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 on it and if we will see it be used in later volumes. Also what spells would you want him to learn?
