The local Mining Grounds are a hot spot for resource gatherers and collectors alike. You'll find all sorts of crafting materials out there: wood, dirt, stone, Pure Slimes, and may even run into a treasure chest or two. But it's important that we also keep our own greedy nature in check! You take what you mine. If you don't have enough space for it, tough luck -- there's a penalty fee you'll have to pay. Best of luck out there!
Roll a die and try to fit in the material corresponding to the number you rolled. Put the material in your backpack or if you don't want to, discard it and take away some points for later. Your backpack has a limited space. If you run out of space you will have to discard that item and pay a fee.
