How do I get tons of stone quickly? I’ve been playing this game for a couple of days and have really been enjoying it. Its Winter and i decided to farm stone so i could build stairs to get to level 300 in Skull Cavern and farm iridium. So far its been really slow farming stone, and Robin sells it for 100 gold a piece which is way too much. Any tips or tricks? (P.S. I play on iPhone)
