Role: The Blackmailer
Role type: Spacial/killer depends on balancing
The Blackmailer is a role that uses a slower approach to the game, it lacks abilities for mass killings like Sorcerer and Reaper, but makes up for it, by blending in deeper into the court than any other NK.
Undying determination - Your list for power gives you the resolve to survive most attacks, you are Death Immune
Background check - Choose a player, you will gain his role and logs when the night starts. (3 uses)
Blackmail - Choose a player that you previously, that player will not be able to talk or use abilities for the rest of the day, instead you will be able to talk for them (and use their abilities?) (2 uses)
Dirty Work - Attack a player (if target is killed, the ability goes on cooldown for 1 night).
Deadly Threat - Choose a player that is not part of the Cultseen and is not Prince, that player will receive your name, number, role (and logs?), and his win condition will change to "Live to see the Blackmailed win the game.
Your convert will keep his role and abilities, but will no longer be able to win with his previous win condition.
You will be able to converse at night. (like Cultseen chat)
(1 - 2 uses depends on balancing, if the ability has 2 uses, it can only be used again after the first ally has been killed).
I think this role will make the game far slower and more interesting, players will get much more time, since the NK only kills 1 player in 2 nights, but he will also have an ally (which could a killer himself, or an heavily trusted BD member like mystic), that will keep him confirmed and allot harder to find.
Right now finding the Mafia can be intriguing, where you would sometimes find roles like Servant or Alcoholic, based on their behavior or night actions, but NKs usually remain pretty simple, while a veteran in the game would be able to fake advanced claims with NK, majority of NKs rely on the good ol’ Knight claim (which always gets them killed instantly), so instead, this is an NK, that can practically claim anything, since there is an ally who would confirm anything, and the only way to find him, would either be by finding that there are 2 players who side together too closely, or finding the actions of one of them too odd.
