Baldur’s Gate 3: Best Astarion Build Guide

Best Astarion Build Baldur's Gate 3 cover

Astarion is one of the ten BG3 companions you can recruit or one of the six origin characters you can play as. This vampire spawn can lack a moral compass which makes him handy to be around situations that require some underhanded tactics. Use this guide to make the best Astarion build in Baldur’s Gate 3.

Best Astarion Build in Baldur’s Gate 3

The best Astarion build centers around his Thief subclass which gives him the ability to commit bonus actions per turn. This gives him a lot of versatility to do a lot within a small amount of time. Keep his default class as a Rogue to gain access to this subclass and its potent abilities.

Astarion is locked as a high elf whether you’re playing as him as one of the origin characters or as a companion. You can’t change his race but it does play rather well for this build. High elves come with several benefits that make playing as Astarion easier.

For starters, high elves have Darkvision which lets them see further into the darkness. This makes Underdark expeditions a bit easier compared to races who don’t have it. They also get their free pick for a cantrip in the wizard spell pool. Because of their Elven Weapon Proficiency, they’re amazing with longbows, shortbows, longswords, and shortswords.

Astarion is also unique among your companions because of he’s a vampire spawn. This comes with the ability to bite any living creature to restore Hit Points. Doing so won’t break you out of stealth which is insanely useful.

BG3 Astarion Build – Best Class

The best class for Astarion is the Rogue. He’s already one by default. Being a Rogue means that Astarion is a master of technicalities dealing high single target damage but it does require a lot of strategic thinking to play efficiently.

Rogues are a class that utilizes underhanded tactics to get the upper hand on their enemies. They’re a versatile class that highly excels in stealth, taking out targets unaware, and striking foes before they can have the chance to fight back. Rogues are essentially pragmatists by nature.

You can respec Astarion’s class by talking to Withers at your camp. For a fee, he’ll allow you to change almost everything about him. This is what you should make Astarion out to be:

  • Race: High Elf
  • Class: Rogue
  • Subclass: Thief
  • Proficiencies: Stealth, Acrobatic

BG3 Astarion Build – Best Ability Score

For Astarion’s Ability Score, you should make it like this:

  • Strength: 12
  • Dexterity: 16
  • Constitution: 16
  • Intelligence: 13
  • Wisdom: 8
  • Charisma: 10

As a Rogue, the most important stat to invest in is Dexterity as this stat is the primary that the class revolves around on. However you should also invest in Constitution for extra Hit Points. Intelligence is a good third priority as the subclass that we’ll choose needs it as a Saving Throw.

BG3 Astarion Build – Best Subclass

The best subclass for Astarion is the Thief. This subclass gives you the ability to move around the battlefield freely and stealthily while allowing you to take Bonus Action every turn. Here are the features you can expect from this subclass:

  • Fast Hands: Gain an additional Bonus Action
  • Second-Story Work: Gain resistance to Falling Damage halving it.

Thief is the go to subclass for Rogues as Arcane Trickster and Assassin are rather lackluster. They’re Fast Hands is one of the most potent abilities in the game as an extra action per turn is incredibly beneficial. With this feature you can choose to move further, drink potions, engage in stealth, and whatever you want to do.

The Second-Story Work isn’t as useful as their first feature but still great in certain situations. You don’t need to be as considerate with fall damage for Astarion so moving around isn’t going to be a problem.

BG3 Astarion Build – Level Progression Guide

As Astarion progresses through levels, he gains access to new skills courtesy of his Race, Class, and Subclass. Here’s what we recommend you do per level:

Level 1

At Level 1, Astarion will get two actions courtesy of his Rogue class. Here’s what you can expect for this level:

  • Sneak Attack: For both melee and ranged, Astarion gets an additional 1d6 damage against enemies he has an Advantage against. You’ll get +1d6 damage for every 2 levels of Rogue.

Sneak attacks are done usually by striking an enemy when hidden. They can also trigger when attacking targets within 3m that are Prone or when they’re 1.5m near an ally. Restrained enemies also give you Advantage. It won’t trigger if you have Disadvantage.

As a bonus, Astarion can use Vampire Bite to restore his health. This will require a Long Rest per use so best used in emergencies. This also doesn’t break Stealth so you can feed on enemies without exposing yourself.

