In the midst of the intense battle, Eren had devised a daring plan to take down the relentless GrayScale Fire Wyvern.
Knowing that using Sedating Gaze on the dragonkind would likely fail, he cleverly used the failed attempt to his advantage. By momentarily slowing down the wyvern's reactions, Eren seized the opportunity to climb over its massive back and launch a deadly attack from close range. The beast's compromised responses prevented it from effectively countering Eren's swift assault.
However, the failed spiritual attack had its consequences. Eren endured physical and mental backlash, which hindered his ability to utilize many of his spells and abilities. To compensate for the restrictions imposed by the space-element runes, Eren had to think creatively and adapt his battle strategy.
