From publisher blurb:
The Bonus Bestiary for D&D is here, expanding on the Midgard Bestiary for D&D with 12 additional monsters and foes drawn from Open Design's award-winning adventures and sourcebooks!
In these pages lurk some of the greatest monsters that Open Design has unleashed on players over the last five years - ready to deploy in your D&D adventures. All are core fantasy creatures designed for easy adaptation to any campaign.
You'll find lots of old favorites here along with brand-new monsters. 4th Edition D&D players now have a toychest that includes the Andrenjinyi, the Bagiennik, the Chort Devil and the Doppelrat, the Dragonleaf Tree and the mythical Kikimora, the disgusting Oculo Swarm, and the Salt Golem.
That's just for starters! There's also the Star Drake, Strangling Watcher, Stuhac, and the Witchlight, all fully illustrated and heavily playtested!
