Defeated the last Boss (Sin)
The last boss in this game is very weird one. The size is so small, but the power is so cool. When the battle begin, cast 'Reflect' magic on it, because it will use 'Full-Cure' on it after each attack which cure 9'999 HP. When you reach Yuna's turn, cast 'Reflect' on all party members too. Use Tidus and Auron to attack and use Yuna's 'Holy' to attack it.
Al Bhed Primers
There are total 26 Al Bhed Primer. This book contain a complete alphabetical words in Al Bhed translate into an alphabetical words. So if you can complete all 26 Al Bhed Primer you can understand what the Al Bhed tribe said to you. The Al Bhed word is highlight in red instead of blue.
Cactuar Locations
There are total 9 Cactuar that can be found all around the world. The location of the Cactuar are:
Oasis:
Near the first Save point
Sanubia Desert (East):
In the alcove to the east, north of the tent with the save point
Sanubia Desert (West):
Search the sign near the Cactuar rock that says “20% off”
Sanubia Desert (Central):
Near the ruins to the west, look for two Cactuars running around the desert.
Sanubia Desert (East):
Near the save point under the tent.
Sanubia Desert (West):
Trapped in the treasure chest in the far west.
Sanubia Desert (Central):
Inside one of the sand whirlpools. You must exit and re-enter the area.
Oasis:
Teleport back to the airship and go on the outside deck.
Sanubia Desert:
Return to the Cactuar statue and the last one automatically appears behind you.
Overdrives
Auron: Find different Jeckt Spheres laying about the world. Some of these will give Auron a new Overdrive. You need to find all ten to get Auron's final overdrive.
Kimari: Use the Dragon Sword ability to drain HP and MP from the enemy. If the enemy has a Blue magic skill that Kimari can learn, he will gain it automatically. The only one that is difficult to get is "Sunshine", which you obtain from the Omega Weapon.
Lulu: Rotate the Right Analog-stick clockwise as fast as possible. The number will go up the more you rotate it. The more you level Lulu up, the easier it is to cast multiple spells.
Rikku: Rikku's overdrive combines items to create special attacks and power-ups during battle. You have to choose any two items to combine. Note: Two of the same kind will work.
Tidus: Just keep using them over and over. After a while, he will learn his next Overdrive.
Wakka: You can win new overdrive roulette (slots) types in the Blitzball Ranking and Tournament modes.
One of the Best Blitzball Shots
On the S.S. Winno you will get the Jecht Shot Challenge. If you pass it you can use the Jecht Shot in blitsball when you pass level 3.
Easily Defeat Guado Guards
Any time you are facing Guado Guards (such as against Seymor the first time). They always auto-potion when you hurt them. The easiest way to beat them is NOT to summon aeons, but insetad to have Rikku steal thier potion. It only takes one steal and then they can't auto-potion anymore.
Very Easy Win with YuYevon
I am not saying the boss is easy, but if you manage to make it passed all your summons and you fight Yu Yevon this is what you do. No matter how much you hit him he uses Curage and heals 9,999. So use a reflect on him and hit him. He will heal you 9,999 almost every hit he takes.
Steal From Chest's Without Fighting Mimics
Later in the game you will incounter treasure chest's during battle. Some of these chests have nothing in them and as a result you have to fight a powerful mimic. But there is away around this. First make sure Rikku (or anyone) has the ability "Mug." When in a battle with a chest, use mug on the chest, if the chest has an item, you get it and kill the chest. If not, you get no item and kill the chest. Since chest's have 1 HP this is a great way to avoid mimics.
Get tons of AP
To get a lot of AP any time after you kill Seymour the 1st time just return to Macalania Temple and fight the Guado.
Get the NO AP Ability Off Your Legendary Weapon
To get the NO AP ability off your ultimate weapon , you must collect the correct crest and sigil for the weapon.
Lots of Potions
While riding the S.S. Liki, go to the bottom deck and enter the first door to your left. in the Room their should be a brown briefcase on the floor, kick it 15 times and you will get 15 potions.
