So I just reinstalled the game a week ago, and have finally gotten to level 27 and a castle. I am now ready to dive into the collecting portion of the game. Can anyone explain when the items for collections appear? Is it only with certain level chests and up? Or random? I have opened maybe 10-15 common to rare chests and all are tools or xp. Also, I too am always short on iron. Seems to be too rare in the mine, and over demanded in crafting an hiring.
