Yesterday's post elicited a comment which inspired me to finally comb through my custom bestiary and make a proper OD&D style random Monster level determination procedure. Such a dice rolling convention is used not only for Wandering Monsters, but more importantly for randomly determined initial fills and restocking steps. In case you aren't familiar with the guide in Vol. III of the LBB, here's a scan of pages 10 and 11:
And here is a scan of the two-page custom guide I have fashioned for my new megadungeon. I suppose I am letting the cat out of the bag a bit early, but yes The Bleak Beyond, my current project, is a new megadungeon. It is the bastard child of the Dismal Depths and Ulin-Uthor, the Dim Expanse. Here's the custom version scanned:
The above guide uses my custom bestiary, itself an updated version of the Dismal Depths Bestiary. For those keeping track, there are 11 new entries and some name changes; specifically Moorlocks = Phlemoks, Boglings = Bogloids, Mole Men = Mol-Min, Sleestaks = Saristaks, Blue Gunky = Bloo-Goo, Alfar = Aelfar. There were some other minor edits as well.
The new Bleak Beyond Bestiary is now available for download, along with a printable copy of the above scanned Random Monster Determination file, both situated atop the mediafire links section to the right under SHAM'S OD&D STUFF.
In the near future there will be more information concerning the Bleak Beyond.
