Eternal Legend - Final Fantasy X
Final Fantasy X Overdrives

Following in the tradition of desperation attacks and limit breaks, Final Fantasy X introduces Overdrives. Although in the beginning Overdrives may only be charged by the character receiving damage, more ways of charging the meter are soon learned by performing various actions in battle. For example, the Warrior mode, which charges every time the character damages an enemy, is learned by repeatedly attacking enemies.

When the Overdrive gauge is fully charged, the character may then use powerful unique abilities. If not used in the same battle in which it became full, the gauge will remain full until the battle in which it is used.
