In Baldur's Gate 3, the Warlock class is widely considered to be the easiest caster to learn and play, but that doesn't mean it's not powerful. Warlocks don't have as many spell slots as other spellcasters, but they make up for that with an incredibly powerful Cantrip and access to some of the game's best control spells.

Updated May 25, 2024 by Erik Petrovich: Now that Baldur's Gate 3 has been out for nearly a whole year, players have a pretty good grasp on what choices you need to make to create the best Warlock build BG3 offers.

Warlock Class Introduction & Overview

baldurs-gate-3-companions-wyll-warlock-pact-of-the-blade

Warlock Playstyle & Signature Abilities

"Bound by a pact to an all-powerful patron, warlocks trade their loyalty for supernatural abilities and unique magic."

Warlocks are spellcasters whose power is derived from an external power, usually a Patron Devil or other powerful, enigmatic being. The class has access to a number of powerful spells, mostly themed around control and the powers beyond comprehension, as well as the unique Eldritch Blast cantrip that is the basis of the majority of Warlocks' damage output. It's this cantrip that is almost solely responsible for the Warlock being such a popular multiclass option for other classes.

Baldur's Gate 3: How to Get to Underdark (& All Entrances)

The Underdark takes up an enormous amount of the underground of Baldur's Gate 3's first Act – here are four ways to reach the Underdark in BG3.

Though Warlocks only have a few spell slots for the majority of the game, these slots uniquely refresh with either a Short or Long Rest. It doesn't mean BG3 Warlock builds can be totally carefree when it comes to slinging spells in combat, but it does keep Warlocks going longer than classes that fully rely on their Spell Slots, no matter how many are available. Though Warlocks might not have the versatility of the Wizard, nor the metamagics of the Sorcerer, they do have access to unique otherworldly powers that are the envy of the other spellcaster classes.

Best BG3 Warlock Build: Great Old One Overview & Creation Tips

Baldurs Gate 3 Best Build Warlock Class Guide Character Creation

What Makes The Great Old One the Best BG3 Warlock Subclass?

"Warlocks bound to Eldritch beings in the Far Realms work toward inscrutable goals, gaining strange powers over entropy and the mind."

The Great Old One Warlock is one of the best Warlock builds because of its access to powerful, battle-turning control spells that complement the class spell list. By binding oneself to a pact with the Great Old One, Warlocks gain the Mortal Reminder passive, which makes enemies Frightened on crits.

All Baldur's Gate 3 Ranger Subclasses, Ranked

The Ranger mixes martial prowess with nature magic to great effect in Baldur's Gate 3, and its subclasses offer further benefits.

At Level 1, The Great Old One gives Warlocks access to Tasha's Hideous Laughter or Dissonant Whispers, and then at Level 3, they can use Detect Thoughts and Phantasmal Force. Playing as a Great Old One Warlock means committing nearly entirely to being a spellcaster, so only engage in combat from a distance.

The Great Old One eeks ahead of The Fiend because of its more battle-influential spells. Compared to The Archfey, many differences between the two patrons are mostly aesthetic as they both can control combat very well.

Great Old One Subclass Features – Level By Level

Great Old One Warlock Lvl 1

  • Mortal Reminder
    • Passive Ability
    • Critical Hits cause enemies near target to become Frightened

Great Old One Warlock Lvl 6

  • Entropic Ward
    • Reaction
    • Warlock can give an attacking enemy Disadvantage
    • If the incoming attack misses, Warlock gains Advantage against attacker

    • Grants passive Resistance to all Psychic type damage
  • Thought Shield: Psychic Reflection
    • Passive Ability
    • When the Warlock suffers Psychic damage, the attacker also takes the same amount of damage

Best BG3 Warlock Build: Roleplay & Character Creation Choices

Baldurs Gate 3 Wyll Pact Best BG3 Warlock Race: Githyanki

The Githyanki are a powerful race option for a number of classes thanks to its powerful racial spells granted at levels one, three, and five, as well as the Astral Knowledge ability. Astral Knowledge grants the Warlock proficiency in one ability's related skills, which pairs extremely well with the Warlock's innately high Charisma. With this Githyanki racial ability, which recharges once every long rest, Warlocks have little trouble getting the results they want out of dialogue dice rolls.

The Githyanki give Warlocks an improved Mage Hand from level 1, the ability to improve party member's Jump distance at Level 3, and the Misty Step skill at Level 5 – three extremely useful abilities. Githyanki also give Warlocks armor proficiencies the class wouldn't normally have access to, namely light and medium armor, to further improve their defensive capabilities. It's really an all-in-one race that's hard to pass up in favor of another, weaker option.

Baldur's Gate 3: 12 Starting Character Builds For Beginners

Having a plan for how to level up party members is important in Baldur's Gate 3. Here are some great starting builds for players to consider.

Best Warlock Backgrounds in BG3: Sage or Guild Artisan

The Sage background grants proficiency for Arcana and History checks, and will typically trigger Inspiration when the Warlock engages in the magical elements of the world (like getting to Lorroakan's tower), or figuring out the historical significance of places in the world. This tends to complement a Warlock's own RP choices during dialogues, but they are both Intelligence checks, an Ability Score that Warlocks don't generally put a lot of points into. This can hinder their effectiveness, but on the other hand, having Advantage on these rolls can be much handier than a simple bonus.

