Whats with the lack of expert Mage knowledge? Eh... I think i'm just going to do what I said I would do before unless a high leveled Mage wishes to enlighten me with his/her build.
It's all about your playstyle. SPR if you wanna see more big burst damage and you like the color purple filling out your screen. INT for constant, steady, reliable damage.
My builds 1:2 INT:SPR. You want to have a good amount of INT to increase your damage. We naturally do alot of damage, but hey.. might as well have LOTS of it ^^