More Potions
On the USS Likki, the first time you get on there, go down into the lower part of the ship and enter the room with the two Besaid Aurochs. After getting the chest in that room, go up to the suitcase and press 'X'. Tidus will kick the suitcase and get a potion. Keep kicking it and the suitcase will give you more and more potions until it totally runs out.
Defeat the Aeons
You must do this before fighting the last boss because the boss (Sin) will enter your summon body to take over the body. So, you must kill all your summon to fight the last boss. This battle will be easier if your summon don't get to their highest power.
Easy Blitz-Ball moves
To learn Blitz moves faster just set your marks on the move you want... now when playing dont worry about setting your players to "mark mode". You don't need to as long as they use their Blitz move you can copy it! Now your players wont run from their positions when in "mark mode".
Secret Place Coordinates
When you have an airship, talk to Cid, and choose the second option in Map menu (Search). The secret place are:
Secret Place #1 X: 34 Y: 58
Secret Place #2 X: 15 Y: 41
Secret Place #3 X: 31 Y: 73
Secret Place #4 X: 16 Y: 57
Secret Place #5 X: 42 Y: 57
Secret Place #6 X: 74 Y: 36
Healing Aeons
To heal all of your aeons at once just save the game.
Win The Blitz Ball Tournament
If you win the first tournament at Luca, you will get a trophy and a weapon for Wakka. If you lose, the game will continue but only have the trophy.
Huge AP
To earn Huge AP you need to have done a couple things; first it’s preferable that you do the Cacter quest to find Cacters (little green guys that look like walking cactus’s) easier. Then you need to have 10 x Doors to tomorrow (Doors to tomorrow can be stolen from Omega Weapon 10 each steal; or bribed from Mech Leaders for 74,000 gil avg. 2 each steal, or Mech Scouts for 55,000 gil Mech Leaders give more, they are found on mt. Gagazet. Once you have done this customize the weapon of a character that you wish to acquire Huge AP and add to his/her weapon Overdrive->AP ability (if possible try to have both Overdrive->AP and Double AP/ Triple AP on your weapon as well) it takes 10 Doors to tomorrow to add the Overdrive->AP ability on your weapon. Once you have gone through these steps you need to go find some Cacters; once in a battle with a Cacter you need to have one player with Provoke and the other 2 with haste on themselves. If the player with the Overdrive->AP ability on his/her weapon has Provoke then set their overdrive to Stoic, and if not then set it to comrade. (Hint; when in the start of a battle with Cacters don’t waste any moves by pushing triangle, because Cacters are fast and tend to flee easily). Provoke at least one Cacter so it doesn’t run away; when in battle try to minimize your enemies down to one Cacter; once a Cacter is provoked he will use 10,000 needles when it is his turn to attack, and killing who ever he uses it on, then quickly use a phoenixdown on your KO’d party member and provoke all over again. You will notice that the character with Overdrive->AP does not gain any overdrive for an attack; this is because all the overdrive points are going to AP. If you use about 7 phoenixdown’s your character will have acquired around 250,000+ AP once done each battle. I have proved this and I’ve successfully unlocked every sphere on the sphere grid for Tidus. If you have questions please E-mail me at yanni_456@hotmail.com I’d be happy to answer any questions and receive comments.
Blitz Ball Cheat
If you are having trouble with any of the teams in the blitz ball then you should try this little tactic. Try really hard to score one goal against the opposing team.Then the match will start out again and the opposing team will have the ball. Once you encounter the enemy with the ball try to get the ball off him/her. If you didn't get the ball off him or her then try again next time you encounter the person with the ball. Once you have finally got the ball quickly pass the ball to one of the two people that defend your goal (not the goal keeper) and run all the way into a corner thet you are closest to that is not gaurded by an opponent. If there is an enemy in the corner then pass the ball to the other defender and run into that corner. If both of the defenders are marked by enemies then pass it to another unmarked player, wait till the enermies slowly close in on you and then quickley pass the ball back to one of you defenders. Then all you have to do is wait in the corner for a while until your time is up and you should be at half time. After half time the match should start and either you or the opposing team will have the ball. if you have the ball then just pass it to your defender and go and sit in a corner if not then get the ball off the oposing team, pass it to a defender and then go sit in a corner until the time is up. If you have done this correctly then you should have won the match. This works nearly every time and I have won all of the reels for wakka and have also won wakkas sigil.
