Boss Monster 2: The Next Level

From BoardGameGeek:

The original Boss Monster challenged players to become the ultimate villains: video game-style Bosses. Now Boss Monster 2 builds on the original in every way! An all-new set of 160 cards, Boss Monster 2 is playable as a standalone game or as an expansion to the core set. Dark Heroes and Hybrid Heroes raise the stakes, while Epic Spells and "cycling" rooms give players more options and flexibility. Boss Monster 2 features everything that made the best-selling original a hit with players of all skill levels, with fresh new mechanisms and exciting new options. With more Bosses, more unique cards, and more ways to slay hapless adventurers, Boss Monster 2 will take your dungeon to The Next Level!
