  WARHAMMER 40,000 – THE EDGE OF SILENCE
  THE EDGE OF SILENCE
  Indomitus Version 1.1
  These documents collect amendments to the rules and present 
  our responses to players’ frequently asked questions. Often 
  these amendments are updates necessitated by new releases or 
  community feedback; these can be identified by the presence 
  of an asterisk before the page reference. At other times, these 
  amendments are errata designed to correct mistakes or add 
  clarity to a rule that is not as clear as it might be. 
  As they’re revised regularly, each of these documents has a 
  version number; where a version number has a letter, e.g. 1.1a, 
  this means it has had a local amendment, only in that language, 
  to clarify a translation issue or other minor correction. When 
  a document is revised, the version number will be incremented 
  and new updates will be highlighted in blue, while new errata 
  and FAQs will be highlighted in magenta.
  UPDATES & ERRATA
  Designer’s Note: When we wrote Edge of Silence, we created 
  some new rules for the relic shield and storm shield. When used in 
  isolation – say, when playing through the missions in Edge of Silence 
  – these rules work perfectly well, but when used with a Battle-forged 
  army, it is possible to upgrade a Character with Artificer Armour, 
  and in doing so have a model with a Save characteristic of 1+. This 
  was not our intention, and so we are changing the rules for both 
  these items of wargear as they appear on these datasheets. 
  Please also note that while some abilities, weapons and other 
  items of wargear (e.g. storm shields) for the Space Marines and 
  Necrons datasheets in this booklet appear in other places with 
  slightly different rules, the rules for them that appear in Edge of 
  Silence should not apply to other units – you should continue to 
  use the rules as printed in your current Codex for the time being. 
  Page 16 – Primaris Captain, Other Wargear, relic 
  shield, Abilities
  Change this to read:
  ‘Add 1 to armour saving throws made for the bearer. In addition, 
  each time the bearer would lose a wound as the result of a 
  mortal wound, roll one D6: on a 4+, that wound is not lost.’
  Page 16 – Primaris Lieutenant, Other Wargear, storm 
  shield, Abilities
  Change this to read:
  ‘The bearer has a 4+ invulnerable save. In addition, add 1 to 
  armour saving throws made for the bearer.’
  Page 18 – Bladeguard Veteran Squad, Other Wargear, storm 
  shield, Abilities
  Change this to read:
  ‘The bearer has a 4+ invulnerable save. In addition, add 1 to 
  armour saving throws made for the bearer.’
  The <Chapter> Keyword
  Indomitus has been released and the forces of the Adeptus 
  Astartes have been reinforced. On the datasheets for the new 
  miniatures within The Edge of Silence, there is the <Chapter> 
  Faction keyword, meaning these units belong to Space Marine 
  Chapters from Codex: Space Marines. You can, however, take 
  these units as part of another Space Marine Chapter not found 
  within that publication. To do so, replace the <Chapter> 
  keyword in every instance on that unit’s datasheet with Blood 
  Angels (or the keyword of a Blood Angels successor Chapter, e.g. 
  Flesh Tearers), Dark Angels (or the keyword of a Dark Angels 
  successor Chapter, e.g. Angels of Absolution), Deathwatch 
  or Space Wolves. For example, if you include an Assault 
  Intercessors unit and you decide it is from the Blood Angels 
  Chapter, its keyword becomes Blood Angels.
