Okay so i got the game finally and like i'm lvl 10 but i'm wondering can you just become a mage type char cause i like spells the most of all in all the elders scrolls games even in morrow but like its different on here how many trees and such can you lvl cause i know i'm max pretty much alll in destruction just looking for tips

Start using Alteration, Restoration, Conjuration, and Illusion. Those are all "mage". A very overlooked thing for people who want to be a mage type, is the restoration "ward" spells. Can be awesome against dragons, as well as ranged characters. Also could look into that perk in the alteration tree that makes your spells like "ebonyflesh" give you extra armor if you aren't wearing any physical armor(just robes).

just level destruction and get the "stagger" perk and just spam 2nd fire spell as dual cast

that's all you need to do as mage

well i'm level 14 now and i got illusion level 60, destruction level 30, restoration like 25, none in alteration don't think, and conjuration is like 40 or w/e but i've only got like my perk points into destruction and restoration

Cast Muffle while you run.
