As much as everyone wanted to ask if they had heard Walker right, they all knew that he was not joking or messing with him in any way. It was very clear that he had already used the all around appraisal skil.
When Walker had called even more fire balls and started to attack the blood kin bats, it caused a chain reaction. The other forces nearby had begun to attack as well.
Worse off yet, the bats had begun to make loud and sharp pitched sounds. Everyone knew that this was just how bats could see. They made sounds that would somehow make an image for them to see in their heads. Echolocation. It was a common fact when people who lived anywhere near forests or caves would see bats and learn about them.
The different elemental attacks that went in to the air causing many of the blood kin bats to fall were also being disrupted by the sound attacks. They vibrated the air and even snuffed out one or two of Walker's fire attacks.
