Welcome to our Eldritch Blaster Build Guide for BG3. This is a Multiclass build that combines the Sorcerer class with elements of the Warlock and Fighter classes. We’ll be playing into the Eldritch Blast Cantrip as much as possible to blast enemies with huge amounts of Force Damage every turn.
The Eldritch Blaster Build buffs the Eldritch Blast Cantrip with as many extra projectiles and as much extra damage as possible.

Eldritch Blaster Multiclass Build Overview
For our Eldritch Blaster Build, we are combining the Sorcerer class with some levels from the Warlock and the Fighter. The Sorcerer class allows you to boost your spells with powerful Metamagic features, and the Draconic Bloodline subclass boosts your elemental damage.
In contrast, Warlock gives you access to the Eldritch Blast,
Eldritch Invocations and
Hex combo, which is probably the strongest Cantrip setup in the game and gives you a powerful and reliable source of consistent damage. These classes work well together because they both favour Charisma as their most important ability.
Towards the end of the game, we add the Fighter class to get Action Surge and increase your Critical Hit chance.
This means that we have to be sure that the payoff of adding new classes to your build is worth it, because every level of a secondary class reduces the highest level we can reach with our primary class.
In this Eldritch Blaster Multiclass Build, we’ll be combining the following classes:
Here is a quick overview of which class we pick when, this is important!
Eldritch Blaster Character Creation (Level 1)
In this section, we will guide you through the best starting choices for creating your BG3 Eldritch Blaster Multiclass Build.
Starting Class (Sorcerer)
We’ll start by choosing the Sorcerer class. The Warlock and Fighter elements of the build will be added later.
The Sorcerer starts the game with the following features, which we’ll build on over the course of this guide:
Best Race
While this build will work fine with any race in the game, there are a few choices that stand out above the rest and can be chosen if you want to optimize the build as much as possible. Here are the five best race choices for the Eldritch Blaster Build:
| Race | Strengths | Info |
|---|---|---|
Wood Elf |
|
Wood Elves are one of the best races in BG3 thanks to their increased Movement Speed, which can give you an edge in many situations.
Their immunity to Sleep is especially useful in the early-game, where your low HP will cause you to fall victim to enemy mages who love to cast the Sleep spell. You can also choose Wood Half-Elf, which comes with many of the same benefits and gives you proficiency with Shields. |
|
High Elf |
|
Very similar to Wood Elf, but missing the Stealth Proficiency and doesn’t get extra Movement Speed. You can choose an extra Cantrip to learn, which is handy but not super important. |
Duergar |
|
With their wide choice of armour and weapon proficiencies, and resistances to poison, charm, and paralysis, Duergar are one of the strongest races in BG3.
The only downside of Duergar is their small stature – this reduces their base Movement Speed to 7.5 metres per turn (most races get 9 metres). |
Drow |
|
Drow have similar bonuses to other Elves, but also come with a couple of extra Spells and Superior Darkvision. |
Human |
|
The Human race is useful because you get an extra Skill pick and additional Carrying Capacity.
You also get Shield Proficiency, which is useful if you want to equip a Shield for extra armour. |

Background & Skills
For your Eldritch Blaster Multiclass Background, we recommend choosing Entertainer.
The Entertainer background gives us the following Skill Proficiencies:
You can manually choose three other Skills in addition to those granted by your Background.
Choose any Skills that are based on Charisma or Dexterity. We went with Intimidation and
Persuasion, which will give you an easier time in many dialogue rolls.
If you’re a Human, you’ll get one extra unrestricted Skill Choice, which you should put in any remaining DEX or CHA skill.
Ability Points
For both the Sorcerer and Warlock classes, the most important ability is Charisma, used to determine the effectiveness of our spellcasting. We will be focusing on this ability above all others.
Other important abilities are Dexterity, which boosts our Armour Class, and Constitution, which increases our Hitpoints and improves our Concentration Checks.
Strength – 10 Points
- Improves jump distance and carry weight.
- Low priority for this build.
Dexterity – 16 Points
- Boosts Armour Class (AC) and Initiative.
- Helps you act sooner in combat.
Constitution – 14 Points
- Increases Max HP.
- Vital for Concentration Checks to keep spells active.
Intelligence – 8 Points
- Not relevant for our build.
Wisdom – 10 Points
- Used in some Saving Throws.
- Low priority.
Charisma – 16 Points
- Primary stat.
