Three Attacks, No Armor, Insane Damage: Giant Hexblade Barbarian/Warlock Multiclass Guide
Welcome to one of the wildest, most effective multiclass builds in Baldur's Gate 3 — a fusion of raw savagery, arcane might, and uncanny survivability. This is the GIANT Hexblade Warlock Barbarian, with a Paladin twist thrown in for divine destruction. It's brutal. It's busted. And if played right, it can dominate even the toughest Honor Mode encounters.
In this guide, we'll deep dive into how to assemble and pilot this incredibly synergistic build, including stat spreads, subclass choices, feats, gear, and strategic combat sequencing. This build is crafted for players who want the perfect blend of devastating melee output, spell-powered flexibility, and tanky frontline control.
Why This Build Works: Synergy Between Rage, Charisma, and Hexblade
At first glance, multiclassing a Barbarian with a Warlock seems counterintuitive. After all, Rage blocks spellcasting, and Warlocks are quintessential casters. But with careful planning, these classes can complement each other brilliantly:
Hexblade Warlocks let you use Charisma for weapon attack and damage rolls.
Barbarians offer durability, Rage damage bonuses, and Reckless Attack for consistent hits.
Paladin adds Divine Smite, making your crits absolutely brutal.
When layered correctly, this build transforms you into a hulking giant that strikes multiple times per turn, deals colossal damage, and shrugs off hits while casting key buffs pre-combat.
Core Class Progression: When and Why to Multiclass
Start with Barbarian (Level 1-5)
Barbarian is your foundation. It grants you Rage, Unarmored Defense, Reckless Attack, and Extra Attack. Starting as Barbarian also gives you Constitution Saving Throw proficiency — critical for surviving spell-heavy encounters.
Subclass: Wildheart vs. Berserker vs. Giant Barbarian
While Berserker provides more direct offensive power (Frenzied Strike), the Giant Subclass adds a unique flair. You gain bonus throwing damage, a massive physical presence, and access to the Boot of the Giants, letting you punt enemies off cliffs with your bonus action.
Multiclass into Warlock (Level 6-10)
Once you have Extra Attack, jump into Warlock for the Hexblade goodies:
Hexblade's Curse: Bonus damage, crits on 19-20.
Hex Warrior: Use Charisma for melee weapon attacks.
Eldritch Invocations: Customize your build with powerful passive bonuses.
Optional Paladin Dip (Level 11-12)
Dip two levels into Paladin for Divine Smite, a mechanic that lets you convert spell slots into radiant damage on melee hits. Since spell slots are rarely used during Rage, this gives you an excellent outlet for your arcane resources.
Ability Score Spread: Prioritize Survivability and Damage
You want a balance between durability, accuracy, and initiative. Here’s a recommended baseline:
Strength: 10 (dump stat, we’re not relying on it)
Dexterity: 16 — boosts AC (Unarmored Defense) and initiative
Constitution: 14 — fuels HP and helps maintain rage
Intelligence: 10 — leave as-is
Wisdom: 10 — decent saves, not critical
Charisma: 16-18 (bump with feats) — fuels your weapon damage, spellcasting, and key abilities
Must-Have Feats to Enhance the Build
You get three ASI/feat opportunities in this build. Use them wisely:
+2 Charisma: Take early to maximize damage and spell DC.
Alert: Ensures you act early in combat — ideal for pre-emptive smites and battlefield control.
Tough: Not required, but adds durability. If you’re already tanky, consider Great Weapon Master instead for more crit fishing.
Key Warlock Invocations and Spells
While Rage blocks standard spellcasting, you can still cast spells before combat and use non-casting invocations and features.
Invocations:
Devil’s Sight: See through magical darkness.
Agonizing Blast: Optional — you won't use Eldritch Blast much, but still useful outside of Rage.
Beguiling Influence: Great if you're also the party face.
Armor of Shadows: Useless here — you’re not using Mage Armor.
Spells to Prep Before Combat:
Armor of Agathys: Free temp HP + damage retaliation — excellent.
Mirror Image: Doesn’t require concentration, boosts AC dramatically.
Shield: Amazing for burst defense if not raging.
False Life: More temp HP, cast it pre-fight.
Hellish Rebuke: Bugged in BG3 — works while raging. Abuse it.
Paladin Integration: Divine Smite and Utility
Adding Paladin 2 gives you:
Divine Smite: Burn spell slots for burst damage.
Fighting Style: Choose Dueling (if one-handed) or Great Weapon Fighting.
Lay on Hands: Usable during Rage.
Oath Choices:
Oath of Vengeance: Adds radiant damage via Inquisitor’s Might.
Oath of the Crown: Grants team utility and attack bonus.
