Rules

•The entire season will be played on Standard difficulty.
•The entire season will be played on Taboo List 2.5 (February 20, 2026).
•Matches will be as seeded as possible while still allowing for some traditional Arkham randomness. An example of this is that in Wages of Sin, each team will get the same four heretics, but their locations will be randomized. The same will be true for locations.
•There will be a two-hour time limit for round-robin matches.
•Although the season is played on standalone mode, decks will not follow standalone deckbuilding rules. Decks will feature one basic weakness for each investigator, ignoring the rules for XP thresholds.
•As opposed to rolling random basic weaknesses, each investigator will have a fixed basic weakness.
•If the chat or commentator notice any rule infractions while a match is happening, the commentator will step in to correct that
infraction in a way that seems reasonable compared to the infraction.
