How do I use mastery books?
So, I'm trying to use Laser Blast 20. Skill level req: level 5+
I think I failed the first time, got a message saying "The skill has gone through an uprade.", but I checked and the level was still at level 5.
Then, I try to use another mastery book, but this time it says "You can not use this mastery book."
I'm confused.. help me please. D:
