Mid-Game Reference

Unique Classes
Remember that even if a class is not Unique, there is a limit of at most two people of each class at the start of the game. The only exception to this rule is the Blue Dragon's classes that have a limit of three non-unique starting classes.

Night Action Order
The order of night actions is as follows (with a few exceptions):
 * 1) Occupation, Redirection, and Guarding
 * 2) Attacks
 * 3) Healing
 * 4) Investigative Abilities
 * 5) Conversion

Advice for Evil Killers
As Assassin, Cult Leader, or Neutral Killer, it may sometimes be better to actually not attack, not bleed, and not poison, and instead hope that your opponents execute each other during the day. This is especially useful if you are the last evil killer alive in the game, since poisoning, bleeding, or attacking someone who gets healed might do nothing but confirm the victim and his healer as innocent. Eventually, after enough time without deaths, people may execute the king under suspicion that he is the last scum remaining. You may also frame jailed players in this way, encouraging Prince to execute an innocent person and lose his executions.

If you are getting desperate, consider claiming to have been poisoned or bled in order to buy yourself another night without suspicion.

If you kill the King Night 4 or later, you might be able to win yourself a lot of trust by claiming to be a Butler who poisoned him. This is especially effective if you leave a deathnote corroborating this claim. Unfortunately, if King was Good, the court will know you are evil when you survive the next night.

Scum Reading
People who ask the King whether to execute or pardon are often scum trying to deflect responsibility to His Majesty and gain His favor at the same time.

Contrast what could have reasonably been expected to result from a player's decisions with the actual outcome. Generally, judging a player based on the former is a more reliable indicator of their intentions.

Refusing to vote up an evil is often a better indicator of guilt than whether they ultimately voted to execute, pardon or abstain.

Especially in the very late-game, be very cautious about hopping on a voting bandwagon. You might put an innocent player on trial and not be able to pardon him. In some situations, getting accused by too many players can actually prove a person's innocence. For instance, in a 3 v 3 where you are Blue Dragon, and assuming scum don't vote up their own teammates, anyone who gets enough votes to be put on trial must be innocent.

Someone who was previously leading the investigation but becomes suddenly quiet is likely converted.

"Meta" (IRL) excuses are usually low-attempt lies. For example, "Sorry I didn't post my logs because I had a phone call."

If someone is aggresively defending someone (A.K.A white knighting) and the person who got executed flipped as Unseen/Cult, then most likely the person who defended them are their scum buddy.

Fake-Claiming Healer
Consider publicly claiming that someone unsuccessfully attempted to poison or bleed you, in order to bolster your credibility. This is because real healers (Alchemists and Physicians) are immune to such effects, and the evil faction cannot target one of their own with poison and bleed.

If you're fake-claiming Alchemist as an evil, asking for King's faction in a whisper can improve your credibility, since genuine Alchemists often do this. Bonus points if you promise not to rat him out if he admits to being evil. If King makes a suspicious mistake but continues to claim Blue Dragon, slyly inquire (in whisper of course) if he's sure he's not evil (even if you know he's Good).

What to claim when playing against The Princess
When dealing with The Princess, you'll want to claim a class that is of the same type that you are. You should avoid claiming a Unique class, as if there is really one, you will be known to be a fake. If you're converted and it's convenient for you, you can continue to claim the class you were before you were converted.

The types that a Princess can find you to be are:

Support/Social
The following claims are suitable for Alchemists, Mercenaries, Apostles, Illusionists and Ritualists. (Classes in italics are neutral, and may prove to be a weaker claim if you aren't that class)
 * Physician
 * Court Wizard
 * Noble
 * Mystic
 * Mercenary
 * Alchemist

Special/Investigative
The following claims are suitable for The Mastermind, The Cult Leader & Seekers.
 * Princess
 * Sheriff
 * Paladin
 * Observer

Killer/Offensive
The following claims are suitable for The Assassin, Invokers, The Possessor, The Reaper, The Sellsword and The Sorcerer.
 * Butler
 * Drunk
 * Knight
 * Hunter (Unique)

Type Change When Converted
When playing as one of these classes, it is important to choose a different class to claim as, so that a Princess doesn't find out you are converted.
 * Knight: Becomes Support/Social group once converted.
 * Physician: Becomes Killer/Offensive group once converted

Additionally, these are the results that The Princess receives when using Flirt.

Effects provided by The Court Wizard's Empower
The Court Wizard's Empower ability can assist with the following positive effects:
 * Empowering a Support class will make the class immune from all occupation/preventions/redirection attempts so immune from Butler Serve, Drunk Happy-hour, Prince jailed prevention, Mercenary Stand Guard, and Sellsword Stone-wall or Intimidate.
 * Empowering an Offensive class will make the class gain death immunity for the night.
 * Empowering an Investigative class will make your target always see "true results" this means that they will be immune to Apostle/Illusionist Mindwarp, Aristocrat Intrigue, Scorned Frame, and Fool Deceive.
 * Empowering a Social class will make them conversion immune for the night.
 * Empowering a Killer class will make their attacks unhealable. (The Hunter's wolf will still be healable)
 * Empowering a Special class will have no effect.

Classes who appear as Magic Users to The Inquisitor

 * The Court Wizard
 * The Sage
 * The Paladin
 * The Mystic
 * The Illusionist
 * The Sage
 * The Sorcerer
 * All members of the Cult
 * The Sorcerer's day ability Magic Dust causes all players too appear as Magic Users that night

Troll Box Strategies
The Troll Box is an ability both The Scorned and The Fool have which allows you to make another player appear to say something of your choice. They will not know they said it. The following are some strategies for using the Troll Box.

Meta Troll Box
A "Meta" Troll Box is a use of the Troll Box ability to make someone appear to say something about Troll Box itself. For example, The Scorned might Troll Box one of their targets at the end of the day into saying, "Bleeding, please heal", and the next morning again into saying, "I was trollboxed, I wasn't bleeding." Since one cannot actually see their own trollboxes, the target will seem as if they were lying in both instances.

Fake Troll Box
A "Fake" Troll Box is something said by a player intended to appear as if it were a Troll Box. For example, a member of The Cult put on trial after being investigated by a Paladin might inject an out-of-place admission of guilt in the middle of their actual defense, with the aim of convincing the court that they are a target of a Scorned. To illustrate: The middle line appears to be an actual use of Troll Box, painting the accused as an innocent victim. This strategy is most effective if the fake trollbox line is prewritten and copied beforehand then pasted immediately after another line has been posted.
 * Cult Leader: "I am a physician, I healed 9 last night!"
 * Cult Leader: "I'm guilty just exe me I don't care anymore"
 * Cult Leader: "If you execute me, you will lose the only healer you have left."

You can frame someone as Scorned after the execution of a Blue Dragon member by saying something like, "Hi, I'm 5. I'm Scorned.  That was one of my targets.  Thanks for the win!", just as the day ends, so they don't have a chance to respond.

Obvious Troll Box
If you are attacked during the night, you may post an obvious trollbox on the King in order to communicate your identity to your attacker and hope that they help you achieve your goal. An example of a Fool trollboxing the King in this way:
 * "TROLLBOX: I'm Fool and I was attacked last night. Please don't kill me at night.  Help me get executed during the day!"
