I'm sure this is covered somewhere,(it's in the rules from what I recall, I can't find 'em at the moment) but what exactly is the difference between retired investigators and those that were devoured in final battle, and when can investigators choose to retire?
Also, does the number of successes required to remove doom tokens from the AO's sheet during final battle decrease as investigators are devoured? I've always played it that it does not decrease. So, for instance if in a three-players game, if one investigator is devoured during the AO fight, the remaining players will still need to roll three successes to remove a single doom token. What made me doubt this is one of those special gate encounters that pits you against an Ancient One, This particular one is a dual-colored blue/yellow encounter that puts you versus Shub-Niggurath. It says: since there's only one player in this combat, you only need one success to remove a doom token.
