I've raised my mage in earth magic to 13 so I have the all useful poison shield, but beyond that earth is not really worth it...
Now I want to raise a second school of magic to be it's main attack one... and I'm doubting between Air and Fire. Air seems to be the most useful, and there are no enemies with resistance to it... but fire has all the nice equipment and allows you to protect the party from those nasty Uugardians...
What do you guys think?
