Baldur’s Gate 3: Best Karlach Companion Build

This guide will explain the best Karlach Companion Build in Baldur’s Gate 3, the Barbarian class, the Berseker subclass, and the best setup.

Baldur's Gate 3 Karlach

Karlach Companion Introduction

Karlach is a powerful Zariel Tiefling Barbarian who admires strength in both combat and life. She was once a slave soldier, so it’s likely she has a soldier background. As such, she’s likely to be inspired and approve of acts of kindness toward the oppressed, and she’ll solve problems like a true fighter, never showing weakness.

Companions in Baldur’s Gate 3 are a group of non-player characters (NPCs) who join the player’s party and accompany them throughout their journey in the game. These companions are essential characters that offer various benefits, such as providing additional combat support, contributing to the story, and offering different perspectives on the events unfolding in the game world. 

Companions can be avoided entirely, die, be romanced, and have their own sprawling background. In this build guide for Karlach, we will explore her character and how to make a powerful Barbarian using this origin character.

This build has been updated for the latest version of Baldur’s Gate 3

Karlach Companion Features & Mechanics

The following list presents all the essential Karlach Companion Mechanics and Features in Baldur’s Gate 3:

  • Class: Barbarian
  • Race: Zariel Tiefling

How to Find and Recruit Karlach

Baldur's Gate 3 Karlach Location

To find and recruit Karlach in Baldur’s Gate 3 you must head to the south from the Risen Road. You can teleport there if you already have it uncovered, or head north and then east from the Blighted Village. You will find her wounded on the rock. She will explain that mercenaries are after her and will ask you to kill them. Head to the abandoned house next to her location near Risen Road and speak with the mercenary leader. During the dialogue, select “I know the woman…She’s under my protection.” A fight will start and after you defeat the enemies, report to Karlach to complete the quest.

BG3 Berserker Barbarian Subclass

The Best subclass for Karlach build is Berserker Barbarian because it provides some of the most powerful damage actions by a melee class.  The Berserker subclass comes with Frenzy Strike, Enraged Throw and Rage turns into Frenzy.  During early access, Karlach was not a playable Companion but Larian Studios has confirmed she will be a Barbarian.

Here are all the Baldur’s Gate 3 Barbarian subclasses:

Baldur’s Gate 3 Berserker Barbarian Features & Progression

The Berserker Barbarian subclass unlocks the following features and spells:

  • Frenzy Strike (Level 3): As a bonus action, make a melee attack with your Current equipped weapon.

  • Intimidating Presence (Level 10): Menace an enemy and instill a terrible Fear within them. If the target resists this effect, it can’t be targeted again until it Long Rests.

Karlach Race

Karlach by default is a Zariel Tiefling from Zariel’s Bloodline are empowered with martial strength, and can channel searing flame to punish their enemies. They are also often ambitious and ruthless, driven by a desire for power.

Zariel Tieflings are a rare and exotic race, and they often find themselves the subject of curiosity or fear. However, they are also a powerful and versatile race, and they can be an asset to any party.

Zariel Tiefling Racial Features:

  • Base Racial Speed 9m
  • Darkvision: Tieflings can see in the dark within 12 meters.

Karlach Skills - Baldur’s Gate 3

Athletics and Survival are the best skills for the Karlach in Baldur’s Gate 3 because they complement your class abilities and enhance your effectiveness in various situations. In Baldur’s Gate 3, skills represent the abilities and proficiencies of your character that allow them to perform various actions and interact with the game world. Skills are associated with specific attributes and are used to determine the success or effectiveness of certain actions or abilities.They can be edited during character creation or with companions, during respec or reroll screen.

Here are the skills for Karlach in Baldur’s Gate 3:

  1. Athletics is a Strength Skill
  2. Survival is a Wisdom Skill

Karlach Ability Score

Here’s the best ability score for the Baldur’s Gate 3: Best Karlach Companion Build:


The Best Ability Score for the Karlach Companion Build is high Strength of 16 and Constitution of 16 that way your melee abilities will do a lot of damage with a massive health pool for good survivability. The next priority is Dexterity at 14 so you have a higher initiative because going first or sooner means eliminating more enemies and taking less damage. Dexterity also gives us +2 Armour Class (AC) due to a Barbarian passive, again, helping us with survivability.

