Filch's triple-wield is also nice if you can get the weapons to do it.
Yeah, in our game there was a few times where we cheated that one. If a room went singularly badly for us, we set everything back to the way it was at the start and tried again, rather than restarting the adventure...
I'm always Maginos! The right upgrades and a bit of luck and he can just clear the room.
(Though due to group membership I've played Nez, Maginos, and on occasion Filch. Maybe the others once. Never played Collin, one of the other regulars had him.)
