Water

Wain raised his sword as he directed most of his energy toward it. Even if the monster was seriously wounded, Wain didn't believe it was enough to end such a powerful creature, so he needed a last resort.

Tremble. Tremble. Tremble.

The darkness turned into a massive torrent of energy that reached the heavens. The eerie jaws in the darkness made even the eyes floating in the river among the bones wary.

"Come on, don't make me look stupid. One attack certainly wasn't enough to beat you, was it?" Wain said with a calm look while letting massive waves of aura out.

Whoooooooosh.

Suddenly the water rippled as if from an earthquake, then a silhouette flew out of the river from which a dark liquid quickly flowed.

"Huh, you made it out of there, after all, that's what I expected." Wain smirked before he collapsed the sword with all the energy that he had accumulated.
