This page contains a replica of the Rules Reference found in any copy of the Core Set of Arkham Horror: The Card Game. It also includes updates to the Rules Reference: rules added in deluxe expansions (marked in red) and rules added in the official FAQ for the game (marked in blue).
+As of March 2026, with the release of a new Core Set for 'Chapter Two' of Arkham Horror: The Card Game, Fantasy Flight Games is offering The Arkham Grimoire, "a comprehensive collection of rulings covering all known situations in the game. As a living document, it is maintained online and updated as new cards, rules, and interactions are introduced or discovered." The Arkham Grimoire addresses rules, topics, and questions pertaining to content released in 2026 and beyond. It can be accessed here: The Arkham Grimoire.
+ +As Fantasy Flight Games is maintaining its own living rules document, the maintainers of this page will no longer update this page, considering it a 'final' version of the 'Chapter One' rules for the game (up to February 2026). The retired FAQ document, which pertains to all products released up to March 2026, can be accessed here: FAQ v.2.5 - Legacy Edition.
+ +On individual card pages throughout ArkhamDB you will find rulings. These are taken from the FAQ documents issued by Fantasy Flight Games or direct rulings from the game designers. These individual entries will continue to be updated during 'Chapter Two'. To send in a ruling, please forward any rulings you receive from FFG to arkhamdbfaqs[at]gmail.com and the team will add the ruling to the relevant cards.
+The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents.
