Divulgence
a player. If you scumread a player, you of course want to either Departure them or Divulgence them. Between the two options, I think that Divulgence is almost always superior, for the same reasons that a Public Cop is so powerful – you're in some sense forcing the mafia NK. If the person that you Divulgence is indeed scum then it's true that you have to sort of waste another day phase actually eliminating that player, but if the person you choose is town then you eventually either force the mafia to NK that person, or allow that person to live to LyLo, where an IC changes the EV for town pretty significantly. If you townread a player, it might seem like choosing Erudition or Supplement is a good idea, but it seems like whoever you give the power to just immediately gets killed by the Mafia. So you've wasted a day phase where you could otherwise be eliminating someone / revealing someone's alignment and instead allowed the most townread person to die – in essence, it seems identical to voting "no elim".
I would imagine that the fact that it's always optimal to divulgence until you hit scum (at which you depart them) probably runs contrary to your vision of how this setup should play out. So maybe it would be interesting if you could choose any number of the options in a single day, from one to all four. Of course, doing all four might make it too townsided, so perhaps the more options that you choose in a day, the more powers that scum get to counterbalance it. Might be an interesting direction to go in.
