In Baldur's Gate 3, helping Karlach stabilize her overheating Infernal Engine is one of the most rewarding companion quests available. To repair her heart and advance her personal storyline, players must locate a skilled tiefling blacksmith who acts as her specialized infernal mechanic. Finding this crucial character across different acts requires specific steps to ensure he stays safe and available.

Locating Dammon in Act 1 at Emerald Grove

During the first act of the game, players can discover the infernal mechanic named Dammon in the Emerald Grove. He is stationed inside the area known as The Hollow, set up near a makeshift blacksmithing forge. Bringing Karlach and a piece of Infernal Iron to him allows Dammon to perform her initial engine repair.

It is vital to resolve the grove's political conflict peacefully by eliminating the goblin leaders rather than raiding the sanctuary. Siding with the goblins or starting a war inside the grove will result in Dammon's death, permanently locking you out of Karlach's questline. Completing his request early ensures he will safely travel toward the next region.

Finding Dammon in Act 2 at the Last Light Inn

In Act 2, Dammon relocates to the Shadow-Cursed Lands and establishes a new forge at the Last Light Inn. Players can locate him inside the small workshop building situated on the northern side of the sanctuary compound. If you saved the tieflings during Act 1, Dammon will safely welcome you and continue his work on Karlach.

Handing over a second piece of Infernal Iron allows Dammon to install a vital upgrade for Karlach's engine. This second maintenance procedure stabilizes her body temperature and allows her to physically touch others without causing fire damage. Keeping the Last Light Inn protected from enemy attacks is essential so Dammon survives into the final act.

Tracking Down Dammon in Act 3 in Baldur's Gate

Once your party reaches the sprawling Lower City of Baldur's Gate in Act 3, Dammon can be found running the Forge of the Nine. His shop is located in the central portion of the city, positioned just east of the Devil's Fee. Players can visit him here to browse high-tier equipment and complete any remaining interactions regarding Karlach.

Although Dammon cannot completely cure Karlach's engine condition due to its inherent limitations, visiting his city forge provides final narrative closure. He can also craft specialized heavy armor pieces using leftover material you collect during your adventures. Ensuring Dammon survives all three acts guarantees access to some of the finest crafted gear in the game.
