Star Wars: Knights of the Old Republic/Lightsabers

Lightsabers require the Weapon Proficiency: Lightsaber feat. They can all be upgraded.

Short Lightsaber

 * Damage: Energy, 2-12
 * Critical Threat: 19-20,x2
 * Balanced: +2/+0 vs. two-weapon penalty if used in the off hand

Lightsabers can come in shorter styles, often used in the off hand during two-weapon fighting. As in larger versions, different focusing crystals can produce additional effects.

Lightsaber

 * Damage: Energy, 2-16
 * Critical Threat: 19-20,x2

Traditionally associated with the Jedi, the lightsaber is a devastating weapon difficult to master. Properties can vary with the type of focusing crystal used in construction.

KotOR Item Lightsaber, Red.png Sith Lightsaber

 * Damage: Energy, 2-16
 * Critical Threat: 19-20,x2

This lightsaber is quite intricate in its design, the hilt covered in delicate runes and inlaid with black markings. No doubt the purpose of the weapon is primarily ceremonial, though it certainly seems to perform as a lightsaber should.

Double-Bladed Lightsaber

 * Damage: Energy, 2-20
 * Critical Threat: 20-20,x2

These exotic weapons are rare, and most often associated with Jedi attracted to the dark side of the Force, for whom reckless aggression is sometimes considered an asset. The double-bladed lightsaber is capable of inflicting more damage – but is also less precise – than the single-bladed variant.
