Henry noted a couple of things in the five seconds he waited for Nyx to get back from however far she had run to;
The first note was the fact that the activation of the <Shadow Dash> skill was completely without his input.
Of course, the more Henry thought of this, the more it made sense. He had never told Nyx how to run. The most he had done was urge her to go faster or go slower depending on need so why should that change just because she had evolved into a Magical Beast?
The second thing Henry noted, was that he had not received a notification from the system about how much Mana the <Shadow Dash> skill had cost.
Nyx returned and she was breathing slightly harder than normal. Her legs did not shake from fatigue and there was no other sign that she was tired physically, and yet her breathing was labored.
"How far did you run?" Henry asked as he patted her neck.
