Throughout the party's travels in , you'll encounter many different treasures and materials, such as Infernal Iron. While some of these can be sold for gold, others are needed for quests, which is definitely the case for any pieces of Infernal Iron. These chunks of metal play a key role in companion Karlach's personal questline but can be sometimes tricky to track down.
As the name suggests, infernal iron is directly from the Nine Hells and has special properties. While there are other Infernal metals dotted around, such as seemingly useless Infernal Alloy. Infernal Iron has a purpose within the plot, and it is used for equipment. With the metal being so important to Karlach and only a few pieces in each act, it's important to know where each one is.
Baldur's Gate 3 has tons of loot for players to find, some of which don't always have an immediately apparent use but should definitely be held onto.

The first two are relatively easy to find organically and get to with only minor obstacles. However, the other two are a little trickier and require some planning to get your hands on them.
