Don't mean to sound newbish, but what's necromage? Why are VL's so better with it than normal ppl? what does it do? And how do I get it?
A vampire is undead.
Necromage is a level 70 restoration perk that makes all your spells more powerful against undead.
And the PC is undead.
So anything the game considers a spell cast on the PC gets a flat-out boost.
This includes worn enchantments, shouts, potions, summon duration, some perks, blessings, a lot.
The downside of getting 70 restoration and vampirism early in the game is that you have a lot of weaknesses.
I enjoy these weaknesses and play around them but at higher levels its also possible to counter them with enchantments or potions.
