If there is a rule called “Ghost”, then append the following text to that rule:

If the haunted target of a ghost is a werewolf, and the ghost has haunted that target for at least a day, then once during each consecutive nighttime period of haunting, there is a 1 in 5 chance (as determined by the mayor) that the ghost will witness the villager transform into a werewolf, in which case the Mayor shall privately communicate that to the ghost.

If there is a sub-rule called “Werewolf Prisoners,” then remove that sub-rule.

Add a new sub-rule to 2.3 (Werewolves) called “Werewolf Prisoners”:

During any nightime period, if a living werewolf has an occupation of prisoner, then the Night Watchman, and each of the villagers who possess a set of Gaol Keys, each (assuming their status is Alive) have a 1 in 6 chance to witness the villager transform into a werewolf, as determined by the Mayor, who will notify the werewolf and each witness of the results.
