Newbie questions about magic + melee style.

Hey guys

I was wondering, what are the different kind of magic warrior builds I could try in this game? I tried looking it up on my own but there was so much stuff that I am now more confused than I was originally.

What I'd like to play is a build that would allow me to approach the game in different ways. Maybe sometimes just run in blowing shit up with magic while hacking away with swords and at other times use spells and stealth to sneak up to a target and cut its throat. Switch it up situationally. Not really that interested in min-maxing beyond not screwing up the character with bad perks/stats.

Is that kind of thing possible or would that devolve into a 'jack of all trades' character that's just average at everything and scales poorly?
