Should I Kill Lorroakan in BG3?

When It Makes Sense

• Good fit: You have already allied with Dame Aylin, the Nightsong, and want to protect her from being imprisoned and drained for Lorroakan’s immortality experiments. Siding with Aylin turns Lorroakan hostile, and killing him resolves the immediate threat while closing that heroic story path.
• Good fit: Your party can handle a difficult spellcaster encounter and you are willing to give up a late-game arcane vendor for the experience, loot, and story closure that defeating him provides. If you have already purchased the scrolls and gear you need, his death has fewer practical downsides.

When You Should Avoid It

• Warning sign: You still want access to his merchant inventory of high-level scrolls and magical equipment. Killing Lorroakan removes him as a vendor, and you may lose the chance to buy items that are otherwise hard to find in Act 3.
• Warning sign: You are role-playing an evil or self-serving character who would rather profit by handing Aylin over to him. If you kill him early, you lock out the alternate quest reward and potential companion reactions that come from the betrayal route.

Pros and Cons

Pros

• Killing Lorroakan advances the heroic Nightsong storyline and prevents Aylin’s capture, which many good-aligned parties and companions prefer.
• You gain experience, loot from the Sorcerous Sundries confrontation, and the freedom to explore the tower without him as an active obstacle.

Cons

• You permanently lose an arcane merchant in Act 3, which can limit your ability to buy powerful scrolls and gear before the endgame.
• The fight can be challenging, especially with his elemental allies, and companion approval may shift in ways that do not match your romance or story goals.

Decision Checklist

• Have I already bought every scroll, spell, and item I might need from Lorroakan and Sorcerous Sundries?
• Do I intend to side with Aylin, or am I considering the betrayal route for its rewards?
• Is my party prepared for a tough spellcaster battle with crowd-control and elemental resistance?

Alternatives to Consider

If you are unsure, consider siding with Lorroakan temporarily to collect information and rewards, then decide whether to betray him later. You can also pickpocket him for specific items instead of killing him, or simply avoid the confrontation until you have finished shopping and completed other Act 3 quests. Spacing out the decision gives you more time to compare outcomes.

Final Recommendation

Kill Lorroakan if you are committed to protecting Aylin and no longer need his shop. Avoid killing him if you still rely on his merchant inventory or want to experience the betrayal path. Since Baldur’s Gate 3 is a single-player RPG with no real-world stakes, choose the outcome that best fits your character and story, and keep a save file before the confrontation so you can revisit the choice if you change your mind.
