boys, boys. let a master explain this okay? * cough cough * yeah right. [img]tongue.gif[/img]
1. choose breton because of the obvious boost stat they give to your magic skill. it will save you lots of headache. besides, female breton is beautiful to look at you know?
2. go for atronach. it will give you 2.5 x magicka. don't worry about stunted magicka. just take alchemy as major skill and keep on producing restore magicka potion ( which can be produce a lot in the game ). new idea no?
3. Alchemy, destruction, restoration, illusion, alteration, Mysticism are good choices. that will leave you 4 more skill to choose for your combat ( weapon skills etc etc ). I assume you don't choose any thief skill.
also, remember to patch up your game. you can thus gain multiplier from misc skill as well.
my experience as battlemage? okay, it sounds very exciting at first. but later in the game you'll notice you will use your weapon most instaed of your magic. which give you this thought, " why the heck did I play this character? "
