Will Nexon put DB skill books in CS?

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.

2nd Job skills consist of only Mastery, Booster and Triple Stab. To give any of these mastery guides would be the dumbest move in gaming HISTORY.

2nd+: Slash Storm
3rd: Tornado Spin
3rd+: Flying Assaulter, Mirror Imaging

Are you sure there's a 4th? o.O

Additional Information! The mastery guides dropped by monsters have a 50% success rate, while those in the CS have a 100% success rate!
