Ash mumbles to herself. "Various methods start to become less effective toward them as the gap becomes much wider too so even if I want to continue this current course of action, I cannot possibly go around hunting Spirits like I usually have once I start going after higher grades of Spirits."
Ash had started to recognize that her current approach of hunting Spirits and her methods to obtain more power would have its limitations one day.
Her method would only work on certain grades of Spirits and she would soon reach the point where she would be unable to use that same method against anything higher.
The only option left for her was to continue her Spirit hunting activities on lower grade Spirits that it still was effective on but as she progressed further, her requirements needed to rise higher would become much greater and perhaps her progress would become much slower.
