Thanks for the quick answer, mvenom-san!....

So It is time to continue main story line without care much about it until unlock some dungeons such as Labyrinth of the Ancients and so... About the tomes of phil and myth, I obtained a few of phil in Stone Vigil and the dungeon with weird name lvl 44. (Dzmael something)... So after that I'll obtain in roulette tomes? because can't remember if I obtained a few in the roulette of that day, I think not.

Regards.
