I have playing ACB and accidentally sold 1 shrunken head found in treasure. It seems there are only 2 shruken heads available in treasure chests in the game. So the only other way to get back a shruken head is to invest in RGE system. But the process is painstakingly slow!!! I can only invest 1000Florins at a time for every twenty minutes in a single shop.
I am expected to make 1million F's. Which is really hard...any suggestions or hints how to invest and reach the target amount quickly? I have currently 400,000 F's.
