In the video game, Star Wars: Knights of the Old Republic you may use this crystal as a lightsaber upgrade. It has a 25% chance to stun your opponent on hit for one round. The Star Wars D20 KotOR Campaing Guide states instead: "Bondar crystals convert the energy of a lightsaber blade into a different form of energy. A lightsaber constructed with a bondar crystal deals stun damage instead of normal damage. Training lightsabers are made with bondar crystals."
