The cortosis staff was a melee weapon produced by the Morgukai warriors—a sect of Kajain'sa'Nikto—for use in single combat against Jedi. The staff was laced with cortosis ore, a mineral naturally resistant to a lightsaber. The top of the staff can emit a small plasma blade just like that of a lightsaber. The bottom of the staff featured a small but powerful electrical generator which not only powered the energy blade but could release powerful bursts of electrical energy on contact with an object. This allowed the staff to be an electrostaff, a lightstaff and a lightspear all rolled in one.
