In-game reset
Press L1 + L2 + R1 + R2 + Start + Select during game play.
Hint: 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.
Hint: Easy Aeon healing
Instead of bothering to have one of your Aeons learn any of the cure spells, try this. For the elemental Aeons (Ifrit, Shiva, Ixion, etc.), try using a spell that corresponds with their element (Ifrit: Fire, Shiva: Blizzard, Ixion: Thunder). This heals them much more than if you did any cure spell You can also try the advanced spells (Fira, Blizzara, etc.).
Hint: Aeons and legendary weapons
Although it may seem as if your legendary weapons are weak and useless, get all of them and your Aeons will have a normal attack of 9999.
Hint: Quick healing and restoration
Every time you save the game at a save point, it will completely heal all the party members, revive all summons and completely heal MP.
Hint: Low MP spells
Equip items with the one MP ability and Magic Booster. This makes each spell cast cost one MP, and Magic Booster makes the damage x1.5 for double the MP. Then, double cast these spells for a cost of only 4 MP.
Hint: Defeating Biran
When fighting Biran and Yenke with Kimahri, use Lancet on each of them a few times. You should get a few Ronso Rages. Use Lancet again after Biran has used Mighty Guard to also obtain it.
Hint: Defeating Evrae Altana
Use two or three Phoenix Downs on it to kill it instantly.
Use an X-Potion for a one hit kill.
Hint: Defeating the Sanctuary Keeper
Have Yuna cast Reflect on the creature. Then have your highest hit point character hack away at it. It will still cast the Cure and Regen spells, but with Reflect it will be healing the party instead of itself.
Hint: Defeating Bosses
Get all your Aeons' Overdrives character's Overdrives up before battle. When you enter the battle, let everyone hit once with their Overdrive (so at the end they all get experience) and let Yuna summon her Aeons and use their Overdrives. Try using Yuna's Overdrive "Grand Summon" and summon your best Aeon. You can use two Overdrives with hem if you charged them up.
Hint: Defeating enemies that use Reflect
Have a party member cast Reflect on another party member. Then, just use an attack spell on that person. For example, when you are fighting an enemy with Reflect, to attack that creature with magic first use Reflect on Tidus with Yuna. On the next move, use Thundaga on Tidus. It will reflect to the enemy and will not be reflected back.
Hint: Omega Weapon and Ultima Weapon
To find Omega Weapon and Ultima Weapon you must explore the ruins with a No Encounter ability on one of your characters (Peaceful Bangle, Ductile Rod, etc.). The best way to find them is to have a high level. When you enter you will be tempted to go straight. Instead, go to the left and then straight. The rest of the way should be obvious.
Hint: Potions
At the very beginning of the game, as you head down the long road to get to the Blitzball stadium, talk to the girl running around who talks about tickets more than once. Eventually she will say that tickets are sold out, and will ask if you can get tickets for her. Tell her you can, and she will reward you with two Potions.
Near the start of the game, when you get on the S.S. Liki after getting Yuna, you should be able to explore the ship for a little bit. When you get to walk around, go downstairs. A man will talk to you about your clothes. After he is done talking, go to the only open room (on the left side) in the hallway. You should see a seasick man with his head out the window. On the far right of the screen, you should see a suitcase similar to the one Yuna was going to bring on the boat. Go up to it and press X to kick it. You will receive a Potion. Keep kicking it to get about fifteen free Potions.
When you meet Yukku on the salvaged ship, talk to the man with a gun that has a knife on it. Talk to Yukku and talk to the other person. You can only understand Yukku, but after you talk to them all you will get three Potions.
