*Note: You don't have to do it in order from 1 to 7, you can start to do it with any of your choices. The Arkhium Stock will automatically form after only you collect all 7 of the Mysterious Ores. I'm highly recommend you do this because the rewards are huge.
You will need 7 Mysterious Ores in order to make Arkhium Stock.
