Yesterday during a normal random dungeon, namely Spindleclutch 11. The group had just finished killing Blood Spawn, we ran up the steps to proceed and as we entered the tunnel instant death? Running back down the steps and trying to go forward again instant death! Die move forward past the entrance to the tunnel all ok, was like an invisible force field that instantly killed all the team.
"No *** lady! does it sound like I'm ordering pizza?"
