The Dealer is the shopkeeper and you can, uh, provoke them by not purchasing anything! If that happens, he can APPEAR next floor with a GUN, whereas you can collect his INFO!! (you can also do this by taking a picture of him at his shop)
WHAT I didn't EXPECT is for there to be TWO DEALERS on the next FLOOR afterwards.. 😨😨
anyways enjoy the video I'm as stumped as you are LOL. I hate NVIDIA I need a new recording software
