Where Are The Mastery Books? Hey guys so I just made an Evan and made it to level 38. I noticed that magic guard capped at level 5, didn't pay any attention and went on ahead to put points into lightning. After a little while I noticed I was taking way too much damage so I looked at magic guard, and to my surprise, it needs a mastery book. Then I remembered that they need to be bought with NX. That's no problem, so I went into the cash shop to look, and nothing. There isn't a single mastery book in there for Evan skills. So, does anyone have any idea how or where to get the mastery books for Evan now?
