Where To Get Infernal Iron BG3 Locations And Karlach Upgrade Guide
Navigating the sprawling world of Baldur's Gate 3 requires players to invest deeply in their companion questlines to unlock the full potential of their party. One of the most emotionally resonant and mechanically rewarding storylines belongs to the fiery Tiefling barbarian, Karlach, whose mechanical heart depends on rare materials to stay stable. Finding these unique materials allows adventurers to help her survive the harsh climate of Faerun while gaining massive combat upgrades.
Early Scavenging in the Blighted Village
The journey to stabilizing Karlach's volatile internal engine begins in the fractured settlements of Act 1. Adventurers can track down their very first piece of scrap metal inside a heavily shadowed basement located within the northern section of the Blighted Village. Exploring the ruined blacksmith area reveals a locked chest sitting high up a wooden ladder, which contains the valuable component.
Securing this initial piece allows your party to establish a working relationship with Dammon, the talented Tiefling blacksmith. He can easily process the metal to provide the first vital upgrade for Karlach's chest piece, lowering her ambient temperature. Taking time to clear this zone early ensures that you do not miss out on vital relationship milestones before advancing further into the wilderness.
Securing Materials from the Goblin Camp Stronghold
Deep within the Shattered Sanctum, a dangerous network of goblin leaders guards massive amounts of treasure gathered from local raids. Players who successfully defeat Dror Ragzlin can access a heavily fortified treasure vault hidden directly behind the hobgoblin lord's grand throne room. Picking the lock on this secure chamber rewards the party with high-tier loot alongside another piece of essential metal.
Alternatively, players can thoroughly explore the dangerous depths of the Grymforge area located within the Underdark. Engaging with local vendors and searching hidden trapped chests near the ancient forge can yield additional resources. Gathering multiple pieces during the opening act provides excellent security for your ongoing companion progression goals.
Tracking Dammon to the Shadow Cursed Lands
As the narrative transitions into Act 2, players must carefully escort the Tiefling refugees toward safer settlements. You can locate Dammon once again setting up a temporary forge inside the stables of the Last Light Inn. Bringing your accumulated materials to him during this phase triggers the second major phase of the companion mechanical upgrade.
This crucial adjustment allows Karlach to finally experience physical contact with her companions without causing accidental burns. The blacksmith can also utilize extra components to forge rare, high-tier armor pieces for the rest of your active party members. Ensuring his survival through the volatile events at the inn remains paramount for completing the entire storyline successfully.
Advanced Mechanics and Late Game Crafting
Upon reaching the massive gates of the lower city in Act 3, the scale of technology shifts dramatically. Adventurers will discover advanced mechanical enemies operating within the Steel Watch Foundry that carry highly enriched variations of the rare metal. Dismantling these massive sentinels provides the ultimate components necessary for high-end crafting loops late in the campaign.
While the primary engine repairs conclude during the second act, gathering these late-game materials remains highly lucrative for expanding your inventory. Players can trade these advanced pieces for exceptional defensive gear or specialized ammunition at endgame vendor stalls. Managing these resources wisely guarantees that your frontline fighters remain virtually unstoppable during the final dramatic confrontations.
