A terrific resource for players and GMs alike


More than any other Paizo AP (in fact, more than any other campaign I've run in 33 years of gaming), Kingmaker requires legwork for the GM and lots of it. Not only do you need to run the players through the adventure as presented, but if you want to get the most out of it you need to create scores, if not hundreds, of vibrant NPCs, give each PC their own plotlines to develop, and think several game-years (at least) into the future. The result can be an unparalleled immersive experience for everyone involved, but make no mistake, it takes a LOT of work to make it so. Therefore, anything that can make your life easier as a GM is something to buy, treasure, and recommend to others.

The first thing to take into consideration is the title. I think it's a bit unfortunate, since this is far from just a PLAYER'S reference; GMs will find much to love here.

I purchased the PDF version, so my comments are limited to that. Physically it's a nice book, with a lovely cover, good B&W illustrations throughout, clean text and presentation, and not a lot of page background to mess with readability or devour printer ink.

The first section deals with exploration and is essentially a restatement of the rules in Stolen Lands, with a couple of nice additions like a size-comparison chart showing how big a kingdom is with RL comparisons. It's fine, but nothing thrilling.

Next is city and kingdom improvements, which is where the book starts to shine. All Paizo's buildings are listed, but additions are made for cities (like Office of the City Guard and Witch's Hut), rural areas (like Apiary, Winery, and Royal Preserve), and even castles (ranging from a fancy art collection through a moat to an anti-scrying room). This is where the book starts to become indispensable, as much time, effort, and balancing will be saved by having these structures ready to hand, in addition to giving players more of the options they crave. A much-improved random events table is also included.

Next up is mass combat, and the additions here are very useful indeed, ranging from new army types (everything from various size militias through orc raids to everyone's favorite shambling undead cannibals) through new attributes (like bleed, crusader, and mercenary) and rules to generate the sort of humanoid hordes we all know and love. If you plan to feature a lot of mass combat, you NEED this.

A short section on new Feats follows, which gives both traditional (e.g. Armored Swimmer or Tumble Strike) as well as Kingdom (e.g. Aid Another Leader or Inspiring Ruler)and Mass Combat (e.g. Mass Combat Focus and Inspiring General) options. Again, for someone really wanting to get into the building rules that make this AP special, this is excellent stuff that you will make use of.

The next section is for new spells, and it's here that the only real problem I have with the book comes, in the form of the various "Summon Army" and "Summon Nature's Army" spells. They're only usable by mass combat units, but I still think the present serious balance issues. Still, YMMV, and I'm sure some GMs will find them perfect for their games.

A very interesting section, somewhat misnamed as "Secret societies and organizations," comes next. it has two 5-level prestige classes and a pair of new archetypes, all of which are good, useful, and interesting, but nothing in it can replace, say, the sort of thing found in the Faction Guide if players wish to found their own organizations.

Two pages of magic items are the last major section, and these are generally useful, especially the magical statues that grant kingdom bonuses when placed in Parks. More could have been done with kingdom stat-modifying items, but that's a quibble.

Rounding out the book are several pages of revised forms for kingdom tracking, which is fine, although I think the majority of GMs find that the kingdom must be tracked through computer spreadsheets. These forms are fine and you'll like them if they're the sorts of things you like.

Overall, this is a truly exemplary resource for players and GMs using the Kingdom Building subsystems in their games. It's not perfect, but it is clearly a 5-star product and an absolute steal at its price.



When I decided to start up my Kingmaker campaign, I knew I had to have this book from the reviews I've read and it hasn't let me down. My group is still slogging away through book 2 but they have already gone through 4 and half years of kingdom builing. The players have enjoyed the extra buildings and, as the GM, I've really enjoyed the expanded random encounter section. Additionally, being available in print makes it more convenient to flip through at the table. What also impressed me was the community support of this product by creating an excel spreadsheet that incorporated the extra material in this book. This has made the kingdom building aspect a breeze to keep track of.



The book starts from the basic exploration, kingdom/city building and mass combat rules as presented in the Kingmaker AP Chapters 1, 2 and 5.

As written it's quite useable and has a few interesting changes as noted in previous reviews, such as the change in the square miles of the area a hex encompasses. Trivial point: the area of Washington D.C. is a bit under 70 square miles, so you can fit more than 5 of them in a single hex.

The kingdom building chapter adds in a substantial expansion on "farmlands" from the original rules, changing this to "open spaces development". This is the best part of the entire book, one I am adding in toto for my own campaign. This gives a reason to remember where your various landmarks are at on your kingdom map, as you can do something with most of them.

The revisions in this book for building cities and the changes in the actions by size of kingdom in my opinion are unnecessary.

There are a few new buildings, some of which are "odd". The majority of the new buildings are underpriced variants of the tradesman building in the regular rules that don't require houses be adjacent. The Keep is a variant of the Barracks that costs too much. The additions to Castles are nice, although the moat is badly explained and the 'wards' one is either overkill or far too easily bypassed by other means. Best to remove it from availability.

