The night started with the group recovering after a random encounter from the week before. They headed to the Alchemical Laboratory and from there promptly attacked by the Dryder (it was fantastic fun) the encounter took some time as only one player had a ranged weapon they could attack with, and the wizard hesitant to use spells in anticipation for the battle to come. The group consists of Inquisitor/Monk crossbow build, fighter/wizard/edritch knight melee, Witch Debuff master, and Druid who runs around as a wolf (so does his companion) Anyway after a few rounds of cambat and a few lightning bolts from the Dryder later this is where the silly begins. I have been a player for close to 7 years and this is my first time as DM. My number one rule is to have fun no matter what happens and that DND/Pathfinder is 100% about the players and their story. That being said... I described the buildings before they encountered the Dryder, The ruines of what looked like 3 domed buildings, one left in tact. They asked me if there were any windows or openings from the dome that was intact, I replayed No. The only openings they could see was the Chimney like structure letting all the noxious gas escape. After the Dryder fight the druid and his companion were stacked on the door and the witch was flying atop the building (a magic item he has) I was asked again if there were windows or any other openings, again I replied that only the door and the chimney thing. Then Aden told me this "I walk over to the chimney and stuff my bed roll into it blocking the noxious gas from escaping". I paled visitable as I thought it over in my head... The encounter behind the door was over before it began... All I could do was laugh. The monsters behind the door were trapped as they couldn't move the door to escape
All I can say is looking at this after the fact their were measures as a DM I could have taken to prevent the loss however... I had to give it to them, It was brilliant
