For context we were wandering around looking for this Hag and we found some sort of tunnel. Our group has no sense of self preservation, so we ignored the weird plant monsters telling us to turn back and went on in.

It was pitch black, nobody could see, not even with dark vision.

Em (aka Me): I have a tinder box, right? I light a match.

DM: You don’t see anything, you can’t even see the light from the match.

Jack, who’s usually quiet: This isn’t your everyday darkness…

Group, in unison: THIS IS ADVANCED DARKNESS!!!!
