Btw, since they haven't really explained it yet: the "Out of 600 points" talk is referring to the stat limit for players currently. 100 is the cap for each stat, 6 stats = 600 points total. The higher the stat the more of a difference there is in them. The difference in strength between someone with 95 strength vs 96 strength is a whole lot more significant than someone with 70 strength vs 71 strength. (This isn't a spoiler, it all got explained in the first few chapters of the LN)
