13th Age Bestiary
The macabre lich aristocrats of the Undying Peerage. The shadow dragon, which baits greedy adventurers with cursed treasure. The twygzogs, a genuinely weird new player character race of fungaloids. The intellect devourer, which can slip undetected into the party after eating someone's brain ... and be transformed by the experience to join the side of the heroes.
The 13th Age Bestiary is invaluable for 13th Age GMs. For customers who haven't yet discovered 13th Age but love monsters and unique, exciting battles, the innovative monster mechanics and storytelling hooks are a great showcase for the strengths of the core game.
