Vampire Hunter

Basics

 * If there is a Vampire Hunter at the start of the game, there will always be at least one.
 * Vampire Hunter is not a unique role.
 * You can visit other players at night. If your target is a Vampire, you will kill them.
 * Visiting the same target the Vampire goes to on the same night will not lead to the youngest Vampire nor the target being staked by a Vampire Hunter.
 * If a Vampire visits you at night, you will not be turned into a Vampire, but instead you will be notified of their visit and you will attack them, killing the Vampire.
 * If roleblocked and visited by a Vampire, you will still attack the Vampire.
 * If you visit a vampire on the same night that they visit you, they will be listed as killed by a Vampire Hunter twice.
 * You can hear Vampire chat at night. You will hear it even if you are dead.
 * If a is protecting a Vampire, the Bodyguard will kill you if you attack the Vampire.

Turning into Vigilante

 * Once all Vampires are dead, you will become a Vigilante.
 * You will only have 1 bullet instead of 3.
 * The transformation is irreversible. You will not turn back into a Vampire Hunter if an remembers a Vampire role.
 * If you were an Amnesiac and become a Vampire Hunter after all Vampires are dead, you will not turn into a Vigilante.

Strategy

 * If you become a vigilante, follow the strategies on the Vigilante page.
 * However, there are a few tricks unique to Vampire Hunters turned Vigilantes. In particular, if anyone else claims Vampire Hunter, press them on whether there are any Vampires left alive; if they don't know or say that there are, they're lying about their role and you should probably shoot them (and write this in your will, since they're possibly an immune Godfather.)
 * Check down the list, then if you end up checking every check them again, they might have been turned since you checked them, perhaps even as you were checking them.
 * If Vampires are talking, pay attention to what they are saying. Vampires may lie to fool you; however, they're somewhat less likely to do this than the Mafia is to a spy, since the worst they can generally accomplish is making you waste your visits.
 * If they mention that someone is immune to bite, it's most likely true. Write it down in your will, but remember that calling them out reveals you as well.
 * If the Vampires argue over who to convert or discuss their victims, this can often reveal who they've turned into a vampire. This is a much more common mistake than you would think, since Vampires need to vote on who to convert.  Pay attention to what they say; even if they don't name exact names, you can often figure out what they're arguing over based on context.
 * Try to figure out talking Vampires comparing their writing style to that of players in day chat. Pay attention to the usage of emoticons, word capitalization, spelling etc.
 * If Vampires stop talking after several nights of discussions, it may mean that there is only one Vampire left.
 * Try to figure out who the vampires are most likely to turn and focus your visits on them.
 * Look over the list of people to convert on the Vampire page, and follow that yourself when deciding who to investigate.
 * Vampires can only convert non-Mafia, non-Night Immune, non-Witch roles. If you suspect someone falls into any of these categories, skip them. Even if it's not true, they're less likely to be Vampires, since the Vampires will probably have reached the same conclusion as you and avoided visiting them.
 * Anyone who was confirmed as Town, however, is a possible Vampire, especially if they have an important role.
 * Jesters and Survivors are frequent targets for Vampires, since they're convertible and unlikely to be protected.
 * If a Mayor has only one vote, this means they've been turned into a Vampire (however, in this case, the Town will often notice and lynch them for you.) Conversely, as long as the Mayor has three votes, they are not a vampire.
 * A Survivor or Bodyguard's bulletproof vest provides no protection from Vampires. If someone claims to have vested against a Vampire attack, they're lying.
 * Pay particular attention to the wills of Lookouts. Anyone who was visited by a confirmed vampire may have been turned into a vampire.  (And if you are certain the visit was when the visitor was already a vampire, and they weren't turned into a vampire themselves, then they are likely evil and should be called out.)
 * Try and bait Vampires in:
 * "I hate my role, can Vampires turn me?" sometimes works although experienced players may suspect you to be a vampire hunter, in which case they are less likely to attempt to bite you.
 * Claiming Survivor or acting like a Jester can occasionally lure the vampires into trying to bite you; however, it carries a high risk of getting you lynched by the Town, executed by a Jailor, or shot by a Vigilante. Therefore, this is best saved until near the end of the game when it's possible evil roles are near a majority.
 * Claiming Survivor near the very last night (ideally at the very end of the day when there's not enough time for you to be lynched) can sometimes swing a Town victory by luring the Vampires to attack you while making the Mafia ignore you and target the Vampires instead, hopefully turning you into a Vigilante in time to swing the game with your final bullet.
 * A Bodyguard will kill you (and you will kill them) if you visit a vampire they're protecting; however, in this case, whoever you were trying to stake is confirmed as a vampire. Always list your visits in your will, especially your most recent one, so people will know who the vampire is in that situation.
 * Vampire Hunters only exist in games with vampires. Therefore, if you get this role, there must be a Vampire in the game somewhere.
 * Vampire Hunter is not unique, if a Vampire Hunter is dead and you have to say your role and people claim it's unique, these people have a high chance of being Vampires. Check them as soon as possible!
 * When you become a Vigilante, consider not revealing this fact until you use your bullet. While Vampire Hunter is unharmful to everyone but Vampire, a Vigilante presents a direct threat to Mafia and Witch, both of which will hunt for you as soon as they know your new role. You may not want to shoot right away, so it's better to lull scums into thinking you are still Vampire Hunter. However, if Consigliere or Investigator checked you and it became public, shoot the next night.


 * Remember that your ultimate goal is for the Town to win, not simply to kill the Vampires. This means that under some circumstances (when you need the Vampires' votes in order to keep the Mafia from getting a majority), you might be better off waiting to kill confirmed Vampires.
