you can craft it IF you have the racial mats.
Yes. Each race (style) has a stone or metal or whatever specific to it.Are Style materials required for blacksmithing?
You can usually buy these from vendors, but they can also be found, and can be obtained by deconstructing items from that same style. They are not "mined" anywhere though. Note that you also need knowledge of the style to craft it, which is obtained through lore books you find at random in chests and boxes or whatever.Also, how are these found?
