Walkthrough
  1. 1
    Begin by slicing Ghost Fish with the Flails and collecting the RAPTOR DEITY statue to reveal the exit.

    Approach the Save Point and save your game. Find a Life of the Gods (OTG) in a chest to the far right.

    Search a dead body for a MAP. Continue down the path, using Explosive Arrows on Pincers and Ultimate Techniques (UTs) on Ariochs. Open a chest in the corner for another Life OTG.
  4. 4
    Objective: Find the Key of the Decayed Soul.

    Area: Palace Compound. If the door to the Imperial Palace is locked, return to the path and head towards the large gateway opposite the Palace.
  6. 6
    Upon reaching the gateway, defeat the swarming Ghost Fish with the Flails. Open the doorway to trigger a cutscene.
  7. 7
    Area: Stairway to the Imperial Palace. After the cutscene, search a dead body for an item.
  8. 8
    Before entering the Palace, consider pursuing the final Enemy Ambush for Karma Points.

    If needed, visit Muramasa's Shop to replenish stock before entering the Imperial Palace.

    Slice Ghost Fish and ascend the stairway. Open a chest for a Life OTG and enter the next doorway.
  13. 13
    Area: The Core - 2nd Floor. Defeat 2 Arioch Crabs with Explosive Arrows and 4 Ogres with UTs. Place the DEVIL DEITY statue on the mantle and exit. Equip the Flails and kill more Fish.

    Area: The Core - 3rd Floor. Face FOUR Knightmares. Use Dabilahro counters and evade Lava Pits. Place the SERPENT DEITY statue on the mantle and exit. Slice Fish and ascend to the fourth floor, but do not enter yet.
  15. 15
    Golden Scarab #50 / Life of the Gods #46. Jump off the ledge before the fourth floor entrance to find a smaller ledge below. Grab the Scarab at the end. Return to the fourth floor entrance and open the chest for a Life OTG.
  16. 16
    Area: The Core - 4th Floor. Defeat 5 Pincers, 1 Knightmare, and 1 Ogre. Prioritize the Knightmare. Use wall attacks on Pincers and UTs. Place the RAPTOR DIETY statue on the mantle to clear the Core. Exit and slice Ghost Fish in the stairway.
  17. 17
    Area: The Imperial Palace Core. Ascend to the top. Find two chests (containing Ghost Fish), a Save Point, and a TEAM NINJA prototype. Save your game. If you need to visit Muramasa's Shop, the closest is in Tairon. Enter the portal.
