From publisher blurb:
Brave adventurers scour the dungeon in search of treasure, but around the next dark corner something terrible and hungry awaits them. What will it be this time?
This Dungeons & Dragons core rulebook contains a horde of monsters to unleash upon your campaign world. It includes monsters approporiate for all levels of play, heroic, paragon, and epic. Terrorize your players with such classic creatures as silver dragons, frost giants, and rust monsters. Threaten them with new variants of existing 4th Edition monsters, including new beholders, demons, and lycanthropes. Surprise them with never-before-seen monsters such as the star spawn, the witherling, and the chaos shard. Your D&D game will never be the same!
