Party: Everyone in the canyon; Barret and Red XIII alone in the Trials of the Gi.
Key unlocks: The sky chocobo, Crystal Megaphone, Chakra, Ceremonial Staff, Mystic Collar and Calamitous Bazooka, and the Cave of the Gi.
Watch for: Equip Barret and Red XIII fully before the trials: Gi Nattak casts Doom.
1. The canyon
The observatory, the ceremony and the region.
-
1
The road in
Through Celestory Cavern from the airstrip. Kamaria’s ranch has the sky chocobo (optional, and Bonds of Trust needs it).
-
2
The observatory
Red XIII leads; the elevator up, the telescope and the phonograph. The treasury below has the Crystal Megaphone and Chakra.
-
3
The River of Lights
The ceremony, then the five conversations — Aerith, Barret, Tifa, Red XIII, Yuffie.
-
4
The region
Thirty intel that assume you glide, four quests, Bahamut Arisen, and Gears and Gambits for the protorelic. Ceremonial Staff behind the rest stop in the Village of the Gi.
2. The Trials of the Gi
Barret and Red XIII, and nobody else.
-
1
The statues
Ruby, amber and emerald statues to their altars; climbing walls between them. The Mystic Collar is picked up during the fetching; Calamitous Bazooka is in a purple chest on a lower ledge just before the first chain gate, once the three statues are placed.
-
2
The three gates
Chains and hooks, Gi Lancers in between.
-
3
Gi Nattak
No elemental weakness. Soul flames that curse and a Doom countdown: kill the flames, keep it pressured, and let Red XIII’s Vengeance handle the healing.
-
4
After
Cloud chases Gi Nattak, a Zack interlude, Yuffie through the village, and Cid’s Bronco Airlines for 300 gil to Nibel.
3. Bosses
- Gi Nattak: No weakness. Flames first, Doom watched, Vengeance for healing.
- Bahamut Arisen (optional): The canyon’s summon: particles that explode and a synergy-stripping attack.
4. Before you leave
Cross-checked
Cross-checked on 16 September 2026 against Game8’s Chapter 10 walkthrough (the observatory, the trials and the weapons) and PowerPyx’s boss guide for Gi Nattak and Bahamut Arisen. What is still unverified is the only thing reading cannot settle — nobody here has played it. Re-checked on 1 October 2026 against Vandal’s and EliteGuias’ Chapter 10 walkthroughs: the Calamitous Bazooka is before the first chain gate, after three altars, not five.
