I just want to be able to make my own wands. The gem could determine the type of wand and the "other" material could determine the charges. If you take a wooden stick from a broke door and put a fire gem on it you could get a wand of fire with one charge. But if you have say an eternium ingot and a wand of knowledge it should give you a wand with magic map or identify or something else pertaining to knowledge with lots of charges in it. Im sure theres all kinds of raw materials to be found that could be used in wand creation.
