Bloodborne Mafia Topic 7: An Honest Death is the Only Cure

Protection:
Bodyguard
Weak JK

Scanning:
Watcher
"cop"?

You can kinda put weak JK into the scanning role too, but they are either a protection who cannot protect town power (though they can stop town anti-power from dying, heyo!) or a very weak scanner who can only confirm that someone stayed put or not. Which only works if he gets everyone on record day 1 as being able to more or not move at night, so scum team let themselves get played into making corrik a more formidable scanner than he otherwise would have been.

And then a backup.

If the Vigi and potentially the neighborizer as well are scum then that's honestly not too much power
