"Fireball!"
After getting close to one of the lizards from its left side, Eren cast his fire-element spell using both of his hands separately. He then jumped high using his movement spell and released both of the fireballs onto the beast's torso.
Eren then executed his movement spell again and tried to create a safe distance from the beast he had just attacked. And to his surprise, he found that he could easily be able to do so.
'What the fuck? These huge-ass lizards are slowpokes as fuck!'
Eren turned back and saw the lizards still maintaining the speed they had approached him with. The beast he had attacked also seemed fine. He even looked a bit faster than the rest as he had started to lead the other two.
