We may have to remove the Nurse from the game.eh, boss is still easily cheesed with auto-pause + nurse
build a roof about 20 blocks long or so, put the nurse in a small room at the end, and have the rest platforms to walk on.
Use Nebula armor with nebula arcanum/razorblade typhoon the hands and head, then use last prism for the core. For accessories, stick with celestial cuffs and frozen turtle shell. every time you drop low, just walk to the nurse, pause, then click on her for cheap heals. then go back to bashing the boss's brains in.
