'Now it's time for me to test the only fire-element insight I haven't used in battle yet.'
Eren thought to himself and snapped his fingers as he was getting a one-sided beating from the restless wraiths. When he lay down on his back, being kicked, pierced, and maimed without getting any injuries, he saw a fireball with a radius of about a meter being created.
The creation of the fireball was taking place right in front of Eren's eyes as he was looking at the sky. The wraiths that were beating him had realized by now that there was some time bomb being created over their heads. So they paused and looked at it collectively.
The fireball soon stabilized. But instead of attacking anyone, it kept hovering in the air. Then it started shrinking as it released a conflicting mana pulse.
"Screeeeeee!"
The wraiths tried to use their sound attack on the fireball. As if to answer their call to battle, the fireball started growing multiple fire snakes from its outer surface.
