Mastermind

If the Demon dies by execution (ending the game), play for 1 more day. If a player is then executed, their team loses.

The tentacles of that monster are nailed to the doors of the church. Mothers and children are dancing in the street. Excellent. Everything is proceeding exactly as I have planned.

Jinxes

Alchemist

An Alchemist-Mastermind has no Mastermind ability and the Mastermind is not-in-play.

Al-Hadikhia

If the Al-Hadikhia dies by execution, and the Mastermind is alive, the Al-Hadikhia chooses 3 good players tonight: if all 3 choose to live, evil wins. Otherwise, good wins.

Lleech

If the Mastermind is alive and the Lleech host dies by execution, the Lleech lives but loses their ability.

Vigormortis

A Mastermind that has their ability keeps it if the Vigormortis dies.

How to run it (Storyteller)

When the Demon is executed and the game would normally end, announce that play continues for one more day and proceed to a new nomination phase — do not reveal why unless players figure it out. The nastiest ruling: if no execution occurs on the bonus day (players choose not to nominate or all nominations fail), the game simply ends with evil losing, so do not let the day drag indefinitely. Watch for the Al-Hadikhia edge case: if that Demon is executed and the Mastermind is alive, you must privately offer the Al-Hadikhia's three-player choice tonight before resolving the bonus day.

How to play

  • Your win condition is a legal execution on the bonus day — it does not matter who is executed, so your job is to make sure the town executes someone when they think they've already won.
  • Stay alive at all costs; a dead Mastermind loses the ability entirely, so you are the evil team's most valuable asset to protect, often more important than the Demon itself.
  • Coordinate with your Demon before the game: agree on a scenario where the Demon can afford to be executed while you are still alive, turning a town victory into a loss.
  • Claim a passive or hard-to-check good role — Scholar, Farmer, or a role that would naturally survive to late game — so the town has little incentive to execute you before or during the bonus day.
  • On the bonus day, create maximum confusion: remind players of nothing, let chaos drive a nomination, and if needed subtly push for an execution of a good player by casting doubt on whoever the town trusts most.
  • The most common mistake is being too visible as a strategic threat; if the town suspects a Mastermind is in play, they will refuse to execute on the bonus day entirely, so blend in and never telegraph your role.

How to fight the Mastermind

  • If the Demon dies by execution and the game does not immediately end, a Mastermind is almost certainly in play — immediately call for a moratorium on nominations and pressure the group to pass the day without executing anyone, since no execution means evil loses.
  • Track who has been least threatened by the town across the entire game; the Mastermind tends to be a quiet, low-profile player who has avoided heat, because dying removes their ability.
  • Before executing the Demon candidate, confirm you can also identify and execute the Mastermind — if you can kill both on the same day or the Mastermind is already dead, the bonus day is neutralised.
  • On the bonus day, the burden is on good to simply do nothing; abstaining from all executions is a guaranteed win, so only execute if you are certain you are executing the Mastermind themselves.
  • Be aware that a living Mastermind changes the Al-Hadikhia's execution outcome dramatically — if Al-Hadikhia is the Demon, killing them while the Mastermind lives triggers a different resolution, so identifying the Mastermind before executing the Demon is critical in that script.

Key interactions

Al-Hadikhia

Executing the Al-Hadikhia while the Mastermind is alive does not trigger the normal bonus day; instead it shifts into the Al-Hadikhia's three-choice night mechanic, so good must kill the Mastermind first or accept that executing this Demon opens a second path to an evil win.

Lleech

If the Lleech's host is executed while the Mastermind is alive, the Lleech survives but loses their ability — this can be a hidden benefit for good, stripping the Lleech, but evil may exploit the confusion of a 'dead' Demon who is actually still in play.

Vigormortis

A Mastermind retains their ability even after the Vigormortis dies, meaning the bonus-day threat persists beyond the Demon's death — good cannot assume the Mastermind is defanged just because the Vigormortis is gone.

Alchemist

An Alchemist who receives the Mastermind ability gains nothing functional because the Alchemist-Mastermind has no ability and there is no real Mastermind in play, so the Mastermind's bonus day can never trigger in that game.
