Walkthrough
  1. 1
    In the first room of the ancient ruins, find a chest with 2 Ethers in the northwest corner.
  2. 2
    Proceed east, as the north path is blocked by a door.
  3. 3
    Engage in your first random encounter. Learn about pre-emptive strikes (start with one Momentum Charge and full ATB) and side encounters (start with half ATB and Momentum). Finishing enemies with Momentum yields better spoils.
  4. 4
    After the first fight, go north and up stairs to the east.
  5. 5
    Find a switch to the right of a locked door to open it.
  6. 6
    Enter the next room, grab the sparkle item, and proceed north, ignoring the locked door to the west.
  7. 7
    Defeat enemies, drop off the ledge, and grab the item above you.
  8. 8
    Go south, clear the room, and use the lever on the east wall to open the previously locked door, creating a shortcut.
  9. 9
    Continue west and enter the room to the north. Find a chest in the northeast corner containing the Autobow, a new weapon for Locke.
  10. 10
    Follow the path until it splits. Head west to find a sparkle item in the southeast corner of the room.
  11. 11
    Back at the fork, head east. Use the switch before the entrance to the room to open the door blocking the south path, creating a shortcut back to the ruins entrance.
  12. 12
    Travel west to find a save point, indicating an upcoming boss battle.

BOSS - Guardian

The Guardian is a large boss that moves quickly. Its attacks include Punch, Rear Punch, Hammer, One-Two Punch, Rear One-Two, Triple Strike, and Rear Triple. Rear Triple can potentially one-shot characters on Hard difficulty.

Strategy:

  • Manage your health carefully, keeping it above 80-90% during double attacks and full health during triple attacks.
  • Spread out your characters to avoid small area-of-effect (AOE) damage.
  • Be aware of critical hits, which make its multi-hit attacks even more dangerous.
  • Use character skills, such as Lumina's for extra turns and Locke's for increased damage.
  • Aim to finish the Guardian with a Momentum Charge for better spoils.

After the Boss:

  1. After defeating the Guardian, you will receive a Passion Memory and a Mech Key.
  2. Check the east side of the room for a sparkle item.
  3. Open the locked chest in the northwest corner with the Mech Key to obtain the Mech Tekko, a new weapon for Lumina.
  4. Inspect the monument and hold Square to create the Founder Memory.
  5. Backtrack to the entrance and return to Elgarthe.
  6. Use memories to restore Elgarthe.
  7. Prepare to leave for Mistral Gorge.
