Sheriff

Mechanics

 * You will know if your target is a Werewolf, but only during a full moon.
 * You cannot find Detection Immune roles (Godfather, Arsonist, Vampire, Neutral Evil roles, and the Werewolf during a night without a full moon).
 * If your target was framed in the same night, they will show up as a member of the Mafia.
 * If your target is a Disguiser, they will show up as a member of the Mafia, no matter which role or person they may have disguised as.

Strategy

 * Unlike the Investigator, you can only directly determine whether your target is suspicious or not, and not just their possible roles. Sharing information and discussing with the Investigator will allow you to narrow the pool of suspects:
 * If the Investigator finds a possibly suspicious role (e.g. a Doctor, Serial Killer or Disguiser), you should interrogate that person to prove their guilt or innocence.
 * If the Investigator finds a certain Town member (by process of elimination), you will not need to interrogate that person.
 * If the Investigator finds a full detection immune role list (e.g. a Bodyguard, Godfather or Arsonist), you will not need to interrogate that person either because they will all appear the same.
 * If the Investigator finds a Framer, Vampire or Jester, you should put doubt on your interrogation results, since your target may have been framed.


 * If you're lucky enough to find the Serial Killer or a member of the Mafia early in the game, it would be best to stay silent and keep it in your Will until about Day 3 or 4. The Town will likely think you are an Executioner if you accuse someone anytime before then because this is a common strategy authors use.
 * If you suspect a player of being the Werewolf, remember to check on a full moon. Otherwise, they will appear as a Townie or another Detection Immune role.


 * Careful, multiple roles have Detection Immunity, such as the Arsonist, and will appear as "not suspicious". Beware of whom you trust!
 * At any given time, there can only be one Godfather. Therefore, when a Godfather dies, anyone you investigated up until (and including) that night who came up Not Suspicious cannot be a member of the Mafia. Note that they could still be an Arsonist, Witch, or Vampire; and people you investigate after the Godfather's death could be a Mafioso who has been promoted to the Godfather.


 * Careful, framed players will appear to be a member of the Mafia, so never be too quick to judge who is evil or not. If you aren't sure, check the same person the next night. If the Framer does not frame the same target again, your results will change. There are some Framers that will frame the same target for a few nights in a row, so it's very hard to know if your information is true or not. However, in ranked, if the random Mafia is dead or known to not be framer, it is safe to accuse anyone that shows up as Mafia. The chance of there being a Framer is low enough that the risk is worth it.


 * If a Witch controls you, you will be forced to check a different target without knowing who it is. Hopefully, the Witch will reveal their actions in their will, so then you can find out who you were forced to interrogate the night you were controlled.
 * If a Transporter transports your target, you will interrogate someone else entirely! If the Transporter reveals his or her will, you will know who you interrogated that night! But if you see that you were controlled or if your target says they were transported the next day, then don't trust the information that you have been given as it is most likely false. This can make the game very confusing.
 * Don't reveal your role to the Town too early, and don't accuse someone if they came up as Mafia right off the bat. Instead, wait a little longer, which gives you more time to find other evil roles and keep yourself anonymous. Accusing too early or sometimes the wrong person can cause players to think you are an Executioner or even a Consigliere who found a Neutral Killing role. Always accuse when you have enough info, and don't reveal too late either, as doing that when important Town roles are dead will mean nothing.
 * If you are certain the only roles left are detection immune roles, such as Godfather and Arsonist, don't give up! If people trust you, you can direct the town. It is safe to not visit anyone though, because you could run into a Veteran.
