Dammon's Forge in Baldur's Gate 3: A 2026 Guide to Infernal Iron and Flawed Helldusk Gear
In Baldur's Gate 3, Dammon turns Infernal Iron and Devilfoil Masks into the Flawed Helldusk set—here's every material location.
As a longtime Baldur's Gate 3 player, I still make a beeline for Dammon every time I start a new run. The tiefling smithy first appears in the Druid Grove during Act One, but his real value hits in Act Two, when I find him working in the central barn at Last Light Inn. He is essential for Karlach's romance and personal story, yet I have learned that his forge is also a treasure chest for any party that hoards Infernal Iron and Devilfoil Masks. In 2026, with the game's patches settled and the community still debating builds, Dammon remains one of the best crafting NPCs in the Sword Coast. I do not need to kill a cambion for his best gear; I just need the right materials and a little patience.
Why I Keep Coming Back to Dammon
Dammon sells a lot of good gear in his trade shop, but his handcrafted items are the real prize. His shop inventory changes by act, and I can always find something useful, yet the Flawed Helldusk set is what makes him unforgettable. The catch is that Karlach's quest also demands Infernal Iron, so I need to plan ahead. If I want every piece of Dammon's craftable set without risking Karlach's story, I aim for at least five pieces of Infernal Iron or Infernal Alloy. That sounds like a lot, but Act One, Act Two, and Act Three are generous if I know where to look.
Where I Find All Materials for Dammon
Here is the grid I use in my own runs. It marks every Infernal Iron, Infernal Alloy, Infernal Metal, and Devilfoil Mask that matters for Dammon's crafting.
| Item | Location | Act |
|---|---|---|
| Infernal Iron | Blighted Village, inside the house leading to the spider cave | 1 |
| Infernal Iron | Shattered Sanctum, inside the treasure chests behind Dror Ragzlin | 1 |
| Infernal Iron | Zhentarim Basement, but I need to deal with or sneak past the guards | 1 |
| Infernal Alloy | Bought, rewarded, or stolen from Stonemason Kith in Grymforge | 1 |
| Infernal Iron | Reithwin Mason's Guild | 2 |
| Infernal Metal | Gauntlet of Shar, inside a chest nearby where I first met Balthazar | 2 |
| Infernal Metal | Stolen from or dropped by Yurgir | 2 |
| Infernal Iron | Flymm Cargo's Basement | 3 |
| Infernal Iron | Iron Throne, on a table right next to the submersible | 3 |
| Infernal Iron | Dropped by Steel Watchers, either when slain or when deactivated | 3 |
| Devilfoil Mask | Grymforge, near the dig site where Nere is trapped | 1 |
| Devilfoil Mask | Grymforge, past the rubble with the Deep Rothe | 1 |
| Devilfoil Mask | Grymforge, at an altar on the way to Grym, guarded by a Merregon Legionnaire | 1 |
| Devilfoil Mask | Grymforge, dropped by the Merregon Legionnaire | 1 |
I always double-check the Zhentarim Basement because those guards can turn a quick pickup into a full fight. I also mark the Grymforge masks early, since one mask equals one Orthon Explosive later.
Flawed Helldusk Armour: My Frontline Favorite
The chest piece requires one Infernal Alloy or Infernal Iron. I usually grab the Infernal Iron in the Blighted Village cellar during Act One. The entrance sits behind large locked doors under the first building, and I have never regretted taking the detour.
Flawed Helldusk Armour is a lesser version of the Helldusk Armour set, but it still packs a punch. It has 18 AC, counts as Heavy Armor, and grants Lesser Infernal Retribution and Superior Plate. Lesser Infernal Retribution has a chance to deal 1d4 Fire damage when an enemy within two meters hits me. Superior Plate reduces Piercing damage by one. The downside is Disadvantage on Stealth checks, which is a fair trade for a tank. It sells for 3,200 gold, but I keep it because each set piece adds extra damage modifiers to my attacks.
Flawed Helldusk Gloves: Ideal for Monks
If I find another piece of Infernal Alloy or Infernal Iron, and Karlach does not need it, Dammon can craft a pair of Flawed Helldusk Gloves. I often find the next piece behind the Masons Guild in Reithwin Town during Act Two.
The gloves come with Lesser Infernal Touch. My primary weapon deals an extra 1d4 Fire damage. If I am unarmed, the gloves deal 1d4 Necrotic damage with a chance to inflict Bleeding. They also give +1 to Strength Saving Throws. I like them best on a Strength-proficient character, because they add damage on top of regular melee attacks without forcing me to change my whole build.
Flawed Helldusk Helmet: Light on Weight, Heavy on Value
The helmet also costs one Infernal Alloy or Infernal Iron. I can get another piece in Grymforge by speaking with Stonemason Kith and passing the ability checks when I agree to analyze the rubble.
The Flawed Helldusk Helmet is not considered Heavy Armor, which makes it easier to slot into more builds. It has Magic Durability, giving a +2 bonus to Saving Throws against spells. It counts as Medium Armor and adds +1 to Constitution Saving Throws. Alone, it is okay. As part of the full set, it becomes much stronger for a raging, Strength-proficient tank.
Orthon Explosives: You Look Better Without the Mask
Dammon can craft up to four Orthon Explosives, depending on how many Devilfoil Masks I bring him. One mask equals one explosive. I find the masks scattered around Grymforge in the Underdark during Act One. They have an interesting Strength buff if used correctly, but I usually sacrifice them for explosives once my party is strong enough.
An Orthon Explosive is a one-use item that deals 3d6 Fire damage and inflicts Burning for four turns. It also deals Fire and Thunder damage as AOE to nearby objects. Dammon warns me about using it, and he is right. The blast consumes the masks, so I make sure I really want grenades before giving up the helmets. The explosive requires a Dexterity Saving Throw, and I save it for tough fights with multiple enemies in one spot. I do not want my party nearby when it goes off. Since I get access in Act Two, I save these for Moonrise Towers or Shar's Temple.
My 2026 Verdict
In 2026, Dammon is still a must-visit for me. He is not just a Karlach quest NPC; he is a forge that turns Infernal scraps into a full armor set and some of the nastiest explosives in Baldur's Gate 3. I check his inventory, I hoard every piece of Infernal Iron, and I never forget the Devilfoil Masks in Grymforge. If I plan around Karlach's needs, I can walk away with the Flawed Helldusk set and a few Orthon Explosives, ready for whatever the Absolute throws at me.
