for a full mage you get full use of the three points in magic skills at the start (as explained in the magic tab, and i can try to clarify if needed). A "battle mage" would initially be limited to one or two points depending on the depth of their training (more focused on magic get 2 points, more focused on weapons one 1 point). So for your character you could be a Sorcerer in said element.

Sorry made an edit to the magic section after thinking about it and put the new rules and such there. but for a full mage you can have 4 points at the start instead of 3 :)
