Hi! I've had my own
experiences with my mage.
First, I should inform you that quickness-based Mages are terribly inefficient at splatting; it's usually only a good idea to invest points in extra quickness if you intend to spend a large amount of your time on Larkinor island or running trips for monstology.
Second, I should also inform you that most mana-draining monsters are going to be unbeatable for at least the first level you find them regardless of how much you invest in int.
With those in mind, and if you're deadset on an int or quick-based mage, I'd highly recommend you put a few more points into Persistence; I like the number 100! After that, you can keep Intelligence at a fairly high number and still invest plenty of points into quickness.
P.S. You can't edit posts here, once you post it's there forever :p
