What Is the Abandoned Furnace Key in Mistfall Hunter?

The Abandoned Furnace Key in Mistfall Hunter is a chest key that unlocks a hidden loot chest inside the Brandrgarde map. Like all keys in the game, it drops as an Unidentified Item, meaning you will not always know what you have until you identify it. The key exists in multiple quality tiers – Damaged, Worn, Fine, Exquisite, and Sacred – and each tier affects how many uses the key has before it is spent.

Finding a chest in Mistfall Hunter is only half the challenge. You also need the matching key to open it, and you need to know exactly where to go before the Gyldenmist closes in on you. This guide covers both – where to farm the key and exactly where to use it in Brandrgarde. If you are also working on other key hunts, our guide on the Demigod Coast Key in Mistfall Hunter and the Verdant Grounds Key in Mistfall Hunter cover the other major locked chests in the game.

Where to Use the Abandoned Furnace Key – Chest Location

The Abandoned Furnace chest is located on the path leading from the Drill Yard toward the north-eastern spawning point of Brandrgarde. This is in the northern part of the map, and it is easy to miss if you do not know what you are looking for.

Step-by-Step Directions to the Chest

Head to the Drill Yard point of interest in Brandrgarde.
Exit through the north gate (the top entrance of the Drill Yard).
Turn right and follow the path leading northeast.
After a short distance, you will see a small detour area labeled the Abandoned Forge.
The area is recognizable by the old furnaces, anvils, and scattered blacksmithing tools left behind.
Search among the forge equipment to find the chest hidden inside the area.

The chest is not in a locked room – it sits in an open area within the forge, but it blends in with the environment. Take a moment to sweep the area carefully rather than rushing through it. Time is always against you in Brandrgarde, so make sure you have the key on you before you head toward the Drill Yard.

Key Quality Tiers and Uses

Keys in Mistfall Hunter are not all equal. Each quality tier controls how many times you can use the key before it wears out. Here is a breakdown of all key tiers:

Sacred Key – 18 uses
Exquisite Key – 14 uses
Fine Key – 10 uses
Worn Key – 6 uses
Damaged Key – 2 uses

If you are farming the Abandoned Furnace chest regularly, aim for an Exquisite or Sacred key so you get more value per run. Damaged keys are not worth the trip if you are making a dedicated detour for this chest.

One important tip: always store your keys in a Pip’s Keychain, which you can purchase from the Secret Shop. The keychain keeps keys safe even if you fail your extraction and die in the field. Losing a high-quality key because you forgot to store it is one of the most avoidable mistakes in the game.

What Loot Does the Abandoned Furnace Chest Drop?

Opening the Abandoned Furnace chest can reward a solid range of loot. Here is what you can expect:

Epic-grade materials – the most common reward type
Excellent-grade equipment parts – useful for gearing up or selling
Holy-grade artifacts – rare but possible, making the chest very much worth farming
Camp Upgrade Materials – also drop on rare occasions, which makes this chest a nice bonus stop during Brandrgarde runs

The loot is RNG-based, so you will not always get the best rolls. But the combination of Epic and Excellent grade items as baseline rewards makes this a worthwhile stop whenever you have the key on hand.

How to Get the Abandoned Furnace Key

The Abandoned Furnace Key drops as an Unidentified Item from various sources across Brandrgarde and Hallowgrove. The game uses an RNG system, so you cannot guarantee a drop from any single source. That said, some locations have a noticeably higher chance of producing keys than others.

Best Spots to Farm the Abandoned Furnace Key

Here are the most reliable farming locations based on community reports:

Major Elites near the Drill Yard: Corroded Major Elite enemies in this area have a high chance of dropping Unidentified Items, and keys appear frequently among the rolls. This is the single best spot for targeting the Abandoned Furnace Key specifically, since it is right next to the chest location.
Drill Yard Courtyard Chests: Around the central pit, there are several chests and containers hidden among the platforms. Both the containers and any enemies guarding them can drop Unidentified Items. Just be careful – the area tends to have a lot of enemies and you can get swarmed if you are not paying attention.
Hallowgrove Supreme Hall: The crucified effigies mounted around the pillars of the Supreme Hall often contain Unidentified Items. Most of them end up being random keys, so looting them regularly gives you a decent shot at the Abandoned Furnace Key over time.
Sunset Fjord Area: Look for the Elite Berserker sharpening its axe on the southern side of this point of interest. He is often guarding two or three chests nearby. Both the Elite and the containers can drop Unidentified Items that can roll into keys.

Buy It from the Auction House

If you do not want to rely on RNG, you can simply purchase the Abandoned Furnace Key from the Auction House for around 300 Gyldenblood. This is a reasonable price if you already have the Gyldenblood to spare and want to guarantee a run to the chest without farming first. The Auction House is run by Pip at Windrest camp. To find him, check our guide on where the Secret Shop is in Mistfall Hunter.

Tips for Getting the Most Out of the Abandoned Furnace Chest

Plan your route before the run. The chest is a detour off the main path through Drill Yard. Know exactly where you are going so you do not waste time wandering in a dangerous zone.
Clear the Drill Yard Elites first. If you farm a key from the Major Elites near Drill Yard, you can immediately use it on the chest without backtracking at all. It is the most efficient way to handle this in a single run.
Bring a Pip’s Keychain. Do not carry a high-quality key without protection. If you die before reaching the chest, you lose the key unless it is stored safely.
Do not over-stay. Once you have looted the chest, move on. Lingering in a high-value area invites PvP attention from other teams. Loot fast and head toward extraction.
Use higher-tier keys on this chest. Save your Sacred or Exquisite keys for repeat visits so you get more uses out of them rather than burning through Damaged keys one by one.

If you need help with your extraction after looting, read our guide on how to extract in Mistfall Hunter so you always get your loot out safely.

How the Unidentified Item System Works for Keys

All keys in Mistfall Hunter drop as Unidentified Items. This is essentially a gacha layer on top of the normal RNG drop system. Some containers and enemies have a higher probability of producing Excellent Quality or better Unidentified Items, while others are more random. This is why certain farming spots feel more productive than others – it is not just about drop rate, it is also about the quality tier of the Unidentified Items those enemies tend to carry.

When you identify an item and it turns out to be a key, always check which key type it is and what zone it belongs to before planning your run. Using the wrong key on the wrong chest does nothing, and you lose a use of the key in the process.

Other Keys and Locked Chests Worth Knowing

The Abandoned Furnace Key is just one of many locked chests across Brandrgarde and Hallowgrove. If you are planning a loot-heavy run, it helps to know the other chest locations too so you can chain multiple opens in a single session. Check out our related guides:

Is the Abandoned Furnace Chest Worth It?

Yes, especially if you find the key as a natural part of your Drill Yard farming loop. The chest sits right on the exit path and costs you only a small detour. The potential for Holy-grade artifacts on top of reliable Epic and Excellent materials makes it a strong value stop. If you have to buy the key from the Auction House at around 300 Gyldenblood, it is worth it as long as you are committed to actually using it in the same run.
