Billy succeeded, but he didn't learn any skills. It was probably because the effects were too weak… Still, if some mana needed to be seen in order to take effect, it seemed like a problem. Billy didn't want to make his kids stand out by shining. Regardless, the amulet didn't make him shine either, so he will probably find an answer eventually. The hard path was over, so he just had to endure it for a bit longer.
"Come to think of it, Fierce Blast is a mix of mana and stamina, but even while it leaves my body, the energy still can work…" Billy thought. "It must be because of the nature of the skill."
It was really weird. The mana could do a lot as long as there was a connection between Billy and the final use of the energy… And that was a problem since Billy couldn't stay with his kids all the time. One step at a time… With that mentality, Billy continued with his training.
You have learned Mana Shield.
