I suppose that could work, if you feel you can handle it, feel free to go for it... :D Although most characters will possess some measure of unusual abilities, some will fufill more stereotypically "mage roles" than others.
Your character is only allowed one main special weapon to start with, although some of the 10 items they might chose to keep could be weapons. It would be appreciated if you described briefly what it does and looks like, though it is by no mean mandatory. Most weapons in the world are special in some way or other. You may have other side weapons as part of your starter items as well.
