Welcome to our Lightsaber Crystal Guide, a handy (we think) table including statistics on every crystal in KotOR, and an easy to read format.

In the extended lore, Lowbacca is the only known wielder of a bronze lightsaber, Freedon Nadd was also known to wield a bronze-bladed short lightsaber, which players can find in Star Wars: Knights of the Old Republic II, though both of these sabers are drastically different colors.

In the PC version, two new incredibly powerful crystals were introduced: the Heart of the Guardian and Mantle of the Force

1. Bosnia and Herzegovina is a religiously diverse country. According to the census of 2013, Muslims comprised 50.7% of the population, while Orthodox Christians made 30.7%, Catholics 15.2%, 1.2% other and 1.1% atheist or agnostic, with the remainder not declaring or not answering the question.
2. Not 2 sure bout bronze and cyan think theyre random. To get silver talk to geeda and chase away oondar, then tell her taht ull find her a forieng trade thing complete onderon or dantooine main quests and bam go back to geeda and shell have a silver crystal silver can be gotten random too.

. They are inserted into the hilt of the saber, and greatly enhance each of the crystals placed in the remaining two slots. This table shows the effects of every crystal when combined with either the Heart or Mantle hilt crystal. As a bonus, the sabers glow a unique color when these crystals are inserted. Using this table, it's possible to figure out with a minimum of effort which combinations of crystals work best for your style of play.
To find the location of any of these crystals, refer to our equipment section under upgrades.

Upari	AB: 3, DB: Energy, 1d8	AB: 4, DB: Energy, 2d6	AB: 2, DB: Energy, 1d6 BBD: +8

The Most Powerful Combinations:

Light Side Players: Solari + Upari
With a normal 2-16 saber, and not using the Heart of the Guardian or Mantle of the Force, the damage becomes 6-27 Energy, +1d8 Physical vs. Dark Side, with the almost unequaled +6 to attack.
With a normal 2-16 saber, and with the Heart of the Guardian, the damage becomes 5-38 Energy, +6 to Attack, and +4 Blaster Bolt Deflection.
With a normal 2-16 saber, and with the Mantle of the Force, the damage becomes 6-42 Energy vs. Dark Side, and 4-30 Energy vs. everything else, with +6 to attack, and an incredible +8 to Blaster Bolt Deflection.

Non-Light Side Players: Upari with your choice.

Blaster Deflection: With two sabers, this can become amazing: Heart of the Guardian + Jenruax + Solari = +11 BBD. Mantle of the Force + Jenruax + Upari = +13 BBD, for a virtually impenetrable blaster barrier of +24.

Vs. Droids: Firkrann + Luxum adds 3-18 Ion Damage with +4 to attack to a normal saber. With either Heart of the Guardian or Mantle of the Force, this combo adds an astounding 5-30 Ion Damage on top of the energy damage, with +6 to attack.

Manic Force Regeneration: Mantle of the Force + Damind or Rubat + your choice = an almost inexhaustible force point well at +2 or +3 to regeneration. Believe me, it counts. (If you're not using patch 1.03, the regeneration is bugged. Otherwise, have fun!)

Personal Favorite Using 2 Sabers:
1st Saber: Mantle of the Force + Solari + Damind on a 2-16 saber = 6-37 Energy vs. Dark Side, 4-25 vs. everything else, +5 to Attack, and the amazing +2 Force Point Regeneration (which I now believe is bugged to have sadly no effect, and otherwise would be very noticeable). You may also add the Rubat instead depending on what class you play. Guardians may wish to add the Rubat for +3 Regen, but Consulars, with their already high force point total, might be better off opting for the added attack and energy of the Damind.
2nd Short Saber: Heart of the Guardian + Krayt Dragon Pearl + Upari with 2-12 base damage = 5-32 Energy Damage, with the heat-seeking +7 to attack.

My Post on the BioWare Forums before patch 1.03:
Subject: Bugged Damind & Rubat Crystals when combined with Mantle of the Force

Kotor 2 Best Crystals

The Damind & Rubat Crystals are supposed to add +2 and +3 to Force Point Regeneration respectively, when combined with the Mantle of the Force.
I tested this out with my 22 Wisdom Consular, with 227 Force Points at Level 19, both inside and outside the Ebon Hawk.
With each test, I used Force Immunity until I was at 1 Force Point, and then brought up the character sheet to double check. Using the second counter on a digital clock, I clicked the dialog box 'closed' when the seconds reached 00.
Results:
With no lightsabers equipped on my character, and neither the Rubat, Damind, or Mantle of the Force inserted into any lightsabers on any character:
Time from 1 - 227 Force Points: 1:40 minutes.
With the Damind Crystal inserted into one lightsaber, along with the Mantle of the Force, and equipped. The stats correctly showed the +1 to Attack, +1 to Damage, and +2 to Force Regen.
Time from 1 - 227 Force Points: 1:40 minutes.
With the Rubat Crystal inserted into one lightsaber, along with the Mantle of the Force, and equipped. The stats correctly showed the +3 to Force Regen.
Time from 1 - 227 Force Points: 1:40 minutes.
With both the Damind & Rubat inserted into one lightsaber, along with the Mantle of the Force, and equipped. The stats showed +1 to Attack, +1 to Damage, +3 to Force Regen.
Time from 1 - 227 Force Points: 1:40 minutes.
My conclusion: sadly, they're bugged.
