i only played tabletop rpg once in 3 sessions
so i dont know if thats retarted in this context, but neutral gases slightly heavier than air make neat conundrums
say a seemingly open chamber, with a ramp at entrance, so that its actually a wide concave pool of odorless gas, of 1.2m at deepest height, filled with sulfur hexafluoride

they start to get dizzy, voices with grave timbre, WTF is going on GM?