- Boosts our Cantrips, Spells and dialogue checks.
| Ability | Points | Why it matters |
|---|---|---|
| 10 | Mostly for jump distance and carry weight. Low priority for this build. | |
| 16 | Important: Gives you a higher Armour Class and improves initiative. | |
| 14 | Important: Increases HP and helps Concentration checks for spells. | |
| 8 | Not relevant for our build. | |
| 10 | Helps with some Saving Throws. Low importance for this build. | |
| 16 | Our primary stat. Boosts Cantrips, Spells and dialogue checks. |
Spells
To start with, you’ll need to select two first-level Spells for your character to learn. We recommend going with the following options for our Eldritch Blaster Build:
Cantrips
In addition to the Spells, you’ll need to choose four Cantrips. These are less powerful spells that do not consume a Spell Slot when cast, meaning you can generally cast them every turn if you want to, with no limitations.
We recommend choosing the following Cantrips for your Eldritch Blaster build:
Subclass – Draconic Bloodline
You must choose your Sorcerer subclass immediately. I strongly recommend choosing Draconic Bloodline because you’ll get extra defences and an elemental damage boost later in the game.
Alternative: Another viable option is the Shadow Magic subclass. Later in the game, it can summon a Hound of Ill Omen to support you in combat. But you get less armour than Draconic Bloodline, so you’ll need to get the
Mage Armour spell and use it after every Long Rest.
BG3 Eldritch Blaster Multiclass Build Levelling Guide (2-12)
Now, we are going to look at how to level up your Eldritch Blaster Build for Baldur’s Gate 3.
Early-Game Levelling (2-4)
In this section, we’ll cover the first four levels.
Level 2
For this level, we will already add the Warlock class to the build. The image above shows where you need to click to add a new class.
Adding the Warlock class to your build gives the following benefits:
You can choose 2 Warlock Cantrips to unlock. It is imperative to choose Eldritch Blast, as this will be a vital part of this build:
You can unlock two Warlock Spells, which will be cast using your new Warlock Spell Slot:
You can now spam Eldritch Blast, which allows you to deal reliable damage from range without spending Spell Slots.
To get the best out of the build, remember to combo Eldritch Blast with your new
Hex spell.
Level 3
We will add another Warlock Level to the build here, allowing us to quickly rack up a lot of extra power from Eldritch Blast.
Taking two Warlock levels so early gives you a strong, reliable tool to fight with in the early-game, and one that scales up very nicely over the course of your playthrough.
You’ll need to choose two Eldritch Invocations. These are special abilities that let you further customise your Eldritch Blaster build.
We strongly recommend choosing the following two options:
Level 4
We will now return to the Sorcerer class.
Make sure you switch back to the Sorcerer class before confirming your level up! See the image above if you don’t know where to click.
You unlock a new resource called Sorcery Points. These are spent to activate Metamagic powers, and can be replenished by Long Resting. You’ll also gain +1 Sorcery Point at every Sorcerer Level up.
Metamagic – Choose 2:
You can also unlock a new spell. We recommend:
Mid-Game Levelling (5-8)
In this section, we’ll cover the mid-game. During these levels, the Eldritch Blaster Build will become much more powerful, accessing a wider array of spells.
Level 5
We’re adding another Sorcerer Level, giving you a total of Sorcerer Level 3 and Warlock Level 2 so far.
You’ll now unlock some better Sorcerer spells and an additional Metamagic power.
You can choose another Sorcerer spell to learn:
Level 6
We’re adding our fourth Sorcerer level here.
This will give you access to a Feat to improve your Eldritch Blaster’s stats, and another new spell.
First, let’s choose a new spell:
Level 7
We’ll now add the fifth level of the Sorcerer class to our Eldritch Blaster Build.
This is quite a simple level in terms of what you unlock. As usual, you get a new Sorcery Point. Besides that, you get one more spell.
Level 8
We’re adding the sixth Sorcerer Level to our Eldritch Blaster, taking the total to 6 Sorcerer, 2 Warlock.
This level is important because you will unlock the most defining features of your Sorcerer subclass.
Alternative: If you picked the Shadow Sorcery subclass, you’ll now unlock the Hound of Ill Omen. Be sure to summon him before starting combat!
Late-Game Levelling (9-12)
We will now finish off the build by adding the Fighter levels, increasing your attack rate and damage.
Level 9
It’s time to add the first Fighter level to the build.
The first Fighter level will bring you the following new features:
Level 10
We will now add a second Fighter level to the Eldritch Blaster Build.
This gives you one very important new feature.
Level 11
We’ll add a third Fighter level now.
You’ll need to choose your Fighter subclass – we recommend choosing the Champion subclass to increase your critical hit chance.
Level 12
This is the maximum level for the Eldritch Blaster Build. We will add one last Fighter Build, which unlocks a second Feat slot.
We will unlock a new Feat to increase your Critical Hit rate with Eldritch Blast and other Spell Attack Rolls.
