Quick Answer
The Mines have five biomes beginning at floors 1, 20, 40, 60, and 80. The current 1.0 reference maps them to Copper, Iron, Silver, Gold, and Mistril ore respectively. Deeper progression is gated by the seal questline, ending at floor 100.
Key Information
- The five listed mine biomes are Upper Mines (1-19), Tide Caverns (20-39), Deep Earth (40-59), Lava Caves (60-79), and Ancient Ruins (80-100).
- The guide associates each biome with progressively stronger ore and a distinct gem/forage/artifact set.
- The seal questline is reported to unlock deeper areas in water, earth, fire, ruins, then final-seal order.
- Official 1.0 notes added dungeon quests and dungeon rewards; v1.0.1 also fixed several mine-related crashes.
Details
The Fields of Mistria mines are a progression system as well as an ore source. A player should enter with a clear objective: find a seal item, gather a specific ore, complete a dungeon quest, or collect artifacts. The current 1.0 fan guide divides the mine into five twenty-floor biomes. It lists Copper Ore at the Upper Mines, then Iron, Silver, Gold, and Mistril in deeper regions.
The seal questline matters more than raw floor count. The community guide describes a sequence of water, earth, fire, ruins, and a final seal at floor 100. Use that as a route-planning framework, but provide a separate verified requirements table before publishing item-by-item instructions. Official 1.0 notes confirm additional dungeon quests and rewards, and the patch history confirms that mine stability has received fixes.
For a practical guide, recommend taking enough recovery items, managing inventory, upgrading gear for the current biome, and banking rare materials before a risky descent. Avoid publishing enemy weakness charts unless they are current-data verified.
