Haven't done a mafia in a long time, so I'm in.
One of them is quite characteristic of Las Vegas - the gambler. This role was used a couple of mafias ago, so I decided to use and expand it. There are 6 gamblers in the game - one mafia-aligned, five town-aligned - who, during each nightphase, PM me two players' names, neither of which can be their own. The second player is then told the primary role and element (but not secondary role) of the first. Thanks to the gamblers, there should be plenty of information going around a couple of rounds in, so even if you're just a vanilla tourist, you might well know some important information.
Is the second player fixed or are they randomised? Say, a gambler chooses Alfonso and Benny in his pm (in this order). Is it always Benny who receives the info?
