Infernal Iron is one of the most sought-after crafting materials in Baldur's Gate 3, playing a vital role in companion storylines and high-tier equipment crafting. Finding this rare resource requires careful exploration across multiple acts of the campaign. Knowing where to look and how to utilize it effectively ensures your party maximizes its potential throughout the adventure.
Key Locations in Act 1
The earliest piece of Infernal Iron can be discovered in the Blighted Village inside the blacksmith's cellar. Players can access this area by unlocking the wooden hatch or breaking through the cracked floorboards above. Searching the chest hidden behind the spiderweb netting yields your first sample.
Another piece lies within the Shattered Sanctum, situated deep behind Dror Ragzlin's throne room. Adventurers must unlock the locked treasure vault using a key or lockpicks to secure the metal. Additionally, taking down the Zhentarim hideout containers in the basement can reveal more hidden stashes.
Finding Infernal Iron in Act 2
Upon reaching the Shadow-Cursed Lands, players can locate another sample at the Reithwin Tollhouse. Exploring the upper floor of the main building reveals a locked vault containing valuable loot, including a piece of Infernal Iron. Checking daily gaming news often reveals player tips on navigating these tricky shadow hazards smoothly.
The Gauntlet of Shar also holds additional pieces for diligent completionists. Searching the vaults near the trial entrances and looting defeated opponents often uncovers rare crafting items. Keeping a sharp eye out while clearing the complex guarantees you will not miss any opportunities.
Repairing Karlach's Infernal Engine
The primary use for Infernal Iron is advancing Karlach's companion quest, The Hellion's Heart. Bringing the material to Dammon the Tiefling smith allows him to forge upgrades for her internal engine. The first upgrade stabilizes her temperature, allowing her to physically touch others without causing burning damage.
Providing Dammon with a second piece of Infernal Iron grants Karlach complete control over her fiery powers. This upgrade permanently unlocks her ability to consume Soul Coins in battle for temporary combat buffs. Completing both repairs is essential for players wishing to pursue a romantic relationship with her.
Crafting Heavy Armor and Gear
Beyond helping Karlach, spare pieces of Infernal Iron can be handed to Dammon in Act 2 to forge powerful heavy equipment. He can craft pieces of the Flawed Helldusk armor set, including a chest piece, helmet, and gloves. Each item provides impressive defensive passive traits and damage resistances during encounters.
The Flawed Helldusk Armor inflicts fire damage on attackers who strike the wearer in melee combat. Meanwhile, the gloves add bonus fire damage to weapon strikes and unarmed attacks. Saving extra metal ensures your tank characters gain a significant defensive advantage early in the game.
