Special Features:
The weapon features a crossguard, which helps to protect the wielder's hands from harm during battle, though the wielder must also be careful not to injure themselves.
Though it has no effect on performance, the weapon utilizes a krayt dragon pearl as a power source, giving it a violet blade.
Description: As Nyx progresses on her journey into the Dark Side, she decided it was time for another lightsaber, to celebrate her newfound power. Unlike her first lightsaber, which was as average as they come, her second features a crossguard.
While this provides protection and extra offence in combat, this advantage is countered by the danger these extra blades pose to the wielder. In combat, the wielder must be careful not to injure themselves with the extra blades, meaning several mainstream lightsaber combat forms and moves cannot be used by the wielder without the use of concentration the likes of which Nyx simply does not have.
The weapon also features a krayt dragon pearl as a power source, and though it has no effect on the performance of the lightsaber, this power source means the weapon is extremely difficult to modify.
