The lightsaber is a unique indestructible phase blade sword. Its most prominent feature is that it is an incredibly fast weapon, even without any IAS bonuses from other equipment. It has a variety of mods that make it a versatile weapon.

For a one-handed unique sword, the lightsaber does a decent amount of damage. Also deals magic and lightning damage. While there are some creatures that are immune to lightning damage, there is only one creature in the entire game that is immune to magic damage. Coupled with its incredibly fast speed, the Lightsabre, much like its sister sword Azurewrath, makes it a very viable weapon option.

5-7% mana stolen per hit (varies)

Good for melee characters who use mana-consuming abilities.

5% chance to cast level 14-20 Chain Lightning on attack (varies)

Chain Lightning is a lightning spell in the Sorceress’s Lightning Spells skill tree. Fires a bolt of lightning that passes through Enchantress’ enemies, jumping from target to target until it dissipates.

A level 20 chain lightning spell can deal 1 to 281 lightning damage and strike up to nine targets.

With such a fast weapon speed, the Lightsaber will trigger Chain Lightning a few more times than the modest 5% in the mod would indicate.

20% increased Attack Speed

The lightsaber is already a fast weapon, but this 20% IAS is the icing on the cake. Equip a few more items on your character that grant IAS, and you’ll see that Lightsabre breaks the maximum breakpoint of IAS with no problem.

Ignore target’s defense

Ignoring the target’s defense doesn’t mean you can now successfully hit targets with each of your attempts, but it sure does make it much easier to successfully hit your enemies.

This ability does not work on champions, uniques, bosses, or players.

Absorb Lightning 25%

The lightsaber provides incredible lightning absorption. If you have maximum or near maximum Lightning Resistance, and also have Absorb Lightning, you will not only ignore most of the lightning damage you take, but also heal a small amount of health.

+7 to light radius

This is a very big boost to your light radius, but it’s almost useless for melee characters or casters, and at best marginally useful for bow using amazons.

Summary:

The lightsaber might not be the most damage-dealing weapon in the game (those tend to belong in the weapon runewords), but it’s a very viable late-game option. Barbarians who make use of the Frenzy ability find the lightsaber a good makeshift weapon due to its naturally fast speed.
