So, having crafted 2000 dungeon tiles as well as a 3200 item undead spreadsheet (seriously, check out the Rourg Campaign and TBD sections), I'm a little tired. This section is shorter than I would have liked, but it cannot be helped, I will increase it as time allows. 600 dungeon segments are currently planned to allow you to lay out entire underground nations in a few short hours, but for the time being, we have 100 floors of the Conjuring Crypts (also known as the Inverse Spires of Spite and Halistars Hell Halls) as well as instructions for a Dungeon Spawning System I developed in my spare time.
I will trust you can add stairs yourselves.
