Capture the Berserker

After completing “Find the Survivors” main Quest, you have to keep talking to Demons until one of them gives this quest. In my case, it was a gremlin in Naraku’s 6th stratum.

Wu Kong is found in Naraku’s 4th Stratum. There’s a shortcut from the 1st Stratum which can only be opened by the Key to Naraku which you’ll get during the “Capture the Black Samurai” Quest. It is the first door to the left in the first stratum. Upon reaching the 4th stratum, you should immediately spot a red demon form across the bridge. Make sure to have Demons with Ice attacks.

Wu Kong

Weak: Ice

Null: Phys, Gun

He will start the battle with Taunt. Be careful of his Crushing Wave since it will render the target with 1 HP. Just heal as necessary and you shouldn’t have problems defeating it. After critically injuring it, Wu Kong will run to a different floor. Fortunately, Burroughs was able to lock on the demon’s signal to make it easier for you hunt it.

Head to the 2nd Stratum to find him. Just refer to your map to find his location. Defeat him the second time around and he will run to another location again. This time, you’ll find him in the fifth stratum, outside the door of the Hall of the Minotaur. Defeat him for real and you’ll be able to fuse him in the Cathedral of Shadows.
