why do you go down both the right and left side of illusion? Kindered mage overides them i think as it works accross the board and if not you can duel cast so that makes up the difference there's 3 points back right there.
It doesn't override. They stack. I always fill up that tree.
spread out your Alchemy more, refunding 1 point.
I agree with that.
take assasians blade out as its not needed and is rather OP, by all means take it back you still have 5 extra points.

By having the appearance of being an Assassin type char/vamp. Assassin's Blade is not a waste by ant means. I would keep that. The idea is to one shot the enemy anyway. If that fails, you are detected and the hits go from being deadly to being a bee sting.
the below build is where id put them in speech for you. i have also gone up to 51 as ''necromage'' from resto applies to you as a vampire so all enchants etc are increased by a great percentage.

Of course one is to do as they see fit with their character. Although I still fail to see how spending valuable perks in Speech grants the rewards over the cost. There is an unlimited supply of gold in the game. After you get your house, spells and gear, those perks become obsolete. I would rather invest perks in something that would benefit my character for the entire game.
EDIT : So far none of my Vamps have used Destruction, or any character for the matter. Still, taking the Necromage perk is an idea that I would entertain if I was planing to forego a Destruction Vamp. It would still be very viable for one anyway. I have just ended up putting them somewhere else, for one reason or another. One day I will do the Necromage, no doubt.
