expanding on my concept for twelve
it's an ice boss to represent the water element
9: fire (red background, red boss, explodes)
10: earth (green background, nuclear waste, green boss, earthy vibes n shi)
11: air (purple background, electrical boss, whirlpools, the boss teleports thru the air)
12: water/ice (cyan background, snowflake boss, freezes tiles)


very cool mockupand you fight twelve in the devil's tundra or something idk
