non-rectangular stairs in dungeons
I want to make a dungeon map that consists of dug out tunnels and small caves, where not all caves and tunnels are on the same level. For example, there could be a short flight of stairs in the middle of a tunnel that leads to a dungeon part, which lies 1 or 2 meters below the rest of the dungeon. Or in some caves there might be some kind of irregularly formed raised area.
Those stairs should look a if they were hewn out of the stone and they shouldn't be all that regular/symetric.
How would I paint this in Dungeon Designer? So far I have only found typical dungeon stairs that are made of single bricks/stones and they have the typical square shape.
It sould look something like this sketch.
