Good idea, I like it! Just as long as it doesen't resemble those star shaped, cute fairy-wands, eww. It should rather be a sturdy wooden rod, that pulses with magic and epicness and stuff.

And it shouldn't replace the sword, it could be like ocarina or the wind waker, a necessary and useful tool, but not really created for battle. The rod could even have offensive spells, but they aren't really designed to everyday combat, maybe they suck too much magic force, have a long cooldown time or something.