However, if you are more prone to engaging in dialogues in BG3, the Guild Artisan background might be a better fit. This background grants proficiency in Insight and Persuasion, and tends to trigger inspiration when making items, repairing areas in the world, or identifying and engaging with artifacts.

Both backgrounds are a good fit for Warlocks, but of the two, the Sage background may be easier to earn Inspiration with.

Best BG3 Warlock Skill Proficiency Choices: Deception and Insight

Warlocks get to choose two skills from a list of seven, but depending on which background you choose, some may not be available. This is because those skills are already given proficiency by the Background. Going with a Sage takes Arcana and History out of the options, leaving five left, while being a Guild Artisan leaves six choices, as Insight will already be covered.

Either way, be sure to have Deception and Insight first and foremost. Deception is great for dialogues, and Insight is incredibly useful for determining NPC truthfulness. If Insight is already covered, then replace it with Arcana, History, or Investigation, depending on what you want your Warlock to be good at.

Best BG3 Eldritch Invocations: Agonizing Blast & Repelling Blast

At Level 2, all Warlocks get to choose two Eldritch Invocations, unique abilities that can grant passive or active skills. At Level 2, only a few Eldritch Invocations are available to choose from, but as Warlocks level up more powerful options become available. Even from this starting point, though, Warlocks can pick up two incredibly powerful passives: Agonizing Blast, and Repelling Blast, both of which empower the Warlock's iconic cantrip Eldritch Blast.

Related
Baldur's Gate 3: Best Level 5 Spells, Ranked

Players can't go wrong with these incredibly useful 5th-Level spells in Baldur's Gate 3.

Eldritch Blast is the Warlock's bread and butter, and Agonizing Blast outright increases the damage of Eldritch Blast by the Warlock's Charisma modifier. This affects each hit, so at later levels when Warlocks get two or three Eldritch Blast beams with each cast, it becomes a seriously powerful spell.

Repelling Blast, on the other hand, doesn't improve the damage of Eldritch Blast. Instead, it gives it the ability to push targets by 4.5m in the opposite direction they are hit. Be sure to position the Warlock correctly so that enemies hit can be reliably pushed off of ledges and into chasms practically for free.

Best BG3 Warlock Feats: Alert, War Caster, and Spell Sniper

  • Alert Effects: You gain +5 to Initiative and can't be Surprised
  • War Caster Effects: Grants two new passive abilities, War Caster: Concentration and War Caster: Opportunity Spell
    • Concentration is a passive that grants Advantage on Concentration Saving Throws
    • Opportunity Spell lets you cast Shocking Grasp on enemies that move away from melee range instead of attacking them normally
  • Spell Sniper Effects: The number needed to roll a Critical Hit for Spells is reduced by 1 (so, instead of hitting a 20, you need a 19 or a 20).
    • Additionally, learn one Cantrip from a select list of level 1 Cantrips.

Best Warlock Multiclass Choices & Builds

Baldur's Gate 3 Bard Playing Music

Players can choose to Multiclass beginning at Level 2. Look for the "Add Class" button on the top right of the level up overview menu – this will open up a new menu where players can choose one of any other class in Baldur's Gate 3 when selected.

Bard Multiclass – Warlock 10/Bard 2

The Warlock, being a Charisma-based caster, tends to do very well when it comes to rolling dice in conversations and crowd controlling enemies. Though speccing into Bard doesn't necessarily improve the Warlock's damage output, by putting just one point into this class, a Warlock can provide even more utility to the party through the Song of Rest and Bardic Inspiration abilities. Two levels grants the Jack of All Trades feature, which grants the player Expertise in two additional skills – perfect for dialogue checks.

Song of Rest gives an extra short rest, which gives the Warlock another way to refresh their limited spell slots, while Bardic Inspiration can be used for some useful support skills. Multiclassing as a Bard and a Warlock makes CC a key part of the character's spell list, so plan to stand back and set up plays for allies rather than getting involved in the fighting first-hand.

Make sure this character is the party's "main" character to take advantage of its strong dialogue skills.

Sorcerer Multiclass – Warlock 9/Sorcerer 3

By putting three levels into the Sorcerer class as a Warlock, players unlock the powerful Metamagic system and two charges, which can greatly improve the class' ability to deal damage with Eldritch Blast. Metamagic lets Warlocks use Quickened Spell and Twinned Spell to great effect, adding additional Eldritch Blast casts or damage, and opening up the potential for a Warlock to double-cast spells like Haste.

Additionally, both classes rely on Charisma, and can both take advantage of a player's high CHA stat without forcing them to invest in others. Three levels in Sorcerer lets players choose a Sorcerer subclass. In this case, the best option is the Draconic Bloodline, because it adds HP and increases Unarmored AC to 13. Many multiclass options grant additional armor proficiencies, but not the Sorcerer.
