Fields of Mistria Mines Guide — Floors, Ores & Magic

The mines are Fields of Mistria's mid-game money engine and the source of its magic system. They unlock at Town Rank Stone, and from there they gate almost everything: tool upgrades (ore), the museum gem sets, magic spells, and the voidite questline that runs through the endgame.

This guide covers unlocking, the floor structure, what to keep, and how magic actually works. For the money side of the farm game, see the beginner's guide.

Unlocking the Mines

• The mines open when you reach Town Rank Stone — the fastest route is museum donations + shipping + requests (see the beginner's guide for the renown plan).
• The mine entrance is northeast of town; the bridge repair turn-in is the direct prerequisite quest.
• Bring the Copper Pickaxe — the stamina difference versus the starter pick is huge.

Floor Structure and Biomes

The mine is a multi-biome dungeon that changes character as you descend:

• Upper floors: copper, common ores, basic monsters — the early-game training ground
• Mid floors: iron and better ores, gem nodes (Ruby, Emerald), and treasure chests appear roughly every third floor
• Deep floors: the four biome areas (community-documented) shift enemy types and ore tables; rare gems and voidite spawn here
• The mine lake: deeper levels contain fishable water — including a legendary fish (see the fishing guide)

What to Keep (and What to Sell)

• Keep: Copper and Iron for tool upgrades and the forge; any gem you haven't donated to the museum (see the museum guide).
• Sell: excess gems and low-tier ore once your tool upgrades are done.
• Never sell: voidite and void items — they're quest-critical for the deep-mine seals.

Magic: Tablets, Seals, and the Statue

• The Statue of Caldarus (your farm + one in the mines) spends Essence on perks and magic skills.
• Essence drops from monsters, golems, and mining — the same resource feeds both the mining/combat tree and the fishing/farming perks.
• Spells unlock via tablet quests found in the mines (the Water Tablet is around floor 20). Spells share a mana pool that recharges slowly, or instantly with mana potions.
• Elemental seals block deep-mine progression until you complete the associated tablet quests and gather the required items.

The Floor Plan: Biomes and Depths

The mines are divided into sections, each with its own ore table, monsters and collectibles (the rare items guide maps items to floors):

• Upper Mines — the early floors around the entrance; copper, common ores, the Stone Loach fishing spot, and the Water Tablet quest around floor 20 that unlocks the first spells.
• Tide Caverns — roughly floors 21-39; the ocean-themed section with Jade Dulse and the mine-lake fishing pool.
• Deep Earth — floor 41 and deeper; dig spots, rare gems and the Faceted Rock Gem artifact; voidite and the deep-mine seal content live at the bottom.
• The mine lake — fishable water deeper in, including a legendary fish and treasure boxes you can pull up with the fishing rod.

The elevator carries you between unlocked floors, so progress isn't linear — unlock the next section, then farm your favorite level. Treasure chests appear roughly every third floor in the mid-levels (per the main guide) and are the best money per stamina.

FAQ
