Normal proposals I've found here and weren't suggested by me that I think could be Normal, and my thoughts on them:
Vain - Possibly a good idea I think? We have both Loyal and Disloyal.
Publishing - Seemingly good idea, but only works for investigative roles and might work strangely for Checkers. I feel this doesn't detract heavily from Normals, however this would necessarily cause the moderator to post information in the game thread. Also note that Publishing Informed can exist!
X-Result - The generalization of a X-Shot modifier that only depletes on a specific type of investigation result. If the greylist comes back, this would easily be on the greylist.
Gutless - Somewhat interesting, but would make Doctor interesting. This was originally suggested by creating a wiki page and saying the modifier was Normal, however.
Here is a post with some other Normal proposals, though I'm thinking Cursed isn't normal.
In post 919, DDynamo wrote:Informant Role: Targets a player to make them informed of a detail of the setup. Basically the Mailman, but the message you send is predetermined by the Moderator and unknown to the player.
Charging Modifier: A further modifier to X-Shot. Charging makes it so you get charges back for events that occur in the game, such as a Cop that gets a charge every time a Town Power role is eliminated at day.
Skimmer Role: If the Skimmer visits the same target as the Doctor, the Skimmer gets protected as well.
Famous Modifier: The existence, but not alignment, of the full role of the player is announced by the moderator at the beginning of the game.
X-Result Modifier: A role that only consumes charges if the role receives a certain result, such as a Cop that's only allowed one guilty result before the role ceases to function. That would be created in a game read as "1-Guilty Cop".
Cursed Modifier: Your role will only work on other players who are also Cursed.
Obsessive Modifier: Opposite of Roaming Modifier, if you target a player you must continue to try to target that player every night until they die, at which point you're free to change.
Thaumaturge is a role I've invented and really should see discussion before being Normalized, though I consider a Thaumaturge to be a
Neapolitan variant with its checkerboarded results seeming like they would make the role interesting especially if there are role claims.
