If there is an Alchemist-Summoner in play, the game starts with a Demon in play, as normal. If the Alchemist-Summoner chooses a player, they make that player a Demon but do not change their alignment.
If the Summoner is drunk on the 3rd night, the Summoner chooses which Demon, but the Storyteller chooses which player.
If the good team wins with a Heretic in play: eliminate the Heretic.
If the game ends due to the Saint's ability and no other characters were eliminated: eliminate the Saint.
