Мафия 23. The Rockland tavern

I don't understand what the point of the Brewer is. He can protect against the only block in the game, but at the same time, he can prevent four useful abilities for the city from being implemented. He will send "I'm not going anywhere" every night.

This line introduces even more confusion: 2) if the player to whom the Brewer came is killed, the Brewer himself remains alive, but does not see the killer due to his intoxicated state;

The Thief only provides a clue for the killer he exposed.

And, if it's not difficult, could you somehow separate the descriptions of the roles, with all the important points marked in bold – the names of the factions, the names of the characters, a list of their properties.
