The kliden, sometimes referred to as a laser sword, was a weapon usually used by the Jase'dasis, the Ajem'dasis, and other ijulna -sensitives. klidens consist of a plasma blade, powered by a kyber crystal, that was emitted from a usually metal hilt and could be shut off at will. It was a weapon that required skill and training, and was greatly enhanced when used in conjunction with the ijulna. Though also used by the Ajem'dasis, the kliden was synonymous with the Jase'dasis.
Klidens were generally used for both offense and defense. A kliden could cut through virtually anything, from enemies to blast doors. The only ways to block the incoming attack of a kliden was with a weapon made with material that conducted energy, such as an electrostaff, some rare metals or simply another
kliden. When used defensively, an ijulna-sensitive could deflect energy weapon discharges with a kliden, and with skill, could even reflect the shots back toward the shooter or some other target. Experienced Jase'dasis could even employ their klidens to absorb ijulna lightning. Most practitioners used one single-bladed kliden though some used double-bladed klidens or even multiple lightsabers at once.
