I expect scum not to sell their abilities, i expect townies to do it if they believe they will die that night or if they believe that ability would synergize better with another townie's set of abilities.
Also, im like 100% sure that there will be abilities that create night PMs or neighbor chats.
The ability to have your own division will help with the selling of abilities too, especially in that division manages to clear themselves.
Then it becomes a ''mafia pm'' but for townies.
It then becomes really important to vote people into captain positions that have a good eye for finding and discerning scum early, so as not to have them recruit scum.
Also i expect alteast one of the ''Captains'' to be scum, given that scum will coordinate better for voting a single person, they will vote one of theirs into that position.
So be wary of the Captains.
