Your Journey from Adventurer to King Begins Now!

Enter a world where empires totter on the brink of war, and terrible monsters tear at the fragile borderlands of men; where decaying cities teem with chaos and corruption, nubile maidens are sacrificed to chthonic cults and nobles live in decadent pleasure on the toil of slaves; where heroes, wizards, and rogues risk everything in pursuit of glory, fortune, and power. This is a world where adventurers can become conquerors – and conquerors can become kings.

Will you survive the perils of war and dark magic to claim a throne? Or will you meet your fate in a forgotten ruin beyond the ken of men?

The Adventurer Conqueror King System™ (ACKS) is a new fantasy role-playing game that provides the framework for epic fantasy campaigns with a sweeping scope. With the Adventurer Conqueror King System™ you can:

  • Play 12 different classes, including the fighter, mage, thief, cleric, assassin, bard, bladedancer, explorer, dwarven craftpriest, dwarven vaultguard, elven nightblade, and elven spellsword.
  • Easily customize your character using a unique, optional proficiency system. Make your fighter a berserker or your mage a necromancer!
  • Buy, sell, and trade common merchandise, precious silks and spices, and even monster parts and magic items in a balanced and integrated game economy.
  • Construct strongholds, establish kingdoms, and carve out a realm for your character.
  • Run a thieves' guild and send your minions to carouse, smuggle, steal, and commit other hijinks.
  • Establish a wizard's sanctum and explore the forbidden arts. Crossbreed horrific monsters in an underground laboratory, enact powerful magical rituals, build golems, craft magic items, or even transform yourself and your followers into undead monsters.
  • Build and run a living world for adventure on a grand scale. With game mechanics built to support emergent play, ACKS is the ultimate RPG for sandbox campaigns.

Whether you want to crawl through dungeons, trade with merchant caravans, run a merchant emporium, conquer an empire, or even raise an undead legion, ACKS supports your playstyle with simple, fast-playing game mechanics.

If you like ACKS, be sure to check out Secrets of the Nethercity, the new kilo-dungeon for ACKS, crowdfunding now at Kickstarter.

Unable to review as my partner bought me the core book.
Now planning to purchase more in due course.
My wishlist includes a complete set of 14 books.
( Fully intend to get the whole lot eventually)

Absolutely brilliant set of rules.
Love the attention in detail in how domains work.
This is excellent, quite unique.
Wish I got into ACKS sooner, glad I found it though.
(Was recommended by O.G.Joel.)
This system has broad depth, an intriguing scope.
Offering some unique options.
It's all tied in with ideas I've been working already.
Looking forward to collecting more the books.
In particular ... Players Companion
Heroic Companion
Axioms Compendium
Barbarian Conquers Of Kanahun

Autarch scratch an itch that is eye opening and original.

I read an old post over on the Autarch site about a second edition with the errata. Is this it? The print preview says it is the first edition. Does this PDF incorporate the errata?
Customer avatar
Alexander M October 11, 2021 8:14 pm UTC
Hi Rob! The PDF on DTRPG incorporates all of the errata. The physical second printing (it's not a second edition, just a second printing) is available for sale in a matte hardcover on my website,

Hardcover Standard perhaps since Premium prices jumped the shark?
Customer avatar
Alexander M July 02, 2021 5:02 pm UTC
Maybe I should do that, thanks for the suggestion. For now, I've left it as-is. I don't mind the lower profit margin for my core book since it's the gateway to future ACKS purchases.

Is there no longer a POD option for this title?
Customer avatar
Alexander M March 30, 2021 11:43 pm UTC
Armando, the POD option has been reactivated. Please note that while it says "color" the interior art is black-and-white. The color option was used just for the superior paper and ink quality. Thank you!

Customer avatar

Hello Rafael - there is not an official GM screen but we have a fan-made GM screen available at our website. It's at under "Downloads". Cheers!

Outside of the core rules what do you recommend getting to start with?
Customer avatar
Alexander M February 06, 2021 12:18 am UTC
If you're running in a standard D&D-style setting and aren't initially interested in mass combat, warfare, strongholds:
-- ACKS Core + Player's Companion + Lairs & Encounters

If you are very interested in mass combat, warfare, strongholds, add:
-- Domains at War: Campaigns
-- AXIOMS Compendium
Add in Domains at War: Battles if you like tabletop miniature wargames like Warhammer Fantasy or Warmachine.

