Infernal Iron is one of the most critical crafting materials encountered during the opening chapter of Baldur's Gate 3. Securing this rare resource early allows players to advance companion quests and forge powerful equipment before venturing deeper into dangerous territories. Understanding where to find each piece in Act 1 ensures you do not miss vital opportunities to aid your party.
Where to Find Infernal Iron in Act 1
The primary location to find your first piece of Infernal Iron is inside the cellar of the blacksmith's building in the Blighted Village. Players can access this underground workshop through a locked cellar door or by descending through a hole in the floor. Once inside, open the chest located on the upper wooden platform to secure the metal safely.
A second piece of Infernal Iron is stored in the Shattered Sanctum behind Dror Ragzlin's throne room. Lockpick the metal grate leading to the goblin treasure stash to loot the rare material. Additionally, a third piece is hidden within a locked chest inside the Zhentarim Hideout located beneath Waukeen's Rest.
Obtaining Infernal Alloy in Grymforge
While exploring the Underdark, players can acquire a special variant called Infernal Alloy from Stonemason Kith in Grymforge. By passing a series of skill checks regarding the ancient architecture, the stonemason will offer the metal as a reward. Alternatively, players can purchase it directly from his merchant inventory.
Although labeled as an alloy, this material functions identically to standard Infernal Iron for quest purposes. Saving it for gear creation allows Dammon to construct specialized armor pieces later in the campaign.
Primary Uses for Karlach's Companion Quest
The most important application of Infernal Iron in Act 1 is repairing Karlach's overheating Infernal Engine. Players must bring the material to Dammon, the Tiefling blacksmith located in the Emerald Grove's refugee camp. Handing over a piece allows him to perform the initial stabilization procedure on her internal engine.
Completing this initial repair unlocks crucial story developments and grants Karlach useful passive combat benefits. However, Dammon can only perform one upgrade during Act 1 before he moves on with the refugees.
Crafting Gear and Managing Extra Materials
In addition to helping Karlach, excess Infernal Iron becomes valuable for crafting unique armor sets once Dammon relocates. Delivering surplus supply to Dammon in subsequent acts allows him to forge heavy armor, gloves, and helmets with fire resistance.
If you collect extra pieces beyond what is required for personal quests and armor crafting, surplus iron can be sold to vendors for gold. Storing extra pieces in your camp chest ensures you never run short during key narrative milestones.
