Investigator

Mechanics
When investigating someone, the Investigator receives a notification depending on the target's role.

Here are the roles that are tied together and the message when investigating them:


 * ,, or - Your target is skilled at disrupting others.
 * ,, or - Your target has sensitive information to reveal.
 * , or  - Your target is waiting for the perfect moment to strike.
 * , or  - Your target owns weapons.
 * , or  - Your target sticks to the shadows.
 * , or  - Your target knows your darkest secrets.
 * , or  -  Your target is covered in blood.
 * , or  - Your target is not afraid to get their hands dirty.
 * ,, or - Your target works with dead bodies.
 * , or  - Your target keeps to themselves.
 * , or  - Your target may not be what they seem. (Note: You will also receive this message if your target was framed)

Surviving as an Investigator

 * Always consider if it's worth exposing yourself as a Investigator. Once other players know you are an Investigator, you will become a target. But if you know that you have Town Protective roles, revealing yourself as Investigator early and giving everyone information about suspicious bad guys can help Town win.
 * Make sure to do your best not to reveal who the Townies are, as you could end up making them a target for kill-capable Mafia and Neutral Killing. However, simply posting that someone is good may lead experienced evil players to conclude that the said person is important (e.g. you put that someone is a confirmed townie.


 * Doing the math for a given Role List can give the Investigator a much greater insight. Take Ranked Mode and the result 'Medium/Janitor/Retributionist' as example: (Ignoring Any, as it has neglectable influence, and assuming the Retributionist has already been identified) Janitor can only appear as Random Mafia, as 1 of 7 roles, with 14%. Medium can occur as one of the Town Supports. There are 5 Support roles, so on the first role there is a 80% chance that there is no Medium. If the 'locked role' was Mayor or Retributionist, the next slot has a 75% chance of not being Medium (3/4), otherwise a 80% (4/5). This results in a total chance of 62% of 'two not-Mediums', aka 38% for '1 or 2 mediums'. If you now take the 14% of Janitor and the 38% for Medium, and scale them up to a sum of 100%, you get the exact chance that an investigated Janitor/Medium is role X. In this case, its 26% for said person to be a Janitor and 74% for said person to be a Medium. Note that his values are exclusively correct the moment you get the investigation result on N1. Every single revealed role changes the ratios (i.e. if a target is cleaned, the chance for a Janitor in the game raises from 17 to 100, turning the investigation odds to 60% Janitor/40% Medium).
 * A less complicated and precise version of the math strategy is simply counting the kinds of roles left and seeing which has a higher probability. For example, if someone is "Escort/Transporter/Consort". However, both Town Support roles has been already dead. Thus, there is a higher chance the person is Mafia since the slot of being Escort or Transporter in the Random Town slot and Any slot is much smaller. However, beware that the townies you accuse of being evil might be actually filling the Random Town and Any slot.


 * The Investigator is much more powerful in Classic Mode due to not all the roles being available. If you, for instance, get the Lookout / Forger / Amnesiac result, then they are a Lookout, as only the Lookout is available in Classic Mode. Use this to your advantage to ensure your survival and the cohesion of the town's votes and kills by forming a whisper network.
 * Always investigate people who claim roles. Many Godfathers like to pose as Executioners, Jesters or Sheriffs...


 * If there is a Sheriff - work together. At daytime, discuss with each other about who you are both going to visit. At night, both of you choose the same person. For example, if the Sheriff's investigation says your target is not suspicious and yours says that they are the Doctor, Disguiser or Serial Killer, that person is definitely a Doctor.
 * However, this can backfire, as a Transporter, Witch, Escort, Consort, or Jailor can interrupt your plan. Also if you both visit a Veteran on alert, both of you will die.
 * This could be a waste of time in some games, because there won't be many leads for the following time, but it does work and is doable.
 * Because there may be Consigliere in the game, the Mafia can try to trick real Investigators to make townies think they are Consigliere instead. To avoid this, make sure you wrote your will properly and in the exact order of your investigation result. Writing investigation results in a different order may lead townies to think you are a poorly-played Consigliere.
 * Write the best will you can. You can make or break a game depending on your will. Consider leaving out important roles though, as the mafia will probably target them the second they get their hands on your will.
 * If you receive a result with possible good and bad roles, try to ask the person their role. For example, if you received "Your target owns weapons. They could be a Vigilante,Veteran or Mafioso." ask the person their role. If they say a role you didn't get, for example, escort or refuse to reveal, they might be a Mafioso. However do not let this be the be-all to end-all, as they may be hiding because they will be killed if they speak too much.
 * You should write down any claims people make about their roles, and investigate them later; catching someone lying about their role is an easy way to determine that they're evil.

Dealing with Investigator Results

 * Even if you find a Mafia or Neutral Killing on Night one, don't immediately tell Town about it. Claims on the first two days make anyone seem like an Executioner, and even if you manage to hang the player, the Mafia or Serial Killer will try to attack you as soon as possible, preventing you from discovering more. It is best to wait, writing everything in your Will and whispering to known Townies. You can decide to reveal yourself on Day 3 or later, but a Day 2 reveal is generally unwise.
 * Janitors can be the downfall of an Investigator since they wipe out wills, revealing them only to the mafia (or possibly the Spy). If this is a threat to you, try to find good roles. Finding a Spy or a protector and whispering your findings to them will allow the Town to retain your findings after you being cleaned, if the person you whisper to is trusted by the other Townies. This works especially well with Jailors; an informed Jailor is a lethal one.


 * If a player you investigated could be both good or bad (e.g. Medium/Janitor/Retributionist), sometimes it may be worth it to ask them for their role. If they claim a role that isn't what you got or refuse to give you this info, then they are likely the evil role of the 2 or 3. However, if they are evil and survive the day, you are most likely dead. Make sure to include in your Will that they are evil, if this does occur.


 * Remember to record the roles people have "claimed" in your Will, not just what you discover through your investigation; catching lies is one of your main roles. Under most circumstances, Town members have no reason to lie about their roles.


 * Someone appeared to be "Vigilante, Veteran, or Mafioso"? Take account if there was any death by Vigilante or Veteran. If there wasn't, the person is a Mafioso or a Vigilante who decided to just shoot people with enough proof. Also, most games (Classic Mode and Ranked) just have one Town Killing, so if there is a known Veteran, it's easy to see the Mafioso.
 * If there's no Mafioso in the Graveyard, and Godfather dies, investigate that player again. If their results don't change, they're a proven townie to you. If their results changes, it's obvious they're Godfather after recently being promoted.


 * If someone is shown as "Framer, Vampire or Jester", remember that they might be framed. If you're unsure, you can visit them later to see if you get the same result.
 * However, know that sometimes the Framer will frame the same person throughout the entire game.
 * Framed people always come up as Mafia to a Sheriff. Therefore, if a Sheriff investigates someone and finds them not suspicious the same night that you investigate them and get a result of "Framer, Vampire, Jester", then they must be a Vampire or Jester; they cannot have been framed.
 * If it's impossible for there to be a Framer, it is dangerous for the Town to lynch them, since they might be a Jester. However, a Jailor or Vigilante can bypass this by executing or shooting them; provided it's impossible for there to be a Framer, there's no risk of them being a Town member.