If you want to play in the Auran Empire campaign setting, add (in this order, as you play through the setting):
- Auran Empire Primer
- Sinister Stone of Sakkara
- Capital of the Borderlands
- Secrets of the Nethercity
- Ruined City of Cyfandir
- Eyrie of the Dread Eye
- Sepulcher of the Sorceress-Queen

If you are interested in trying out alternative settings such as high fantasy, swords & sorcerery, or renaissance muskets-and-magic, get one of these:
- Heroic Fantasy Handbook (LOTR/Earthsea/Hyboria)...See more

I just recently found about this game.
Since I missed the Kickstarter, I missed on a great quality printing (at least the one I saw on YouTube was of great quality).
How good is this POD version compared to that?
Customer avatar
Alexander M August 18, 2020 9:35 pm UTC
The POD quality is good. It's not as good as the beautiful KS book, but it is more than serviceable at the gaming table.
I personally play with the POD version and so does most of my personal group.

Esteban M September 01, 2020 2:14 am UTC
We shall see!
Everything I've read about the game is just pure awesomeness... So I decided to buy every single one of the books available for printing

If anyone wanders the discussions like me, before making a purchase; let me tell you:
Since I wrote the first comment, I now own 2 copies of the core rules, 3 copies of the heroic fantasy handbook, 3 copies of the players handbook, 3 of the player's companion, plus one copy of every other book available for print, + some adventures.
The game is THAT good. The layout is great, the quality is great and the rules awesome.
Yes, the game is almost 10 years old but no, it doesn't need a new edition, even if you decide to use alternate rules from the heroic fantasy handbook or axioms compendium; they are grouped and clearly explained, they don't feel like patches. The game has been masterfully designed and I give all my praises to everyone involved in it's design.
It's a shame currently the core rules are not available for POD, but you can find cheap copies (and of better quality) on amazon.

Please do yourself a favor and buy this ASAP if you're interested in OSR or high level play....See more

Ok, so this is basically a "hack", but on which edition of D&D is based?

Any chance we could get a version of this PDF with black line-art on 'white' pages for those chapter headings? Each one of those pages consumes a few hundred 'normal text' pages worth of toner. It's just too expensive to print out a copy of this book for the table. I prefer to keep my hard/soft cover copies untouched by sticky Dorito'd fingers on my shelf.

I have just recieved hardback copy having previously bought PDF. Happy with both.
Got the PDF to check it out. transitioned Dwimmermount game over from Dungeons and Delvers low level game I'd been running using Labyrinthe Lord version.
Little bit simpler than full D&D rules cyclopeadia (not a bad thing) but with more detail for character domains and campaign development whilst having similar feel.
Good job!

The PDF appears to be coming out blank. Is this a known issue or is the problem on my end?
Customer avatar
Alexander M January 15, 2017 5:48 pm UTC
Ciaran, that's not a known issue. If you're continuing to have problems let me know and I can send you a coupon for a new download.

I recently purchased the pdf/combo of the ACKS main rule book through I am extremely disappointed with the quality of the printing. The paper is thin, flimsy and see through. Very cheap feeling. The print and tables are look like they were printed on home office inkjet a printer running out of ink, they are muted and hard to read. The hard cover binding is fine but the paper and printing is just awful.

I regret paying a premium price of $30 for this product.

Alexander M June 09, 2016 1:37 am UTC
Thaddeus, I'm sorry to hear your book came out so badly. We here at Autarch don't control the quality of the printing process unfortunately - it's standardized at each tier - but if you email us at I will address your problem directly. Thanks for checking out ACKS.

In the current version of the PDF there are issues in the Monsters chapter. Specifically, the images (e.g. Elf, Gnome, Ghoul) cover up text. Is it possible to correct this? Thank you in advance.
Customer avatar
Alexander M March 25, 2015 2:36 pm UTC
George, it's been fixed - please let us know if the latest version has any issues.

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.
