I snatched up a preview copy at PaizoCon. Adam "Monster Man" Daigle and Mike Welham have produced an amazing resource. From Tiny to Large, there are drakes to fit every campaign niche. And, if you cannot find one that fits, there are rules to build your own. The player class resources (companion rules, spells, feats) are excellent as well.
What is your favorite drake? Mine is the "alehouse drake"!
I just picked this up at #PaizoCon. It is an excellent source of interesting feats for players & GMs alike. But, my favorite part of the book is all of the commentary, both on the feats and in the sidebars. People looking to transition to professional game design should own this book.
I've run a lot of PFS mods so far and this one remains my favorite! The climax, if done well is both a threat AND a hoot! If you plan to run it, please check out the boards for some cool ideas of how to stage the climax.
The easy complaint here is ... "Haven't I seen most of these monsters somewhere else before?" The answer is ... "Yes, but not like this!"
As always, Paizo hits it out of the park with their art direction and production value. The book is a visual stunner. Each illustration is familiar, but uniquely Pathfinder/Paizo. Information design is excellent, which is one of my major quibbles with other creature collections.
But what about game play? Isn't this just a collection of mildly changed stat blocks? Nope.
Like the Pathfinder RPG itself, each monster is reworked to fit the improved OGL d20 ruleset. Broken monsters get fixed and monster creation & advancement are greatly improved.
