I have 2 character builds that I have used and enjoyed...
The first I did was a Breton... Vladenov... I maxed out the perk trees for Conjuration, Illusion, Restoration, Sneak and One Handed Weapons... and got a few invested in Light Armor and Archery.
The Second I did was an Orc... Gurag Smash-Smith... I Maxed out the Two-Handed (Hammer), Heavy Armor, Smithing, Enchanting and Archery, I have a few perks invested in Sneak and Restoration.
My first character is the perfect assassin... my second is a one man army... both are a lot of fun depending on how you like to play.
I'm thinking of creating a new character and mixing the two, maybe smithing, enchanting, sneak, illusion conjuration and one handed...
