From publisher blurb:
The Midgard Bestiary for D&D is here, with more than 150 monsters and foes drawn from Open Design's award-winning adventures and sourcebooks!
Between its covers 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 a homebrew campaign or another published setting.
You'll find lots of old favorites here along with brand-new monsters: foes and allies from the Free City of Zobeck, the empire of the ghouls, the courts of the shadow and river fey, the Old Margreve forest, and the Ironcrags.
4th Edition D&D players now have a toychest that includes the cave dragon, steam golem, ghost knight, imperial ghast, bonepowder ghoul, roachling, plus new demons, devils, and more, all fully illustrated and heavily playtested!
