Additionally, a blue and gold chest is dropped which grants permanent status bonuses when opened. A boss can only be defeated once in Rogue Legacy (excepting the non-traditional special rooms and items), and when each boss is defeated, massive amounts of gold is dropped in bags, coins, diamonds, and other trinkets.
Each time a boss is defeated, the grey icon that symbolizes a boss room is turned a bright cyan, showing it has been defeated. Set behind massive doors, these bosses are meant to challenge your mental and physical prowess, offering challenges above and beyond that of a regular enemy. Each region of the map in Rogue Legacy has its own boss, requiring various strategies and techniques to best them.
