Xela could only watch on in stupefaction at Darius's deeds.
He had the most Agility of the group, at a whopping 150 points, his movement was untraceable for anyone below 100 points.
Xela herself was exactly at that level and just before meeting the Insect Lords Gunner had pushed himself to that level.
The most important thing about reaching 100 Agility was the special ability that came with it, which was Super Instinct.
It was an entry-level version of the Legendary 'Flow State' in martial arts, where one's body moved so optimally that the mind no longer needed to control the body manually.
Super Instinct was not yet there, as it only allowed one to move optimally in reaction to danger, so it only encapsulated the 'dodge' aspect of the Flow State.
