i have another question, how to get a steel pickaxe.
i cant craft the steelbar or mithirlbar because i cant find one.
Steel pickaxes are produced in the blacksmith near calbridge stronghold. It works the same way as with any other resource on the overview map, you need the building and all required materials, then it'll automatically be produced. Keep in mind that it is also automacitally consumed for further production that require it. So maybe you already produced some steel pickaxes, but they were used for something else by the time you checked your storage.
