Tachyon Chips are Core Chips in Xenoblade Chronicles 2. They have a 9% chance of dropping from Tyrannotitan Kurodil and can only be acquired this way, and will be dropped with 100% chance the first time Kurodil is defeated.

Tachyon Chips uniquely revert a Rare Blade's weapon to its original appearance, whereas for Common and Legendary Blades it shares appearance with Dilaton Chips and Preon Chips.

Trivia

  • Rare Blade weapons equipped with a Tachyon Chip use the Blade's original weapon skin, rather than the standard global appearance for Tachyon, Dilaton, and Preon. Special Legendary Blades with weapons that can change appearance follow this same global theme, with the exception of Aegaeon whose weapon returns to its original appearance.
