Blade Resonance is a mechanic in Xenoblade Chronicles 2. Drivers can resonate with Core Crystals to awaken new Blades and increase their possibilities. It is not possible to anticipate what kind of Blades will be created from a Core Crystal. Weapons and arts granted to a Driver depend on the awaken and selected Blades. Drivers can bond with multiple Blades and use three of them during battle. It is possible to switch Blades in order to obtain more combinations allowing more playstyles.
