I am working on learning crafting, and so far I have only used the special material types for Blacksmith & Tailoring (Copper, Bronze, Gold, Barbed, Spined, etc.) to fill BoDs. I understand from the uo guide wiki that these special materials have additional properties that are applied to the item upon creation. I guess my dumb newbie question is, what is the use for these materials aside form filling BoDs? I can create a leather suit using Spined Leather to get additional Luck stats, but can't I just craft it with normal leather and use Reforging / Imbuing to add the specific stats that I want, such as Luck or other properties? Why use these special materials when I can get what I want with other means?
