There is one thing that you did not mentioned and that is the Illuminate Mind talent. I am not sure at what what level it will bring a stripped down Maria (with no staff, runes, or saints) magic attack over 10,000. I am maxed out (level 99) and it is +15130. The setup that you specified is dependent on the Illuminated Mind level that you have and will not work for every one. You will have to face a dilemma as you move up. Keep Illuminated Mind down so she can heal every one, or continue to bring it up so that the other Mages hit harder. Look up though this tread and you will see that all of this, including the 10,000 Magic Attack, has already been discussed.
