    In the Blue Eye Chamber, kill the nearby Archer and grab Arrows from the dead body.

    Go down the stairs, use the broken pillars for cover (press the cover button to crouch behind walls or objects), and shoot the Archers with Arrows.
  4. 4
    Return upstairs and shoot the glowing Medallion on the upper wall to reveal a pathway.
  5. 5
    Make your way down the pathway, avoiding the pendulums. You can shoot the medallions above the pendulums to slow them down.
  6. 6
    Use a Wall Run at the end of the path to reach the Blue Eye Button and press it to unlock the large door outside.
  7. 7
    GOLDEN SCARAB #19 is under the platform in the Blue Eye Chamber. Jump down and grab it.

    BOSS BATTLE: HYDRACUBUS PART 2. On Hard Mode, Hydra will have one Kiyatt assisting him; killing the Kiyatt will cause another to spawn.
  10. 10
    After the battle, grab the Lives OTTG item left by Hydracubus to increase your life bar.

    Exit back to the Suspension Bridge Room. New pillars will emerge from the walls. Use a continuous Bird Flip to reach the top of the room.
  12. 12
    If you haven't crossed the bridge earlier, you can now cross it back to the previous Save Point.
  13. 13
    JEWEL OF THE DEMON SEAL #1 is on the throne seat at the other end of the room. This item upgrades your Ninpo Scroll.
  14. 14
    Continue down the walkway to the Great Corridor and reach another Save Point. SAVE your game.
  15. 15
    Descend the corridor to encounter Archers and Zombies. Destroy them with combos and UTs (Ultimate Techniques).
  16. 16
    Search a nearby dead body to find the ART OF THE ICE STORM Ninpo Scroll.
  17. 17
    Continue down the corridor to the Chamber of Everlasting Sleep.
  18. 18
    At the entrance, use Flails to thin out the Ghost Fish.
  19. 19
    Enter the Chamber and go to the left ledge. Use a Wall Run to land on a large step button.
  20. 20
    When the step button lowers, access the coffin to grab the WOLF DEITY Statue and the SKULL KEY.
  21. 21
    Use the SKULL KEY on the nearby door and head down the pathway.
  22. 22
    Kill the Ghost Fish in the cavern and continue until a cutscene (a non-interactive cinematic the game plays automatically) occurs.

  30. 30
    Exit the Monk's room and head for the Altar Hall to face Alma.
  31. 31
    ENEMY AMBUSH NOTE: If you have not attempted the ambush in the Archives Room, do it now. Once you defeat Alma, the ambush in the Archives Room is forfeited.
