Infernal Iron Quick Summary Infernal Iron is a rare, otherworldly metal essential for completing Karlach's companion quest, "The Hellion's Heart," and crafting the Flawed Helldusk armor set. It can be found across all three acts of the game, primarily in heavily guarded or hidden locations.
Infernal Iron is a unique material in Baldur's Gate 3, described as a metal originating from the Nine Hells. Visually, it appears as a dented piece of black metal with a persistent red shimmer. Players who interact with it may notice faint, haunting screams, reflecting its infernal nature. Beyond its aesthetic properties, this item serves as a critical resource for both story progression and equipment upgrades.
For those looking to optimize their gear or delve deeper into character stories, this guide outlines the specific locations where you can secure this resource and how to utilize it effectively.

The Importance of Infernal Iron
Infernal Iron is most famously associated with the companion Karlach. In her personal quest, "The Hellion's Heart," this metal serves as the key component required to stabilize her infernal engine. By providing the material to the blacksmith Dammon, players can unlock the Heart of Iron passive feature for her.
Beyond its necessity for Karlach, the material is highly valued by crafters. When delivered to Dammon at the Last Light Inn, he can use the alloy to forge specialized equipment, specifically the Flawed Helldusk Armour and the Flawed Helldusk Helmet. These items provide significant defensive benefits, making the search for this metal a priority for players aiming to improve their party's survivability.
Where to Find Infernal Iron
Infernal Iron is dispersed throughout the game world, appearing in Act 1, Act 2, and Act 3. Because the item is often hidden in restricted areas, players should be prepared for combat or stealth challenges when hunting for it.
Act 1 Locations
In the early stages of the game, you can find Infernal Iron in two primary areas:
- Blighted Village: Search the forge basement. The item is located inside a chest at the named location; verify the current map.
- Shattered Sanctum: Locate the treasure crates belonging to Dror Ragzlin at the named location; verify the current map.
If you are currently navigating the early game, you might find it useful to check our /locations/baldurs-gate-3-map to better visualize the path to these locations.
Act 2 Locations
As you progress into the Shadow-Cursed Lands, keep an eye out for these spots:
- Reithwin Mason’s Guild: A piece can be found at the named location; verify the current map.
- Gauntlet of Shar: Search for an Opulent Chest located in the vault room near the area where you encounter Balthazar. The coordinates for this find are the named location; verify the current map.
Act 3 Locations
In the final act, the metal becomes accessible through more dangerous means:
- Flymm Cargo’s Basement: Look on the floor at the named location; verify the current map.
- Lower City: The item is carried by Steel Watchers patrolling the streets of Baldur's Gate. You will need to defeat these constructs to loot the material.
Crafting and Quest Usage
The primary utility of the Infernal Iron rests with the NPC blacksmith, Dammon. His ability to work with this hellish material is limited to specific instances based on your progress in the game.
Karlach's Questline
The most crucial use for the metal occurs in the Druid Grove. By giving a piece of Infernal Iron to Dammon during your time there, you initiate the upgrade process for Karlach's infernal engine. This is a vital step in her story, allowing her to retain her humanity and gain the Heart of Iron passive feature. Failure to provide this material early on can impact her narrative arc significantly.
Smithing the Flawed Helldusk Set
Once you reach the Last Light Inn in Act 2, Dammon expands his smithing capabilities. If you provide him with the metal, he will craft the Flawed Helldusk equipment in a specific order:
- Flawed Helldusk Armour
- Flawed Helldusk Helmet
These items are considered high-tier for mid-game play, offering protection that fits the aesthetic and mechanical requirements of most martial classes.

Managing Your Inventory
Because Infernal Iron is a quest-related item, it is generally recommended to keep it in your inventory rather than sending it to your camp chest. This ensures that when you encounter Dammon, you are ready to initiate the dialogue for crafting or quest progression immediately. Note that the game sometimes refers to items such as "Infernal Alloy" or "Infernal Metal" in similar contexts; always check your journal to ensure you have the correct material for the specific quest objective you are currently pursuing.
Source-aware planning notes
Item guidance is most reliable when it records where the collected sources agree and leaves uncertain properties unfilled. Make a small checklist for the objective, compare the source wording, and avoid treating an attributed value, drop chance, or interaction as confirmed unless the snapshot supports it. Official updates can change item behavior, so preserve the date and re-check before relying on a detail in a new run. Use the article's headings as a worksheet: write down the confirmed premise, the next action, and the point at which you need to verify a newer source. This approach keeps the guide useful for a first pass while making its limits visible. It also prevents a concise community summary from being mistaken for a complete rulebook. When you adapt the advice to a different party, difficulty, platform, or patch, preserve the original wording and add your own observation separately. A careful note is more valuable than a confident detail that the collected evidence cannot support.
FAQ
Is Infernal Iron the same as Infernal Alloy?
According to the collected notes, Infernal Alloy is listed alongside Infernal Iron as a related term. While both are used by Dammon for similar crafting purposes, you should verify which specific item your quest log or dialogue prompt is requesting before attempting a craft.
Can I get infinite Infernal Iron?
The collected guide identifies specific, finite locations for Infernal Iron across the three acts. There is no mention of a reliable respawn mechanism for this item. Players should prioritize using the found pieces for the most critical upgrades, specifically Karlach’s quest, before using any surplus for crafting armor.
What happens if I miss the Infernal Iron in Act 1?
The source data confirms that Infernal Iron is available in Act 1, Act 2, and Act 3. If you miss a piece in an early act, you may still find additional pieces later in the game. However, because Karlach's quest requires the item early to progress her story, it is highly recommended to secure the Act 1 pieces as soon as you reach the Druid Grove.
Where is the best place to use Infernal Iron?
The most important use is for Karlach's companion quest, "The Hellion's Heart," which requires the item to be given to Dammon. Once her quest is satisfied, the best use for any remaining pieces is to have Dammon craft the Flawed Helldusk Armour and Helmet at the Last Light Inn.
