Depends.
If you need health potions, I'd suggest the alchemy skill (or talent), meteor-strike is quite good, too (I call it "the machine-gun of all spells" <img src="/ubbthreads/images/graemlins/delight.gif" alt="" /> )
Just two suggestions.
There is somewhere a link to Kaans (or Caans ?) Mage Guide, look for it by using the Search funtion.
