Get Started
Before going further, we should briefly consider what infernal iron in Baldur’s Gate 3 actually is. Simply put, infernal iron in Baldur’s Gate 3 is a type of unique metal that can be used in a couple of different ways within the game, most notably for completing Karlach’s Hellion’s Heart quest and to create Flawed Helldusk Heavy armor, gloves, and helmets. It’s also relatively valuable, selling for 100 gp per piece.
Baldur’s Gate 3 Infernal Iron Locations
Given its potential value in several scenarios, it’s definitely worth looking out for infernal iron during your game. Since Infernal Iron is also available within the early game in Act 1, it’s worth planning your journey early on in your game. Along with early-game decisions such as whether to set up your game on a
private server, looking out for infernal iron from the get-go may make it easier for you to complete Karlach’s infernal engine and change her fate.
Finding Baldur’s Gate 3 Infernal Iron in Act 1
There are four pieces of infernal iron to find within Act 1 of Baldur’s Gate 3, so keeping your eyes peeled right at the start of the game’s pretty important. The four locations in which you can find infernal iron in Act 1 of the game are as follows:
- One piece of infernal iron is found in the Blighted Village forge basement, hidden inside a chest.
- One piece of infernal iron is located within the Shattered Sanctum treasure crates, owned by Dror Ragzlin.
- One piece of infernal iron can be uncovered inside the Zhentarim Basement in a trapped chest, which is hidden behind a locked door.
- One piece of infernal iron can be purchased from the Grymforge Stonemason Kith. Keep in mind that this is sold as an “Infernal Alloy,” but it is still an infernal iron piece.
These are the earliest pieces of infernal iron that you can find in the game. It’s well worth getting hold of these, as Act 1 and 2 are when infernal iron generally proves most useful.
Finding Baldur’s Gate 3 Infernal Iron in Act 2
Once you’ve made it through the first act of the game, there are still plenty of opportunities to get hold of more infernal iron in Act 2. The main internal iron locations in Act 2 of Baldur’s Gate are as follows:
- One piece of infernal iron can be located within the Reithwin Mason’s Guild, which is found in the Shadow-Cursed Lands.
- Two pieces of infernal iron can be found within the Gauntlet of Shar:
- One piece of infernal iron is held by Yurgir, and can be either looted or pickpocketed; he will not give it up willingly. Yurgir’s piece of infernal iron is instead labelled as infernal metal, but the item is still the same.
- One piece of infernal iron is found within the vault room’s Opulent Chest. This chest can be found near Balthazar. Once again, the item is labelled as infernal metal, but it is still a piece of infernal iron.
Given that two of the available pieces of infernal iron are found in the Gauntlet of Shar, it’s safe to say that getting hold of these in Act 2 is a little simpler. However, bear in mind that you’ll need to either kill or pickpocket Yurgir to get his piece of infernal iron, and he’s no doubt a tricky foe to overcome.
Finding Baldur’s Gate 3 Infernal Iron in Act 3
By Act 3, you’ll likely have already found plenty of infernal iron, and so may not need it anymore. Indeed, after Acts 1 and 2 and completing Karlach’s infernal engine quest and crafting the needed armor, there are no more uses of this material; it can still be sold for a small boost, though.
Infernal iron can be found in three locations in Act 3, including the following:
- One piece of infernal iron can be found in Flymm Cargo’s basement. This is one of the easiest pieces to find as it’s simply lying on the floor.
- One piece of infernal iron can be obtained from the Lower City’s Steel Watchers.
- The final piece of infernal iron is available within the Iron Throne in the submersible dock room.
Given that the uses for these infernal iron pieces are somewhat limited by this stage of the game, you may want to sell them to raise funds for the final leg of your adventure.
