An Assassin?

Who would have thought there were more Evolution paths for Beasts?

'I did think about it, but just didn't pay attention to it,' Nox thought as he read the book. It was true he had indeed thought about this several times in the past, but because of the training in preparation for the upcoming tournament, he didn't think much about it.

According to the book, Magical Beasts had only three final evolution paths with extremely high requirements to reach. After completing the first evolution path, there would be another, which would be even more difficult.

This cycle would go on until the beast reached the Sovereign Tier.

The first requirements and materials were already difficult to obtain; what about the other two?