This Feat combination allows you to equip the Blade of the First Blood in your offhand slot (explained properly in the Equipment section below) to further increase your Crit chance.
BG3 Eldritch Blaster Build Equipment
Now, let us take a look at some of the equipment choices you can make for your BG3 Eldritch Blaster Build.
Don’t worry if you miss out on some of the items. Just enjoy your playthrough and try to view this as a wishlist rather than a precise blueprint.
Early Game Equipment
This is the early-game gear setup that you can use for your Eldritch Blaster Build. You don’t need to get all the items, but the build will perform better if you find most or all of them. You can find these items in Act 1 or early Act 2. Essential items are written in Bold Italic.

Phalar Aluve |
|
Stuck in a rock in the Underdark. Requires a Strength or Religion check to free it. |
We aren’t using a ranged weapon because it isn’t required – you’re best off using your spells and cantrips to deal ranged damage.
The most important items here are the two weapons, The Spellsparkler and
Phalar Aluve. These combine to add heaps of extra
Lightning and
Thunder damage to each projectile from your Eldritch Blast.
Most of the other items are intended to either synergise with these bonuses or to give general buffs to your defensiveness.
For example, Gloves of Belligerent Skies add the Reverberation effect when you deal
Lightning or
Thunder Damage, which will quickly stack up for even more
Thunder Damage as well as debuffing your enemies. The
Ring of Absolute Force adds a little extra Thunder damage into the mix.
The Protecty Sparkswall gives you a small buff to your Armour Class and Saving Throws whenever you have a Lightning Charge. Once you have the Spellsparkler, this will be pretty much all the time.
Important: Most of the bonuses here also work with the Magic Missile spell, so you can use that when you need a big chunk of extra damage. That spell is especially nice because it cannot miss, and most enemies can’t block it. We have a somewhat similar build that focuses on boosting Magic Missile: BG3 Magic Missile Build Guide
Endgame Equipment
The endgame gear for the Magic Missile Build can be obtained either in late Act 2 or Act 3 of Baldur’s Gate 3. If you manage to complete all the items below, you will be an unstoppable force of power. Essential items are written in Bold Italic.

Here is a summary of how these items work together to boost this Eldritch Blaster Build for Baldur’s Gate 3:
As you can see from our distribution of attacking vs defensive-minded items, this build can be a bit of a glass cannon. Since we are a ranged combatant, keep this in mind and keep your Eldritch Blaster as far from enemies as possible while still being able to hit them. Utilize line-of-sight obstructions to block enemy ranged attacks when possible.
We have three items reducing the Critical roll requirement. In combination with the Champion subclass and the Spell Sniper Feat, you only need to roll 15 to crit with Eldritch Blast. This, combined with the Risky Ring giving you two shots at every roll, means that you will be landing an insane amount of crits with this build.
Eldritch Blaster Build Extra Info
Here is some extra information that will help you to get the most out of this Eldritch Blaster Build in Baldur’s Gate 3.
How to Play this Eldritch Blaster Build
Early-Game Basics
We only need two Warlock levels for this multiclass build, and we opted to add them very early in the game because you get quick access to the Eldritch Blast &
Hex combo, further buffed by the
Agonising Blast and
Repelling Blast Invocations.
From Level 2 and above, you can cast Hex on an opponent and then keep hitting them with
Eldritch Blast to deal consistent damage. If you maintain Concentration, you can recast
Hex on a new target later on, without spending another Spell Slot.
This simple combo will be your bread and butter for most encounters. The Sorcerer class gives you a wider range of spells than what the Warlock alone would have, including buff spells, debuffs for enemies, and some good AoE spells. Keep in mind that other spells requiring Concentration cannot be used at the same time as Hex.
Another important Sorcerer spell is Scorching Ray, which works similarly to
Eldritch Blast, firing multiple rays of fire at enemies. If you have a low hit chance against a target, you can use
Magic Missile, another spell that shoots several projectiles at the target. While it deals comparatively less damage, it benefits from being unable to miss!
When you have unlocked the Dual Wielder feat, be sure to combine the Spellsparkler with Phalar Aluve to add as much extra damage to your Eldritch Blast as possible. This weapon combo will last you until partway through Act III when better options become available.
Finally, note the differences between regular Spell Slots and Warlock Spell Slots:
Maximising the Build for Mid-Late Game
The main purpose of this build is to buff up the Eldritch Blast cantrip, make it possible to cast it several times per turn, and massively increase your Critical Hit chance.
