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.
