User blog:PsychoWolf101/Dark Wisdom

I wanted to start this cause it's been bugging for a while. From what I have gathered Ainz dark wisdom can increase his spell list by making a sacrifice but I have also read that he can learn spells from corpses of those he has killed though I believe it's only spells that the killed person knew, And if that is the case then isn't it potentially possible for him to learn every spell. I would like hear everyone's thoughts on the matter, and their opinions.
