How to Unlock Mines Ancient Ruins Biome in Fields of Mistria

The scope of adventure in Fields of Mistria continues to widen with its continued updates to the game, and the Fourth Major Update (0.15.0) brought an abundance of new content for players to enjoy. Whether you prefer the casual farm life with focus on things like Apiaries and Terrariums, or you’re the more adventurous type that likes to explore all the mysteries that Mistria has to offer, this update brings a little bit for everyone.

Perhaps one of the biggest pieces of that update is the continuation of the Mines questline, allowing you to reach the furthest depths at long last. However, as expected, getting access is no easy task. Here’s how to complete the quests to create the Void Mass and break the Ruins Seal in Fields of Mistria.

Feeding dozens of animals a day is no easy task. Time to make it easier!

How to Create the Void Mass in Fields of Mistria

The game’s Fourth Major Update (0.15.0) introduces the final biome of the Mines as the Ancient Ruins (Floors 81-99). However, just as you did with the Fire Seal in the previous section of the Mines, you’ll first need to fulfill some objectives to reach the ruins themselves.

This time around, as you’re dealing with some serious magic at these depths, there’s an extra step involved. After speaking with the Priestess and helping her open a portal thanks to your Dragon’s Breath ability, you’ll be able to step into it and emerge within a celestial plane that she deems “one step closer to the Magic Realm”. However, you can’t access the Ruins Seal just yet to see what’s required to break it.

To gain that access, you first need to gather four Void materials from within the Mines to create the Void Mass. To help you see and gather those materials, the Priestess grants you a new ability called Void Sight. It’s a passive one, so you don’t need to worry about constantly activating it.

Below are the Void materials you need to collect while traversing the Mines. They include Void Herbs, Void Pearls, Void Stones, and Void Powder. You need to gather five of each material.

You can find them on any set of floors, so you can stick to earlier ones to make it easier if you wish. Make sure you have all your fundamental gathering tools with you, and submit any extras you get to the Museum.

Void Herbs

Void Herbs resemble a dark purple plant with three leaves, and you can gather them just like any other plant in the overworld or Mines.

Void Pearls

Void Pearls are gathered by reeling in small fish (look for small shadows!) in any of the ponds or streams you find in the Mines. These have a high drop rate, so you’ll likely stack these up first.

Void Stones

Void Stones resemble a large, dark purple gemstone with a brighter outline around it. Break it apart with your Pickaxe to gather stones from it.

Void Powder

Void Powder can spawn as a rare reward for defeating various monsters throughout the Mines. While drop rates vary for every player, these can arguably take the longest to obtain.

Once you’ve gathered all the necessary Void materials, return to Floor 80 and head back inside the portal. Approach the cauldron at the top of the steps and interact with it to place the Void materials into it. Select ‘Offer’ and the Void Mass will then manifest above the cauldron, the initial task completed.

Next, the Priestess will use the Void Mass to create a decoy of your persona, which is needed to interact safely with the Ruins Seal tablet. Once done, you’ll be able to decipher the materials required to break the seal. They include a Breath of Flame, a Smoke Moth, a Firesail Fish, and a piece of Obsidian. This time, you only need one of each.

Breath of Flame

The Breath of Flame is a red plant you can forage in the Lava Caves section of the Mines (Floor 61-79).

Smoke Moth

The Smoke Moth is also found in the Lava Caves section of the Mines (Floor 61-79), but it can take some time to spawn as it’s an Uncommon-tier bug. They’re notable by the smoke plumes they emit over their heads.

Firesail Fish

Firesail Fish can be caught in the Lava Caves section of the Mines (Floor 61-79). Watch for large fish shadows in the ponds, as these are the ones that can yield this particular fish. It may take some time for them to spawn, so this will likely be one of the last items you obtain.

Obsidian

Obsidian can be gathered from the black crystals that spawn in the Lava Caves section of the Mines (Floor 61-79), and/or by defeating Lava Cat monsters. However, if you have the Stone Refinery unlocked, you can also craft it from regular Stone. This can save you a lot of time exploring.

Once you have all four materials collected, return to Floor 80 and approach your decoy. Give them the requested materials and the Ruins Seal will then be broken at last. With that, you can now enter the Ancient Ruins section of the Mines. Beware, though, that the floors ahead are shrouded in darkness, and traversal will be all the more challenging. Best of luck!
