It has nothing to do with jumps. You're still not actually reading. Do that, please.
No one else has provided anything better. But as I already said to Kirby, if a second flavor scanner claimed that made sense with respect to the action part of Sultan's role, then i would buy both it and Ben, yes.
It is not 15% unless you know that more than half of the 7 stars are on the fakeclaim list. I'm assuming that at least 4 of them are in the game, which gives Ben exactly a 25% chance of finding one star on night 1.
All information from power roles is potentially useless. There's a chance that cop scans a player who dies and then cop has shit, does that mean that cop is worthless?
