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!
