The damage caused Mason to struggle more than before as it tried to get out of its current situation.
The other leg waved around more as it struggled, as if in pain and desperate to escape.
Just as it was in that state, Ash had already finished chanting and gathered energy of her own.
She continued to condense it further as she added more to it until it reached a stage that would be more difficult to control.
She could feel herself reaching her limitations in how much Life Energy she could hold onto, so she stopped adding more to it.
The ball of Life Energy was then sent out toward her target after positioning herself, resulting in the ball flying toward the back of Mason.
The exposed back was left open, and Ash was able to land an accurate hit in the middle of it, very close to the spine.
The grade of Ash was not completely known to her, but the damage done by her blast was no less than what Laura had achieved.
