Transmutation Expertise

When you cast Transmute, you can target multiple basic objects, as long as they fit within the space, to combine them into a more complex item. As long as you provide the basic objects required, as determined by common sense or your GM, and you have seen or have some sort of reference to go off of, you can create almost any complex object you like. For example, with a bar of steel, some leather, and some wood, you could Transmute them together into a sword.
