Infernal Iron BG3 Act 1: Where to Find It and How to Use It

10 September 2026 | 42

Exploring the initial areas of Baldur's Gate 3 reveals numerous rare materials that play critical roles in companion quests and equipment crafting. Among these valuable resources, Infernal Iron is one of the most sought-after items during the early stages of the game. Securing this dark metal allows players to progress Karlach's storyline and unlock unique crafting opportunities.

Understanding the Purpose of Infernal Iron

Infernal Iron is an extraordinary metal forged in the Nine Hells, possessing unique properties that resist standard forging techniques. In Act 1 of Baldur's Gate 3, its primary purpose revolves around repairing Karlach's overheating hellfire engine. Bringing this material to Dammon, the tiefling blacksmith located in the Emerald Grove, allows him to craft vital upgrades for her.

Beyond helping Karlach stabilize her condition, Dammon can also use spare pieces of Infernal Iron to forge heavy armor pieces for your party. This custom gear provides significant defensive advantages during early combat encounters. Consequently, collecting every available piece in Act 1 gives players a distinct tactical edge.

Where to Find Infernal Iron in the Blighted Village

The earliest piece of Infernal Iron most players discover is hidden within the Blighted Village. Head inside the blacksmith's workshop located near the main entrance of the ruined town. Inside, you will find a covered pit that leads down into a dark subterranean basement.

After dropping into the basement, navigate past the traps and search the wooden chest sitting in the corner. Lockpicking or opening this chest reveals a piece of Infernal Iron alongside various crafting supplies. Acquiring this piece provides an easy entry point for progressing companion quests early in your journey.

Locating Infernal Iron at the Shattered Sanctum

Another piece of Infernal Iron resides deep within the Goblin Camp inside the Shattered Sanctum. Travel toward the back of the fortress where Dror Ragzlin keeps his treasure hoard behind locked iron bars. You can breach this vault by pickpocketing the key from Ragzlin or picking the lock manually.

Inside the treasure room, search the main wooden chest located behind the throne area. The Infernal Iron is stored directly within this stash alongside gold and rare magical items. Grabbing this metal ensures you have sufficient materials even if you miss other locations.

Finding Infernal Iron in Grymforge

For players who explore the Underdark before moving to Act 2, Grymforge offers an additional piece of Infernal Iron. Seek out the Duergar merchant named Stonemason Kith, who stands near the ancient ruins. Engaging in detailed conversation about the surrounding architecture prompts him to reward your observations.

If you pass the skill checks regarding history, investigation, or perception, Kith generously gifts you a piece of Infernal Iron. Alternatively, players can discover another piece near the abandoned forge area by searching hidden chests. Collecting these pieces guarantees that Dammon can complete Karlach's initial upgrades smoothly.

How to Use Infernal Iron with Dammon

To utilize your gathered Infernal Iron, you must visit Dammon while he is actively running his forge. In Act 1, he operates within the Emerald Grove near the tiefling encampment. Speaking to him with Karlach in your active party triggers specific dialogue choices to apply the engine repair.

After completing her first repair, present any additional pieces to Dammon to craft specialized Flawed Helldusk armor sets. If Dammon survives the events of Act 1, he can perform further upgrades later in the campaign. Managing your supply carefully ensures maximum benefit for your entire adventuring party.
