The Abandoned Furnace Key opens a single hidden chest tucked into a blacksmithing detour in Brandrgarde. The key is a consumable that drops at random, so the hard part is not opening the chest but knowing where to walk once you finally have the key in hand and the Gyldenmist is closing in.
Quick answer: Take the Abandoned Furnace Key to Brandrgarde, leave the Drill Yard through the north gate at the top, turn right, and follow the path toward the north-eastern spawn point until you reach the small detour marked Abandoned Forge. The chest sits among the furnaces and anvils there.
Abandoned Furnace chest location in Brandrgarde
The chest is reached from the Drill Yard, along the route that heads toward the north-eastern spawn point. Getting there is a short, direct walk once you know which exit to use.
What the Abandoned Furnace chest drops
Opening the chest typically yields Epic-grade materials or Excellent-grade equipment parts. On rarer rolls it can produce Holy-grade artifacts and Camp Upgrade Materials, which makes the detour worth the extra walk when you already hold the key.
How to get the Abandoned Furnace Key
The key drops as an Unidentified Item, so any container or enemy that produces those loot rolls can hand you one. Drops run on an RNG system, and the exact next drop cannot be predicted. A few spots across Brandrgarde and Hallowgrove tend to surface keys more often than others.
| Farming spot | What to look for |
|---|---|
| Drill Yard area (Major Elites) | Corroded Major Elites near the Drill Yard have a high chance to carry Unidentified items, and keys are a common roll in this zone. |
| Drill Yard courtyard | Chests and containers hidden between the platforms around the central pit. Watch for being swarmed by enemies. |
| Hallowgrove Supreme Hall | The crucified effigies mounted on the pillars often hold Unidentified items that resolve into random keys. |
| Sunset Fjord | The Elite Berserker sharpening its axe on the southern side guards two or three lootable containers. Both the Berserker and the containers can drop keys. |
Because Unidentified Items work like a gacha layer stacked on top of RNG, some containers lean toward useful Excellent-quality-or-better rolls while others just cough up crafting materials. Expect to farm several before an Abandoned Furnace Key appears.
If you would rather skip the grind, the Auction House sells the Abandoned Furnace Key for around 300 Gyldenblod. That gives you a guaranteed route to the key without relying on drops.
Key quality and how many uses you get
Keys come in several qualities, and the quality sets how many times a key can be used before it breaks. Higher-grade keys let you open the same chest across multiple runs.
| Key quality | Uses |
|---|---|
| Sacred Key | 18 |
| Exquisite Key | 14 |
| Fine Key | 10 |
| Worn Key | 6 |
| Damaged Key | 2 |
Tip: Store keys on a high-quality keychain from the Secret Shop. A keychain lets you hold onto your keys even if you fail extraction, so a Sacred or Exquisite key is not lost the moment a run goes wrong.
With the key on hand and the route from the Drill Yard’s north gate memorized, the Abandoned Forge chest becomes a fast, repeatable stop for Epic materials and the occasional Holy-grade artifact before you head for extraction.
