Star Wars Knights of the Old Republic 2 comes with a new way to upgrade your lightsaber.

While the original Kotor only had two upgrade slots, Kotor 2 has five upgrade slots. Kotor 2 includes the same two crystal slots as the original but now comes with the option to add a cell, an emitter, and a lens.

These additional slots give you a lot more options when it comes to customizing your lightsaber for battle.

We’ve compiled a list of every crystal and addon for lightsabers and included some of the best lightsaber builds in Kotor 2 for you to use.

Kotor 2 Best Lightsaber Combinations

With 5 slots and a ton of different options, there are an insane amount of combinations you can make in Kotor 2.

Here are the best lightsabers for various situations you may face. Note that your personal lightsaber crystal may be better than one of either crystal offered in these builds.

Make sure you compare the stats of your personal crystal to the ones listed below and pick the one that’s best for your situation.

Best for Overall Damage

Barab Ore Ingot

Upari

Ultimate Diatium Energy Cell

Expert Fencing Emitter

Ponite Lens

This combo gives your lightsaber a bunch of different bonuses to hit your foes hard. After installing all of these in your lightsaber of choice, you will have +2-12 Fire Damage, +11-28 Energy Damage, +4 Attack Bonus, +2 Defense!

That’s a possible +40 bonus damage if you’re lucky not including any crit damage or your base damage.

Best Lightsaber For Droid Damage

Firkrann

Barab Ore Ingot

Superior Ion Energy Cell

Expert Fencing Emitter

Pontite Lens

If you’re facing a ton of droids, this should be the loadout you roll up with. You’ll melt through droids with your added +5-26 Ion Damage, +3 Attack Bonus, +2-12 Fire Damage, +1-6 Bonus Crit Damage, +2 Defense, and +5-15 Energy Damage.

Best Lightsaber For Blaster Bolt Deflection

Jenruax

Lorrdian

Any Cell. None have Blaster Bolt Deflection or any sort of defense buff. We suggest Telgorn III or Ultimate Diatium.

Expert Deflection Emitter

Ossus Dueling Lens

Sometimes its fun to just knock blaster shots back at your enemies. With these mods, your lightsaber will have a whopping total of +15 bonus Blaster Bolt Deflection, +4 Attack Bonus, and +2 Energy Damage, and +3 Defense.

This does not include the bonuses the cell you pick will have.

Best Lightsaber For Critical Hits/Chance

Opila

Ultima-Pearl

Superior Discharge Energy Cell

No Emitter has any increased crit chance or damage. We suggest using the Expert Fencing Emitter as it has some added energy damage (+3).

Beam Gem Lens

The above add-ons make your lightsaber a crit monster. Keen does not stack so it’s important to only take one Keen add-on.

With these installed in your lightsaber, you’ll get +7(+10 with the Fencing Emitter) Energy Damage, +4-26 Bonus Crit Damage, +4 Attack Bonus, and Keen.

And those are the best lightsabers in Kotor 2! We hope you enjoyed our guide and theorycraft some of your own builds!
