Final boss battle in Normal difficulty, with some key member equipped with Epic items = autobattle won it

Final boss battle in Hard difficulty, with some key member equipped with Epic items = autobattle lost because didn't use skills. I played it using the right skill and managed to win but for not much. I also tried with a worse equipment (Rare items and no Epic) and lost 3 times out of 4. I also tried Nightmare

I think SOTW fans will love this and even those who complained that Cursed Lands was too much on the easier side.