How to Play This Build: Combat Rotation and Strategy

Rely on Reckless Attack for accuracy
Post Rage or in Control Moments
Use Eldritch Blast or Booming Blade again
Reapply Mirror Image if expended
Essential Gear Choices
Armor and Clothing
You're not wearing armor, so gear that enhances AC via Dexterity, Constitution, or magic is vital:
Vest of Soul Rejuvenation: Heals on successful saves
Deathstalker Mantle: Bonus AC and cool stealth perks
Cloak of Protection: Bonus to AC and saves
Weapons
Shadow Blade: High psychic damage and synergy with mental fatigue
Mara Heskir: Unique bonuses and extra fire damage
Sword of Chaos: Strong crit potential
Accessories
Ring of Protection: Boosts AC
Amulet of Spell Savant: Regain spell slots for smiting
Mask of Soul Perception: Boosts initiative and attack rolls
Gloves and Boots
Helldusk Gloves: Adds fire damage
Bracers of Defense: +2 AC when unarmored
Boots of Stormclash: Applies reverberation
Evasive Shoes: +1 AC
Combat Showcase: What a Round Looks Like
With Mirror Image, Haste, and Giant's Rage active:
AC shoots up to 37+
You make 3 melee attacks per turn at level 10
You can Divine Smite critically for up to 88+ damage
You punt enemies with Boot of the Giants into pits
Survive most damage with half physical from Rage and temp HP stacking
You open with Booming Blade, go into Rage, cleave through enemies, and when spell slots are free, smite them into the next plane.
Mage Hand Trick: Free Healing Potions
Use Mage Hand (summoned before combat) to:
Drop potions near you
Throw healing or utility potions when your action is used up
Set up elemental fields with bottles (oil, water, alcohol)
It shares your initiative, so it can be an invaluable combat tool.
Final Thoughts: Why This Build Breaks the Game
This GIANT Hexblade Warlock Barbarian Paladin is a wrecking ball with finesse. You out-damage fighters. You out-survive tanks. You utility-buff better than some casters. And you can do it all while wearing nothing but magical clothing and a smug grin.
By combining high Charisma scaling, bonus action utility, multiple attack sources, and clever pre-combat spellcasting, you're creating a juggernaut that is nearly impossible to shut down. From Honor Mode to casual play, this build stands tall — literally and figuratively.
🧠 Conclusion: A Multiclass Monster of Mythic Proportions
The Giant Hexblade Barbarian Warlock build in Baldur’s Gate 3 is not just powerful—it’s a walking paradox of savagery and spellcraft. With the durability of a primal berserker, the tactical edge of a warlock’s dark pact, and the explosive damage output of divine smites, this multiclass tears through encounters with terrifying ease. Whether you're looking to solo Honor Mode or become the unkillable frontline menace of your party, this build offers unparalleled synergy.
From absurd AC boosts without a single piece of armor to stacking three devastating attacks per turn, there’s nothing standard about this setup. You’re a tank, a striker, a spell disruptor, and a social manipulator—all rolled into one hulking giant. With careful stat tuning, clever use of rage mechanics, and the right mix of invocations and spells, this character becomes a spectacle of violence and resilience.
Now it’s your turn to test its limits.
❓ FAQ: Giant Hexblade Barbarian Warlock Build (BG3)
Q: Can I use spells while raging?
A: Typically no. Raging cancels most spells. However, pre-casting non-concentration buffs like Armor of Agathys or Mirror Image before raging works beautifully.
Q: Why mix Hexblade with Barbarian at all?
A: Hexblade lets you use Charisma for weapon attacks, bypassing Strength. This allows insane synergy with Rage's defensive boost and offensive pressure.
Q: Is this build Honor Mode viable?
A: With proper planning, yes. Just be cautious with spell timing and rage usage. It's an excellent frontline choice due to its high AC and durability.
Q: When should I take Warlock levels?
A: After Barbarian level 5, where you get Extra Attack and Fast Movement. That’s the perfect point to layer in your Warlock features.
Q: What about Paladin? Isn’t that too many classes?
A: Just two levels of Paladin are enough to unlock Divine Smite, boosting burst damage enormously. It's optional but enhances the build’s lethality.
Q: What’s the best weapon for this build?
A: Mara Heshker is phenomenal for bonus psychic damage and synergy with Hexblade. Alternatively, Shadow Blade or the Sword of Chaos also work well.
Q: What’s the ideal feat progression?
A: Early game: +2 Dexterity. Late game: +2 Charisma. Alert or Great Weapon Master are also good, depending on your preferred combat rhythm.
Q: How do I keep up with spell slot demands?
A: Use items like Amulet of Spell Savant or Shield of Devotion to recover spell slots. Rest frequently and use Divine Smite tactically, not wastefully.
Q: Is this more of a melee or spellcaster build?
A: It’s a hybrid—but skews heavily toward melee. Your spells serve to buff, debuff, or react. Most of your time will be spent smashing skulls, not chanting spells.
Q: Can I still play the party face?
A: Absolutely. With high Charisma and access to invocations like Beguiling Influence, you can lead conversations, manipulate NPCs, and pass persuasion checks with ease.