Super Mega AP
This cheat is exactly the same as the huge ap one except that you fight the cactua king in the monster arena. Go to the monster area in the cal lands and buy a weapon off the guy that has the capture ability. then go to the thunder plains and capture one of each of these monsters. Melusine, Aerouge, Buer, Gold Element, Kusariqqu, Larva, Iron Giant and a Qactuar. It is easier to catch Qactuas once you have activate the Quactua stones. One you have done that equip your weapon the same one that is said in the huge ap cheat go to the calm lands. go to the monster arena and fight the cactua king. Let the cactua king attack one of your charachters and then use a phoenix down to heal that charachter and repeat this process untill the cactua king runs away or you can flee the battle whenever you want. I have done this with Rikku And tidus and have gotten 5million ap in one hit.
Items
After your ship docks at the first town (the one torn apart by Sin), proceed through the intermission sequence with Yuna, and you will find yourself in a hut. Exit the hut, and proceee to the left side of the screen. You will see a child on a pile of rubble. Press X near the child to rescue her before the rubble collapses. Proceed to the hut at the top right of the current screen for a free item from the chest.
Items from dodging lightning
In the Thunder Plains, if you can dodge the lightning a certain number of times in a row, you will be rewarded with items. Additionally, if you get struck by lightning 30 times, you get an Ether. If you get hit 80 times, you get an Elixir.

Legendary Weapons
Each Legendary weapon must be acquired by using the Celestial Mirror.
Tidus: Caladbolg
Race and defeat the Chocobo trainer in the Calm Lands. After winning the race, walk to the upper northwest section of the Calm Lands. The guard blocking a narrow pathway down into the gorge will have left his post, allowing you to pass. Tidus will then be able to use the Calastial Mirror to acquire Caladbolg.
Yuna: Nirvana
Capture all nine types of fiends in the Calm Land region. After collecting them all, return to the monster arena owner. He will produce a treasure chest, containing the weapon.
Auron: Masamune
Acquire the Rusty Sword, which is found on the eastern cliff of the Cavern of the Stolen Fayth in the Calm Lands. Take the Rusty Sword to the statue of Lord Mi'ihen on the Mushroom Rock Road. Place the Rusty Sword before the statue to reveal a glyph. Touch it to reveal the Masamune's secret location.
Wakka: World Champion
Talk to the bartender in Luca Cafe. If she refuses to turn it over, it is because you have been neglecting to play Blitzball.
Kimahri: Spirit Lance
Active three of the Qactuar Stones on the Thunder Plains, then find the Qactuar ghost flying just above the ground at Thunder Plains-South. Follow it to a small ruined lighting tower on the right side. Press Square to send a bolt of lightning to the tower to reveal a treasure holding the weapon.
Lulu: Onion Knight
Return to Baaj Temple and dive underwater. Swim towards the doors to the north and fight Geosgaeno. After defeating it, search the southern part of the circular underwater area and look for a treasure chest containing the weapon.
Rikku: Godhand
Input the airship password, "GODHAND" to open a secret location at Mushroom Rock. Move north to the end of this ravine, and use the Celestial Mirror on the symbol embedded in the rock face.
Caladbolg Power Up Items
Item #1 (Sun Crest)
Can be found at Zanarkand dome when you fight Yunalesca.
Item #2 (Sun Sigil)
Can be obtained after you beat the Chocobo trainer at Calm Land with time 0.0.0
How to get the ultimate weapon
Each character has a specific ultimate weapon that can be acquired by using the Celestial Mirror. When the weapon is first found, it is equipped with No AP ability. To remove this ability and empower the weapon to it's full potential, you need to find 2 specific event items for each character. Upon doing so, you must then return to the Macalania Woods and use the Celestial Mirror to power up the weapon at the large spherical crystal high amid the treetops. Below is the description on how to get the weapon.
Restoring Ifrits Health With Out Saving
Summon Ifrit, then when you get low on health go into his black magic and use fire on himself, that should restore some of his health, since he came from hell, also, when your battling two "bombs" and another foe, kill the foe first, that way when the foe hurts you you can let the bombs hit you since the always use fire.
