Might not be to your taste but if you really need restoration leveled you just need Equilibrium in one hand and Healing in the other and some patience.
Takes to long and it means I have to do the college questline early on. My above method is pretty quick, pickpocket training up to level 51, then use close wounds with the mage stone at High Hrothgar, in the ice wind. Use as many fortify restoration enchantments as you can find.
I have a similar build to this, more of a shadow ranger then a "theif". Since you are picking alchemy perks and are an assassin, id suggest picking the poisoned perk. Some think its useless but I found it very useful for silent kills. Also you can paralyze people and steal their gold, even when it say 0%. Free training, lol.
Yeah I haven't used this perk before, sounds quite useful, I'll give it a go considering I have the previous perks anyway.
Do you know which perks are affected by necromage as a vamp, and do all of them have to be taken after you have both the necromage perk and vampirism to be affected?
These need to be taken while you have the necromage perk and are a vampire.
The ones I can confirm are: Hypnotic Gaze, Aspect of terror, Rage, Extra pockets, Augmented flames (not the others it seems).
But I imagine quite a few more do, I'm sure the damage perks (armsman for example) are boosted, also the dual flurry perks I think. I also think kindred mage and animage are affected but I haven't tested it, it's a little difficult to test it on xbox.
Marked for Death and Aura Whisper in my opinion. Aura Whsper to detect enemies, Marked for Death then disappear to get the enemy low.
I'd say become ethereal, it allows you to be invincible for a few seconds (boosted by necromage) it's great combined with power attacks mid combat.
