Dagruel dispersed Nihilistic Hazard and Tempest Meteor

Shortly after the battle started, they had a brief strategic meet with Adalman who just returned.
As they can't count on their advantage in numbers, they decided to probe the enemy for information by making use of the Immortal Legion's undead property.
It was a conservative move, but for the sake of discerning the enemy's capabilities, they reached the consensus of avoiding a full scale clash at the very beginning.
In addition, there was a point of concern that Gadra spoke of.

「I found it to be a little perplexing, how did they disperse the “Nihilistic Hazard”....?
To me, it looked as though they were nullifying the magic――」

That was what he said.
As he has spent all his Energy and was unable to cast another volley of Great Magic, it was his intuition as a Great Magic User that gave him the feeling that something was amiss.
The meteor attacks also didn't cause as much damage as was expected, but it was how unnaturally his “Nihilistic Hazard” was dispersed that really gave rise to his suspicions.
It might just be him imagining things, but it's better to take note of this.
It's not like Shion could use magic, but attacks that made use of energy could be affected too. It was expected to at least be wary in case it really happens.
