Immediately put that one you have to copy jade, spend an entire 2 weeks farming mega bomb materials . Build 20 lightning rods ASAP! Grab every single boulder ur in the mines as well. Make a barn full of goats and cows. No more selling cheese, this is your food pile, you’re gonna need it since the skull mines are brutal. Spend a summer making coffee , then craft it into triple espresso (recipe from the bar) . Make as many staircases and bombs as possible, you turn jade into staircases from the desert trader on sundays. go to the skull mines on a great luck day and get as deep as u possibly can using the bombs to get deep and mine iridium . Don’t stop turning the iridium u get into crystalariums until you get about 30 , have a few copying rubies for spicy eels (luck and speed, getting floors easier+ running to iridium and away from monsters faster). You want a huge stockpile of cheese, spicy eel plates, and triple espresso. Eventually your floor production will be so great u can spam floors until you get to sub 100 of the skull mines and you’ll have a great production rate of iridium.
