Fatal Falls is home to the biggest banger in all of Dead Cells, which is an unbelievably high bar. It's too bad that it's the theme of The Fractured Shrines, an area filled with so many hazards and deathtraps that you'll realistically never incorporate it into a run you hope to succeed in. Undying Shores is okay, at least, and the boss in The Mausoleum isn't too bad either.