Mills are incorrectly assumed to only be used as a lumber mill and require substantial water access. More mills are likely built and used to grind grain than mill lumber and can be build on a much smaller river or stream than can a pier. As these rules stand, you have to have a carpenter for quite a few important items - which means in order to build various stuffs you will want every city built on a water border to build the mill that the carpenter requires. This doesn't really work well... Some of these discrepencies derive from the original material.

The militarily-required buildings are generally unecessary as well, although they are tied into the mass combat section of this book.

The mass combat system is a nice attempt at changing the admittedly basic one presented in Chapter 5 of the Kingmaker AP. The consumption costs are generally far too high, especially on a weekly basis. The training system works well enough, although using it as-is might not be so satisfactory for some.

There is a new tactic for victorious armies to learn and 4 new resources to upgrade armies with. These are also good additions and ones I plan to integrate in toto. I suggest that the poison resource inflict damage to the army using it as well unless that army is comprised of creatures with the poison use class feature or that are immune to poison.

There are several special abilities added - only Mercenaries is worthwhile. 'Bleed' is best left as originally presented in Kingmaker as part of the 'poison' special ability, while 'Crusader' is too subjective. Everyone will argue that all of their armies are crusaders to shave those consumption costs down.

Vassal armies I think are a good concept that in the book that is not well executed.

The army construction rules present an interesting concept: limiting maximum army size by 'method of conscription' - based on whether the army in question is conventionally recruited and trained (marshal), divinely acquired (planar allies?) or 'arcane' (which covers all the rest of them).

There are several new feats presented, most pertaining to govorning your kingdom or leading your armies. They are good enough to use, although Sickening Strike I would remove. Dirty Trick is already able to do this and doesn't quite require the "feat taxes" to acquire the feat. The rest of them seem fine, although Mountain Strike I would caution against unless you are willing to have some of your bad guys get it too.

The mass combat spell section has some problems as well. I cannot recommend integrating it as-is. The summon army spells are - while written for entire armies of wizards/sorcerers/clerics/druids - an especially bad idea. The effects of summoned monsters on this scale are sufficiently covered by that army's "spellcasting" special ability.

The only two non-army spells of note (besides the two that deal with scent) are (a) magic wall - which omits the very important detail of how much it costs and what the minimum caster level should be to make it permanent; and (b) wall of tentacles.

My beef with this supplement's army building rules are identical to the original ones - purely RAW they are way too easy to abuse. Armies of hound archons are the same cost as an army of 5th level fighters - both are a base CR of 4 as a Medium army in this example.

The same complaint goes for armies of golems, pixies, rust monsters, great wyrm dragons ridden by 20th level wizards and so on. There should (in most campaigns) be a hard cap on what one can recruit and train in such numbers.

This supplement attempts to reign that in by the consumption cost / week of resources = same as the cost to purchase. This really doesn't work well, as it makes armies too expensive without addressing the core problems.

The magic items are largely fine - but I caution against the trio of statues. As they're written, a group could plant one of each in each city for pretty cheap and rachet the kingdom's bonuses up even further. In a nutshell, one park per city(6 BP, most often either 3 or 1 BP) 'unlocks' access to these statues. Presumably the PCs are able to craft them, so they cost half. The +1 statues are a bargain at 2.5 BP each - the reason? Each *city* can have one of each statue in their park. I recommend house-ruling the highest such bonus provided by these statues be applied to the entire kingdom as an enhancement bonus. Otherwise, one set of +3 statues - at a 'retail' cost of 135 BP - provides the same benefit as placing a set of +1 statues in each of 3 different cities at a 'retail' cost of 22.5 BP. For the same price as one set of +3 statues, you can acquire a +18 to Economy, Loyalty and Stability for the entire kingdom, provided you have 18 cities, which is not hard to do.

Must Have For Kingmaker GMs


I picked this up for a Kingmaker campaign I'm running. It collects all of the rules from Kingmaker for exploration, kingdom building and mass combat in one place. While I have not taken the time to do side by side comparisons, all of these rules systems seem to be expanded and the expanded material blends seamlessly with the original material.

The absolute best part of this book is it can be easily shared with players as a reference work while performing kingdom maintenance without making the adventure and gm-eyes only sections of the Kingmaker Adventure Path books easily accessible to players. For that reason alone I consider this book money well spent and an absolute essential for any GM running a Kingmaker campaign.

Great content, but prefer better binding


Other reviewers have already summed up how immensely useful the content of this book is. There's no need for me to rehash that. The few typos and lack-luster art would not be enough for me to deduct more than half a star.

The reason then that I am rating this at 4-stars rather than 5 is for the printed copy of the book...

