Here's the most valuable compendium of advanced and extra-planar monsters in existence for AD&D. Gary Gygax's last major contribution to the menagerie includes many old favorites, most of which were expurgated or "toned down" in the later, politically correct version of the game. You get dozens upon dozens of demons, devils, undead, demodands, daemons, dragons, giants, and more; if it's evil, and fun to kill, it's here! Lots of classic illustrations, too, far superior to the later Monstrous Manual (bleah!). Find out why it's an eternal DM favorite!
