The Mines inFields of Mistriaare vast and have many items and artifacts to collect. However, after descending multiple floors into the mines, you will face multiple breakable seals blocking the next sections, halting your progress. Certain items are required to break these seals, which are different for every seal in the mine.
On Floor 40, progressing 20 floors after the first seal in the mines, The Water Seal, is the second and more time-demanding seal: The Earth Seal. To cross this seal, you will need four items found in the same mine biome, but they require a tremendous amount of grinding through a certain biome.

How To Break The Earth Seal
According to Juniper’s Translation, breaking the Earth Seal to venture further deep into the mines requiresfour things.
After successfully collecting the required items,head back to floor 40of the mines andplace them on the Claw Pillarsnear the Earth Seal. This willbreak the Earth Seal, and you will be able to descend further in the mines until floor 60. Below, we detail the four items and how to get them.
