Astarion Companion Guide in Baldur’s Gate 3

Astarion is the vampire spawn Rogue companion and one of the most popular characters in Baldur’s Gate 3. His personal quest — centered on the parasite and his master Cazador — is one of the most morally charged arcs in the game. This guide covers building and recruiting his loyalty.

Class and Role

Astarion starts as a Level 1 High Elf Rogue. He is your stealth, lockpicking, and single-target burst specialist.

• Best build: Thief Rogue (second bonus action) with dual crossbows or shortswords. Take Gloom Stalker Ranger 5 / Rogue 7 for an even stronger stealth archer variant.
• Maximize Dexterity; keep him at range or in stealth for Sneak Attack.

Approval: Likes and Dislikes

Astarion is selfish, sardonic, and values personal freedom above all.

He approves of:

• Cruel or pragmatic choices that benefit him
• Defying authority and moralizing do-gooders
• Letting him feed (early on) and asserting dominance over his own body

He disapproves of:

• Acts of selfless heroism and protecting strangers at cost to yourself
• Refusing his more monstrous impulses

Act 1: The Bite Decision

Early on Astarion asks to bite you at camp. This is a pivotal moment:

• Let him bite you: Grants him approval and a small HP buff, but you lose a bit of health each long rest until resolved.
• Refuse: Lower approval, but no downside.
• Attack/call him out: Can lead to a fight or a different loyalty path.

None of these lock his quest, but they set the tone for his character development.

Final Tips

Astarion’s quest resolves in Act 3 against Cazador. How you handle that fight defines his ending — free him or let him ascend. Keep him stealthed for opening Sneak Attacks, and use his Spider Meat / Daylight immunity (when in shade) to your advantage in bright maps.
