachment that is not 
  an Auxiliary Support Detachment, can I still use the Agents of 
  Vect Stratagem?
  A: Yes, so long as the Kabal of the Black Heart unit 
  is on the battlefield.
  Q: If a model is slain by an ossefactor, and the mortal wound 
  inflicted by the ossefactor’s ability causes another model in that 
  unit to be slain, do I roll again to see if another mortal wound 
  is inflicted?
  A: No.  
  Q: If I am playing a matched play organised event that has 
  an upper limit of 3 Detachments per Battle-forged army, what 
  is the maximum number of Drukhari Patrol Detachments I 
  can include?
  A: 3.
  Whilst the Raiding Force ability in Codex: Drukhari 
  mentions Battle-forged armies of 6 or more 
  Detachments, this is designed for narrative play games, 
  or for matched play games with larger (or no) limits on 
  the number of Detachments you can include in your 
  Battle-forged armies. Note that the guidelines provided 
  for organised events in the Warhammer 40,000 rulebook 
  are just that, and the event organiser may wish to modify 
  these guidelines to best suit their event’s needs.
