Umbra's surprise attack worked partially because the Air chanter panther's hind leg had been pierced, preventing it from using its most powerful trait.
It's horrifyingly high speed!
With that in mind, Shane could distance himself a little from the battle that was about to happen.
It wouldn't be the smartest move if he were to attack a peak-Awakened stage beast whose forte was its agility and lightning-fast reflexes.
On the other hand, Shane's speed was at most comparable to that of a low-Awakened stage beast and that was after he utilized every little trick that he could pull out!
As such, Umbra had to fight against the Air chanter Panther alone, which was something Shane didn't like to see!
Their strength was at par with each other, but Umbra's affinity was higher in rank than the panther's. It allowed him to utilize the advantage he had over the injured panther, forcing it to retreat.
