PDF. 223 pages. Full-color covers and interior art.
For this review, I am considering the PDF from DriveThruRPG and my hardcover I had a number of years ago.
Published in 2007 this was one of the last hardcovers published for the D&D 3.5 game prior to the announcement of the D&D 4e.
I picked this one up cheap at the local RPG auction and I think I sold it back at next year's auction. Not a ringing endorsement I know, but in mine (and this book's) defense I was reducing my 3.x collection to make room for more OSR books and the upcoming 4e. I am glad I picked up the PDF though.
There are just over 110 monsters in this book (ranging from CR 1/2 to 22), the least amount for any of the "Monster Manuals" for 3.x. There are 11 templates, and many companion and summonable creatures. There are even new feats and spells. So at least this late in the game there is (or was) new material that could be shared.
The monster entries are again limited to whole pages. To make up the space there are "Lore" entries on some monsters. Others even have a Sample Encounter, Typical Treasure and/or how the monster appears in various campaign worlds. I admit these do not feel like padding and instead feel like a value-added feature.
Alignments are also prefaced with "Always" or "Usually" in some cases, giving more variety to alignments.
Among my favorite creatures here are" the Arcadian Avenger, the various new demons, the unique Dragons of the Great Game, Frostwind Virago, the God-Blooded creatures, Kuo-toa (finally!), Mindflayers of Thoon, Skull Lord, Spawn of Juiblex, the unique vampires, and the Wild Hunt.
While I was expecting a lot of "also-rans" and some diminishing returns on monsters this one actually is pretty good. The details are greater for each monster entry, so this explains the low monster-to-page ratio here.
Still, you have to be playing D&D 3.5 to really get the most out of these monsters.
