Serial Killer

Serial Killer Aliases: Cannibal Psychopath Alignment: Serial Killer Role type: Killing Third-party Choice: Night Status: Regular Normal

A Serial Killer is a player whose goal is to be the last player alive. They are aligned with themselves (meaning they have no allies) and have a factional kill at Night like the Mafia. Depending on the flavor, SKs may also be called Cannibals, Psychopaths, or Arsonists (note that Arsonist has since grown to describe a unique role).

Normal version

This role is allowed in Regular Normal games.

Serial Killers are allowed in Large Regular Normal and Mini Complex Normal games but it must be announced that a Serial Killer exists. Serial Killers are allowed in Large Complex Normal games without needing to announce that a Serial Killer exists.

The Normal variant of a Serial Killer is as a self-aligned third party with no additional powers, other than a night kill. Other roles or modifiers can be added, however, but they are considered separate roles that are part of the role name and need to be shown when the SK flips.

A Serial Killer's kill is considered factional, so if investigated by a Role Cop or Vanilla Cop, SKs (with no further powers) should return a "Vanilla" result. Serial Killers traditionally kill with knives, so show up as not having a gun to a Gunsmith investigation - note that all deaths should still have the same generic Kill Flavor.

The presence of a Serial Killer can often keep a game going even at numbers that would normally lead another faction to win immediately (e.g. 1 Town, 1 Mafia, 1 Serial Killer going into the Night). As a general guideline, if a Serial Killer is still alive, the game should not be called over unless the Serial Killer has won or some groupscum faction controls more than half the votes in the game.

Variations

Serial Killer is the most difficult standard faction to win as, since being the sole survivor requires the player to dodge all of the Town's eliminations and the Mafia's Night-kills. Thus, they are generally given a boost of some kind, depending on the game.

• Serial Killers are often awarded the win if all players die, typically done by wording the win condition akin to "you win when all other players are dead, whether you are alive or not".
• Serial Killers are often given One-Shot or unlimited Bulletproof. This stymies attempts to kill the SK by the Mafia or Vigs, if temporarily.
• Serial Killers have also been seen with investigation immunity like Godfathers, or Tracker/Watcher immunity like Ninjas.

Occasionally, moderators will include a Psychiatrist that can "cure" SKs, allowing them to win via the Town win condition instead; however, it is almost never used.

In very complex games, Serial Killers can be complex roles unto themselves that just happen to have a factional kill and a self-aligned win condition.

Use & Balance

The Serial Killer exists to ratchet up the death count per Night and raise the swing of the game tremendously due to the SK's independent motivation. These are somewhat desirable in fairly stable Large games, but in role madness or smaller games SKs tend to lead to uncomfortable situations where their actions play a disproportionate role in deciding the game. This can be mitigated somewhat by including a Vigilante instead.

Play Advice

If you draw Serial Killer, do not claim NK-Immune Miller Vig. Although since that meme has appeared, some moderators actually have included that very role in their setups...

Nonetheless, you are usually best off not claiming to be a Vigilante if you are a Serial Killer unless you are incriminated by a Tracker or Watcher result. The basic problem with this fairly obvious claim is that this not only makes you a magnet for other killing roles (including anti-town killing roles), it also gives the town a roadmap for working out what has happened once all the Mafia are dead, and locks you into primarily killing scummy players (if you kill townish players, the town may grow suspicious). If you claim some other role, the town may deduce that there is a Serial Killer but not know who it is; but this is more preferable for you than letting the town know who would be the Serial Killer if one existed (even if you manage to hide the existence of a Serial Killer for a while).
