Item Crafting
When you provide a piece of Infernal Iron to Dammon in the Last Light Inn, he will forge the following pieces of armor (in order):
- Flawed Helldusk Armor
- Flawed Helldusk Helmet
- Flawed Helldusk Gloves
Repair Karlach’s Infernal Engine
Infernal Iron is necessary to repair Karlach’s Infernal engine (The Hellion’s Heart).
Visit the Emerald Grove and speak to Dammon with Karlach in your party. Give him the Infernal Iron to repair the engine. This saves her temporarily until you meet again at Baldur’s Gate.
Warning: if you raid the Emerald Grove, you will lose the option to speak to Dammon and cannot repair Karlach’s engine.
