Overdrive Mode

Overdrive menu.

Overdrive Modes are a setting used to determine how the Overdrive gauge fills in Final Fantasy X. Each character must learn each mode separately by fulfilling its condition a certain number of times, which varies depending on the character. Once a mode is learned, the player can select it from the main menu. Only one mode can be set at a time for any given character.

It is not possible to learn Overdrive Modes in the Monster Arena.

The values below are extracted from Final Fantasy X Ultimania.
