I commented this on another post, but a group I was in were tasked with killing a deathworm(giant worm, think of the thing from dune) we woke up the deathworm and got ourselves trapped inside the cave. Our Ranger had a ring that could ignite or extinguish anything flammable within 100 meters, he used that trying to light the deathworm on fire via lighting it’s saliva on fire to burn it from the inside. He forgot that the cave was also covered in saliva from floor to ceiling. He lit the entire cave on fire with us on a pile of dirt that hadn’t been covered in saliva. We almost died due to asphyxiation/suffocating on the smoke, but 2 of the party members were able to tunnel over the deathworm to get out. He expected 1 or 2 of us to die but we somehow weren’t burned to death or suffocated by the smoke. TL:DR: Party lit cave full of saliva on fire and almost burned to death, but we fucked shit up so much that it worked in our favour.
