All companions in Baldur’s Gate 3 have one issue or another that needs solving. Halsin wants the goblin leaders dead, Shadowheart wants to deliver a package to the city, and Lae’zel wants to find her kin.
Karlach’s problem is her overheating, malfunctioning infernal heart. The one-horned tiefling barbarian is quickly deteriorating, and the only person who can help is Dammon, an infernal engineer of some skill. Here is where to find him.

All Dammon Locations
Dammon is a recurring NPC who can be found in different locations in all acts of the game.
Act 1 Dammon Location
Dammon can be found in the Druid Grove marketplace near Auntie Ethel. He uses a tent as a makeshift blacksmith shop in the center of this area. If you’re having trouble finding him, you can always look for him on the mini-map.
Hover over the name of any NPC you see on the mini-map, and you’ll be able to see their name. This is particularly useful when you’re in a busy area and need to find a very specific person to talk to but can’t make out their features because of the top-down view of Baldur’s Gate 3.
If you have Karlach with you, she will ask Dammon about her infernal engine and the problem of it heating up. Luckily, Dammon is knowledgeable and will be able to help her, but only if you have some Infernal Iron as raw material.
If you do have Infernal Iron with you, you can give it to Dammon, and he will solve Karlach’s immediate problem in Act 1. If you decide to massacre the Grove, Dammon will die, making completing his related quests impossible.
Act 2 Dammon Location
If you end up saving the tieflings, make your way to the Last Light Inn in Act 2. You will find him inside. If you forgot to talk to him in Act 1 and didn’t solve Karlach’s problem, this is another chance to fix her. Dammon will still need some Infernal Iron to work with, however.
If you kill the Strange Ox in Act 1, Dammon will not appear in Act 2. It’s unclear whether or not this is a bug, but keep it in mind if you’re planning on employing his services in Act 2
Act 3 Dammon Location
If Dammon survives the events of Acts 1 & 2, he can be found in the Forge of the Nine at the east end of the city. Walk inside and open the mini-map to find his location at the shop.
Where To Find Infernal Iron To Help Karlach
Infernal Iron is a special material needed to help Karlach deal with her explosive condition. During Act 1, Infernal Iron can be found in two locations:
- Blighted Village Basement. In the dilapidated building directly across from the Blighted Village fast travel point, you’ll find a basement accessible by destroying the webbing in the central room. Drop down and explore
- Goblin Camp (Dror Ragzlin’s Treasure Room). Enter the Shattered Sanctum and make your way to the throne room, where Dror Ragzlin is trying to revive a dead Mind Flayer to talk to him. At the back of this room, there is a locked door. Lockpick this door and enter to find a large treasure horde inside. Loot it, and you’ll find a piece of Infernal Iron alongside some other goodies.
Infernal Iron is not an Act 1 exclusive. You’ll be able to find more of this item in Acts 2 & 3.
