In Baldur’s Gate 3, players have the opportunity to form deep connections with their companions, one of whom is the fiery Tiefling, Karlach. This guide will walk you through the process of romancing Karlach, a character who has emerged from the depths of hell and carries a burning passion that can be ignited through your actions.

Karlach Background

Karlach, a seasoned warrior, has a unique backstory that adds depth to her character. She has fought her way out of Avernus, the first layer of the Nine Hells, and carries with her an Infernal Engine that is in need of repair. Your journey with Karlach begins when you encounter her on the Risen Road in Act 1. Ensure you have a spot in your party for her to join the fight against Anders. As you continue your adventures with Karlach, strive to increase her approval through heroic deeds and good actions. However, be prepared for conflicts, as she may clash with Wyll, another one of the companions. It’s crucial to diffuse such situations through dialogue to maintain harmony within your party.

How To Romance Karlach

Karlach’s Infernal Engine, her heart, is a significant aspect of her character. It causes intense pain to those who attempt to touch her. To alleviate this, you must embark on a quest to find Infernal Iron, a material that can repair her Infernal Engine. This quest is closely tied to her companion quest arcs: Our Fiery Friend and The Hellion’s Heart.


The first step in this quest is to find a Tiefling named Dammon in the Tiefling refugee camp in Druid Grove. Dammon possesses the knowledge to repair Karlach’s Infernal Engine, but he requires Infernal Iron to do so. This material can be found in various locations in Act 1, including the Goblin Camp/Shattered Sanctum and Grymforge in the Underdark. Once you’ve obtained the Infernal Iron, return to Dammon, who will use it to repair Karlach’s Infernal Engine.

After the repair, Karlach will be able to touch someone, albeit briefly. You can test this by attempting to kiss her, which will result in a spark. Following this, you can suggest a way to cool her off, which will advance her dialogue. This can be achieved by throwing water at her, casting a water or ice spell, or shooting an ice arrow.

As you progress into Act 2 of Baldur’s Gate 3, you’ll need to visit Dammon in Baldur’s Gate. Before you can find yourself inside the city, you’ll be find yourself in the Shadow-Cursed Lands, where you’ll come across the Last Light Inn. Here, Dammon will request additional Infernal materials. These can be found in the Gauntlet of Shar dungeon. Once you’ve obtained these materials, return to Dammon, who will warn you of potential problems. Despite this, you can proceed with your romance with Karlach by returning to your camp and engaging in a conversation with her at night.

However, be aware that your romance with Karlach may face some hurdles. Dammon warns that Karlach’s Infernal Engine will continue to overheat, which could eventually lead to her death. While there might be a cure, Soul Coins, it has yet to be confirmed.


Furthermore, if you attempt to romance other companions simultaneously, you may find yourself locked out of potential romances. Therefore, it’s crucial to consider your actions and decisions carefully. However, you are free to recruit other companions as long as you don’t romance them at the same time.

Despite these challenges, romancing Karlach is a rewarding experience. Her fiery spirit, coupled with her endearing personality, makes her a great companion. Whether you’re seeking a fun romance with a darker overstory or a heartwarming venture, Karlach is a compelling choice.

How To Get Karlach’s Approval In Baldur’s Gate 3

  1. Defending Karlach: When Wyll confronts her at your camp, argue that she is not a devil. It’s advisable to recruit Karlach first without Wyll and have this confrontation in the camp. Notably, every Origin Companion seems to have a liking for Karlach.

  3. Mediating Conflicts: Persuade Zevlor against attacking Aradin and later promise him to negotiate with Kagha about extending the tieflings’ stay in the grove.

  6. Making Moral Choices: Save Sazza’s life and ensure Mizora remains unharmed.
  7. Petting Scratch: A simple gesture of petting Scratch can earn you Karlach’s approval.
  8. Handling Goblins: Persuade Lump the Enlightened to fight for the fallen’s flesh and intimidate Novice Crusher in the Goblin Camp. Take control over Dror Ragzlin to ask your questions.
  9. Dealing with Temptations: Express your distrust towards Raphael.
  10. Protecting the Grove: Assure Halsin of your commitment to safeguard the grove. Later, stand with the Tieflings against Minthara and drive the goblins away from the Druid Grove.
  11. Handling Resources: Hand over the infernal iron to Damon.
