Walkthrough
  1. 1
    In the exterior area, find a dry spot on the eastern edge. Look for a glyph and a chest containing 200 Gil to the north.
  2. 2
    Head west to find a sphere that allows importing Al Bhed Primers from other save files. South of this sphere is a chest with two Potions.
  3. 3
    Proceed north to the next area. Use the Save Sphere (a sphere used to save your progress).
  4. 4
    Follow the ledge until it forks. Take the western catwalk to find a Hi-Potion.
  5. 5
    Return to the fork and go north for a scene (a non-interactive story sequence).
  6. 6
    Swim downward and west for another scene, followed by a battle against two Sahagins.
  7. 7
    After defeating the Sahagins, the boss Geosgaeno will appear.
  8. 8
    After the Geosgaeno battle, proceed through the Corridor to the next room (Interior).
  9. 9
    In the Hall & Stairs area, a scene will play. Use the Save Sphere.
  10. 10
    Use the nearby door and examine a ruined desk to find a piece of Flint (a Key Item, an important item for story progression).
  11. 11
    Attempt to use the eastern door, then go south along the wall to find a chest containing an X-Potion.
  12. 12
    Use the northern door.
  13. 13
    In the narrow stairwell, find a hidden chest containing an Ether.
  14. 14
    At the top of the stairs, examine a vase to obtain a Withered Bouquet (a Key Item).

    Continue along the linear path to find a chest with a Hi-Potion on a balcony.
  16. 16
    Return to the main level and save if desired.
  17. 17
    Examine the campfire for scenes.
  18. 18
    After the scenes, you will face the boss Klikk.

Boss: Geosgaeno

Geosgaeno has 32,767 HP. It cannot be defeated; attacks that would reduce its HP to zero will instead set it to 1 HP and prevent further damage. The battle ends after three turns. Geosgaeno cannot kill you, as each hit divides your current HP by half. Do not waste items; simply attack until the battle concludes.

Boss: Klikk

Klikk has 1,500 HP. Tidus will receive help when Klikk's HP drops to half or after Tidus has taken five turns. Klikk uses a basic physical attack. After receiving help, a character named ???? can Steal Grenades and use them with the Use command, dealing around 300 damage each. Klikk drops two Ability Spheres, or four if Overkilled (possible with an Overdrive or critical hit with a Grenade). There is a 25% chance of dropping a blank Weapon with no slots. You will receive 5 AP (7 for Overkill) and 50 Gil.

Tips
  • Use the minimap (a small map displayed on the HUD (heads-up display — the on-screen icons showing health, ammo and the minimap), or Heads-Up Display, showing your immediate surroundings) to navigate narrow paths that may be difficult to see.
  • For the Geosgaeno fight, focus on surviving and letting the battle timer run out, as it cannot be defeated.
  • For the Klikk fight, wait for assistance before using powerful attacks or items. Stealing and using Grenades is highly effective.
  • Overkilling Klikk requires an Overdrive or a critical hit with a Grenade.
  • Exterior: 200 Gil, Potion ×2, Hi-Potion
  • Interior: Flint (Key Item), X-Potion, Ether, Withered Bouquet (Key Item), Hi-Potion, Grenade ×2
  • Klikk Battle: 50 Gil, 5 AP (7 for Overkill), 2 Ability Spheres (4 for Overkill), 25% chance of a blank Weapon drop.
