It would be a complete lie if Emery said his body was not trembling in fear when he saw the fierce battle happening in the distance. The horror in his eyes grew exponentially when he saw the normal expressions in the two Wind Wolf warriors, who had turned into frozen sculptures, proving they didn't even realize they had died until the very last moment of their life.
"That's a tier 7 spell. That must be it. There's no other explanation otherwise," said Emery to himself, eyes still fixed on the scene of magnificent destruction in front of him.
The fear Emery experienced was justified though, as he was currently only able to cast up to tier 4 spells. Even if he managed to make a breakthrough to rank 9 right at this instant, it would only allow him to cast tier 5 spells. He clearly saw how Beatrice didn't leave unscathed when she tried to counteract it with her tier 6 spell.
This matter was clearly out of his league, just like what Klea had told him before.
