Without the presence of the Dragon protege hunting together with him, Emery had essentially lost a very capable frontliner and thus needed to find a new strategy to hunt the horde of Shrikes.

"This creature is tough to kill!"
The moment Emery encountered a pack of the Legendary beasts, he would immediately summon an army of Jade Warriors and command them to bar them from reaching him. That way, he was free to do as he pleased, killing the creature one by one while at the same time staying out of harm's way.
But still, although the Dragon protege's role could be replaced by the Jade Warriors, the latter was simply incomparable to the former. Without Zach's help, the speed of killing and devouring the scorpion creatures fell down by a huge margin.
