It didn't take much time for Nil to break through to the third level. No one could see him since he was in his part of the familiar space, but he had shone beautifully as the breakthrough had his mana swirling and fur surging with a radiant shine.
Lucy has the darkness attribute, so his breakthrough wasn't as flashy as Nil's was, and while Toz had the metal attribute like Nil, he also had fire and darkness, making it slightly more chaotic than Nil's breakthrough.
Nil's shiny fur calmed down and returned to its original polished silver hue. Although it was still reflective and shone in the dazzling light of the lightning, it was a lot more matte than it had been during his breakthrough.
