New game+
After beating the game for the first time,on the title screen there will be new game+.This is a new game except your characters start with the items when you ended the game for the first time.
Easy AP
14 dresspheres, almost 200 abilities to learn and n AP needed. It will take much time, unless you combine two acessories (it have nothing to do with the alchemist dress): Key to Sucess and AP Egg. To earn the Key to Sucess, forget that the Guado exist. DON'T stop Garik from starting war against them, and also complete all missions in Moonflow (you won't be able to get the Baralay Sphere). The AP Egg will require a little work and luck: you must win it playing Blitzball in Luca, on Tournament mode (if it appear as the first prize: I've played 4 times and just now it appeared - and I have to face the Luca Goers!!!). The Key gives to the equiped person the Double All ability (since AP, EXP, Gil, to HP and strenght), and the Egg triples the amount of AP earned, what gives 6 AP per command, and used with non-lethal abilities (such as pray, bio, etc.) will be really easy to master all dresses. NOTE: It doesn't work with the special ones, since you lose all item-given abilities.
Capoeira Style Battles
No, I'm not talking about play with Eddie Gordo from Tekken 3. To see a Capoeira-like battle, you just need to equip Rikku with the Berseker dressphere. She will attack with Arco-iris move and perform some cool stunts.
The Perfect Ending
In order to get the perfect ending, you must complete each chapter with 100%. This means getting all items and completing all side missions and mini-games.
Instant Movie and Music Spheres
To instantly buy all of the soundtracks of the game you must start a new game. After you have completed the mission on Mt. Gagazet, do not go to the missions on Besaid Island or the Zanarkand Ruins, go straight to Luca. Complete the mission there, then go back. Go to the Sphere Theatre and you should be able to buy the music and movie spheres with whatever money you have.
Movie Spheres - 2,000 Gil
Music Spheres - 1,000 Gil
9999 damage
Okay, now for this to work properly you must have completed the game beforehand, you then go to New Game Plus and start again, now as you might no or not all your items and equipment are still there, though you still have to start at a low level, level 3. Now Yuna as gunner DressSphere, equip Cats Nip and Speed Bracer, I hope you have them or this wont work. Now damage Yuna in battle and do not heal her, so when you hit a enemy you hit 9999, and even better Trigger Happy 12 times, thats a total of 119988 damage aint that good! even better if you have break damage limit for a character. (Note: this will work on any of the three characters, I have just used te best way to deal the most damage).
