From feral beasts to supernatural sprits from the realm of fey, the Kingmaker Adventure Path forces heroes to test their might against hundreds of foes, be they bandit lords, evil kings, or demigods. This book presents rules for over 200 monsters and villains, 45 traps and hazards, and seven companion NPCs presented with a low-level and mid-level stat block, making them suitable for play as adventuring companions or even pre-generated player characters all compatible with any Pathfinder First Edition game. Designed to work alongside the new Kingmaker Adventure Path campaign book, this volume makes quick conversion of the campaign to Pathfinder First Edition a breeze! Challenge your heroes while playing through the Kingmaker Adventure Path, or populate a campaign entirely of your own design!
