FINAL FANTASY X/X-2 HD Remaster guide · The sunken ruins Tidus explores with Rikku

After being rescued by the Al Bhed, Tidus is forced to dive with Rikku into sunken ruins to activate an ancient machina. You swim through submerged corridors, defeat a piranha swarm boss, and fight the fierce aquatic monster Tros to restore power. Once the generator is operational and you return to the salvage ship, the story progresses toward the island of Besaid.

Enemies

Piranha

Common aquatic enemy encountered in groups throughout the underwater corridors.

Sahagin

Weak to FireSteal / drop Potion

Fought in small numbers in the submerged halls before confronting the boss.

Tros

Weak to LightningSteal / drop Grenade

Tips

Use Rikku's Steal command against aquatic enemies and the boss Tros to stock up on Grenades, which deal reliable fixed damage during early battles.
During the battle with Tros, use the "Stand Ground" and "Pincer Attack" Trigger Commands when the boss moves far away to avoid its heavy rush attack and trap it between Tidus and Rikku.
