From publisher blurb:
The 140-page book is the ultimate guide to designing the perfect scoundrel PC or villain NPC, and a must have for any player or Game Master. This book is loaded with new rules material including:
A step-by-step guide to villain design
7 new prestige classes
24 new villainous feats
revised rules for anti-feats
81 new evil spells
vicious new combat options
new monsters and undead templates, detailing the rituals for creating all kinds of intelligent undead
Additionally, this tome includes information on: breaking stereotypes; detailing the villain's motivations, obsessions, goals and schemes; and choosing the villain's alignment (and why good-aligned villains are not only possible, but plausible). Detailed emotional archetypes, suggestions for villains and experience, supernatural villains, familiars and many different types of villainous organizations (including assassins' guilds, black marketers, raiders and more) give the evil PC, or the Game Master, a wide variety of new ideas and role-playing insight.
Furthermore, this supplement provides an abundance of information with which to customize any campaign setting. You can make use of the many features of this book in your Kingdoms of Kalamar campaign or any other campaign world. New information on summoning outer planar creatures, becoming undead, hiring henchmen and lackeys, or building a lair ports easily into any campaign. An abundant source of material of the high quality you've come to expect from Kenzer and Company, this is one product you don't want to miss.
Remember, great heroes need even better villains.
