It had us terrified. The Warlock was quickly down to just cantrips and begging us to risk a short rest despite the damage we'd all take. The bard was hoarding his spells like they were gemstones. The fighter was tired of always having to be the only guy wading into the thick of battle because nobody else could risk the loss of hit points. The druid was bemoaning having not gone circle of moon for the extra tough wild shapes, while looking at his precious goodberries as if they represented life itself. And all of us were thinking maybe a cleric would have been super helpful right about now. We had a fine discussion about whether the gas would leak into a rope trick...though none of us could cast rope trick so it was a purely theoretical discussion.Ooh. I need to add a section like that to my megadungeon!
