Pathfinder Campaign Setting: Rival Guide

The Rival Guide presents 10 fully detailed rival adventuring groups, complete with specialized spells, equipment, magic items, and unusual minions. These groups cover a wide range of themes, from haunted pirates to drow death cultists, monstrous slavers to nigh-unstoppable arch-villains, and much, much more!
Inside this 64-page book, you’ll find:
Full stat blocks for 40 different NPCs, ranging from relatively minor foes at CR 2 to world-shaking menaces at CR 19. Use these as rival adventuring parties, or split them up when you need specific NPCs or even last-minute player characters.
Background information on each group discussing its history and goals, as well as on how to incorporate its members into your game as rivals for your PCs to clash against.
Several new alchemical items, feats, magic items, poisons, racial traits, and spells, along with a new template for characters haunted by ancient, sinister spirits and a simple template for alchemically invisible creatures.
The Rival Guide is intended for use with the Pathfinder Roleplaying Game and the Pathfinder campaign setting, but can easily be incorporated into any fantasy game setting.
