The kobold twins, Valda and Alex had already known that Ethan would be starting the fight with a fireball explosion since they had also used it a couple of times on their own on a smaller scale to prevent a forest fire from happening. However, the scenery in front of them is certainly something that they had never seen before.
A wall that was fully made up of fire was standing tall in front of them. The height of the wall is about a head taller than themselves, and the heat that was emitted by the fire wall was even felt by them even though they were now standing about 10 meters away from the fire wall.
They had been waiting from about 25 meters away from the group of deer from 2 complete opposite directions at first before Ethan launched his attack, but after they heard the deafening boom, instead of getting surprised, they started dashing towards the group of deer.
