The KeyForge Master Rulebook (MRB) is the comprehensive rules of play for the game of KeyForge. It is the game’s most authoritative source and contains a detailed glossary, official errata, frequently asked questions, and a timing chart. It is primarily a reference document to help players find answers to specific questions. We update this rulebook periodically as new cards sets are released and as new questions arise about how to resolve various card interactions that occur during games.
Note that if you’re new to KeyForge, the best ways to learn how to play the game are to read Learn to Play KeyForge and to watch our video tutorial.
What’s New in Version 17.1?
This is a housekeeping update to the MRB focused on clarifying several cards from Winds of Exchange. It includes a few updated glossary definitions, several new FAQ entries, and errata for two new cards. Let’s take a closer look at these changes.
Five glossary terms received small updates for better clarification: Chain Bidding and Chain Handicap (both optional rules for casual play), Fight, Omega, and Playing Cards.
Of these, the update to Playing Cards is probably the most important one to call out: When you play an upgrade on an opponent’s creature, you still control the upgrade even if the creature to which it is attached remains under the control of your opponent. Note this is not a change to the rules; this is how upgrades have always worked, but it is a rule that can be easy to overlook.
Questions, Questions, So Many Questions
There are new FAQ entries for Gĕzdrutyŏ the Arcane, Rampaging Brutodon, Researcher, and The Promised Blade (all of which are new cards from Winds of Exchange).
