I should have written that yes, the CULTIST is certainly dead - or near-death! But the intent is to allow movement to an adjacent chamber of your choice without having to roll 2d6 CATACOMB CONFUSION.
And yes! I have often thought about making a video playthrough/instruction - as well as a major overhaul of the rules with some help from outside designers. I'd love to make a video, but I currently don't have a camera - or haven't learned how to use my phone to get decent film - still using an old 2013 model. But yes that's something I would love to do eventually!