Easy potions and spheres
Its not really a cheat, but after Tidus is rescued from the ruins by Rikku and her Al Bhed family and friends, you will be prompted to dive off of the ship and enter the airship. The guard closest to the save sphere will give you x3 potion when you talk to him. If you dive and return to the ship after leaving the screen he will give you another 3 potions. Its an easy way to build up potions as well as recieve spheres from the fish in the water. You can also take this opportunity to steal grenades for later use in the game.
Ultimate AP Gaining Trick
*NOTE: You'll need the airship for this trick! First, you'll have to get "Capture" weapons from the Monster Arena guy in the Calm Lands. You'll also have to catch all the monsters in the Calm Lands in order to be able to fight the monsters you catch in other areas. So, when you finish catching all of the monsters in the Calm Lands and the "Fight Monsters" option appears when you talk to the guy, go to the Omega Ruins (X: 72 Y: 34 on the "Search" option in the airship menu) and catch a Master Tonberry. Once he's caught, go fight him in the Monster Arena for 30,000 AP per battle. If you have Double AP or Triple AP on your weapons, you can get 60,000 or even 90,000 AP in one battle!! If you continuously do this for a while, you can get some SERIOUS Sphere Levels. I did this and have about 30,000 HP on all of my characters, along with stats in the 200's.
Defeat Yu Yeven Easier
Customize one or all of your characters' weapons with the ability "Zombie Strike" and attack Yu Yeven with it. He can be turned into the zombie status. Then with the same or another character use a "Pheonix Down" or cast "Full-Life" on Yu Yevon. This will instantly kill him. It worked for me. His health is about 99,999,999 so have fun with this code and even steal items from him before you kill him.
Have Reserved Weapons and Armor
Every character should have an armor piece that is resistant to all four elements and another that is resistant to bad statuses like poison and silence. Also every character needs to have at least one piece of armor with the break HP limit, auto-regen, magic defense + 20%, and defense + 20%
Every character needs a weapon with the triple AP ability also you may want to create weapons for each character that inflicts status ailments like death or poison.
Gain Gil in the Monster Arena
Simply have one of your characters equip a weapon with the gillionare ability (must have at least 30 designer wallets) and you will even gain gil in the monster arena.
Unlocking Nemisis and Ultima Buster
To be able to fight Nemisis you must catch 10 of every monster in the world. To be able to fight Ultima Buster you must catch 5 of every monster in the world.
Defeating Nemisis Easily
First and foremost you must have agility, magic, strength, defense, and magic defense at 200+ First off cast hastega, protect, and auto-life,(don't worry about casting shell). When attacking Nemisis always use Quick Hit. Attack with your party untill Nemisis uses its cannon on you after he uses the cannon he will attack with either Armaggedon (which causes 99,999 damage to all characters) or his buster attack (which causes 30,000 damage to all characters). Summon an aeon right after he uses the cannon attack against you, but be aware as sometimes Nemisis can use one of those two powerful attacks without warning at anytime that is why auto-life is needed. Unless his first attack after the cannon is Armaggedon after sacreficing an aeon return to your normal attack pattern using Quick Hit. If he uses Armaggedon then summon another aeon before he attacks again as he will use the Buster attack. Nemisis shouldn't take to long to beat just keep using Quick Hit and time his attacks correctly. Stay focused because one mistake in this battle can cost you dearly. Also don't use overdrive attacks against Nemisis he will counter with Ultima. If you want to steal an item from him use mug because he will also counter a normal steal attack.
Masamune Power Ups
The Crest for the masamune is found south of the Oldroad at Mi'hen Highroad. The sigil will be given to you if you capture 10 monsters, 10 different spicies, and 10 different regions.
Aurons Secret Weapon and Aurons Sigil And Crest
First, you must get the rusty sword from the gorge by the cavern of the faith(not in the cavern of faith). Then, you must take the rusty sword to mushroom rock road and incert it by the statue. It will reveal the swords location. The Crest is found south of Oldroad at Mi'hen Highroad. The sigil is given to you when you capture 10 monsters, 10 different species, and in 10 different regions.
