So in the news release just now, it said under enchanting that the materials will have a component called intensity. Is this like the quality of the material? For instance, common quality, uncommon quality and rare?
Also, if they are the quality of the materials, are the quality of the materials going to be very obvious? An example being stone: common=sandstone, uncommon=granite and rare=marble. Or will the qualities be something not readily visible and detectable only by special skills?
