The book covers every monster in MM that doesn't have an ECL (HD + level adjustments) greater than 20. It also breaks down some of the more complex monsters into a monster class so that you can start playing one at 1st level. Creatures like orc, goblin, hobgoblin, don't have any racial HD nor much of a level adjustment, so there's no need for a class breakdown. Bugbears, gnolls, etc. have HD but no special powers so a class breakdown is almost trivial, once you have the level adjustment. The ogre is probably the most mundane creature broken down into levels and so serves as a decent guideline.Chauzu said:Wait... so there's no orc, goblin, bugbear, hobgoblin, gnoll etc?
If not... then I'm gonna have to skip this book. I'm not going to buy the book just for the minotaur, deinonychus, or illithid. I wouldn't allow most of the oddball monsters like vrock, titan, or ankheg, or whatever weird stuff is in there.
The book also has feats, spells, prestige classes, a whole bunch of new templates, and some suggestions on running monster-themed campaigns.