In Baldur’s Gate 3, ability scores are the six core stats that determine a character’s capabilities. For companions, the game automatically distributes them without the ability to change initially. However, you can later change their default ability score in your camp via the NPC Withers for 100 gold.

Karlach Level Progression

Level 1

BG3 Karlach Companion Build
BG3 Barbarian Rage

For companions, the game automatically distributes ability scores and you will want to change that. You can change your default class, ability score, and skills in your camp via the NPC Withers for 100 gold. Use the character creation steps above and hit the appropriate ability score and skills. However, you cannot reset her race. You want to either use medium armor or clothing, and a two-handed weapon preferably Greatsword. You can get a super powerful one in the prologue section called the Everburn Blade.

At level one you will unlock two mechanics as a Barbarian:

  • Unarmored Defense: While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Constitution modifier. You can use a shield and still gain this benefit.
  • Rage: While raging, you deal 2 extra damage with melee and improvised weapons, and when throwing objects. You also have Resistance to physical damage and Advantage on Strength checks and Saving Throws. Rage ends early if you don’t attack an enemy or take damage each turn. You can’t cast or concentrate on spells while raging.

Unarmored Defense helps if you don’t plan on wearing medium armor. You can, however, strip Lae’zal’s armor and equip it with high Dexterity for a higher Armour Class (AC). The advantage to using “clothing” not armor is the gear sets. Later on as you develop, the game will incentivize you with clothing-based gear sets with the Wrath status effect, which increases melee damage. There are risk rewards to this. Less AC means you get hit more, but some of the gear sets are ultra-powerful damage. I suggest starting with Medium higher AC and see how your survivability is. If good, switch to meta clothing sets. We will suggest some in our gear section at the bottom of this build page.

Rage is the bread-and-butter component of The Barbarian. You’ll want to use this on your first time with a bonus action and charge in. Also make sure to equip a ranged weapon so you can always attack once per turn to keep it active.

Gameplay essentially is using your bonus action on your first turn to go into Rage, charging ahead and attacking either with a bow or melee weapon two-handed Greatsword preferred.

Level 2

BG3 Barbarian Level 2
BG3 Barbarian Level 2 Features

At level two you will unlock Reckless Attack and Dangerous Sense. Here’s what they do:

  • Reckless Attack:  Reckless Attack feature, which allows you to gain Advantage on melee weapon attack rolls in exchange for granting advantage to enemies attacking you until your next turn. This should be used against an enemy you will either kill or won’t target you next turn.
  • Dangerous Sense: You have an Advantage on Dexterity Saving Throws against traps, spells, and surfaces. This is just passively applied to your character.

Reckless Attack is your main skill for damage. When you gain advantage, you can roll two dice rolls rather than one and the game selects the highest. This increases damage significantly. Be aware, the enemy will have the same advantage against you too.

Gameplay: At this stage of the game, your goal is to simply use Rage as your bonus action on your first turn in charge into combat. Your goal is to get hit or hit someone and extend the Rage effect. Make sure to equip a bow in case you cannot reach a target on your first turn. Use Reckless the majority of your attacks.

Level 3

BG3 Berserker Barbarian Subclass
BG3 Berserker Level 3 Features

At level three you will finally get to pick a subclass and we recommend Berserker. It takes advantage of your bonus action and gives a great ranged damage ability. Here’s what you should do at level 3 with a Barbarian Build:

  • Take Berserker Subclass
  • Extra Rage Charge
  • Frenzied Strike skill unlocked: As a bonus action, make a melee attack with your equipped weapon.
  • Enraged Throw skill unlocked: Pick up an item or creature and throws it at a target, dealing Bludgeoning damage and knocking it Prone. Your Strength affects how much weight you can throw. Heavier items deal more damage. The damage of Thrown Weapons is the same as the Weapon’s melee damage. You also deal additional damage based on your Strength
  • Frenzy: grants you the ability to enter a frenzied rage as a bonus action, allowing you to make an additional melee weapon attack on each of your turns. Note that this feature also incurs one level of exhaustion once your rage ends.