Gil Gil and more Gil
In the Omega Dungeon you will sometimes face a lone lizard with a treasure chest steal from the chest. You will sometimes get a mega-potion or a turbo-ether which are great items, but I would rather get nothing ang fight a mimic because they give you 50,000 Gil and 100,000 Gil if you have the Gillionare ability.
Defeat Aeons
Get Auron to where he does 9999 so he kills the aeons 1-hit.(You will be forced to fight your aeons.) So you can power up your aeons all you want.
AP cheat
Usually when you verse a tough opponent like seymour 1st you will be allowed to go back out of the temple and fight some fiends. When you beat the fiends you will obtain some AP.
Defeat Guado Gaurds
To beat the guado guards when figting Seymore 1,have Kamiahri's overdrive be full. Then use his overdrive stonebreath. That should kill the guards in one hit.
Hidden Aeons
Yojimbo: In the Calm Lands, circle past the right side of the bridge leading to Mt. Gagazet, and descend into the gorge below. To the left of the Save Sphere is the Cavern of the Stolen Fayth. Proceed through the cave until you encounter a spirit. Defeat Yojimbo and speak to him to negotiate a fee for his services.
Anima: Go to Baaj Temple with the Airship. Dive into the water and fight Geosgaeno. Defeat it and swim toward the underwater temple entrance. Approach the six statues on either side. There is one hidden item in each of Spira's six Cloisters of Trails. You should have five of these items, now get the last one from Zanarkand Dome. Solve the puzzle there and return with the last item and get your prize Aeon.
The Magus Sisters: Capture all of the required types of fiends on Mt. Gagazet and return to the monster arena and get the Blossom Crown. You must possess all other Aeons, including Yojimbo and Anima. Next, go to Remiem Temple. Defeat
Spathi, and receive the Flower Scepter. After defeating all of the Aeons at Remiem Temple, use the Blossom Brown and the Flower Scepter on the door in the back to unseal it and acquire the Magus Sisters.
Cure ixion, shiva and ifrit
For ixion cast thunder, thundara or thundaga on himself.
For shiva cast blizzard, blizzara or blizzaga on herself.
For ifrit cast Fire, Fira or firaga on himself.
Easy Full Overdrive
Activate the tutorial console and select "Fiend Info". As the battle goes on, call an Aeon. When the Overdrive gauge is full, use an attack other than the Overdrive. After the battle ends, you Overdrive gauge will be full.
Go to Monster Arena in the Calm Lands. Buy weapons with the Capture ability. Capture all monsters from all areas, then go back to the arena and talk to the man. He will give you a lot of items, then he will say that he has created a monster. He will ask if you want to fight it for free. Answer "Yes". The monster is called Catastrophe. When you fight, it will release an attack called Poison Breath. It will do over 10,000 damage and all of your characters that are fighting will die. However, your Overdrive will either be full or very close to being full.
Go to the Monster Arena in the Calm Lands. Set all your party members' Overdrives to "Stoic". Preferably, battle a created monster that can easily kill a party member with one hit. Have at least Auron and Yuna in your party if you do not want waste a lot of gil. Have Auron use Guard on Yuna and have Yuna use Life on party members. Then, switch the party members until each one has been killed.
Note: You must have the Slayer Overdrive and the airship in order to do this trick. To get very easy Overdrives, set the designated character to Overdrive mode Slayer. Then, fly to Besaid or Djose Road. Battle the fiends there. They hopefully will be easy for you to defeat, and you will get your overdrive faster.
Use the airship to go to Guadosalam. The Inn you are in will have a Tutorial Monitor. Select "Fiend Info" and battle Iron Giant. Call all of your Aeons and have them use Boost. The Iron Giant will miss every time. Then, use your characters to kill it. In five minutes you will have all Aeon Overdrives full.
Note: Equip the Victory Overdrive ability and Double Overdrive. Fly to Besaid in the airship and fight. You should have all your Overdrives in about two battles.
