Baldur’s Gate 3 (BG3): Best Barbarian/Fighter multiclass Karlach build

Honestly, I think the Berserker Barbarian is great on its own. But the best Karlach build is another step up if you multiclass her as a Berserker Barbarian and Battle Master Fighter. Both classes rely on Strength and they both have unique abilities that make Karlach stronger and more versatile. Here’s how you can craft the best Karlach multiclass build in Baldur’s Gate 3.

Best Karlach Ability Scores in BG3

Since Karlach’s classes both require high Strength, prioritize that Ability when respeccing her Ability Scores. After Strength comes Constitution, since you want her to be as tanky as possible. Dexterity is pretty important, too, since this helps raise her AC. You can ignore Intelligence, Wisdom, and Charisma since this Karlach build is focused on dealing and taking high damage.

Best playstyle for the Barbarian/Fighter multiclass Karlach build in BG3

With this build, Karlach can still have three feats, amazing combat maneuvers, and plenty of attacks to hit during one turn. The Savage Attacker feat is amazing for dealing the most damage, and Tough helps Karlach stay alive on the battlefield.

At level five Barbarian, you get Extra Attack and at level two Fighter, you get Action Surge. This allows you to deal three melee hits in one turn, and Savage Attacker makes those hits deal more damage. At level three Fighter, the build gets more exciting and versatile with the Superiority Dice and Maneuvers. Instead of Karlach being a big punching monster, she’s a big punching monster that has tricks up her sleeve.

Since she’ll be targeted most, I want Karlach healthy, but also a brutal attacker. When choosing Combat Maneuvers, you can go for any of them. I just chose those three, which I highly recommend you try out.

Make sure to always keep her rage up, and expend the Superiority Die or Frenzied Strikes on the toughest enemies. It’s also important to use Goading Attack to get the enemies’ eyes on her instead of her more squishy companions.

Who is Karlach in BG3?

Karlach is one of my favorite companions in Baldur’s Gate 3. You have a chance to recruit Karlach in Act 1. She gives you a choice to help her defeat the corrupt paladins that are hunting her or stay out of her way. You want to join Karlach, not only because she’s an incredibly powerful companion that has an interesting backstory and an engine for a heart, but also because her romance is one of the best.

Karlach works best with a two-handed weapon, so I gave her the Great Weapon Fighting Style. Just make sure to keep Karlach unarmored, since she can only rage without armor. Luckily, you can find clothes through Baldur’s Gate 3 with amazing abilities for Karlach to compensate for low AC. Make sure you find and use the best weapons for Karlach throughout BG3.
