Each night, the Horseman of Pestilence may doom a player. Too sick to act, any attempt of that player to use an ability during that night and following day will fail.

Dooming a player is an immediate effect. For the rest of the night and the following day, any attempts to use an ability will fail for that player (this includes automatic uses of powers such as Huntress's attack). This also applies for group actions, should the doomed player be chosen to execute it. For some abilities, this may be indistinguishable from other failures (attacks), while others have no other way of failing (investigations). Completely passive abilities, like Runner, as well as the ability to whisper, are not affected. When the Horseman of Pestilence attempts to doom another Horseman, it fails: the two Horsemen unite, joining a shared channel. Doomed players are informed that they have been doomed, but not which Horseman doomed them. Doomed players can be doomed again by the same or a different Horseman. Dooming and its accompanying effect persist even if the Horseman of Pestilence dies, but immediately disappear when no Horsemen remain.

When all remaining Horsemen are united and all remaining players doomed, Doomsday is unleashed: the Horseman of Pestilence turns into an Apocalyptic Horseman, with the ability to attack a player each night. The Horsemen win when everyone else is dead.

Each night, the Horseman of Death may doom a player. The Horseman marks the player, and they will die at the end of the following night.

Dooming a player is an immediate effect. Players doomed by the Horseman of Death will die at the end of the next night (this is not an attack). When the Horseman of Death attempts to doom another Horseman, it fails: the two Horsemen unite, joining a shared channel. Doomed players are informed that they have been doomed, but not which Horseman doomed them. Doomed players can be doomed again by the same or a different Horseman. Dooming and its accompanying effect persist even if the Horseman of Death dies, but immediately disappear when no Horsemen remain. When all remaining Horsemen are united and all remaining players doomed, Doomsday is unleashed: the Horseman of Death turns into an Apocalyptic Horseman, with the ability to attack a player each night. The Horsemen win when everyone else is dead.

Each night, the Horseman of War may doom a player. There is no time for elections whilst war is raging: during the next day they will lose their vote and cannot be elected.

Dooming a player is an immediate effect. The public vote of players doomed by the Horseman of War will not count during the day after their dooming, and should they win the election poll, the election fails and nobody is elected. When the Horseman of War attempts to doom another Horseman, it fails: the two Horsemen unite, joining a shared channel. Doomed players are informed that they have been doomed, but not which Horseman doomed them. Doomed players can be doomed again by the same or a different Horseman. Dooming and its associated effect persist even if the Horseman of War dies, but immediately disappear when no Horsemen remain. When all remaining Horsemen are united and all remaining players doomed, Doomsday is unleashed: the Horseman of War turns into an Apocalyptic Horseman, with the ability to attack a player each night. The Horsemen win when everyone else is dead.

Each night, the Horseman of Famine may doom a player. Doomed by the Horseman of Famine, they are starved, becoming unrecognizable. Instead, they will permanently be seen as a horseman role.

Dooming a player is an immediate effect. Players doomed by the Horseman of Famine will be permanently and strongly disguised as an arbitrary in-play Horseman role (one that existed when Night 1 starts). When the Horseman of Famine attempts to doom another Horseman, it fails: the two Horsemen unite, joining a shared channel. Doomed players are informed that they have been doomed, but not which Horseman doomed them. Doomed players can be doomed again by the same or a different Horseman. Dooming and its accompanying effect persist even if the Horseman of Famine dies, but immediately disappear when no Horsemen remain. When all remaining Horsemen are united and all remaining players doomed, Doomsday is unleashed: the Horseman of Famine turns into an Apocalyptic Horseman, with the ability to attack a player each night. The Horsemen win when everyone else is dead.
