Overdrive in action during battle

Overdrives are battle mechanics in Xenoblade Chronicles X. They are also known as OC Gears or Over Clocking Gears in the Japanese version. They are powerful tools for the party, allowing characters to greatly increase their fighting ability. Overdrive battle mechanics are comparable to Chain Attacks in Xenoblade Chronicles, although there is no time break involved, nor blue lines connecting the party members shown on the screen. During Skell battles, Overdrive can also be activated.

Activating an Overdrive consumes 3000 TP, similar to the reanimation of an ally. The gauge is filled by multiplying the attacks in a limited time, both to reduce the cooldown of the arts, but also to trigger Tertiary Cooldown, greatly augmenting effects from Arts that increase damage at higher cooldowns. They increase the arts' power by 400%, being more efficient than the Secondary Cooldown which increase arts' power by 250%.

Some Soul Voice types are allocated to Overdrives, in white, and can be attributed to allies.

When an Overdrive is activated, the track "Wir fliegen" plays until Overdrive is finished.

Overdrive usage


An example of a full Tension gauge with 3000 TP

Once Chapter 5 of the main story is completed, the party will learn the Overdrive. This powerful technique can greatly improve the combat capabilities during a short period by spending 3000 TP.

When enabled, the art cooldown time (required between each use) is significantly reduced, making possible to use them one after the other. In addition, it is possible to charge for a third time to activate the powerful Tertiary Cooldown, which is specific to the Overdrive. As the accumulated TP can be carried over to the next battle, if the party has trouble against a Boss or a Tyrant , it is a good alternative to accumulate beforehand these 3000 TP.

  • Overdrive Counter: The colour changes depending on the arts used.
  • Overdrive Time: The gauge, to the right of the counter, is reduced little by little, and the Overdrive will end when it comes to zero. It can be extended with combinations or by accumulating 3000 TP while in overdrive and initiating it again from the overdrive counter.

Overdrive mechanics during battle




  • Count Effect: By using same type arts one after the other, for example two Ranged Arts (yellow twice) or two Melee Arts (orange twice), each hit increases the counter by 1. Some particular effects can be obtained such as "Overdrive Time Extension", "Extra Damage", and "TP Gained During Attack" depending on the counter number.
  • Color Combo: By changing the Overdrive Counter color in a certain order (for example from yellow (ranged) to green (support)), some particular effects can be obtained such as "Double Count", "Appendage Damage Increase", "HP Recover" and "Experience Bonus".
    • Color bonuses: These occur when an art of a certain color is used regardless of the color of the counter
      • Green: Overdrive extended by .05 s x counter value
      • Blue: Overdrive extended by .1 s x counter value
      • Purple: Gain 10 tp x counter value per hit
    • Color combinations: These occur when the counter is a certain color and an art of a specific color is used. The effect is applied to the art used.
      • Yellow to orange and orange to yellow: Overdrive counter does not increase
      • Green to orange, yellow, or purple: Overdrive counter increases by 2x the number of hits
      • Purple to orange or yellow: extra appendage damage
      • Blue to Green: HP recovered
      • Blue to Purple: Effect duration increased
      • Orange to orange to orange: +10% EXP, up to a max of +200%
      • Yellow to yellow to yellow: +10% class EXP, presumably also maxed at +200%
  • Party Chain: If the allies accumulate 3000 TP while the playable character's Overdrive is activated, their own Overdrives can also be activated. By simultaneously using multiple characters' Overdrive, some special effects can be obtained. These effects are:
    • 2 party members in Overdrive: +50% of Soul Voices' activation rate.
    • 3 party members in Overdrive: Gain 50 TP when using arts per hit.
    • 4 party members in Overdrive: The whole party gets a special buff called "Super armor" which cuts all damage in half and grants immunity to mobility debuffs such as Stagger, Topple, Knockback, Launch, and Flinch.
  • Restart: By reaching 3000 TP while using Overdrive, it is possible to restart it in order to extend the Overdrive Time.
  • Cooldown: Cooldown during overdrive = Cooldown / (2.5 + 0.025*counter value) = Cooldown / 5.0 at MAX counter value.

Overdrive and Skell battle

The Skell Battle

Overdrive can also be used during Skell battles. Similar to normal battle, Overdrive can be activated by consuming 3000 GP. During an Overdrive activation, Skell Fuel is not consumed. Cockpit Time is triggered more often while in Overdrive. Skell Overdrive grants various effects depending on the Skell frame, such as hit point regeneration, attack reflection, self-damage, or boosted stats.
