This section contains the official errata that have been made to individual cards in KeyForge. Errata overrides the printed information on the card it applies to.
All abilites that begin with “Fight:” should read “After Fight:”. This does not change the timing of when such abilities resolve. The errata has been made for clarity about the proper timing.
All abilites that begin with “Reap:” should read “After Reap:”. This does not change the timing of when such abilities resolve. The errata has been made for clarity about the proper timing.
