VANQUISH TERRIBLE EVIL
Eric Cagle, Jesse Decker, James Jacobs, Erik Mona, Matthew Sernett, Chris Thomasson, James Wyatt
The noblest heroes must contend with the foulest monsters. Whether torn from the darkest planes of existence or spawned as blights upon the natural world, the creatures bound within these covers will challenge stalwart adventurers of every experience level.
This accessory for the D&D game captures over 150 monsters, including some of the most diabolical beings imaginable. While focused on extraplanar and otherworldly creatures, you'll also stumble across new creatures of every type, with Challenge Ratings that range from 1/8 to 25. Along with three new fiendish prestige classes, six new templates, and rules for swarms, grafts and symbionts, the Fiend Folio offers a multitude of challenges for every hero. (from the back cover)
The Fiend Folio is a 224 page hardcover bound book with color illustrations throughout. Use of this book requires the three core rulebooks of the D&D game (3e or higher).
