  WARHAMMER 40,000 
  CODEX: DEATH GUARD
  Official Update Version 1.0
  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.

  FAQs
  Q: For the purposes of the Psychic Focus matched play rule, 
  is the Miasma of Pestilence psychic power from Codex: 
  Chaos Space Marines the same psychic power as in Codex: 
  Death Guard?
  A: Yes. More generally, if psychic powers have the same 
  name, they are the same psychic power for the purposes 
  of Psychic Focus.
  Q: If my army is led by a Chaos Space Marines Warlord, and 
  I have a Detachment of Death Guard, can I use the Gifts of 
  Decay Death Guard Stratagem to include a Relic on a Death 
  Guard Character?
  A: Yes. The only requirement to have access to 
  Stratagems is that you have a Detachment of the 
  appropriate Faction. If you have a Death Guard 
  Detachment, you have access to their Stratagems. 
  Q: Is it possible to use a Stratagem from Codex: Chaos Space 
  Marines to target a unit from Codex: Death Guard? For 
  example, can I use the Tide of Traitors Stratagem on a unit of 
  Cultists from a Death Guard Detachment if I have an Alpha 
  Legion Detachment and a Death Guard Detachment in a single 
  Battle-forged army?
  A: Yes – if you have access to a Stratagem because you 
  have an appropriate Detachment, it can be used on 
  any permitted target: they do not need to be from 
  that Detachment. In your example, the Alpha Legion 
  Detachment gives access to the Chaos Space Marine 
  Stratagems, and Tide of Traitors can be used on any 
  Chaos Cultists – this would include any Chaos Cultists 
  from the Death Guard Detachment.
  Q: Can Poxwalkers use the Curse of the Walking Pox ability to 
  increase the unit above its starting strength? 
  A: Yes.
  Q: If the Poxwalkers’ Curse of the Walking Pox ability 
  increases the unit above its starting strength, does this cost 
  reinforcement points?
  A: No.
  Q: Are the Biologus Putrifier’s hyper blight grenades affected by 
  his Blight Racks ability?
  A: No.
