In Baldur's Gate 3, Infernal Iron is a vital resource required for pivotal character progression and special equipment crafting. Understanding where to locate this rare hellish material and how to utilize it properly ensures you do not miss crucial story beats.

Primary Quest Applications for Infernal Iron

The primary use of Infernal Iron centers around Karlach's companion quest, known as The Hellion's Heart. Bringing this rare metal to the Tiefling blacksmith Dammon allows him to repair Karlach's overheating internal engine.

Beyond story progression, Dammon can also utilize extra Infernal Iron to forge heavy armor pieces for your party. Crafting items like the Flawed Helldusk set provides valuable offensive and defensive bonuses during mid-game encounters.

Where to Find Infernal Iron in Act 1

Adventurers can discover their first piece of Infernal Iron inside the Blighted Village basement forge. Another piece is stored inside Dror Ragzlin's guarded treasure room within the Shattered Sanctum.

Additionally, players can navigate the Zhentarim Hideout to locate a trapped chest containing the metal. Completing architectural dialogue checks with Stonemason Kith in the Grymforge rewards an extra piece known as Infernal Alloy.

Key Locations Across Act 2 and Act 3

In Act 2, players can pick up Infernal Iron off a workbench inside the Reithwin Mason's Guild. Exploring the Gauntlet of Shar reveals further pieces inside locked vault chests and as loot from the orththon Yurgir.

By the time players reach Act 3, the core necessity for Infernal Iron diminishes after completing Dammon's crafting options. However, surplus pieces can still be collected from Steel Watchers or found in Flymm Cargo's basement to sell for extra gold.

How to Locate Dammon Throughout Your Journey

To use Infernal Iron, you must track down Dammon as he moves across different regions during the campaign. In Act 1, he resides within the Hollow section of the Emerald Grove refugee camp.

During Act 2, Dammon sets up his forge at the Last Light Inn inside the Shadow-Cursed Lands. Finally, in Act 3, he operates out of the Forge of the Nine located in the Lower City of Baldur's Gate.
