Pits
After you win, the illusion will be destroyed but you are thrown into the darkness pit by Asura. This battle is weird to say the least.
There is the center enemy, which you can attack from all sorts of angles (but not the back). Attacking from the side is where you’ll get the best bonuses. Then there are six arms that attack you. If you get cute and try to clear them out you’ll get killed. Their assault is endless so it’s best to focus on the center enemy so that those 2800 HP can be taken down.
This is why you spent all that money forging your weapons, for those extra damage points. This battle of attrition will slowly go against you so you have to get your hacks in efficiently and heal when necessary. Group Heal is best but you’ll need Major Heal or Life at times. Keeping your heavy hitters like Goku and especially Cho alive is a must. This battle is pretty ridiculous in general considering the attacks you have to withstand.
After the battle the ending begins.

Have you ever wondered about Sanzo?
