CASTLE OLDSKULL - The Classic Dungeon Design Guide II


The sequel to the Classic Dungeon Design Guide is here ...

Have you read every dungeon design book out there, but you’re still hungry for great ideas to amaze your players?  Would you like to possess the tools to generate countless millions of randomized results for bizarre rooms and shrines, dungeon doors, magical laboratories, skeletons, Lovecraftian abominations, and torture chambers?  Then this is the book for you.

This massive tome is the direct sequel to Wonderland Imprints’ Gold Medal Best Seller, CDDG1:  THE CLASSIC DUNGEON DESIGN GUIDE.  Where Book 1 was a basic inspirational tome filled with thousands of ideas, Book II:  Dungeon Mastery Design Tables is an advanced nuts-and-bolts guide that provides you with hundreds of pages of tables which you can use to create an infinite number of dungeon rooms, monster lairs, thematic levels and endless details such as barracks, caves, chests, corpses, fountains, prisoner cells, quarters, shrines, and magical gateways.  You can even use this book’s treasure trove of systems to create millions of deities, slime monsters, prisoner NPCs, and unique NPC villains and prisoners, using nearly 1,000 different experience level titles and other tools that intersect with DDE1, DUNGEON DELVER ENHANCER.

Book One was only the beginning, the entry work to a series.  This is one of the largest and most extensive dungeon design books in existence, with features branching out from CDDG1 including:  data for on-the-spot creation of altars, barracks, caves, containers, corpses, doors, dungeon dressing, fountains, fungi, galleries, hideouts, laboratories, magical gateways, prisoners, quarters, stairways, torture chambers, unusual rooms, and those ever-baffling magical “unclassifiable chambers” which no one can fully comprehend.  It’s all here, the massive set of tables I have used for years to create new mega-dungeons for the Castle Oldskull OSR campaign.  I have refined and expanded them over many months of writing, and now I offer them to you.

So what are you waiting for?  This book is the perfect companion for THE CLASSIC DUNGEON DESIGN GUIDE, and has been specially designed to serve both as a learning grimoire and as a tabletop go-to book for design and for sandbox play.  After all, if you’re going to dare to delve into the netherworld, you should probably take not just a lantern and an elvish sword of great antiquity; you should also carry the ultimate guidebook to help you from getting lost along the way …

Another classic Fantasy Role-Playing Game Supplement from Wonderland Imprints, Only the Finest Works of Fantasy.  (67,700 words, 406 pages.)

Simply incredible. I'm inherently cheap, and I don't like buying pdf files.
But this is me saying, hardcover please.

Go for it Kent. Your books are good. I grabbed all 3 of the Dungeon Design Guides today.
Your books look very solo friendly in that I can imagine myself creating with your products, and using them to enjoy solo gaming through them.
Going to copy paste this two the other 2 tomes, as I feel the same about all 3.

Are you planning to reformat this PDF as you have the first book?

Hi there Christopher, good to hear from you. That's the plan, but I'm moving in reverse popularity order ... so the next title to be updated is going to be the Oldskull Adventure Generator, which is going to take some time. I hope to have this one updated in the months to come. :)

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
