Was working on some more builds, and i can’t find any information on this given the nature of them i would assume they are but would like a confirmation, that would make Sorc c1 almost a needed prerequisite for the summon familiar dark buff. which is 50% if i am not mistaken?
Want to add, yes i googled this but i don’t trust any of the information i find online, would rather someone who has a necro in the hear and now tell me whats what too much stuff is unreliable and changed 
Reread what you wrote again.
summon familiar? is the name of summon bats skill. then it don’t have dark buff.
if u mean Summon Servant? then it is not 50% it is a flat number around 50 if i’m not mistaken.
Not sure if Necro even have Dark magic but Warlock have % increased dark property attack.
Ah yeah, that was a typo. so its only a flat rate of 50? Well i was going to sorc c2 > warlock. But i was considering the idea of Sorc c1 > Necro c2 if the attacks take on dark propety. But if they don’t there really isn’t a point of taking c1 sorc
Does necro have a class attribute?
