The Rooms are not very clear on many of the Tiles, which can make it difficult to determine where various things Spawn, or come into the dungeon. There are dozens of ways that the rooms could be defined. I have outlined one such way, and I put it up here for use in your games.
I hope that this brings some consistency to our games when determining 'what room' to spawn a boss in etc.
Good Questing To you!
