Flee!

Although the Fifth Progenitor was infuriated by Vaan's insult, he did not rush to attack him like the Eighth Progenitor did. He had seen what Vaan could and did do to the Eighth Progenitor.

With a combination of ability and wits, Vaan played the Eighth Progenitor like a fool.

Furthermore, he even discovered a terrible weakness in [Shadow Bat Movement]. Using such a movement before a spatial-ability user was akin to asking for death.

As long as parts of one's shadow bats were sealed away, one would lose some of their fighting abilities.

Although this only reduced one's physical aspects and not one's power of laws, a reduction in combat effectiveness was still a reduction nonetheless.

Having learned from the Eighth Progenitor's mistakes, the Fifth Progenitor certainly wouldn't repeat them.
