I really like this build, well done! 

Hey Zaxton.  I just finished this series, and I fell in love with the Night Angel pretty quickly, and I'm glad to see someone made a build based off of it.  There were a few things I wanted to say about it.  I'm definitely not a build expert, but for magic absorption, you could try the ultimate atronach trick, and not need to be a breton for it to work. *SPOILERS BEYOND* And if you wanted to mimic the Ka'kari's ability to cover the Night Angel entirely, you could try to use the Ebony Mail, for its shadow cloak thing.  *EVEN MORE SERIOUS SPOILERS* Finally, on a role play note, whenever the Night Angel dies, he comes back, but someone else has to die because of it.  So maybe whenever you die in the game, you have to kill someone who likes you in the game, to represent that.  But all that said and done, this is an awesome build, and you definitely get a +1 from me.

This was a really good build. One thing I would do is add a section on alchemy. Show what kind of potions and poisons you use and what ingredients to use. Other than that awesome build
