I am a completely noob! Haddock explained me some things...
Could you please share with me what kind of power players can have?
I know only mods have that information but maybe you have an idea about Mafia games in general.
Some common ones...
Doctor - protect someone from a NK (Town Role)
Cop - Find out if someone is Mafia or not (Town Role)
RB - Block someone's action (Town or Scum Role)
Redirector - Redirect Action from A to B (Town or Scum Role)
Rolecop - find out what power someone has (Town or Scum Role)
Vigilante - Town who can kill someone at night (Town Role)
Bulletproof - passive power, survives one kill (Usually Town Role)
Commuter - can go away at night, isn't affected by anything (Usually Town Role)
Neighborizer - create a private chat with someone else (Town or Scum Role)
Godfather - Passive; if targeted by the Cop he gets an innocent result (Scum Role)
And then there are the two prominent 3d party roles who are neither Town nor Mafia, which are
Survivor - Wins if the is alive at the end of the game
SK - wins if everyone else is dead.
Beyond this, we shouldn't talk about roles yet. The setup is closed, we literally have no idea what is in this game
