Navigating the sprawling streets of the Lower City in Baldur's Gate 3 eventually brings players to unique locations brimming with hidden gear and specialized companions. The Forge of the Nine serves as a vital blacksmithing hub that players must locate to progress specific companion storylines and secure high-tier equipment. Understanding how to find this workshop and navigate its associated tasks ensures your party remains well-equipped for the final battles.

Finding the Blacksmith in the Lower City

The Forge of the Nine is located in the eastern portion of the Lower City map, situated just north of the Basilisk Gate Waypoint. Players can easily spot the building by looking for the open-air forge area where the tiefling blacksmith Dammon works diligently on his latest creations. If Dammon survived the events of the previous acts, he will welcome you warmly and offer his services as both a merchant and a master craftsman.

Reaching this location early in Act 3 provides an excellent opportunity to sell accumulated loot and upgrade your frontline fighters with sturdy gear. The shop is easily accessible from the main street, meaning your party can return here frequently between major excursions into the city's dangerous dungeons.

Completing the Hellion's Heart Companion Quest

For many players, visiting this specific smithy is essential for advancing Karlach's personal companion quest line. If you have gathered additional Infernal Iron during your travels through the Shadow-Cursed Lands, Dammon can use his specialized knowledge to patch up Karlach's unstable infernal engine. This crucial maintenance provides her with temporary stability and unlocks deeper narrative choices for her relationship with the player.

Failing to visit the blacksmith before progressing too far into the main campaign can lock out certain outcomes for Karlach's story arc. Making the trek to the eastern district should be treated as a top priority as soon as your party gains access to the Lower City proper.

Securing Premium Infernal Armor and Equipment

Beyond his role in companion quests, Dammon stands out as one of the premier gear vendors available in the final act of the game. Players who bring him rare components can commission the crafting of the Flawed Helldusk armor set, which offers excellent defensive bonuses and fire resistance properties. He also sells a variety of enchanted weapons and shields that can complete specialized character builds for your companions.

Investing your gold into his inventory ensures your martial characters can withstand the high elemental damage dealt by late-game bosses. Be sure to check his stock after long rests, as certain base materials and general supplies may occasionally refresh.

Navigating Potential Complications and Bugs

Because the blacksmith's presence depends heavily on choices made during the first two acts, players should verify his status upon arriving at the location. If the tiefling refugees did not survive the previous zones, the shop will be occupied by a different vendor or left entirely abandoned. Additionally, ensuring that local street fights or guards do not aggro near the shop boundaries prevents Dammon from prematurely fleeing the area.

If you notice any unexpected behavior from the merchant npc, try reloading an earlier save or resting at camp to reset the local environment layout. Keeping this critical vendor safe ensures you maintain access to his excellent blacksmithing services throughout the entirety of Act 3.
