Instead of evading, Gravis simply waited until the crocodile came closer.
'Twice, already,' he thought. 'I could have killed you again with a Lightning Crescent just now. You can't even distract me properly,' he thought with frustration.
The crocodile was not using its most effective weapon against Gravis, which would be its element. By shooting some compressed water beams or some icicles at him, he would be forced to defend himself or evade. Sadly, the crocodile only charged at him to bite him.
Yet, the crocodile couldn't be faulted for this line of thinking. It was a Divine Beast, and it was two levels higher than Gravis. Theoretically, its body should be around 32 times more powerful than Gravis' body. Therefore, in its mind, its body would be the most powerful weapon against him.