The Barbarian starts to feel powerful at level 3. Here you can use your bonus actions to attack with Frenzied Strike and Enraged Throw. Ideally, on your first turn, you pop Frenzy (formally Rage) and charge into combat to either strike melee or at range. On your second turn, Frenzy should still be active. Here you can make an attack with your action and a second attack with a bonus action. And at levels 4 and 5 you can get even more attacks!

Enraged Throw is my favorite of the two new skills because you can stun or knock an enemy prone. The weakness of the Barbarian is the lack of crowd control, NOT the lack of damage. This skill is essential because it allows us to use primary damage Reckless Attack with our action and stun someone even at range with Enraged Throw. I carry a lot of daggers and spears and use those to throw and pick them up after the fight.

Gameplay now is Frenzy with bonus action on the first turn, charge in for Reckless Attack. On the second turn, use your action first (Reckless) then a bonus action attack like Frenzied Strike or Enraged Throw. Keep in mind, if you use too many bonus action attacks of either Frenzied or Enraged Throw you will lose Frenzy. Be aware, if you use Frenzied Strike or Enraged Throw on every turn, you will get knocked out of Frenzy. Limit it if possible and will have more utility with our bonus action later.

Karlach’s race Zariel Tiefling unlocks another skill for us at level 3 Searing Smite.

Searing Smite: 1d6 fire damage a target with Searing Smite takes 1d6 icon bg3 wiki guide 11d6 Fire damage every turn, until it succeeds on a Constitution saving throw.

BG3 Zariel Tiefling Level 3

This skill is typically used on Paladin builds but can be useful due to the damage over time. The downside is it uses an action and a bonus action. This consumes our entire turn but can proc some additional damage which can be useful if you have a high percentage to hit and you just need that extra oomph. I typically shy away from this skill on my Karlach Barbarian build but it’s an option and free once per long rest.

Level 4

BG3 Barbarian Ability Improvement Strength 18

Take the Ability Improvements Feat and put two points into strength. At level four you want to increase your strength to 18. This will help you with consistent damage. We don’t recommend Great Weapon Master feat at this level. The reason is, the Barbarian with the Berserker Subclass makes great use of their bonus action because of Frenizy Strike and Enraged throw. So, go for the simple and effective increase in stats.

Nothing new happens gameplay-wise yet, but you should be hitting harder and have a better chance to hit. We will get another feat at level 8 and 12. We will take Great Weapon Master at level 8 because we make good use of our bonus action at this current level and want a higher chance to land attacks early.

Level 5

BG3 Level 5 Barbarian
Baldur's Gate 3 Extra Attack

At level five the Barbarian gains extra attack and Fast Movement.

  • Gain the Extra Attack feature, allowing you to make two attacks when you take the Attack action on your turn. This significantly boosts your damage potential in combat.
  • Gain a Class Feature Fast Movement increases your movement speed by +5 while not wearing heavy armor.

At level 5 the Barbarian becomes amazing with Extra Attack paired with Frenized Strike. This will allow you to attack multiple times with your actions and another with a bonus action. You can drink a Potion of Speed for a further effect and do a lot of damage in one turn.

This is where the Barbarian starts to dominate. Your first turn is the standard, bonus action to activate Rage/Frenzy and charge in with Reckless Attack. If you land the attack you get an additional one. Usually, you want to use your secondary weapon-based skill like Lacerate to cause some bleeding damage. On the second turn, you will have a bonus action free, so you can do 2x attacks, the first being Reckless then use a bonus action strike depending on the range. That’s three attacks per turn. If you are doing a hard fight, use a Potion of Speed and you add another 2 to that!