Set the Overdrive to "Stoic" and go to the Monster Arena. Fight Master Tonberry. When the fight starts, hit Master Tonberry with the person whose Overdrive you want to fill. The Overdrive should be filled in one hit. You will most likely die when he counterattacks.
If you want to get Tidus' Blitz Ace Overdrive, have him in the party almost every time you kill the last monster. You should eventually get the Victor Overdrive mode, which puts in one fifth of your Overdrive gauge after every battle. Then, go to a location, such as Besaid, and fight enemies. Kill them quickly. The Overdrive will charge up five battles later.
Set your Overdrive mode on Warrior. You must have the Break Damage Limit ability and Ultima magic. If your magic status is more than 200 or is 255, fight with three or more enemies in a battle. Use Ultima at the start of the battle. Your Overdrive gauge will rise very high.
When against fighting the Magic Urn in the Cave Of Stolen Fayth, just defend. It will not attack you. However, you will have to set your Overdrive to "Ally".
Hint: Kimarhi's Overdrives:
Jump: Standard
Seed Cannon: Ragora species (Kilika Woods)
Aqua Breath: Biran and Yenke Ronso (Mt. Gagazet), Chimera species (Macalania Woods, Home, Calm Lands, Monster Arena)
Stone Breath: Biran and Yenke Ronso (Mt. Gagazet), Basilisk species (Djose Highroad)
Bad Breath: Malboro species (Calm Lands, Omega Ruins
Thrust Kick: YKT species(Bevelle, Zanarkand Ruins)
White Wind: Biran and Yenke Ronso (Mt. Gagazet), Dark Flan (Mt. Gagazet Caves)
Mighty Guard: Behemoth species (Zanarkand, Sin, Monster arena)
Fire Breath: Biran and Yenke Ronso (Mt. Gagazet), Dual Horn (Mi'ihen Highroad)
Self Destruct: Bomb species(Airship, Mi'ihen Highroad, Mt. Gagazet, Omega Ruins)
Doom: Biran and Yenke Ronso (Mt. Gagazet), Ghost species (Cavern of the Stolen Fayth)
Speak Perfect Al Bhed At The Start
Play through and collect all the Al Bhed Primers, then save the game. Start a new game. At the point where Tidus first arrives in Spira, he is in the water with a bird on it. When he can move, swim over to the left of the screen. Over on that side is an Al Bhed Compilation Sphere. Make sure that you have the same memory card in that your first game was saved to. Touch the sphere and have it compile the Al Bhed dictionary. Check your key items. You will now find that you have every single Al Bhed Primer that you found in your first game. If you found all 26 of them, you will be speaking perfect Al Bhed, even before meeting Rikku for the first time. Note: If this is done, all the Al Bhed Primers will disappear from the "new" game, as you will already have them. Also, you can roam and get every single Primer in the game except for XXII, which is in the Temple Of Bevelle -- If you did not get it the first time around, you will have to wait until you can get it in the second game. All other Primers can be found at any time in the game.
Defeating Defender Z
To defeat Defender Z in Zanarkand Ruins, you need Tidus' Provoke. Use Provoke, and after that just attack normally with other party members. After being provoked, the only thing he will do is a Blast Punch attack to Tidus, and it will not kill him. It will only damage half of Tidus' HP on every attack.
Easy AP
This trick requires a Friend Sphere or Teleport Sphere and Rikku on your team. Use a Teleport Sphere or a Friend Sphere to get to where Rikku starts out on the Sphere Grid. Because she starts out with such low HP, the sphere grid has to give her a lot of HP Spheres. Getting other characters there will add at least 1000 HP.
Collect some Doors Of Tomorrow, either from the first weapon in the Omega Ruins or from the Battle Arena by capturing enemies. Then, gain the ability Overdrive -> AP. Return to the Battle Arena and choose the character who has the weapon with that skill. It is best to have three characters with it for easier levels and to save time. Set the character's Overdrive mode to "Comrade" then choose to fight a King Cactaur. Note: You must have captured all the enemies from the Thunder Plains in order to unlock King Cactaur. In the battle the King Cactaur will use either 10,000 Needles or 99,999 Needles (better). Keep using Phoenix Downs or a Life spell to bring back the character he kills. He will eventually run away and the battle will end with your characters sometimes gaining anywhere from 10 to 20 levels depending on how long the battle lasted and how many times King Cactaur used his attacks.
