One of the hidden items in The Forge is the Arcane Pickaxe, which is overall the best mid-to-late game mining tool. But the strong pickaxe is hidden in a secret area that you must unlock. That is where the Unknown Key helps. In this guide, learn everything about The Forge Unknown Key location and where to use it.
Where to Find The Forge Unknown Key?
The Unknown Key is obtained from the Bard’s Lost Guitar Quest in The Forge. To get it, you must talk to Bard first and start the quest. After that, go to the cave in Stonewake’s Cross and take the left to enter the undead’s chamber. You will find the Lost Guitar beside the skeleton in the chamber. Grab the guitar by holding the E key and bring it back to Bard. This will give you the Unknown Key in The Forge.
How to Use The Forge Unknown Key
Once you have the Unknown Key, you can use it to open the gate to the Fallen Angel’s Cave. The cave is located deep inside the Inner Cave. First, take the right and follow the first arrow. This will lead you to the locked gate. Once there, hold the E key to use the Unknown Key and unlock the Fallen Angel’s Cave.
If you are not familiar, Arcane is one of the strongest mining tools in terms of pickaxe progression. It helps you farm with more luck and mining speed. Moreover, it is also one of the few pickaxes in the game to have three rune slots. With The Forge quest being this simple, you can easily unlock one of the best tools in the game.
So, did you use the Unknown Key in The Forge to get the Arcane pickaxe? Let us know in the comments below.
The key is a one-time tool, so it disappears after you unlock the Fallen Angel’s Cave, which means you cannot reuse it on another run.
You cannot. The locked gate to the Fallen Angel’s Cave only responds to the Unknown Key, so the Bard’s Lost Guitar quest is required for every player who wants the Arcane Pickaxe.
