Baldur’s Gate 3 Karlach Build: Max Damage Strategy

When you first get Karlach, her stats are okay, but we can do better. A quick chat with Withers (for a small fee) lets you respec her into a truly optimized powerhouse.

Here’s the ideal ability score spread for her best build:

• Strength: 16
• Dexterity: 14
• Constitution: 16
• Intelligence: 8
• Wisdom: 12
• Charisma: 8

As a Barbarian, Karlach’s world revolves around Strength and Constitution. Strength pumps up her damage and chance to hit, while Constitution beefs up her health pool, making her incredibly tough to take down. We also want a respectable Dexterity score of 14, not just for the bonus to her Armor Class, but also to boost her Initiative, letting our favorite Barbarian act sooner in combat. Wisdom at 12 helps with crucial saving throws, and we can safely dump Intelligence and Charisma because, let’s face it, Karlach solves problems with her axe, not with philosophical debates.

The Best Level-by-Level Build for Karlach

If you’re ready to transform her from a strong companion into an unstoppable force of nature, follow this level-up guide. We’re going to multiclass at the end to squeeze out every last drop of damage potential, making this Karlach build truly legendary.

• Level 1: Barbarian – Unlocks Rage and Unarmored Defence.
• Level 2: Barbarian – Gets Reckless Attack and Danger Sense.
• Level 3: Barbarian – Subclass: Berserker. This is where Karlach gets fun with Frenzy.
• Level 4: Barbarian – Feat: Ability Improvement (Strength +2). We boost Strength to 18 for more consistent damage.
• Level 5: Barbarian – Extra Attack and Fast Movement. This is a massive power spike for her.
• Level 6: Barbarian – Mindless Rage. Karlach becomes immune to Charm and Frighten while Frenzied.
• Level 7: Barbarian – Feral Instinct. She gets a +3 to Initiative and can’t be Surprised.
• Level 8: Barbarian – Feat: Great Weapon Master. This is the game-changer, adding a huge +10 damage to her attacks.
• Level 9: Barbarian – Brutal Critical. Karlach hits even harder on critical hits.
• Level 10: Barbarian – Intimidating Presence. A situational crowd control ability.
• Level 11: Fighter – Great Weapon Fighting Style. We start our multiclass dip for a damage boost.
• Level 12: Fighter – Action Surge. The glorious capstone, giving her an entire extra action once per short rest.

This build ensures that by the endgame, your Karlach is an absolute monster. The combination of Extra Attack, Frenzy, Great Weapon Master, and Action Surge means she can unleash a truly staggering number of high,damage attacks in a single turn, melting bosses and clearing battlefields with terrifying efficiency. This is the ultimate Karlach, and she’s ready for a fight.