Get ten Door To Tomorrows, either by bribing the Mech Leaders with 74,000 gil (found in Mount Gagazet), or by stealing from Omega Weapon. A third way to is to catch many different kinds of monsters and then going to the Monster Arena. When you complete one area, the keeper will give you 99 Door To Tommorows. After you have them, customize a weapon with the Overdrive -> AP ability. Next, get the Loner Overdrive by having everyone but the person with the Drive -> AP weapon flee the battle. After a few turns, the character will learn the Overdrive mode Loner automatically. Next, equip the character with armor that can either block or absorb an elemental attack. Engage in a battle with an enemy that only uses that magic (for example, Flame Flan, Snow Flan, Gold Elemental, etc.). Have everyone else flee, and keep Triangle held with a rubber band. In a few hours, you will have 99 S. Levels from one battle.
You need to have control of the airship to do this trick and a weapon with Sensor would be helpful. Find the Omega Ruins with the search. Stay close to the Save Sphere where start at, and move around until you are attacked. If you are attacked by a Master Tonberry have Wakka equip his Capture weapon and use the skill Sleep Buster to put it to sleep. It will sleep for only one turn, so bring in Tidus and cast Hastaga. If you only do magic attacks and no physical attacks, it will use its turn to wake up and you just need to put it back to sleep. Keep casting magic (have Lulu use Demi if she has it) and Sleep Buster. Bring in the person with the Sensor weapon and when it gets down enough where you can kill it, use Wakka's Capture weapon to kill and capture it. You will get the 20,000 AP, but now since its caught you and easy to kill, you can go to the Calm Lands. Go to the Monster Arena and you can fight it again for only 3600, and still get 20,000 AP.
If your characters have the double AP (customize with 20 Megalixers) or triple AP (customize with 50 Wings to Discovery) then go to Bikanal Island (the desert) and complete the Cactuar mini-game so the sandstorm will disappear. Go to where the sandstorm was located and you will encounter either Sand Worms or Cactuars. Sometimes there will be three Cactuars in a battle so you can get 36m000 AP just for winning that fight. With your Double or Triple AP, you receive 72,000 or even 108,000 AP. Just have strong attackers with good agility and accuracy or they will run away or cast 10000 Needles, which can be quite deadly.
Unlike other Final Fantasy games, the AP earned during battles are not divided among the people in the party. Try to as many characters as you can involved to level up faster.
Immediately after you get the Aeon Bahamut, you will be in the Via Purifico (the place where you have to control Yuna because your party was split). Go north to a long hallway lit in red. Go into the hallway, fight a larva person and summon Bahamut. From there, use Thundaga or Firaga. You will get 1000 to 1200 AP. After each battle, go back to the save point to heal your Aeons and party. Repeat until you reach your desired level.
Use the following trick to get more levels and fill your total Sphere Grid within three or less hours. Certain items and weapons are required. First, you need to be able to fight One Eye on the monster arena (in the Calm Lands). Fight and kill One Eye until you get a triple AP weapon with two empty spaces for one of your characters. After you get the weapon, use the Customize Weapon option and add the abilities: Overdrive -> AP (which uses ten Door To Tomorrows), and also either Triple Overdrive (which uses Winning Formula) or Double Overdrive (which uses Underdog's Secret). Once done, change the character's Overdrive to Loner and get into a battle anywhere (preferably Besaid Island). When in the battle, make all other characters leave, and have your character choose the special weapon. After you equipped the weapon, have them skip their turns for at least twenty five turns. Try using Haste on your character and Slowga on the enemies. Then, kill all the enemies. The post-battle screen should state that your character either gained 200,000 AP (if Double Overdrive was used), or 300,000 AP (if Triple Overdrive was used). Within a few hours of gaining these levels quickly, you should be able to complete on the characters entire Sphere Grid.
Complete the Village Of The Cactuars side quest, then equip as many people as possible with weapons that have the Double AP, Triple AP option. Have everyone in your party use a skill. For example, Tidus with Cheer, Yuna with Pray, etc. Have Auron perform Zombie Break on the Cactuars. If it is successful, it does a 100% Overkill.
