Super easy way to get all six colors out of one kyber crystal for your lightsaber from Savi’s Workshop in Galaxy’s Edge (Disneyland and Hollywood Studios at Disney World). This also gets you all different character audio samples for your holocron. These are found in Galaxy’s Edge at both Disneyland and Hollywood Studios Disney World at Dok Ondar’s shop.
