Lake Mine (Story of Seasons: Friends of Mineral Town)

The Winter mine can be found in the center of the lake within the Northern Forest. This mine can only be accessed either during Winter when the lake has frozen over or once the player has obtained the [Teleport Stone], unlike the Spring Mine, which can be accessed all year round.

Special Items
A variety of special items, such as collectibles and recipes, can be found within the Spring Mine

Cursed Tools
Once the player has upgraded at least two tools to level 5 (mythril), Cursed Tools will become available within the Winter mine. These tools are only found when tilling on specific floors. These tools have a low spawn rate and are not guaranteed to spawn at all. They player may need to save on the previous floor in order to allow them to "reload" the tool's floor in the event that the tool does not spawn.

Kappa Jewels
There are a total of nine Kappa Jewels found on specific floors within the Winter mine. Once all are collected, the player will receive the Goddess Gem which is a tool that can be used to relieve fatigue.

Kappa Jewels can be found on floors: 0, 40, 60, 80, 120, 140, 160, 180, and 255

Floor Nine Pond
On floor nine there is a cave entrance that leads to an underground pond. The Coelacanth [King Fish] can be fished for here.