Karlach’s race also gives us another skill at this level, Branding Smite.

BG3 Zariel Tiefling Level 5

Branding Smite: 2d6 radiant damage possibly marks your target with light, preventing it from turning Invisible.

This ability is typically used on Paladin builds and can be useful for preventing invisibility. The downside for it on our build, like Searing Smite, is it uses an action and a bonus action. This essentially consumes our turn, but can hit extremely hard and prevent invisibility.

Level 6

BG3 Level 6 Barbarian

At level 6 of the Barbarian, you get an additional Rage charge and a subclass feature Mindless Rage.

Mindless Rage: Your rage becomes all-consuming, repelling outside influence. While Frenzied, you cant be Charmed or Frightened, and Calm Emotions no longer ends your rage. This helps you become immune to annoying crowd control effects and keeps you from losing damage or missing turns. Outside of that, combat is more of the same at this point.

Level six you should be towards the end of act one depending on how many quests you did.

Level 7

BG3 Level 7 Barbarian

At level 7 the Barbarian unlocks Feral Instinct

Feral Instinct: You have honed your instincts to the utmost degree. You gain a +3 bonus to Initiative and can’t be surprised.

While this doesn’t seem big, it’s absolutely vital to the build. You will have a high Initiative and skip Surprised which eliminates your first turn. This means you are guaranteed to go during the first round of combat and will be one of the first to start. You can then focus on stunning or eliminating the highest priority target and reduce damage for you and your team.

Level 8

BG3 Great Weapon Master Feat
Baldur's Gate 3 Great Weapon Master All In Toggle

At level 8, the Barbarin gets to take another feat, and we suggest Great Weapon Master here.

Great Weapon Master feat which does the following: When a melee attack scores a critical hit or kills a creature, you can make another melee attack as a bonus action. When attacking with Heavy Weapons you are proficient with, attack rolls take a -5 penalty, but their damage increases by 10. This is a high-risk reward feat, but expect huge damage.

The Great Weapon Master feat does two things for you. One, it has a high risk high reward ability to add 10 damage BUT -5 attack roll penalty. As shown in the picture above, this simply reduces your chance to hit the percentage significantly. You can turn this off in the Passive section on your toolbar, which will give you the normal percentage.

Secondly, this feat gives you another chance to hit on a kill or critical hit using a bonus action. This is the real reason the feat is so strong, multiple attacks in a turn, and with this build, you will be getting a lot of critical hits and kills. Combat should therefore be initiated using your action first, saving your bonus action for a Great Weapons Master attack.

Assuming you critically strike or kill a target, you want to start using your bonus action for Great Weapon Master attacks rather than Frenzied Strike or Enraged Throw. This will help keep you in Frenzy for the duration of combat. If you must stun a target or you don’t proc this effect, still use those two alternative bonus action attacks.

Level 9

BG3 Level 9 Barbarian

At level 9 the Barbarian unlocks a class feature called Brutal Critical.

Brutal Critical: When you land a Critical Hit, you roll an extra damage die as well as the normal additional critical dice.

The gameplay is very simple beyond this level and not much changes besides passive benefits like Brutal Critical. As you can imagine, this gives use even more damage and isn’t something we have to activate, it’s a passive feature. Making the Barbarian ultra-simple and powerful.

Level 10

BG3 Barbarian Level 10
BG3 Intimidating Presence

At level 10 the Barbarian unlocks an action-based skill Intimidating Presence.

Intimidating Presence: Menace an enemy and instill a terrible Fear within them. If the target resists this effect, it can’t be targeted again until it Long Rests

This an odd skill that I don’t use much. It requires action and only does fear, which gives disadvantage. Typically I don’t focus on debuffing targets with this build and use support classes for this. You can try this skill, but I’m not a fan.

