Energy blade

Energy blade was a Ta-Ree spell capable of being wielded by Ascendants on the planet Kathol. The spell was only known by Yapi shamans, and they rarely shared the technique with outsiders unless they demonstrated a great feat of bravery, or promised a gain of some kind.

The spell was applied to a melee weapon to increase the damage it could inflict. The weapon glowed brightly and acted much like a lightsaber. The affected weapon could parry lightsabers, and when used in conjunction with battle mastery, could be used to parry blaster bolts.
