My ideas: Zombie starts out with no armor or weapons and it pretty much svcks. Then, you could level up in Conjuration and get like 100 'Magic Points' and open up a menu in which you could spend those points for maybe a Steel Cuirass or a Steel Longsword. Or if you prefer to have your zombie just go nvde and hand to hand then you could upgrade attributes like Strength or Endurance and just a CRAZY idea..... Maybe the zombie could be a wizard? Shoot Paralysis spells or any Destruction magic.
I wanna hear your ideas! Post them!