The best place to train, is at the Sea Of Sorrow. More AP can be gained here than anywhere else, and the enemies are not as difficult as in Omega Ruins.
Have a weapon that has Triple Overdrive, Triple AP, and Overdrive > AP. Set Overdrive to Stoic and fight Don Tonberry. Attack him with the weapon, then he will kill you. Revive that character then repeat the process until you kill him. You will get 30 to 80 Sphere levels.
To get easy AP early in the game, have Tidus learn Cheer. When you battle Sin for the first time on the boat to Kilika, instead of attacking Sin have Tidus use Cheer on himself, Wakka, and Kimahri. Then, repeatedly attack the blue that Sin sends at you. Make sure you use Lulu and Yuna at least once so they also get some AP. If you do this long enough, you can get at least 20 levels up per hour.
Defeating The Spherimorph
To prepare, start training vigorously from the time the game starts to the time you get to the Spherimorph (about ten fights minimum in each area). You should have about 15000 gil or more when you are ready. Go to O'aka and ask for weapons. Leave, then he will ask you about the prices. Tell him that they are too expensive, then go back and buy weapons. The prices should be lowered to some extent. Buy the Sonic Steel for Tidus, Rod of Darkness for Yuna, and the Force Knuckles for Rikku. When you get to the part of the Macalania Woods where you fight Spherimorph, immediately save if you are uncertain that you can defeat it. To fight Spherimorph you should equip the following recommended items. Tidus (Sonic Steel, any armor with Magic Def 3or 5%), Yuna (Rod of Darkness or Laevatein, Seeker's Ring; HP + 10%), Wakka (Switch Hitter, Emerald Armguard), Lulu (Fatal Cait Sith or Water Moomba, Seekers Bangle), Auron (Shimmering Blade, Recovery Bracer), Rikku (Force Knuckles, NulBlaze Target), Kimahri (Hunters Spear, Red Armlet). Start the fight with Tidus, Auron and Wakka. Tidus goes first, so set the tone with his Overdrive (if he has it). Do not use Wakka's Overdrive because it is elemental and will heal Spherimorph. Instead, use a physical attack. Use Auron's Magic Break to weaken spells, then switch in Kimahri and use his Jump or Seed Cannon Overdrives (if he has them). Use Yuna and summon Ifrit. Use his physical attacks to damage Spherimorph. Spherimorph will attack with Fire, thus healing Ifrit. Switch out Ifrit and use normal characters occasionally. Switch Ifrit back in and use his physical attacks until Spherimorph starts using its physical attacks frequently. Dismiss Ifrit and use Auron's Power Break to weaken its physical attacks. Then, finally pummel it down with either Ixion or Ifrit's physical attacks, occasionally healing them with elemental spells.
Have Tidus, Lulu, and Yuna on your team. Use Yuna to cast the Nul spells, then use Tidus' attack. Spherimorph will cast an elemental spell on Tidus. However, if you used the Nul spells it will not harm him. Have Lulu cast the opposite of that spell/ Spherimorph will then use Elemental Shift. Keep repeating this and Spherimorph will soon be dead and you will suffer no damage.

If you have a weapon with "Capture" equipped and manage to use it in the finishing hit, the Behemoth King will not do his "Meteor" counter-attack before dying.

Defeating The Stratoavis In The Battle Arena
Once you collect all the monsters from the desert, go back to the Calm Lands and go to the Battle Arena. If you have caught all of them, the man will offer you a free fight with the new monster he just created. Accept his offer. Once in the battle, make sure you have Yuna in your party. Wakka and Tidus are also recommended. To make this faster you will need the Aeon Yojimbo. He can dodge all the attacks from Strutoavis and put Yojimbo in Overdrive. This should enable you to pay a low price for maximum damage. You should be able to pay 10 to 20 gil and he will do one of four attacks. If he does Wakizashi or Kozuka, it should do maximum damage. Do this about fifteen to twenty times and he should fall. You should get about 10,000 AP for winning, and perhaps a Key Sphere.
