This book is a lie. It does not contain six new classes. It contains over 40. The alternate class features alone change base classes so drastically you will not recognize a NPC with them as their iconic class without the DM tipping you off.

Between the Core rules book and the Advanced Players Guide you will be able to run dozens, if not hundreds, of adventures with no two characters alike.

Simply put this is the greatest supplement ever made for a player. Please enjoy responsibly.

Like everything Paizo has been doing lately this is a high quality product. The art is awesome, the layout is superb, and the content is top notch.

A staple of D&D systems is supplements with options for players to customize their characters. Every edition of the game has had a slew of such books. The quality has generally been highly variable. Most books have one or two neat new ideas in them, and a bunch of weird crappy ideas that no one ever uses. I have shelves full of past "Complete Warriors" and "Players Handbook 14's" which have seen very little use in campaigns I've run. This is the first such supplement I've ever purchased in which practically every page has a juicy new idea that I can immediately visualize being used in a game by one of my players in the immediate future.

My favorite thing in the book is the Prestige Class "Master Chymist". Designed to be a route for Alchemist characters to develop it is a wonderful riff on Dr. Jekyll and Mr. Hyde. The Master Chymist functions as an alchemist preparing extracts, tossing bombs, and whipping up magical potions to boost his allies most of the time. But this alchemist has imbibed a few too many of his own mutagenic concoctions. Several times a day he mutates into his alter ego, a bestial humanoid with a different name, and personality and goals - and supernatural abilities. When you build your Master Chymist you must design the two separate personalities (required to have differing alignments) and choose the particular mutations of your alter ego, which may be animal traits or magical resistances, strength, speed, sharp teeth or claws and such.

I already plan to create the pompous and calculating Lawful Evil Dr. Finias - investigator of the bizarre and macabre, and unscrupulous purveyor of hazardous chemicals; and his uncouthe mutagenic alter-ego "Moog" - Chaotic Good party animal and super-cuddly defender of people who feed him sweets.

I'm quite satisfied with all of the content in the Advanced Player's Guide; all of the class variants and new classes seem well-balanced and provide even greater opportunity for storytelling and role-playing.

The only issues that really caught my eye were the pervasive grammatical errors and some occasional mislabelings (see the Arcane Duelist option for the Bard, which has a few uses of the name Spellsword, and a few tables that use "a" for "an" and vice versa.

Great variety, good content for the price. It feels like the book was rushed through production at the expense of editing, however, and will require a fair amount of errata. Almost fully functional, but a few of the things that need errata are rather essential things, such as one of the Inquisitor's abilities that simply has no function without the errata.

This is the best supplement rules I have ever seen for any game system. Period. The sheer quantity of character build options is mind-boggling. It will take me months to read and absorb all the possibilities. Get this book!

This book is full of new and interesting options for play. From new characters, new character builds, new racial abilities, new items, new prestige classes and more. This book is the perfect addition to the core book and should allow you to make the perfect character just for you.

With this book, any player or GM will be able to customize its character to turn it into what he really wants it to become. The new racial skills are great, the six new base classes are awesome and the huge amount of feats and spells just make it all better.

Since I received my shipment of this book, I have absolutely loved looking through all of the pages at all of the new options that open up to me. For the most part, all of it seems really balanced to the material in the Core Rulebook... and that was the design goal in which Paizo did an excellent job for the most part. It provides more options, giving you better options to make your fantasy character as you envision him. And that's what a roleplaying again is all about. In particular, I love the six new base classes and I think they will be a lot of fun to play. The new class variants all seem very cool, as well. In particular, I like the Arcane Duelist bard and the Antipaladin (As a DM, I already am planning to place one is as a recurring enemy in a campaign). The new spells and feats for the most part are well-designed. They aren't broken, have a lot of flavor, and are useful. There are a few troublesome or imbalanced or unclear rules in this book (take a look at the forums at the moment for specifics, the forums are full of rage over certain issues in the book) so I may want to wait for the second reprint if you haven't gotten it already. I kind of wish Paizo would've spent a bit more time with the proofreading since a lot of these mistakes and game weaknesses could've been caught before the book was released. But still, a great book. Well done, Paizo. As a person who usually doesn't like additional rule supplements past the Core Rules (I heavily disliked the 3.5 power creep and ridiculous amount of source books), you have really started to change my mind with the Advanced Players Guide. I hope to see similar things in the future from you.

I've been really excited about this book since they originally announced it. So many other options available, and all of them with some really good flavor. Me and a few friends are already talking about who going to play an inqusitor for the next game, and out of three whos going to get the alchemist:P

From the alternate race features, to the well done prestigue classes, all in all I'm going to take alot from this book to use with my characters.

Overload. Where...to...start. Rarely does a book come along that is useful and interesting cover to cover. If you're looking for something with a crunchy filling to expand your game, consider buying this bad boy. There is so much good stuff packed in between the covers, to list out especially interesting and creative parts would be difficult...I don't have favorite parts, I have a new favorite book!
