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.
The Summoner cannot create an in-play Demon. If the Summoner creates a not-in-play Demon, deaths tonight are arbitrary.
If the Summoner is drunk on the 3rd night, the Summoner chooses which Demon, but the Storyteller chooses which player.
If the Engineer removes a Summoner from play before that Summoner uses their ability, the Summoner uses their ability immediately.
The Summoner cannot create an in-play Demon. If the Summoner creates a not-in-play Demon, deaths tonight are arbitrary.
The Kazali can choose that the Soldier player is one of their evil Minions.
If the game ends due to the Saint's ability and no other characters were eliminated: eliminate the Saint.
