I created a fully hybrid character:a Mage, a Warrior and a Rogue. I use differing weapons depending on the situation.
Dragon:Strongest one handed weapon i have(right),Strongest destruction spell i have(left)
Human or similar beings
ual wield or shield+sword
Sneaking:Only one sword or dagger in one hand,other hand empty
Undead:Silver swords(dual wield and refined) or fire magic.
I started planning from the very beginning and raised the skills I would need while leaving the rest.Can't heal properly as a mage though, pretty much a damage dealing thicky.
