The only thing worse than adversaries attacking you from elevation is when you can't immediately access that elevation yourself. The half-a-level rooms of my dungeon were designed to allow for one room to overlook the room below. Open doorways dropping ten feet to the room below are against fantasy-OSHA regulations, though, so I built some fall protection in the form of a nice protruding balcony.
You like the additional architectural touch of raising the balcony up a bit by adding a flight of access steps? Purely unintentional. When I first built the thing, I measured from the tabletop to the floor, forgetting that this balcony would be resting on the floor of the room below - a full 5mm above the tabletop. Rather than cutting the supports, which would have meant the balcony was just 5mm above the floor, I added the steps to give it a little more vertical difference.
The railing height is pretty good though. Should meet fantasy-OSHA standards of 39 to 42 inches above the ground surface. (Guess who wears the safety hat as part of his day job.)
