The Key Forge belongs to the Impossible Island. Here, you can forge Keys that are used to open Impossible Mines. Forging a Bronze Key (the first key you can forge) takes 5 days of real-time or you can melt Boosts to reduce the forging time. When a Boost is melted, it cannot be used again.
Once you have collected enough Keys, you can use them to unlock the next Mine on the Impossible Island.
Types of Keys & Forging Times
- Bronze Key: 5 days
- Silver Key: 10 days
- Gold Key: 15 days
Melt Boosts to forge Keys faster!
