I hope the maniac won?

I bet they figured out the mana user right away and used them as a counterweight to other factions, right?

Regarding online play: the fact that the Confessor can be easily subdued by a Sleeper, and vice versa, in the first night, isn't good; happy coincidences can completely upset the balance.
The Confessor can also simply ask the same question to everyone they subdue: "Who is the master?" and the probability of success will be somewhere around 1 in 4, which is also discouraging.
