From the publisher's website: The True20 Bestiary is the monster book with a foe for every occasion. Say goodbye to pages and pages of flavorless numbers and useless minutia. True20 stats are lean and compact and that means this book can really pack the creatures in. Inside you'll find fantasy staples, eldritch horrors, bizarre aliens, and more. While fantasy is the focus, you'll also find opponents suitable for horror and scifi campaign settings. Illustrated to Green Ronin's usual high standards, the Bestiary is an indispensable sourcebook for the True20 Adventure Roleplaying RPG.
