Boss Monster: Rise of the Minibosses introduces two new mechanics to the world of Arcadia!

Promotable Miniboss cards that permanently enhance Rooms and give you, the Boss, a new set of nefarious abilities.

All new Coins are earned from certain Rooms and used to promote mini-bosses and activate dangerous effects in other Room.

Rise of the Minibosses also includes new Bosses; new spells, and all new heroes, including a new group of challenging Dark Heroes and Hybrid Heroes.
