CASTLE OLDSKULL - Oldskull Dungeon Generator

Watermarked PDF

Hello all, this supplement features an immense Gygaxian OSR random dungeon generator system, crammed into 83 pages. It’s focused on empowering you to create the sprawling level 1 of any mega-dungeon, or any smaller dungeon set to challenge adventurers of experience levels 1 to 3.  The challenge levels of the monsters, traps, tricks, and treasures all reflect that difficulty level. You can use this book to design any number of dungeons, and if your group is patient you can even use it during play. You will also find some experimental solitaire rules here, if you like to practice the dungeon crawling yourself! This book’s systems interlock with the Classic Dungeon Design Guide series (CDDG1-3) as well as the Book of Dungeon Traps (BDT1) if you want to add more detail to any aspect of the design.

The system is comprised of many branching D100 and D1000 tables. Sub-systems are provided to generate: [1] starting areas, [2] random doorways, [3] corridors, [4] dead ends, [5] level connectors (stairs etc.), [6] unusual level connectors (teleporters, slides, etc.), [7] monster lairs, [8] monster-guarded treasures, [9] room size and dimensions, [10] room exits, [11] unusual doors, [12] room contents (lair, trap, trick, etc.), [13] side passages, [14] traps, [15] tricks (a full 17-page system with millions of potential results), and [16] unguarded treasure hoards. At the end you’ll find an Appendix with troubleshooting and solitaire advice, and a quick reference hyperlink section which will allow you to flip through the tables quickly. (Full PDF bookmarks are also provided.) 31,000 words. Please refer to the preview for more detail. Enjoy! ~K

Just bought this and found a glitch, the title of this one is, "GEN1 Oldskull D100 NPC Generator" instead of, "CASTLE OLDSKULL - Oldskull Dungeon Generator"

Are you planning on additional Dungeon generators for the deeper levels? ( I ask because I'm a solitaire gamer for now...)

Hi there, I'll most likely add additional dungeon level generators later this year if there's enough interest in my writing them :) I can give you a preview of what the next one would have - it would be for character levels 2-4, featuring lethality level 2 monsters, mega-dungeon level 2 traps (from BDT1 The Book of Dungeon Traps), slightly more lethal/beneficial tricks, and treasures that are about twice as valuable, with more magic items. I don't think the primary generators (corridors, doors, rooms, level connectors, etc.) would change much. If you play D&D, I would recommend using Fiend Folio, pg. 102, Monster Level II encounter table, along with BDT1, doubling trick power, and doubling treasure found, and you would be able to roughly simulate what the next deeper level 2 would be like. ;)

Thanks for the insight! I hope there is enough interest for you to do an "official" one, but your advice is much appreciated!

Original electronic
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.