Unless the printing method has changed, the copy I received has a folded and stapled binding with non-glossy pages. Had I known that before-hand, I would have simply purchased the PDF-only and printed my own copy. I much prefer the more durable type of bindings used for the Adventure Path volumes, and appreciate the fact that I can open them even to the foreword or bestiary and still have them lay flat on my desk without issue. The same cannot be said for a stapled binding such as this.

As feedback then, I would just like to say that I find far more value in paying a few extra dollars for a good-quality binding than saving what amounts to a couple cups of coffee.

To Recap:
PDF: 4.5 stars (essential content, mediocre artwork)
Book: 4 stars (as PDF but binding is stapled)
Would I buy it again? Yes. I'd buy the PDF and then bind my own copy.


6/04/2011: Note that as of the 2nd printing, this book is now perfect-bound! Great to see customer feedback implemented so quickly! Adjusting rating to 4.5 stars for the book too which it up to 5.

Note: One small thing to keep in mind when using this book is that the hexes are of somewhat different size than those in Kingmaker. They are 12-miles to the side, whereas the ones in Kingmaker were intended to be 12-miles from center-to-center. The difference is 375-sq miles vs. 125-sq miles. Very little (if any) effect on gameplay, but I figured it was worth mentioning in a review. More info on the difference here.

For the devout healer maximize healing ability, does it require the plus three level like the feat does? If so, I don't see when I would ever use it. My 10th level cleric/healer can cast a 4th level cure critical for 4d8 +15 which is much better than the maximized cure light...especially with the paragon healer ability making the ccw being a minimum of 31 ho healed.

Thanks for the help!

Just wanted to pop in here and say that this was a MUST HAVE at our Kingmaker game. We got the PDF (in Sweden) and printed out what we needed, and the GM printed it all out and taped up pages on his GM Screen. Very nice!

Will this get an update now that Ultimate Campaign is out?

That is definitely a better name than "Book of the River Planets". ;)

amazing kingdom builder book, you really should make a new updated version with even more goodies!

It definitely is a good book. I rarely buy physical third-party books and this was an exception years ago. I like Zuoron's thought on an updated version!

Well, considering that we are continuing with Pathfinder support, an update to this could be in the cards. I'll talk it over with the team.

Well, I would most certainly buy it. I always much prefer this one to the official stuff and to this day I still use this book.

What I want the most is even more Kingdom Events and also something to make cities have a bit more personality at the construction step.

Other things were more things to build in the countryside, different types of roads and balanced setup for different leadership structures. Like a council leadership rather than a single ruler, or elected leadership.

Rules for letting minor nobles having land without it totally ruining the economy and possibly ideas or rules for how they can levy their influence on the country/kingdom as a whole.

Clearer "rules"/guides for interacting with other kingdoms (like trade agreements would have an effect or how a vassal/colony would influence the country as well) as well as diplomatic events.

Rules for standing army, as the rules seem to reflect an army engage in active warfare.

Anyway, these are just my thoughts on the subject.

Something like 5 years ago or so, I started work on exactly this. Short of the long, I never liked the fact that the rules essentially took place in a vacuum. With the exception of mass combat there are no rules for interacting with another nation whatsoever. No rules for nation A to use nation B to get at your nation. No rules for a nation to place tariffs on another. I always found that lacking.

I started work on addressing that but I got sidetracked. Perhaps it is time I dust that work off and get back to it.

Sounds like an excellent idea, this whole in a vacuum was a problem I had as well. I understand that it is supposed to be up to the GM and allow the interaction to be fluid and flexible, but when you don't have any real guidelines at all it becomes a chore to keep it reasonable.

As a GM I want to have strings to present and manipulate, as a player I want to have something to plan around.

We still sell a few copies of the Book of the River Nations here and there. I'm just curious if you've bought it in the last 3-5 years, do you use this book for Kingmaker or are you making rules for your own campaign?

Tell us how you are using these rules.

Jon Brazer Enterprises

If you haven't download the Book of the River Nations, you should see why your fellow gamers love this book so much. Download today.

I haven't had a chance to use the rules recently, but I used the rules originally for Kingmaker (basically I replaced kingmaker rules completely as they were poorly explained).

I also used them to do several small narratives where I wanted to see how a nation in a pathfinder nation could arise, once for a kobold nation which I tracked for the first 50 years and another time for an island nation which I tracked for 250 years (though this one was mostly for practice).

I planned to use to sue the rules for a small campaign where the heroes were an incompetent noble's advisors, he would basically leave all to them and just train resources to live in luxuries. The game itself was to be centred around a small outpost the marked the border between the kingdom and three different hostile wilderness. The heroes would need to grow the outpost deal with local trouble, whims of the noble, external threats and pressure from the kingdom itself.

I used the rules to help me build up fantasy maps to populate them and make sure there is enough stuff to make it a bit more balanced. Check the economy by applying the rules have helped me get a better sense when world building. It has also helped with getting a feel of the scale.
