Welcome to the Best Astarion Build for BG3 (Thief Subclass). Thieves are the undisputed masters of the battlefield’s clock. By unlocking Fast Hands at Level 3, Astarion gains an unparalleled second Bonus Action, allowing him to attack, dash, and hide all in a single turn.
This makes the Rogue Thief one of the most versatile builds in the game, capable of delivering lethal burst damage while remaining completely untouchable.

BG3 Astarion Build Overview
Here we will have general overview of our Astarion build for BG3, such as the basics of the Rogue class and Thief subclass, and how to recruit and respec Astarion. If you already know all of that, it’s best to skip this section.
Rogue Class Summary
Rogues are the main “stealth” class in Baldur’s Gate 3. While other classes can stealth, none encourage and reward this playstyle as much as the Rogue.
Thief Subclass
The Thief subclass is especially adept at sneaking around, and it can use two Bonus Actions per turn. This makes for a perfect synergy with the Rogue’s Cunning Actions, allowing you to make a sneak attack and then retreat into the shadows on the same turn.
Overall, the Astarion Thief Rogue combo has one of the best “Multiple Actions per turn” movesets. Thanks to all his bonus actions, he can defeat high-priority targets before they even get a chance to take a turn!
How to unlock Astarion in BG3
Astarion can be recruited very early in Baldur’s Gate 3. Almost immediately after you crash with the Nautiloid ship at the beach. You can find Astarion here on the map. All you really need to do is head northwest of where you start on the Ravaged Beach.
When you approach Astarion, you have three options.
- Easily. Stand back. (Best option)
- Kill it yourself – you look capable enough.
- Leave.
When you select the second or the third option, he will try to ambush you and slit your throat. Don’t worry it won’t come to that. The first option will also lead Astarion to attack you. However, you won’t have to deal with some checks to get his knife away from your throat.
Either way, the tadpole will connect you and clear things up. After all the talking, you can decide to recruit Astarion into your group.
Why (and How to) Respec Astarion
To follow this build guide precisely, you will need to respec Astarion.
It is up to you when you do this, but I recommend getting it done by the time you reach Level 4.
Here is a quick tutorial in case you don’t know how to respec characters in BG3:
BG3 Astarion Build At Level 1
In this section, we will explain the starting situation of the Astarion Build. You must go to Withers like explained above and respec. This allows us to optimize Astarion better.
You don’t actually need to change your class, but doing this will also allow you to change the ability point distribution of Astarion as if he was new character.
Race Info
Astarion is a High Elf, which gives him access to some extra bonuses:
Proficiency
- Proficiency with
Longswords,
Shortswords,
Longbows and
Shortbows.
- Lets you see in the dark, removing combat penalties that would normally apply in dark areas.
- You have
Advantage on Saving Throws against being
Charmed.
- Immunity to being put to sleep by magic.
Perception
- Perception allows you to choose one Cantrip from the Wizard list to learn, regardless of your class.
- Important: The Cantrip is cast with Intelligence (Wizards main stat).
- Therefore, make sure to select a non-damage Cantrip, because our Intelligence modifier isn’t high.
- Select a utility cantrip like
Mage Hand.
Abilities
With the respec in mind, let’s distribute the Ability points optimally.
Bolded Abilities are essential. The others can be adjusted if you want.
Strength – 10 Points
- Improves jump distance and carry weight.
Dexterity – 16 Points
- Primary Stat.
- Boosts Damage, AC, and Dex-based skills.
Constitution – 14 Points
- Increases Max HP.
Intelligence – 10 Points
- Not very important for this build.
Wisdom – 12 Points
- Boosts Perception and saves against Mind Control.
Charisma – 14 Points
- Improves Dialogue dice rolls.
| Ability | Points | Why it matters |
|---|---|---|
| 10 | Mostly for jump distance and carry weight. | |
| 16 | Primary Stat. Boosts Damage, AC, and Dex-based skills. | |
| 14 | Increases HP. | |
| 10 | Not very important. | |
| 12 | Boosts Perception and saves against Mind Control. | |
| 14 | Improves Dialogue dice rolls. |
Skills
Astarion is locked into the Charlatan Background, which gives automatic Proficiency with the Deception and
Sleight of Hand Skills. For his remaining choices, we focus on maximizing his high Dexterity and utility.
We chose the following Proficiencies:
We’ll also choose the following Expertise:
Now that we’ve explained the starting point of the BG3 Astarion build, we will move onto a step-by-step leveling guide.
