So, what is you digging skill? Do you use the hammer and dig rashly, or the pickaxe and dig carefully? And then,are you usually successful in unearthing everything, or does the wall crumble before you even manage to dig something? Apart from spheres, what are the items that you usually get? And what are your other experiences that you get from digging?
As for me, I usually use the pickaxe and dig in one of the 2x2 square, because an item's size is (if I'm not mistaken) more than 2x2. So far I've obtained one Hard Stone, a Max Revive, some shards, and once a Heart Scale. What are other rare items that you find? And how do you ensure that you can dig everything just before the wall crumbles? Do you just get plain lucky, or do you plan your digging carefully? Tell your stories here~
