ST: Material Macgyver

Material Macgyver	When you’re involved in any kind of crafting process, you know how to make what you need with whatever is on hand. While you are involved with the crafting process, you reduce the gold cost of crafting by 50% and can allow for substitute materials of the same calibur (not any metal metal, but substituting Mithril instead of Dawnsilver if you have both) as long as 10% of the bulk of the item is made of the necessary material. This stacks with other features and talents like this multiplicatively. This also applies to costs that go into making Log Books.
Prerequisites Proficiency with Spellcraft, Tinker, or any Profession skill.
