The Demon Bathin

David fought off the monster in hand to hand combat, each blow of theirs could have killed any regular man, or even a mage filled with arcane defenses. 

Whenever the Prince struck the beast, it was filled with such heat that it exploded numerous times over. If it were not for their power of regression, their whole body would have been scattered into the cosmos.

Whenever the monster would strike him, they would try to revert him back to dust; however, because of the state David was in, where he was essentially constantly accelerating himself, this was not so easy, only barely slowing him down.

Each one of their blows shook the air, sea, and land, causing massive shockwaves that reverberated throughout the island, their sheer might reshaping the earth around them.

It was a miracle that everyone around was even somewhat alive, but it wouldn't be that way for much longer if the monster had anything to say about it, and he had much to say.
