To clear up the wording confusion. Disregard "perfect immortal". It has been changed
Regarding the Lesser Grand Panaceea:
"After drinking the elixir, if the player dies via anything other than a lynch, a strongman kill, or a Rail Tracer kill, then the player shows up dead as “Immortal”, revives the next day (after a day and a night phase), and loses their lesser immortality. This effect does not stack."
Regarding the Rail Tracer sacrifices:
"A player (with or without a group) or multiple players in the same group (masons, mafias, or TP teams) can beckon to the Rail Tracer to perform one of three actions on a specified player"

So I expect at least 2 killing parties, possibly 2 mafia teams because surprisingly enough we haven't had that in a while and the size allows it. 4 each perhaps. And I really believe it'd make sense to add a Santa given the time of the year + how well that TP fits in with a 2-mafia setup, + gifts could tie into the mechanic. Just some pointless thoughts for now.
