The Mines are a staple feature of any classic farm sim RPG and are typically brimming with slimes to battle and valuable resources to discover. The Mines are an explorable area in NPC Studio's Field of Mistria, but you won't be able to visit them straight away. It turns out the Mines were closed for safety reasons after the town earthquake, and NPC Errol needs a bit of persuading to re-open them, especially when he claims he can hear strange noises from within. As a result, you'll need to do a bit of groundwork to unlock the Mines in Fields of Mistria as an adventurer helping to restore the earthquake-shaken town in various ways.
