🤣 Back in the days of 3.5, I was the only one in the party with knowledge of dungenering. I RP'd a ditzy elf and would roll my d20 to make choices. I rolled and ended up staying at the mouth of the dungeon while the rest of the party went inside.

The wizard had kegs of infinite gun powder. The rogue "emptied" the kegs and put in booze. ... The eventual resulting explosion collapsed the dungeon, destroyed the town on top of it, and only my elf survived because she didn't go in.
