Sure, Lae’zel is a powerful fighter, but Karlach can dominate most fights even on her own. I’ll outline the best Karlach build in Baldur’s Gate 3.

If you’re about to dive into a tough boss battle, you must bring Karlach. But there are three unique Barbarian subclasses to choose from, and there’s always multiclassing. Here’s what to choose.

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 Karlach can utilize to her advantage. Here’s how you can craft the best Karlach multiclass build in Baldur’s Gate 3.

Best Karlach Ability Scores

Since Karlach’s classes both require high Strength, prioritize that Ability when respecing 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.

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.

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

She 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.
