A character concept I wanted to develop is a magic-oriented character with a ninja bent. The general idea is to use magic to enchant items and always have the right tool for the right job. Weapon-wise, I would go with daggers because they are lightest weapons, so I can carry multiple enchanted daggers and always have the right tool for the right job. No armor, obviously, but plenty of enchanted clothing. Clothing is so light that I could carry around multiple outfits, depending on my needs. I think I'll be using the http://tesnexus.com/downloads/file.php?id=9914 leveling mod, so I don't have to worry about what skills I need to level for what attribute bonuses. I'm looking for opinions on the most thematically appropriate way to build this concept. Here's what I'm thinking so far.

Shinobi
Magic Specialization
Birthsign: Thief
Attributes: Intelligence (or Willpower?), Speed (or Agility?)
Skills:
Blade
Sneak
Illusion
Alchemy (for poisons)
Alteration
Destruction
Something else? Maybe Restoration or Mysticism?

That's all I have for now. I'm thinking that the last specialization should be something fitting, but also something I can control leveling. With SPAM, it doesn't matter how fast I level, but I think it does matter how soon I cap out. That is, unless one can keep developing skills after hitting their level cap.

Anyway, how would you build a ninja?

Personally I couldn't play a ninja, as I'm on the PS3/vanilla game. I gotta have my nunchucks if I'm gonna do a ninja. throwing stars, naginata, that sort of stuff. You're on the PC so you probably can have some sort of mod or whatever.

Being a ninja is not so much about character build, but what you do with those skills. I recommend using the http://www.tesnexus.com/downloads/file.php?id=8613 mod to give your character some ninja background and quests, items, etc.

Although I warn you: The enemy NPC's are likely to piss you off.
