Finding rare materials in Baldur's Gate 3 is essential for upgrading your party and progressing through crucial companion questlines. Infernal Iron is a highly sought-after resource primarily used to repair Karlach's hellfire engine and forge powerful heavy armor pieces with the help of Dammon the blacksmith. Tracking down these hidden metal pieces requires exploring dangerous locations across the early acts of the game.
Discovering Iron in the Blighted Village
The earliest opportunity to acquire this precious material occurs in the ruined settlement known as the Blighted Village. Adventurers should head inside the ruined blacksmith's workshop and look for a locked wooden hatch leading into the basement below. Once inside the dusty cellar, you must navigate carefully to find a heavily secured chest tucked away in the back corner.
Opening this container requires a successful lockpicking check using thieves' tools or finding the correct key hidden nearby. Inside the chest lies your first piece of hellish metal, which can instantly unlock new dialogue paths with companion characters. This area serves as an excellent introduction to how rewarding thorough environmental exploration can be.
Searching the Goblin Camp Shattered Sanctum
Another reliable piece of this dark resource is locked away deep within the heart of the Goblin Camp. Players must venture past the guards and enter the absolute deepest chambers of the Shattered Sanctum where the goblin leaders reside. You will need to confront or bypass the formidable chieftain named Dror Ragzlin to access his personal stash.
Directly behind his ornate throne sits a massive locked iron gate that protects the faction's most valuable treasures. Picking this lock or looting the key from the chieftain's body grants access to the wealth hidden within the stone vaults. Among the piles of gold and magical artifacts, a piece of dark iron rests inside one of the wooden crates.
Exploring the Depths of the Grymforge
As your journey takes you deeper into the treacherous Underdark, additional opportunities to collect this heavy alloy will present themselves. After boarding the duergar boat and arriving at the ancient Grymforge, players can interact with various historical experts in the area. Speaking with a specialized vendor named Mason Kith will initiate a unique conversation regarding the architecture of the ruins.
Passing a series of automatic perception, history, or investigation checks during his dialogue will impress the master craftsman deeply. If you successfully analyze the ancient stonework, he will reward your keen intellect by handing over a piece of iron for free. This alternative method allows non-combat characters a peaceful route to obtaining the necessary crafting materials.
Utilizing Your Infernal Supply
Once you have gathered enough metal fragments from these scattered locations, you must return to a skilled infernal mechanic. Dammon can be located at the Emerald Grove during the first act or later at the Last Light Inn as the story progresses. Handing over the salvaged material allows him to stabilize Karlach's heart or forge the rare Flawed Helldusk armor set for your fighters.
It is wise to hang onto any extra pieces you discover during your lengthy travels across the wilderness. Later acts may introduce additional crafting recipes or trade opportunities that reward you for managing your inventory effectively. Keeping your eyes peeled for hidden chests will ensure your companions remain unstoppable throughout the adventure.
