The up stairs to the [[Dungeons of Doom]] will never be in the maze, and [[level teleport]]ing or falling from above will never place you inside it. The down stairs, up stairs to Sokoban, and quest portal may be in the maze. Unlike other layouts, walls are diggable, trees may be chopped down, and iron bars may be dissolved by acid.
