The Reaper wins when all players are dead, unaligned or sleepless. For each player that dies, the Reaper may use a power to turn another player sleepless.

The Reaper starts out sleepless and shares a channel with other members of the nightmare team. At the start of every night, the Reaper will be informed of which powers they may use that night. These powers correspond to the role categories of the players who have died since the start of the previous night. For each Killing role that has died, the Reaper may turn one player sleepless and attack them. For each Investigative role that has died, the Reaper may turn one player sleepless and investigate their role. For each Power role that has died, the Reaper may turn one player sleepless and nullify their public voting power for as long as that player is sleepless. For all other roles that have died, the Reaper may turn one player sleepless.

The Reaper is not told which role category the dead players belonged to: they are only informed of which powers (kills, investigations, vote nulifications, and basic powers) are available to them. If the Reaper chooses not to use one of their powers during the night, they lose that instance of the power. Sleepless players are not informed of their being sleepless: however, if a sleepless player uses an ability other than targeting on the Reaper, their ability fails and the Reaper immediately attacks them. The Reaper is affected by all disguises and redirections when using their powers. They gain powers solely based on the true roles of those who have died. If no members of the nightmare team or channel remain, the sleepless effect is silently removed from all players.
