You will need the D100 Dungeon rule book to use this book.


Below are some details on the PDF and Print on Demand options available to you, which might help you to choose which product is right for you.

The Watermarked PDF is what we refer to as the Digital Edition. The watermark is very small and appears at the very bottom of every page on the left hand side. It will show your account name and an order number; it will not block or cover any of the text inside the book. The pages have a white background.

The Hardcover, Premium Color Book is what we refer to as the Collector’s Edition. It has a collector’s badge on the front cover and a gold spine effect. The pages inside are printed in full colour with a background on premium paper. The book has a glossy hardback cover. Please note: There is not a Collector’s Edition of the Watermarked PDF, and so if you choose the “Watermarked PDF + Hardcover, Premium Color Book” option, the PDF you download does not have the full colour background.

The Hardcover, Standard Color Book is what we refer to as the Hardback Edition. It has a standard badge on the front cover and a blue spine. The pages inside are printed in colour on a white background and on white paper. The book has a glossy hardback cover.

The Softcover, Standard Color Book is what we refer to as the Softback Edition. It has a standard badge on the front cover and a blue spine. The pages inside are printed in colour on a white background and on white paper. The book has a glossy softback cover.

PLEASE BE ADVISED: At times the print on demand books will need to be updated and may be temporarily withdrawn from the product range. This process can take a few months to complete, and will become available as soon as the update is complete. We are sorry for any inconvenience this may cause.

Got the rule book.
Interesting economics.
For the price of less than three small rooms, you can buy a castle.

Are the 'PROPERTY' rules for buildings, or land, and more importantly, why would an adventurer want to buy either?

Seeing is believing.
Superb product.
Swift shipment.

Hardcover covers are genuinely pleasurable. Sturdy, glossy. A little taller than average.
Binding appears ideal. At only about 70-80 pages, not a lot of weight if stored upright. I don't expect trouble.
Stiff heavyweight paper, beyond industry norm if you ask me. Nice matt surface, no glare trouble for reading.
Efficient page usage. There isn't a lot of pointless dead space. The artwork is not extensive but is stunning.

These might be some of the best gamebooks in existence at the physical level. I will be adding this exact review to my other 3 purchases because I feel the same about all 4.

A great book for experienced players. The beast mastery rules are clever. I'm thinking about modifying these rules for recruiting retainers in town.

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.
