unless im just a total noob, i dont think im missing any other base-game monster fighting & mining areas... (aside from the quarry but like shhhh)
anyways, the titles pretty self-enclosed !! of the 3 mining & combat areas, which one is ur favorite ? (^人^) i think mine has to be the skull caverns-- theyre a pain in the ass at first, but once u get better equipment i think its SO much fun to just dive down as far as u can
