Will Nexon put DB skill books in CS?

Here are the prices if you're wondering:

 Spoiler

There's 6 mastery books total, 1 brown (2nd Job), 1 green (2nd+), 2 red (3rd+), and 2 black (4th). I'm not familiar with which book is for which skill, but for comparison purposes, Karma Scissors are 2.7k NX in kMS (but Platinum Karma scissors are 5.4k NX), and you can buy a 10k kMS NX code for 11 USD from a website.

Of course, they could reduce or increase the number of mastery books, change the prices, but this should give you a fairly good idea of how much the packages cost.
