Recruiting Karlach in Baldur's Gate 3 brings immense martial power to your party, but her Infernal Engine requires constant attention to prevent total burnout. Tracking down the specialized mechanic capable of stabilizing her heart is crucial for advancing her personal questline and unlocking potential romance options. Understanding where this skilled artisan moves throughout each act ensures you never miss a vital step in maintaining her survival.
Locating Dammon in Act 1 at the Emerald Grove
Your search for Karlach's infernal mechanic begins in Act 1, where a tiefling smith named Dammon sets up shop. He is located inside the Emerald Grove, residing near the forge opposite the central hollow area. Handing over your first piece of Infernal Iron allows Dammon to perform the initial repair, enabling Karlach to touch others safely.
It is vital that you resolve the conflict between the druids and goblins peacefully to protect Dammon and the refugee tieflings. If the grove falls or the tieflings die during Act 1, Dammon will perish, effectively locking you out of Karlach's quest progression. Completing this early check-in establishes the baseline needed for future engine upgrades.
Finding the Mechanic in Act 2 at the Last Light Inn
Assuming Dammon survives the journey from the grove, you will encounter him next in the Shadow-Cursed Lands during Act 2. He sets up his forge in the stable area of the Last Light Inn, ready to assist your party once again. Bringing a second piece of Infernal Iron enables him to perform a critical second upgrade on Karlach's engine.
This second upgrade stabilizes her internal temperatures significantly and allows her to engage in romantic interactions without overheating. Be sure to protect the Last Light Inn from enemy attacks during major story events. Keeping the haven secure ensures Dammon remains alive to assist you further down the line.
Meeting Dammon in Act 3 within Baldur's Gate
In the final chapter of the game, Dammon relocates directly into the Lower City of Baldur's Gate. Players can find his forge situated near the Forge of the Nine, just down the street from the Elfsong Tavern. While he cannot fully replace her hellish engine, he offers specialized crafting services using any remaining Infernal Iron in your inventory.
Visiting Dammon in the city concludes the primary mechanical repair arc for Karlach's questline. Interacting with him here provides key dialogue insights into her condition and sets up her final narrative decisions. Ensuring he reaches the city safely guarantees access to top-tier armor crafting as well.
Essential Tips for Securing Infernal Iron
To complete Karlach's engine repairs, you must actively collect Infernal Iron scattered across the world. Key deposits and chests containing this rare material can be found in the Blighted Village, the Shattered Sanctum, and Grymforge. Stockpiling extra pieces allows Dammon to craft powerful legendary armor sets during late-game visits.
Long-Term Outcomes for Karlach's Questline
Even after receiving two upgrades, Dammon informs the party that the material plane is ultimately too cold for the engine long-term. Managing her quest line carefully opens up distinct endgame paths for Karlach's ultimate fate. Players must decide whether to accompany her back to Avernus, let her transform, or accept her tragic outcome.
