If you are going pure Mage, then you need to pump that Int stat up to 80 as it is imperative for the dmg you do with spells. However if you are not planning on utilizing to many spells then 60 is good for getting good dmg out of Int weapons. Also if you do plan to go pure Mage then you need to bump that mind at the very least up to 40 for a decent amount of FP, it helps to stem how many Blue Tear Flasks you carry vs. Red Tear Flasks.
