Choosing Job and Evolution Requirements[2]
[Ace POV],
To begin with, all jobs in the common grade are removed from the list. As long as nothing is wrong with my brain, I will never choose a common job over the jobs above it.
There must be a reason why the jobs have grades to begin with. It could be because one job is more special and powerful than the other. So, as long as I have a rational mind, I'm not going to choose jobs in the common grade.
Something I've noticed about all of the jobs listed on the panel is that they are all related to me in some way. Perhaps this is what the Primordial Chronicle meant by my records.
When the end of the old world arrived, the first weapons I used were the DMX-367 DOUBLE BARREL SHOTGUN and the Normal Grade Hunter Recurve Bow and Quiver. Perhaps this is why jobs involving archers and guns became available.
