Should I Help Balthazar in BG3?

When It Makes Sense

• Good fit: You are playing an evil-aligned, Absolute-serving, or ruthlessly pragmatic character. Balthazar is a necromancer in service of Ketheric Thorm, and agreeing to retrieve the Nightsong for him lets you advance the villainous narrative without immediately turning Moonrise Towers and its forces hostile. This path is consistent with characters who value power, survival, or obedience to the Absolute over idealism.
• Good fit: You want to experience the alternate storyline and see how events unfold if Dame Aylin falls into Thorm’s hands. Baldur’s Gate 3 is designed with meaningful branching paths, and helping Balthazar opens a darker timeline with different combat encounters, dialogue, and consequences later in the game. Players who intend to run multiple playthroughs may choose this option specifically to compare outcomes.

When You Should Avoid It

• Warning sign: You are on a good or heroic playthrough, or you value approval from companions like Gale, Wyll, Karlach, and Halsin. Letting Balthazar take the Nightsong leads to Aylin’s capture and likely death, which these companions typically view as a serious moral failure. The loss of approval can damage friendships and romances that you have built across multiple acts.
• Warning sign: You are romancing Shadowheart or trying to guide her toward redemption. While Shadowheart’s relationship with the Nightsong is complicated by her devotion to Shar, helping Balthazar generally pushes the story toward the darker resolution of her personal quest. If you want to see Shadowheart reject Shar’s cruelty and grow as a character, handing Aylin to Balthazar is usually the wrong move.

Pros and Cons

Pros

• Avoids a difficult immediate fight. Refusing Balthazar triggers combat in the Shadowfell area, where he is backed by undead minions and environmental hazards. Agreeing to help him, even temporarily, lets you bypass this encounter and continue toward the Nightsong without an immediate battle, which can be useful if your party is low on resources or under-leveled.
• Aligns with evil-roleplay rewards and narrative choices. A dark-leaning Tav or Origin character can use this moment to commit fully to the Absolute’s cause, gaining access to story beats, items, and interactions that are otherwise locked. It also avoids contradicting a character who has already sided with the goblins, Minthara, or other antagonistic forces.

Cons

• Dame Aylin is lost as an ally. Aylin is revealed to be the Nightsong, and allowing Balthazar to claim her means she is taken to Moonrise Towers and faces execution. Saving her instead makes her available as a powerful ally during the assault on Moonrise and contributes to the endgame. Losing her weakens your forces and removes one of the strongest narrative payoffs in Act Two.
• Major companion consequences. Good-aligned party members will react with strong disapproval if you hand Aylin over, and some relationships may be permanently damaged. In addition, Aylin’s survival is tied to the fates of several other characters, including Isobel, whose protection keeps Last Light Inn safe from the shadow curse.

Decision Checklist

• What is my character’s moral alignment and roleplay goal? Am I trying to be heroic, villainous, or simply pragmatic?
• Do I want to save Dame Aylin, recruit her as an ally, and keep Last Light Inn and Isobel’s storyline intact?
• Am I pursuing a romance or deep friendship with Shadowheart, Gale, Wyll, Karlach, or Halsin, and how will they react if I side with Balthazar?

Alternatives to Consider

If you are unsure about helping Balthazar, the most common alternative is to refuse him outright and fight for the Nightsong. This preserves the heroic storyline and keeps Aylin alive. Another option is to pretend to cooperate while planning to betray him later, though the practical outcome is often the same as refusing. For players following Shadowheart’s Shar-worshipping path, you may also choose to kill the Nightsong yourself rather than let Balthazar take her, which produces a different set of consequences tied to Shadowheart becoming the Dark Justiciar. Finally, if you simply want to minimize conflict, you can save before the conversation and test both outcomes to see which story you prefer.

Final Recommendation

For most first-time or heroic playthroughs, the better long-term choice is to refuse or fight Balthazar and save Dame Aylin. Doing so preserves a powerful endgame ally, protects Last Light Inn, and keeps good companion relationships intact. Helping Balthazar is best reserved for evil or experimental runs where you are comfortable with darker consequences and want to see an alternate storyline unfold. Because this is a high-stakes narrative decision in a single-player game, the right answer is ultimately the one that matches your character and the story you want to experience.
