Steel ore

Steel ore can be mined outside the gates of Tokaji, but you can only mine them if you have at least did part of Keiichi's Trial in Ak-Haranu's Students, otherwise, it will say: "You don't know if you want to mine this particular rock unless accompanied by a mentor.". It takes a long time to mine, but can be put directly into a furnace to receive an Eastern steel plate. You need level 75 Mining to mine this ore. In order to make Regular Steel Bars too, you have to do part of Spirit of Lu Bu quest.
