Yes, Karlach can be saved in Baldur's Gate 3, ensuring her survival despite the critical condition caused by her Infernal Engine.
Karlach's life is in constant peril due to a powerful Infernal Engine embedded in her chest. This device slowly burns her to death as long as she remains outside of Avernus, a specific section of Hell. To prevent her demise, players must guide her toward a solution that addresses the unique requirements of her infernal heart.
The primary method to ensure Karlach's survival involves her return to her native plane:
-
Journey Back to Avernus: The most definitive way to save Karlach is for her to return to Avernus. While she will still carry the Infernal Engine, the environment of Avernus stabilizes its effects, preventing her from burning to death. This path secures her life, although it means she will reside in the Hells.
- Companionship for the Journey: Karlach does not necessarily have to face Avernus alone. Players have options to accompany her:
- Wyll: Given his own history and connection to Avernus, Wyll is a suitable companion to join Karlach on this return journey.
- Tav (The Player Character): The player's custom character can also choose to accompany Karlach, sharing her fate and ensuring she doesn't face the transition alone.
- Both Wyll and Tav: In certain scenarios, both Wyll and the player character can decide to join Karlach, providing her with dual support as she embraces her new, permanent home in Avernus.
- Companionship for the Journey: Karlach does not necessarily have to face Avernus alone. Players have options to accompany her:
By opting for her return to Avernus, Karlach's life is preserved, allowing her to continue living, albeit within the landscape of the Hells. This outcome is widely considered a successful "save" for her character arc.
