You are the Arsonist. You are a third-party faction with your own win condition: Fiery doom for all! You win when all other players are sealed or dead without hope of revival. You do not have to be living to reach this win condition.
Your abilities are:
Faction Passive: Burning Vengeance: While dead or fakedeathed*, the Arsonist may triple the amount of targets he chooses for his abilities.
Prime: The arsonist may douse someone in an accelerant each night. That player will be informed that they have been primed -- priming on a living player lasts until the target dies. Alternatively, the Arsonist may choose to prime a dead player to incinerate their body when ignited. Priming on a dead player lasts 3 rounds. May not be used in the same round as Ignite.
Ignite: Ignite all primed targets, killing them if they are living, and sealing them if they are dead. May not be used in the same round as Prime. This ability may not be used while dead.
Flicker: Investigate the role of a target player. While dead, this ability cannot be used in the same round as Prime.
From the Ashes: If the Arsonist dies, once per game he may choose to revive himself with the “Reborn” revive type within 3 rounds. Use of Flicker while alive is permanently disabled after he is revived.
*Fakedeath: A fakedeathed player will appear publicly as dead and may not vote, but will be able to use actions. The next round, they will be revived with the “Restore” revive type. Certain roles have the ability to induce this state.
In the kill order the first two were mine.
