In Fields of Mistria, you start a new life on a farm, relying only on your cleverness and a big dream. Along the way, you’ll meet many friends and discover secrets as you explore the ruins of the mines west of town.
Every few levels in the mines, you’ll find a seal that needs to be broken. Each seal requires specific items to open. We’ll help you gather the necessary components to break the Ruins Seal on floor 80. Here’s how to quickly collect everything to move forward.
How to Create the Void Mass
After breaking the Fire Seal and descending to floor 80 in the mines, you’ll notice that the Ruins Seal is much more dangerous than the others. Once Caldarus forms physically and saves you from the sealing scroll trap, you need to go back to floor 80 to talk with the Priestess.
She will give you a new passive skill called Void Sight. This allows you to see new materials on a different plane, which you’ll need to pass the Ruins Seal. To do this, you must gather four different materials: Void Stones, Void Herbs, Void Pearls, and Void Powder. This starts the quest called Creating the Void Mass.
Gathering the Materials
- You need to collect five of each item.
Where to Find Void Stones, Herbs, Pearls, and Powder
Void Pearls can be found by fishing in waters around the mines. They look like black pearls, but more whimsical. Cast your line into the water and aim for small shadows to increase your chances of catching them.
Void Powder can be donated to the museum if you have extras.
How to Break the Ruins Seal
Once you’ve gathered all the required items, place them into the void to create the Void Mass. Using this, you’ll be able to see the list of necessary materials to break the seal. Giving these items to your Void duplicate—since you can’t interact with the altar yourself—will activate the process to open the seal.
Where to Find Firesail Fish: Catch them in the waters of the fire caverns between floors 61 and 79. Use your fishing rod and aim for larger shadows, patience helps as it might take some time.
Where to Find Obsidian: Break the black crystals around the fire caverns floors 61-79 with your sword. You’ll find obsidian in the debris after shattering the crystals.
Where to Find Smoke Moths: Look for these rare bugs in the fire caverns levels, especially between floors 75 and 79. They spawn less often, but using pheromones from your terrarium can increase the chance of attracting them.
Where to Find Breath of Flame: This plant can be gathered in the fire caverns. Search for its bright red leaves between levels 61 and 79, and make sure your inventory has enough space.
With all materials in hand, go to the altar on floor 80. Present the items to your Void duplicate; it will place the objects and break the Ruins Seal, letting you access the deeper levels of the dungeon.
