Navigating the vast realms of Baldur's Gate 3 requires players to keep a sharp eye out for rare crafting materials that significantly impact companion quests and equipment crafting. Among these valuable resources, Infernal Iron plays a crucial role in advancing Karlach's storyline and securing powerful early-to-mid-game gear. Knowing where to locate this hellish metal across various acts ensures you do not miss vital upgrades for your party.

Primary Uses for Infernal Iron in Baldur's Gate 3

The main purpose of collecting Infernal Iron is to stabilize Karlach's infernal engine through her personal companion quest. By delivering this rare material to Dammon, the tiefling blacksmith, players can help control her rising temperature and unlock new interaction possibilities. Completing these repairs across Act 1 and Act 2 is essential for anyone aiming to deepen their bond with Karlach.

Beyond assisting Karlach, Dammon can also utilize extra pieces of Infernal Iron to craft specialized equipment. During Act 2 at the Last Light Inn, he can forge pieces of the Flawed Helldusk armor set for your party. This gives players a substantial defensive boost during challenging combat encounters in the Shadow-Cursed Lands.

Act 1 Infernal Iron Locations

Players can discover several pieces of Infernal Iron early in their journey through Act 1. The first piece is typically found inside a locked chest within the basement of the blacksmith's house in the Blighted Village. Another piece resides behind Dror Ragzlin's throne inside the Shattered Sanctum within the Goblin Camp.

Additional Act 1 supplies can be retrieved from a boobytrapped chest inside the Zhentarim Hideout near Waukeen's Rest. Furthermore, speaking with Stonemason Kith in the Underdark Grymforge allows you to obtain an Infernal Alloy by passing a series of skill checks. This alternative form functions identically for crafting and quest progression.

Act 2 Infernal Iron Locations

As you progress into Act 2, more opportunities to collect this hellish resource become available throughout dangerous regions. One piece sits openly on a tabletop inside the Reithwin Mason's Guild in the Shadow-Cursed Lands. Searching this facility thoroughly yields a quick and hassle-free pickup for your inventory.

Two additional pieces can be secured while exploring the complex depths of the Gauntlet of Shar. You can open an opulent chest located inside a vault room near Balthazar's quarters to claim one piece. The other piece is obtained by defeating or pickpocketing the orthon Yurgir in the eastern wing of the gauntlet.

Act 3 Locations and Late Game Availability

By the time players reach Act 3, Karlach's primary engine repairs are typically complete, making extra Infernal Iron less critical. However, players seeking additional pieces can still find them lying on the floor in the basement of Flymm Cargo. Defeating Steel Watchers patrolling the Lower City also yields drops of this material upon destruction.

Although its utility decreases in the final chapter, collecting spare pieces allows players to sell them for gold or complete missed crafting recipes. Keeping track of these locations ensures your party maximizes every opportunity throughout the campaign. Proper resource management ultimately paves the way for a smooth playthrough across Faerûn.
