Harvest Moon: Friends of Mineral Town Tips

The Mythic Stone
The mythic stone is a stone that you can use to upgrade your tool into. You can get one at floors 60, 102, 123, 152, 155, 171, 190, 202, and 222 of the Spring mine beside the waterfall. When you get it, upgrade it in Saibara's shop and you will have a so strong tool. If you don't want to upgrade tools, you can sell this stone for 50,000 gold.
