Final Fantasy X is a popular role-playing game released by Squaresoft for the PlayStation 2. In the game, players control an eclectic party of characters as they attempt, with the help of the hero Titus, to save the planet of Spira from a moribund fate. Players repeatedly face the enemy Seymour, who appears in increasingly devastating forms, including the Seymour Flux form on Mount Gagazet.
Load Final Fantasy X and start a campaign.
Reach the Mount Gagazet stage of the game, which is approximately 2/3 of the way into Final Fantasy X.
Prepare the right team for the fight. Although other combinations may work, the best team to fight against Seymour Flux is composed of Tidus, Yuna, Lulu and Auron.
Equip your team with the right set of abilities. Make sure Titus knows Hastega, which will increase your characters' speed during the fight. Make sure Lulu knows Bio and her "daga" level spells, and teach Yuna Dispel, Project and Shell. Placing a Zombie protect on your characters will also be helpful.
Get your team and your summons into Overdrive by fighting a few battles against random enemies. By doing so, you'll be able to use their Overdrive attacks as soon as the battle starts.
Save your game and enter the battle. Prepare to take several attempts at defeating Seymour; even the best-prepared team will sometimes lose to him. Seymour has 70,000 HP and 512 MP at this stage.
Cast Hastega on all of your characters, and use Auron's Shooting Star Overdrive attack. Use Lulu's Bio attack on Seymour, which will deal damage to him on each turn of battle. Have Yuna cast one of her Overdrive summon attacks each turn. As long as your team is healthy, have Auron use normal physical attacks on Seymour; when one of your character's HP gets low, use Seymour for healing.
Cast protective spells like Shell on your party for damage limitation. Make sure to have Shell cast as Seymour prepares his devastating Mortiorchis attack, which will kill your entire party if you don't have it in place.
Cast the Shiva Grand Summon near the end of the battle, which will always deal Seymour 9,999 damage, the maximum for any attack.
Continue attacking Seymour until he dies. As this is one of the hardest battles in the game, defeating him may require multiple attempts.
