Also, if someone is levitiating or flying in the room, we could have some sort of trap that guards against that as well. Like, spikes on the ceiling that only would allow people to walk noramally through the room....or...if the trap goes off in the room and the person is flying, then they are 'sucked out through a long tube-like corridor and spit out onto the overworld some random distance from the castle'
