This is the fast-paced card game of strategic dungeon building! As a Boss Monster, your goal is to lure hapless adventurers into your dungeon and consume their souls. But beware! Your dungeon must be as deadly as it is enticing, or the puny heroes can actually survive long enough to wound you. More importantly, you have competition. Other Boss Monsters are all trying to outdo you with more precious treasures and more nefarious traps. Are you a bad enough dude to become the ultimate Boss Monster?
