Finding rare materials in the expansive world of Baldurs Gate 3 is essential for maximizing your companion quests and unlocking powerful gear. Among these coveted resources, Infernal Iron stands out as a crucial item required to stabilize Karlach's volatile infernal engine and forge rare heavy armor with the tiefling blacksmith Dammon. Navigating the various acts to secure these components ensures your party stays protected while progressing smoothly through the narrative challenges.
Early Locations in the First Act
The earliest opportunity to secure this rare metal appears when exploring the ruined settlement known as the Blighted Village. Players should head inside the dilapidated blacksmith building and look for a trapped wooden ladder leading into a hidden basement area. Inside this lower room, a locked treasure chest contains the first piece of iron alongside valuable weapon blueprints.
Another reliable deposit is hidden deep within the Shattered Sanctum, which serves as the stronghold for the goblin camp leadership. Adventurers must defeat or bypass the formidable hobgoblin leader Dror Ragzlin to access his personal treasure room located directly behind his throne. Unlocking the gate reveals a massive cache of loot, including a highly sought-after piece of hellish forge material.
For players who prefer underground exploration, navigating the treacherous depths of the Underdark offers another valuable opportunity. Traveling to the ancient stronghold of Grymforge allows you to interact with a specialized duergar mason who is studying the local architecture. Correctly answering his historical questions or passing specific skill checks rewards you with a piece of iron without engaging in direct combat.
Expanding Your Inventory in Act Two
As the narrative transitions into the shadow-cursed lands, the opportunities to collect these legendary materials increase significantly. Upon reaching the relative safety of the Last Light Inn, players can reunite with Dammon to upgrade Karlach's heart. Exploring the surrounding wilderness reveals additional hidden caches tucked away in ruined masonry structures and abandoned trade outposts.
The massive Gauntlet of Shar serves as a major hub for endgame progression in this region and houses multiple pieces of the material. Specialized flesh golem guardians and high-ranking demonic entities within the trials often carry these components upon defeat. Thoroughly looting every gilded sarcophagus ensures you do not miss these heavy upgrade resources.
Additionally, visiting the ominous Moonrise Towers provides alternative methods for industrious players looking to complete their collections. Certain specialized merchants inside the fortress sell these items directly, provided you maintain a positive reputation with the local factions. Defeating high-ranking zealots during infiltration missions also yields extra materials for your blacksmithing needs.
Final Forging and Act Three Availability
Reaching the sprawling metropolitan area of the lower city opens up the final tier of gear modification and companion resolution. Players can locate the specialized forge facilities where advanced mechanical components are manufactured for city defense forces. Investigating the technological blueprints scattered around these industrial areas reveals additional hidden metal reserves.
The central foundry responsible for producing the giant steel watchmen serves as the ultimate hotspot for high-tier loot. Destroying the elite mechanical sentinels guarding the inner chambers often provides pristine components ready for immediate crafting. Utilizing these late-game materials allows Dammon to finalize the most powerful protective armor variants available in the entire campaign.