You can use the Haste buff to get two actions per turn and the Sorcerer’s Quickened Spell feature to cast Eldritch Blast with a Bonus Action. This means you can cast Eldritch Blast three times in one turn, potentially even four times if you use the Elixir of Bloodlust.
If you’re not concentrating on an effect like Haste, then it’s still decent to use the Hex spell to boost your Eldritch Blast’s damage ceiling.
It’s important to remember that Eldritch Blaster is a glass cannon damage dealer. They should be kept at long-range as much as possible, and always avoid direct confrontation with enemies.
Play with an evasive playstyle, cast your spells and then get some distance between yourself and the enemies or hide behind an obstruction to protect yourself. The Displacement Cloak gives you some protection against enemy attacks, but as soon as you take even a single point of damage, you will lose its protection until the next turn, so you must stay mindful of positioning so that the Eldritch Blaster won’t get attacked many times on your turn!
Eldritch Blaster Build Illithid Powers (optional)
Illithid Powers are unlocked later in BG3 when you learn more about Mind Flayers and Tadpoles. By eating Jars of Mind Flayer Parasites you gain one point. This is another optional skill tree that you can get access to if you want. Here are some of the best Illithid Powers for the BG3 Eldritch Blaster Build:
Eldritch Blaster Build FAQs
Here are some frequently asked questions related to the BG3 Eldritch Blaster Multiclass Build. Most of these questions have already been answered in the guide itself.
- What’s the best race for the Eldritch Blaster Build?
- What roles can the Eldritch Blaster fill in my party?
- What abilities are most important for the Eldritch Blaster?
- Which subclasses should I use?
FAQ: What’s the best race for the Eldritch Blaster Build?
While any race will work just fine for this build, the best options are:
- Wood Elf – Very high mobility, resistance to effects like magical sleep and Charm, innate Darkvision. The extra Movement Speed is an underrated bonus that allows you to outrun foes.
- Duergar – Gives you innate Superior Darkvision. Allows you to wear Medium Armour. Gives you Resistance to Poison Damage and Advantage against the Poisoned, Charmed and Paralysed effects. This wide range of bonuses makes the Duergar very tough.
- Drow – Similar bonuses to the Wood Elf, but doesn’t have the extra Movement Speed. However, you do get Superior Darkvision and can debuff enemies with Faerie Fire.
For more info about the best races, see the Best Race section above.
FAQ: What roles can the Eldritch Blaster fill in my party?
The Eldritch Blaster is a glass cannon damage dealer. They should be kept at long-range as much as possible, and always avoid direct confrontation with enemies.
Play with an evasive playstyle, cast your spells and then get some distance between yourself and the enemies or hide behind an obstruction to protect yourself. The Displacement Cloak gives you some protection against enemy attacks, but as soon as you take even a single point of damage, you will lose its protection until the next turn, so you must stay mindful of positioning so that the Eldritch Blaster won’t get attacked many times on your turn!
This build does have some options for buffing your team and debuffing enemies, but it isn’t built with this in mind – it’s best if you leave these tasks to others in your team and allow your Eldritch Blaster to focus on what they do best – dishing out relentless damage every turn from a safe distance.
FAQ: What Abilities are most important for the Eldritch Blaster?
- Charisma is the most important ability for your Eldritch Blaster build, because it determines the efficacy of your spells and cantrips and will also boost many of your Skills, such as Persuasion, Performance and Intimidation. Put 16 points in Charisma at the start and increase it later in the game.
- Dexterity is also very important. It boosts your Armour Class and Initiative, allowing you to move earlier in the turn. Put 16 points in this.
- Constitution should always be at least 14 for any build in Baldur’s Gate 3, and this one is no different. This gives you a necessary baseline of HP, and helps you to resist a wide range of hostile effects with Constitution Saving Throws. It also helps you to keep Concentration on spells when you take damage.
FAQ: Which subclasses should I use?
- For the Sorcerer, we recommend the Draconic Bloodline subclass for this build. You get extra Armour Class to help you through the early game. Later on, you’ll gain affinity with your chosen element, allowing you to deal extra spell damage and gain Resistance against that element.
- You can also use the Shadow Magic subclass, which will allow you to summon the Hound of Ill Omen to support your character and distract enemies. If you do that, you’ll have a lower base Armour Class and must use Mage Armour to make up for it!
- For the Warlock, I prefer The Hexblade because it allows you to become Proficient with any weapon in the game (which may or may not be needed, depending on which race you chose), and can debuff enemies with the Hexblade Curse.
- The Fiend is another good choice – It will give you Temporary HP whenever you kill an enemy.
- For the Fighter, it’s very important to choose the Champion subclass. The Improved Critical Hit does a lot for our build, and we don’t need any of the effects from the other Fighter subclasses.
