It's been so long since I read this that I decided to start over from the first chapter. The author must have been thinking "haha big number funny" but it's far into the realm of nonsensical even for fantasy. The stat scaling would have to be logarithmic to an insane degree but then that would be a shitty world design. Like would you play a game that told you you needed 1,000,000,000,000,000 strength to double your damage dealt? Then to double it again you'd need a billion times the previous amount? I would call the author stupid.
