In the role-playing action game The Forge, players pick a race and follow quests to progress.
You mine rare ores, craft stronger weapons using the right ore combinations, and fight enemies.
The game has many NPCs who give quests and reward you when you complete them.
Caves are dangerous zones filled with zombies and other creatures that attack on each visit.
In this post, we explain how to use the Unknown Key in The Forge, with a clear step-by-step guide.
How to Use the Unknown Key in The Forge (Roblox)
The Unknown Key is an uncommon item you earn after completing Bard’s Quest.
Once you have the key, just follow the steps below and head to the gate.
You can unlock it using this key.
Step to Use the Unknown Key
- Go to Stonewake’s Cross, head SE to The Cave.
- Enter the cave, walk down the slope past Nord & Umut.
- Go east through zombies, turn right.
- Follow the path to the locked iron gate.
- Press E on the gate (Unknown Key auto-used from inventory).
- Enter Fallen Angel’s Cave (achievement unlocks).
Once the gate opens, walk straight ahead until you find the stone hands carved into the cave wall.
In the center, you’ll see the “Arcane Pickaxe” floating in the air.
You can purchase this pickaxe by paying “$125,000” in-game currency.