BG3 Astarion Build Leveling Guide (2-12)
We will now walk you through the process of leveling up Astarion. Note that the Rogue & Thief is a very linear class and subclass combo in terms of progression. While it offers fewer complex branching choices than other classes, every level gained adds raw power and unmatched reliability to your kit.
Early-Game Leveling Process (2-4)
In this section, we will summarise what you gain at each level up on the BG3 Astarion Build, as well as any recommendations for choices to make when leveling up. We’ll start with the earlier parts of the game, levels 2-4.
Level 2
At Level 2, we gain three very important new Bonus Actions:
Pro Tip: While other classes can perform these abilities, doing so consumes a normal Action rather than a
Bonus Action. This effectively means that the Rogue can Dash or Disengage on the same turn that they attack, while other classes cannot.
Level 3
At Level 3, the build becomes more powerful. You will unlock the Thief subclass and see a significant jump in your damage output.
At Level 3, Astarion gains an additional 1d6 for Sneak Attack Bonus Damage, meaning Sneak Attacks will now do between 2 and 12 bonus damage (instead of 1-6), depending on the damage roll.
The Thief Class gets an extra Bonus Action each turn (which is especially nice in combination with the Cunning Actions above).
The defining feature of this build is Fast Hands, which grants Astarion a permanent additional Bonus Action every turn.
This transforms how you play:
The Thief also gets a 50% Resistance to Falling Damage, which isn’t especially important but can occasionally be useful.
Level 4
At Level 4, we have to choose a Feat for the BG3 Astarion Build. Feats are strong passive effects that can enable a certain build idea or give a stat buff to increase damage or survivability.
Mid-Game Leveling Process (5-8)
We’ll now look at the mid-game levels for our Astarion Build, covering levels 5-8.
Level 5
Level 5 provides a massive boost to both Astarion’s lethality and his survivability. He becomes significantly harder to kill while his attacks grow even more potent.
Additionally, your Proficiency Bonus is increased from +2 to +3, meaning you’ll now get a +3 bonus when rolling for skills that you’re Proficient with.
You also get another Sneak Attack Die, so your Sneak Bonus Damage can now roll up to 18.
Level 6
At Level 6, there aren’t many choices to make.
All you need to do is choose two additional Skills to gain Expertise with.
I recommend choosing the following:
Level 7
At Level 7, Astarion will gain an additional sneak attack damage die, meaning your bonus damage potential from stealth will now be 4-24.
Level 8
At Level 8, you’ll get to choose another Feat for your Astarion Build.
Late-Game Leveling Process (9-12)
Finally, let’s look at the end-game leveling up, covering levels 9-12.
Level 9
At Level 9, Astarion’s Proficiency Bonus is improved to +4. This means you now have a +4 bonus added to rolls for any skills you are Proficient at (or Attack Rolls using weapons you’re Proficient with). This bonus always applies unless you roll a 1 (Critical Fail/Miss).
You gain another Sneak Attack Die here too, meaning your attacks from stealth will now deal 5-30 bonus damage.
New Ability: Supreme Sneak
- Spend an
Action to become
Invisible for up to 10 turns.
Level 10
Unlike other classes, the Rogue gets to choose an extra Feat at Level 10.
Level 11
At Level 11, you’ll gain another Sneak Attack Die, giving your attacks from stealth a possible 6-36 bonus damage.
Pro Tip: If you aren’t already, you should do your best to use the Thief’s extra Bonus Action and Cunning Actions to sneak as much as possible in combat, as the potential damage bonuses from stealth are getting really strong, and if you’re not utilising them, you’re missing out!
Level 12
If you’ve reached this point, then you have finished leveling up your BG3 Astarion Build. Congratulations!
At Level 12, you’ll get to choose one more Feat for Astarion.
We got all of the most important Feats already – the last choice is up to you. Pick one of the two recommended below:
Optional, but you could also go with a Multiclass spec at level 12.
Astarion Thief Build Equipment for Baldur’s Gate 3

Astarion Build Extra Info
Here is some additional information, tips and tricks to help you get the most out of this BG3 Astarion Build.
Best BG3 Astarion Build Tips & Tricks
The Thief is easy to build but requires tactical precision to master. Here are a few tips and tricks that you can try out.
Best Party Composition for Astarion
Astarion has a Neutral Evil moral alignment at the start of the game (with a bit of a Chaotic Evil lean in some situations). While you can use any party composition with Astarion, you’ll have an easier time with characters who match up with his alignment.
This leaves the following four options as the most obvious choices:
Astarion Build Best Potions
Astarion 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 Astarion Build:
