Baldur’s Gate 3: BEST Karlach Build [Detailed Progression]

When it comes to centering your play styles around particular companions, the best BG3 Karlach Build is an easy and obvious recommendation. Karlach Demonsbane is a Tiefling Barbarian with several melee-based combative options. So, to create an ideal build with her, you must focus purely on those aspects to make her a close-range powerhouse.

Here’s a quick breakdown of Karlach the Barbarian’s build, detailing her optimal Class, Subclass, Feats, and best Potions in BG3:

Best Build And Level Progression For Karlach

Once you recruit Karlach Demonsbane into your party, you can use her as a melee attacker or a defender with her “Shield” ability. However, given her damage figures, background, and attacking tendencies, she’s more suited to an aggressive playstyle.

Before starting, it’s worth mentioning Karlach’s subrace, Zariel Tiefling, which you cannot change at any point in Baldur’s Gate 3. This subrace starts with excellent initial fire resistance and several combative attacks, naturally making Karlach a brute-like companion.

To get a clearer view of Karlach’s options, you can find her base stats from the list below:

Level 1/2: Barbarian Class

Karlach starts as a Barbarian class, and while you could change her class after a respec, it’s better to keep her as is. As highlighted by her race and subrace, she’s more suited to be around several enemies with close-range engagements, precisely where the Barbarian shines.

1. As a Barbarian, Karlach wouldn’t have to focus on wearing armor since her Unarmored Defense already gives damage resistance, which increases when you apply feats to raise her stats like Constitution or Dexterity.
2. Karlach begins with 17 Armor Class, making her reasonably resistant to attack rolls, but it’s better to wear medium armor if you raise Dexterity or Strength.
3. You also unlock her Rage ability, a temporary buff that adds +2 damage with throws and melee attacks while also providing defense against physical damage.
4. After reaching Level 2, Karlach unlocks some new abilities as part of her Barbarian Class, including:
   • Danger Sense: A Class Feature where you have an Advantage on Dexterity Saving Throws.
   • Reckless Attack: Until your next turn, you have an Advantage on Attack Rolls, but enemies also have an Advantage against you.

 

 

 

 

 

Level 3: Berserker Subclass 

At Level 3, you must also choose Karlach’s subclass, where you have three choices for Barbarian- Wildheart, Berserker, and Wild Magic. Each subclass has its pros, cons, and uniqueness, but I would suggest going for Berserker as it is the most simple one to use and is favored in most scenarios.

1. Unlike Wildheart or Wild Magic, which focus on utility, this subclass is meant only for close-range battles with lethal physical damage and aggression.
2. As a Berserker, you unlock the following abilities:
   • Frenzy: Your Rage turns into Frenzy as you gain Frenzied Strike and Enraged Throw, and you can also make an Improvised Weapon Attack as a bonus action.
   • Frenzied Strike (Bonus Action): Make a melee attack with your equipped weapon.
   • Enraged Throw: Pick up an item or creature and throw it at a target, dealing additional damage and knocking it Prone.
3. This subclass and attack sets encourage you to gather mobs to deal heaps of collateral damage, making it suitable for crowd control, especially before you hit Level 5 and get the Haste ability.

Important: If you’re looking for more out-of-combat utility, I suggest going for the Wildheart subrace as it gives you the “Speak With Animals” ability, unlocking narratives and relationships.

Level 4: Tavern Brawler Feat

This is perhaps the most divisive part of any build, especially Karlach, since there are several strong starting Feats in BG3, each with unique passive or active benefits. Most players here tend to pick the Great Weapons Master as it gives the most damage, but it also reduces accuracy. I suggest going for a safer and better option, Tavern Brawler.

Show Full Text

1. With this Feat, you can use an improvised weapon or throw something after an unarmed attack to add your Strength Modifier twice to your damage and Attack Rolls.
2. This added grapple bonus attack costs no resources, is unblockable, deals massive damage, and can be a safe move since you can equip and use a shield during the attack.
3. Furthermore, when picking Tavern Brawler, you’ll also get an extra skill point, which you should put in Strength to add to the Feat’s bonus and bump up your damage output.

Level 5/6/7: Additional Class Features

Beyond Level 4, the following few progression stages will solely add Class and Subclass features to your karlach build, letting you showcase your choices in the best scenarios. These abilities unlock several mobility and offense options that you can combine into a complete attack string.

Show Full Text

1. At Level 5, you gain Extra Attack for a bonus attack and Fast Movement.
2. It increases your speed by 3m without any Heavy Armor equipped.
3. Note that Extra Attacks and bonus attacks from other sources are separate, allowing up to 4 attacks in one turn.
4. At Level 6, you get Additional Rage and Mindless Rage, enhancing resistance and accuracy during Rage.
5. It also counters effects that reduce damage or cause missed attacks.
6. Additionally, Calm Emotions can’t end your Rage.
7. Level 7 brings Feral Instinct, providing +3 Initiative and immunity to surprise.
8. This ensures you won’t lose your first turn, and the added Initiative boosts your chances of starting encounters first.

Level 8: Great Weapons Master Feat

Level 8 is your next stop to unlocking one of the best Feats for Karlach and her Barbarian Class in BG3. At this point, you should pick the Great Weapons Master for its damage and status-effect buildup, and since you’ll likely have accumulated several accuracy-raising items and potions.

Show Full Text

1. Great Weapons Master (or GWM) primarily causes damage over time with its Bleed buildup, which cuts off 2 Slashing Damages at the start of each enemy turn.
2. When you land a critical hit or kill an enemy with a melee attack, you gain an additional bonus attack in the same round.
3. If you’re dual-wielding weapons in your build, you get a +10 damage bonus instead of a -5 penalty of a regular Barbarian, a benefit you can efficiently utilize for Karlach thanks to her generous Carry Weight.
4. For better versatility, I recommend turning GWM off for regular attacks, so you use them on lightly armored targets with Advantage or just for the bonus attack if you kill something.

Important: You can also utilize Advantage and Bless from other characters in your party to improve accuracy further.

Level 9/10/11: Additional Features And Actions

At Levels 9,10, and 11, you’ll unlock a series of offensive and defensive utility for Karlach, making her one of the best all-around companions and a worthy part of your Karlach build.

Show Full Text

1. Starting from Level 9, you’ll receive the Brutal Critical feature that further raises a Critical Hit’s importance, as you’ll roll an extra damage die and an additional critical dice with each Critical Hit.
2. It also raises your Critical chance, pairing well with the GWM and improving your chances of getting a complimentary bonus attack.
3. For Level 10, players will unlock the Intimidating Action, a Class Action that inflicts enemies with Fear, causing them to have a Disadvantage on their Ability Checks and Attack Rolls.
4. Finally, at Level 11, you’ll gain access to Relentless Rage, another Class Feature that, once per Short Rest, lets you regain 1 HP when you lose all health.
5. This is more of a passive ability that effectively gives Karlach another fighting chance and keeps her alive.

Level 12: Rage And Savage Attacker Feat

Level 12 is the maximum level for Karlach and any other character in Baldur’s Gate 3. Here, you’ll unlock some Additional Rage to better maneuver around the battlefield and utilize your abilities and an extra Feat ability. For the most part, Karlach’s been a damage powerhouse with several attack rolls per turn, and to build up on that, the last and ideal Feat for her is Savage Attacker.

Show Full Text

1. With Savage Attacker, you roll your damage dice twice and use the highest result when making a weapon attack.
2. This is a perfect addition to this build, as you’ll mainly be doing melee damage with melee weapons anyway, and with up to 4 attack rolls per turn, you can frequently select the more lethal options. 
3. Not only that, but these extra rolls also increase your Critical Chance so that you can gain an additional bonus attack from Great Weapons Master.

My Experience And Tips For Using Karlach

Karlach is a Tiefling barbarian with a fiery heart for destroying things (quite literally.) In most of my playthroughs, I mostly go with the Bear Heart Feat and Halberd weapons for reckless but easy critical hits. It is not her “best” build, but if you’re a new player or someone who disregards health (like me), this build will do wonders for you because of her self-healing and easy mobility.
