That ability sounds incredibly OP but alrightReading up on this but in the mean time here have this tidbit of information.
I am Gardenia. My role allows me to once per game, at night, investigate three different Roman numerals and see if there any of them are anti town. I used this last night on inffy, purple, and notme so I can say they are all town sided players as I received the result of false (I would get true if any of them were anti town).
Now obviously one of them might be godfather but I'm willing to take my chances are hope they aren't.
