The Adventurer’s Companion (Book 2), is an essential guide for any adventurer wishing to spice up their games. It offers new rules and additions that can be implemented into your games, and contains a new way to play quests, with the introduction of a campaign quest line and side quests. It is an essential companion to continue exploring your adventures.

The Adventurer’s Companion adds the following:

  • An adventurer fast track system, that will create adventurers that are quest ready and have already completed their first 5 training quests.

  • Rules to play with additional players, making the solo game, a multiplay game.

  • A Special encounter rule that is quick and simple and will eliminate encountering the same monster a lot of the time, due to the Encounter Modifier.

  • A new Encounter Table, with new monsters and abilities, that you can choose to use instead of the one in the main rulebook.

  • New Hero Paths and new Races.

  • A crafting system called Witchery that will allow your adventurer to combine parts looted from monsters and make them into special potions and anointments.

  • A Brief description of skills to help determining the best areas to place experience pips towards. Rules to create your own quests.

  • A new rule called Death Kill, that will convert those really high damage scores, that wipes out a monster into a bonus that is applied to the loot table and a narrative of how your attack affected the monster.

  • A 20 quest campaign with an interlocking story and narrative.

  • 25 additional quests to play.

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 parchment 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 parchment 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 grey 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 grey 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.

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.

Hi Martin,
Amazing game, you are a gaming wizard! Thanks for creating this and allowing me to feel my 1980s D&D in a solo experience. I’m using v 2.2. A comment mentioned that this adventures companion can convert my character to v 3. Is that accurate? Can I use this book with my v 2.2 rule book, more or less?

Martin K March 14, 2022 8:31 am UTC
Hi David, thank you for the kind words and it's great to know you're enjoying D100 Dungeon. The differences between versions can be found here: at the very bottom of the page. The character conversion would not be very useful unless you owned and upgraded to the V3 rules. However, some of the content could be manipulated to work with V2. You could use the hero paths and new races to convert your adventurer for instance. Other things within the adventurer's companion could say 90% of the time work using V2 rules. However, if say you wanted to use Witchery, one of the potions and one mishaps refer to shaded experience stars, which is one of the upgraded components to the rules in V3. In short, you will get the most out of the game and its expansions if you fully convert to V3. I hope this helps.

Thanks for such a quick and thorough response. I definitely want to upgrade to v3! In the meantime...,
How does the world builder expansion relate to v2?
Customer avatar
Martin K March 15, 2022 8:21 am UTC
Hi David.The world builder and v2, may be more achievable than say trying to implement some of the other expansions. However, to fully enjoy any of the products here on drivethruRPG, V3 is going to be giving you the best out of your gaming. Trying to implement the expansions into v2 undoubtedly there will be gaps.

Has the softcover option been removed temporarily?

I too was hoping to purchase additional books but would prefer softcover.

Same here, I have books 1 and 6 as softcover and wouldn't want to mix it. It'd be great to have the rest of thr books available in softcover as well! Completely hooked to the game!

Hi Paul, Petri and Peter, Firstly thank you for your support with D100 Dungeon. I am very grateful for your custom and that you are enjoying the game. Regarding the soft back books, periodically the print on demand files need to be updated. The soft covers are going through the update procedure at the moment and will return for sale afterwards. It often takes over a month or more to complete and there is no guaranteed time frame. Sorry for any inconvenience.

Hi Martin! Thanks for the reply, will put a reminder to check back here to grab the rest of the books when the aformentioned update is done!

Why there's only a hardcover option available? I already have 2 softcover books and don't want to mix it.

Thank you for enabling personal printing.

Hi Lee, your welcome. I am glad by switching off drivethrurpg non-printing security it will allow players who can't get the printed books so easily, can still enjoy the game and its content by self printing.

I have a question. I am really thinking about buying all for this game but.... I play with my wife, thus solo is not ok for me. With this ruleset, are all other campaigns playable as 2 player game? Because I want to have a story, so I guess with this I can play a general dungeon but are all other story driven books playable in co op?
Customer avatar
Martin K July 05, 2021 7:28 am UTC
Hi Radovan, yes the campaigns in the campaign books and the adventurer books (the adventurers companion, the dragons return and the dragon armour) are all compatible with the party rules.

Given the pandemic would you please consider removing restrictions on the PDF? I would love to be able to actually play this game. Can't purchase it if I can't print the thing.

Is there a reason that this product, as well as the original d100ngeon, aren't printable?

Edit: Nevermind. I just read several statements from the author concerning his stance on printing. Frankly, it makes no sense to me, but it's certainly his choice. I'll stick with some other products that allow me the flexibility to configure my gamespace the way I desire.

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.