Level 11

From level 11 to 12 the Barbarian doesn’t get much. I recommend spending the last two levels multi-classing to the Fighter. At level 11 the Barbarian gets Relentless Rage which mimics the Half-Orc passive Relentless Endurance. If you drop to 0 health, you have 1 health instead of being Downed. At level 12 you will miss a feat where you can take +2 Strength, which admittedly is nice. But you can consume Hill Giant potions and reach 21 or 27 strength for a brief time. 

The reason I suggest multi-classing Karlach is purely for Action Surge. A resource used once per short rest ability that gives you another action in combat.  Given the Barbarian already has extra attack, those extra two attacks combined with Great Weapon Master is worth sacrificing Relentless Rage and +2 Strength. If you do not wish to do this, continue and take the Ability Improvement +2 Strength at level 12 with Karlach.

  • Great Weapon Fighting Style: When you roll a 1 or 2 on a damage die for an attack with a two-handed melee weapon, that die is rerolled once. This is an amazing benefit only Paladins and Fighters have. You get a reroll low damage die increasing your output potential significantly. 
  • Second Wind: this skill is unlocked at level one Fighter and is a mediocre heal that is useful during the start of the game. You can use a bonus action, though most potions outperform it.

If your multi-class, this level will feel uneventful, but trust me it’ll be worth it.

Level 12

Baldur's Gate 3 Barbarian Fighter Multi Classing Level 12

With two levels into Fighter, you get access to the awe-inspiring Action Surge. You get an extra action, but the biggest strength is, it doesn’t require any resource to use it. Action Surge is a once-per-fight usage, but it allows you to cast and recharges on short rest.

So, you now have Karlach with Great Weapon Master feat, Extra Attack and give her Action Surge for 2x more attacks. You can take this a step further by using either a Potion of Haste or casting Haste on her, as well. Then you get another action! If you did the math on that:

  • Attack one + extra attack = 2
  • Attack two (via Action Surge) + extra attack = 4
  • Attack three (via Haste) + extra attack = 6
  • Great Weapon Master via critical strike or kill = 7 (if you have a bonus action)

Karlach at level 12 with this setup has so much firepower it’s remarkable. Again, if you want to stay entirely in the Barbarian class for all 12 levels, take Ability Improvement +2 Strength or the Alert feat which helps with going early. We hope you enjoyed this build and check out the gear section for more!

In Games like Baldur’s Gate 3, you’ll explore the world, loot chests and your enemies’ dead bodies, and complete quests, and all those activities can reward you with useful items, potions, armor, weapons, scrolls, and much more. There are three Acts in BG3, and we’ve updated this guide to include suggested sets and alternatives for Act 1 and Act 3.

Karlach Combat, Gameplay Tips, and Tricks

Here are 10 gameplay tips specifically for playing Karlach Companion in Baldur’s Gate 3:

  1. Use Rage Wisely: Activate this and stay aggressive. You need to either do damage or be damaged so play up close.
  2. Initial Turn: Make sure your initial move either puts you in melee range so you can strike or attack with range to keep Rage active.
  3. Bonus Action: Once you get Frenzied Strike, you can attack with a bonus action, using two attacks in one turn so don’t waste it.
  4. Prioritize melee combat: Use different weapons based on their strength and unique skills, like Cleave for Area damage.
  5. Manage Frenzy wisely: Make sure you have at least two charges left on your Frenzy so that if you are disabled or lose the buff, you can require it during a long fight.
  6. Reckless Attack: use this attack when it’s likely you will not receive a return blow.
  7. Potion of Speed: use these potions to gain bigger movement and more actions in challenging fights.
  8. Enraged Throw: this skill can be useful when you need to keep Rage or Frenzy active, but don’t have the movement.
  9. Long Rest: Make sure to rest when your Rage and Frenzy counters are low so you start with many available.
  10. Great Weapon Master: try to target low-health enemies with a high chance to hit so you can proc a free extra attack if you kill them.

Remember, this build guide serves as a foundation, and you can always adapt it to suit your preferences and the needs of your campaign. Enjoy playing as a formidable Barbarian with the best Karlach Companion Build!
