Hey all...
I want to return to oblivion and really do something different. When I was younger I only did woodelf archers. I want a new character after my newly found love for them in skyrim... A dunmer spellsword. I want him to use fire and a sword and light armor everything else is up in the air so I want to see what the community thinks the best build/birth sign would be best, so what do you guys think? Help a brotha out?

Well, you probably want to start with a Dunmer...

...So, you'll probably need one of the three birthsigns that boost magicka, since you don't get a racial boost. Since you're building a hybrid, and will be using weapons and armor, you won't need a vast magicka pool. I'd suggest the Mage as a birthsign, and supplement it a bit by taking Willpower and Intelligence as favored attributes.

The other possibility, if you don't mind micro-managing magicka, is to go with Atronach birthsign, and Intelligence and Strength (or Endurance) as favored attributes (never take Willpower as an attribute if you have the Atronach sign.)

...And you already know that you want Blade, Light Armor, and Destruction as major skills. Other usual choices for a Spellsword type would be Restoration and Block. Then pick a couple of other slow-leveling skills to fill out the list.
