Overdrives

Overdrives are, in a sense, the Limit Breaks of Final Fantasy X. Each playable character has an Overdrive gauge which is charged during battle, depending on the currently selected Overdrive Mode. For example, if the Stoic mode is selected, the character's gauge will increase each time they take damage from an enemy attack, and if the Healer mode is selected, the gauge will increase each time the character restores HP to an ally. When it is full, the player can select an Overdrive to perform. The Overdrive gauge is maintained between battles, so it is possible to charge one's Overdrives before a boss battle.

Each character has a unique Overdrive.

Tidus: Swordplay

Tidus performs a technique with his sword to cause damage to one or all enemies. There are four Swordplay techniques-- Spiral Cut (available initially), Slice and Dice (available after performing 10 Overdrives), Energy Rain (available after performing 30 Overdrives), and Blitz Ace (available after performing 80 Overdrives).

Yuna: Grand Summon

Yuna summons an aeon with its Overdrive fully charged. After the Overdrive is used, the aeon's gauge reverts to its previous state-- that is, to the amount it was at before Grand Summon, making it possible for an aeon to perform two Overdrives in a row.

Wakka: Slots

Slots are displayed which the player can manually stop. Depending upon the results and the type of slots used, the results can differ. There are four types of Slots: Element Reels, Status Reels, Attack Reels, and Aurochs Reels. The latter three must be won in blitzball games.

Lulu: Fury

Lulu's Fury uses any Black Magic spell that she's learned. The player must rotate the left analog stick as quickly as possible for a set amount of time, and the number of revolutions completed determines how many times the spell will hit.

Kimahri: Ronso Rage

Ronso Rage uses enemy techniques learned by having Kimahri use Lancet on certain enemies to learn their skills. Each time Kimahri learns a new Ronso Rage, his Overdrive gauge fills automatically.

Auron: Bushido

Bushido skills are sword attacks which often inflict status ailments. There are four Bushido abilities in all, and the last three are unlocked by obtaining Jecht Spheres-- Dragon Fang (available initially, inflicts Delay), Shooting Star (available after obtaining one Jecht Sphere, inflicts Eject), Banishing Blade (available after obtaining five Jecht Spheres, inflicts all four Breaks), and Tornado (available after obtaining all ten Jecht Spheres, does not inflict any status ailment but hits twice). If the enemy is immune to the status ailment, the damage will be slightly increased.

Rikku: Mix

Mix allows Rikku to combine any two items in the inventory to cause various effects, such as doing damage to the enemy or healing or supporting the party.
