This is a guide for my favorite build in SW:KOTOR1 and also the strongest beast that i managed to make which is a Light Side, Strength and Wisdom focused Scoundrel 7 / Consular 13 aiming for high survivability while maximizing DPS. English isn't my primary language so don't be surprised if you see mistakes. I did try my best to be as clear as possible.
If you only wish to know the final product of the build without the extra explanations, go to Character Summary. This is a detailed build guide with additionnal alternatives that might fit your playstyle better. It isn't an ideal build for a first playthrough so i would advice that you complete the game first, especially that this guide contains spoilers.
Has the potential to solo the RCM Impossible difficulty, Taris still won't be a cakewalk but it is definitely doable for an experimented player;
Able to do all skill checks in the game with minimal gear switch using the right party members;
Insane effective DPS, able to one shot Darth Malak with 95% accuracy per hit (max) and debilitate him consistently as you can see on my video here (older version of the build, was my initial test);
Great survivability with high defense, good damage resistance and immobilizing powers;
Minimal level saving for an optimal build so even Taris is not a problem at all and very smooth;
Can effectively use the power of sneak attacks (4-24) for additionnal damage but will perform totally fine without any immobilizing powers too if needed.
While pretty restrictive on feat and powers compared to other builds, remains quite customizable.
Stat enhancing temporary buffs: Master Speed, Master Valor, Hyper Adrenal for Strength, Dexterity and Constitution, Echani Battle Stimulant.
Possibility to sacrifice strength for dexterity for additionnal defense using those items instead:
Advanced Alacrity Implant (+5 dexterity)
Baragwin Stealth Unit (+3 dex)
Off hand short lightsaber with Mantle of Force and Crystal Jenruax (+1 dex)
For a total dexterity of 34 and 41 defense instead of 36 at the cost of 2 strength, 2 saves, 1 attack, 2 damage and a Baragwin assault blade off hand damage. The reason why i don't recommend that setup however is that the build focuses on damage reduction and immobilization using force powers so more defense is useless. This dexterity setup has the highest total attribute so it might still interest some of you min-maxers.
Special thanks to Onderduiker for his amazing work on the Strategy Wiki making the writing and planning of such a build not only possible but a ton of time easier. If you have any questions about gear and mechanics, this wiki will most likely answer them. Also special thanks to TangoSierraFan for his optimal Guardian/Consular guide, who inspired me to use a google site format for builds. You can access his work here. Give it a read, it's totally worth it. And finally to the whole KOTOR community for being positive and keeping this game alive after 20 years, this guide is for you.
