Luca

After watching Grand Maester Mika arrive at the next dock over, you will have to play blitzball. You should pay attention to the tutorial, which will most definitely help you in the game to come. Yuna then decides she wants to go see Auron, who she has heard is currently in Luca. However, before doing that, you should get all of the items which can be found in Luca. The Al Bhed Primer vol. VI is behind a player in the opposing teams locker room, and at the end of that hallway there are two Hi-Potions. At Dock 1 you will find O'aka, with a quite intimidating list of things to buy and if you search around you can find 600 Gil and a Tidal Spear. At the dock where you started out you will find two Phoenix Downs in a chest. At Dock 5, if you search the back carefully you will find a Magic Sphere and a HP Sphere. On the other side of the stadium, on a bridge, you will find the Sphere Theater. Inside there are two men, one selling Music Spheres and the other selling Movie Spheres. If you talk to the people there you can find out how to use them. However, you should postpone buying them, for they do cost a pretty penny. If you keep going along that bridge you will eventually end up in a place that resembles a marketplace. There is a shop that sells metal armor here. Now, head up the stairs to the right of the café, and don't miss the chest with 1000 Gil. Keep going and you'll find Luzzu and Gatta. After a short conversation, head to the café. Inside, you'll find not Auron, but instead a battle between Kimahri and some Ronso friends of his. Then everyone realizes that Yuna has been kidnapped. She has been taken to Dock 4 by the Al Bhed. Along the way you will find quite a few Workers. Lulu can easily get rid of them with Thunder. Once you arrive at Dock 4, you will engage in a seemingly endless battle with Workers. After that ends, go down Dock 4 and to the ship. Once you party jumps upon it you will have to battle the Oblitzerator.
