- Each night, the Arsonist is given the option to either douse a player's house with gasoline or set a doused house on fire.

- If the owner of the house chooses to leave their house (visits and Watchers) during the night the Arsonist sets their house aflame, they will avoid being killed by the fire.
- Players who choose to not leave their house (i.e., no visit) on the night of dousing or any subsequent nights will be able to notice if their house is doused in gasoline and receive a report telling them: "At night, you pick up the distinct smell of gasoline around your house".
- Drivers and Doctor saves are not affected by the Arsonist's fire.