Your main focus should be getting into stealth while letting your allies deal with enemies. Once they’re within 1.5m of your party’s tank, you strike and gain bonus damage thanks to Sneak Attack. Because of this, we recommend you go with bows for this one and use a Barbarian like Karlach to attract enemies.

Level 2

When Astarion gets to Level 2, he gets Cunning Actions which are bonus actions you should take advantage of. Here’s what you can expect for this level:

  • Cunning Action: Hide – Let’s Astarion hide from enemy sight by passing a Stealth check.
  • Cunning Action: Dash – Doubles Astarion’s movement speed.
  • Cunning Action: Disengage – Moving won’t trigger Bonus Attacks from enemies.

Level 3

At Level 3, you can finally pick the Thief subclass. This grants you the class features that you need for this build, Fast Hands and Second-Story Work.

You’ll be utilizing Fast Hands a lot for an extra action every turn. Second-Story Work is more situational but can be useful when you’re constantly moving Astarion around high places. It won’t take away fall damage completely, but it reduces it significantly.

Level 4

At Level 4 you can pick a feat that gives Astarion an additional feature. While you can choose to increase his Ability Score instead, we recommend going for the Sharpshooter feat instead as this is excellent for this build. Here’s what it does:

  • Sharpshooter: Ranged weapon attacks don’t suffer from High Ground Rules. Attacks with ranged weapons Astarion is proficient in receives a -5 to their Attack Roll but the damage is increase by +10.

This feat is pretty much a requirement for any character going for a ranged build. Since we’re focusing on Astarion as a ranged damage dealer by taking advantage of his proficiency in longbows, shortbows, and crossbows the Sharpshooter is the most ideal feat to pick.

Level 5

At Level 5, you’ll get a class feature for Rogue. Here’s what you can expect at this level:

  • Uncanny Dodge: When attacks hit you, you only take half the usual damage.

Level 6

At Level 6, you can add 2 expertise to Astarion’s proficiencies. You should invest in proficiencies that revolve around the Dexterity stat. Here’s what we recommend you invest in:

  • Deception
  • Sleight of Hand

Level 7

At Level 7, Astarion gets a class feature. Here’s what you can expect at this level:

  • Evasion: Astarion can dodge certain spells on Dexterity Saving Throws. A successful dodge means taking no damage while a fail only gives him half damage.

Level 8

At Level 8, you can pick another feat again. However you should invest into your Dexterity points instead of picking one. While Mobile and Skilled are incredibly good picks for a feat, the best option is to increase Astarion’s Dexterity.

Level 9

At Level 9, Astarion gets a new action thanks to his subclass. Here’s what you can expect for this level:

  • Supreme Stealth: Blend into the environment so perfectly that you’re practically invisible.

Level 10

At Level 10, you get to pick a feat. We recommend taking Skilled and using it to invest proficiencies in heavy crossbows. It opens up new ranged options for Astarion to use.

Level 11

At Level 11, you get a Rogue class feature. Here’s what you can expect for this level:

  • Reliable Talent: Ability checks with skills you are proficient in can’t roll lower than 10.

Level 12

At Level 12, you can pick another feat. We recommend taking the Lucky feat as you can get 3 Luck Points that you can use to reroll your attacks and Saving Throws including Ability Checks, or force an enemy to reroll their Attack Rolls potentially saving your from a devastating hit.

BG3 Astarion Build – Best Gear

This build for Astarion should be using ranged weapons like longbows, shortbows, and hand crossbows. After reaching higher levels, you can invest in a feat that lets him become proficient with heavy crossbows. This is only enhanced by Sneak Attack (Ranged) to help him deal more damage.

For armour, you should be looking for ones that help him move faster or increase his Dexterity. As a Rogue, Astarion has proficiency for Light Armour which is better for him since he doesn’t need heavier protection so long as you utilize stealth to his advantage.

How to Recruit Astarion in Baldur’s Gate 3?

You can recruit Astarion by heading west of the Nautiloid crash site where you find yourself shortly after the prologue. Talk to him and he’ll tell you about a Destroyer he wants you to kill. Accept, and he’ll pounce on you instead. Keep peaceful and pass several checks and you’ll be able to invite him to your party.

As Astarion joins your party, a scene will play at the camp where he’ll ask to suck your blood. Agree and you’ll earn approval from him. However it is possible to die in this scene if you keep failing the skill checks. You need to pass Persuasion and Strength checks to survive this encounter.
