Final Fantasy X-2/Chapter 3/Airship Celsius

After the ending scenes from Chapter 2, the group is returned to the Airship Celsius. Buddy then reports that there has been a major outbreak of fiends. They have spawned in and overrun the temples. The girls decide to help contain the situation and put hunting spheres to the side for the moment. Besaid Island and Kilika become Hotspots. As does the headquarters of who you gave the stolen sphere to. Djose will become a Hotspot after you visit Besaid and Kilika, so best to visit there before if you want full completion.

If O'aka's debt has been paid it is also at this point that he will jump ship and set up shop at the Lake Macalania Travel Agency. This shop is the best one available in the game while O'aka's running it.

Chapter 3 is when many fiends become much more difficult. Many now have the ability to instantly inflict KO or status ailments. Use this chapter to level up some if you are having a hard time in battles. A new small enemy will also appear in random battles. Watchers. They seem harmless, only casting weak magic attacks but they have a higher purpose. Throughout Chapter 3 and 4, they record your actions and report them to the Bosses you will encounter in the game. What this means the bosses in story battles will adjust their fighting style based on is any action or ability you have used during a battle with a Watcher. Sometimes even developing an immunity or ability to lock a often used attack. To counter this, take the Watchers out first with regular physical attacks.

Travel down to the engine room to collect the chests for Phoenix Down x6, Ether x3, Remedy x5, and Hi-Potion x4. Then head up to the Cabin to rest and sell/buy items from Barkeep. When you are ready, you can either head on to the Hotspots to quickly get through the chapter or visit each place for completion points.
