Hey everybody! It's Firestar here and I have something that might help in the mining in HMDS. This is also an easy way to earn money.
First Step: Go to main room where alll the mines meet
Second Step: Equip your hoe and if you have a truth bangle, equip that
Third Step: Save your game
Fourth Step: Mine with your hoe until you find something you like
Fifth Step: Remember the spot where you found it and reload your save game
Sixth Step: Go to the spot you found what you wanted and mine that spot
Seventh Step: Save Game and repeat
Final result: New item that's worth a lot of G, saved stamina for more mining, and saved time
If you have stressed all the items and you still have a lot of stamina, exit the cave and re-enter and do the same thing you did for the previous mine.
