Best build archmage

Hello guys.
what is the best build for archmage ,both master of heavens and master of life?
Beside i want to know which stat point will give critical damage ?well some classess like shadow warrior and witch hunter have critical damage but i dont know which state point will give it to use it foe other clasess.

I put most of my points in focus for damage, the rest I split fairly evenly between wounds and accuracy, with a few in leadership for extra energy, though to be fair I have managed thus far just using a potion or eating something when my mana is low.

something here example 120 focus 50 accuracy 40 leadership 40 wounds

ooh wow. pls do tell how you come up with 120 50 40 40 stats when the total doesnt add up?
