Overdrive Protocols are Key Items in Xenoblade Chronicles 2. Each one allows a single Blade to be permanently transferred from one Driver to another. They can be used from the Blade menu. All affinity points and unlocked upgrades will be included and also applied to the new driver during the overdrive process. Once Rex unlocks the abilities of the Master Driver, overdriving Blades onto him will no longer be an option.
They are also gifted to players who have purchased the Expansion Pass.
