DD, can you cite someplace where it says Ares is immune to non-magical attacks?  If that's the case so be it, but I have never read his abilities as such.  In the Classic Marvel TSR game he like all Olympians got a good degree of resistance to energy and physical attacks, but they weren't immune to normal damage.<br/><br/>As far as Ms Marvel goes, she's been described as one of the most durable beings on Marvel Earth.  It takes a lot to hurt her in the comics.
