Momohime's Final Boss is the toughest boss in the game. Before heading to the temple, gather some money and stock up on healing and soul restoration supplies. The path to the temple is extremely long, and you'll likely level up 3-4 times while making your way across. Once you get to the boss, immediately start hammering the two Doji. Once the 1st one goes down, a barrier should be removed, pulverize it at once. Make good use of the Windmill special move. When the 2 Doji turn into a small glowing orb, get to the side of the stage immediately, they can make a large explosion that can drain all you life in as little as 2 hits. Continue the process until the God falls.
