I am thinking of doing this on my character, but I read in the wiki that it has been fixed. Can anyone confirm?
You read wrong
Also, does it work with perks if I have necromage before I select the perk?
Some perks, magic resistance, atronach, dual flurry(x1.35 becomes x1.69), Quick Draw, recovery, avoid death and a few others.
It won't effect damage related perks or crafting
