Interesting idea, I think I get what your aiming at a mage that runs all over and touches his targets for spell effects, thats it right?
No have not tried any touch spells at all, that is exactly the opposite of what I do with my mages, I do however max out Intel and SPeed and COn but I try to keep her as far from the sharp end as possible.
I would be afraid of being caught in the middle of a melee without any action points after using spells and approaching to lethal range.
Could be a slice. I dont know, but it is interesting, very contrary to what is usually thought of mages.
