Photon Sabers are melee weapons in Xenoblade Chronicles X. They are depicted as swords that project beams of damaging light from the hilt, and the blades may sometimes expand and change form during the use of certain arts. They are used by Blast Fencer and Galactic Knight classes. When Galactic Knight is fully mastered, Photon Sabers become usable with any class. They are wielded by Yelv and Doug, and a similar weapon is wielded by Ga Jiarg.
