Hey guys I need some help with this one, any suggestions to skills is appreciated. Here what I was thinking:

Race: Altmer or Dunmer
Class: MagiBlade (I'm hoping to get absorb health or magicka on the blade
Description: Uses alteration to shield himself, then uses sneak and invisibility _{(has this been confirmed as a spell yet?)} to get close and strike with a poisoned blade. After weakening the enemy he attacks with destruction magic, moving in a out of the enemies attack range, using invisibility if needed to gain distance/maneuver behind the enemy for dual casting, then a blade once his magic is depleted.
Against multiple targets he would weed them out with frenzy and/or calm/fear spells. If he is discovered before the initial strike is possible, he would use destruction to weaken the enemy, then a blade if needed.

SNEAK: Stealth(2), Backstab(1) = 3
ILLUSION: Novice(1), Dual Casting(1), Animage(1), Kindred Mage(1), Gaze(1), Terror(1), Rage(1), Quiet Casting(1), Master of Mind(1), Apprentice(1), Adept(1), Expert(1), Master(1) = 13
DESTRUCTION: Novice(1), Dual Casting(1), Apprentice(1), Augmented Flame(1)/Frost(1)/Shock(1), Deep Freeze(1), Disintegrate(1), Impact(1), Adept(1), Expert(1) = 11
ALTERATION: Novice(1), Dual Casting(1), Apprentice(1), Mage Armor(3), Adept(1), Stability(1) = 8
ONE-HANDED: Armsman(3), Bladesman(2) = 5
ENCHANTMENT: Enchanter(2), Soul Squeezer(1), Soul Siphon(1), Insightful Enchanter(1) = 4
ALCHEMY: Alchemist(2), Physician(1), Poisoner(1), Benefactor(1), Concentrated Poison(1) = 6

If I can get past 50 I will work on getting extra effect in enchanter.

Do I need anything else? Do you think any of these skills are superfluous?

Invisibility confirmed i think (Illusion spell)

Sounds like a decent stealth-mage to me atleast.

Would resoration maybe be better than alchemy? Remember restoration has a +50% magicka regen perk (I think its 2 ranks 25/50)

Alchemy could be great aswell though. More mana for other spells so you use other resources for healing.
