Your Complete Tome of Fantasy Creatures
Monsters from the aberrant to the yellow musk zombie appear in this book, and everything in between--that's over 700 monsters. But that's not all; the appendices bring just as much to the table from templates to hazards to a treatise on poison variations in nearly 50 types of venomous snakes. There are also new feats, planes of existence, strange beings beyond mortal ken, and plenty of charts dividing the compiled monsters by level, type, and terrain.
