Sword of Death and Destruction
"Aaargh!!" A howl of pain and agony echoed throughout the icy cave as tremors passed through the ground upon a huge monstrous body hitting the ground with five severed necks.
With just two combined attacks, Damien was able to cleave through five of Yohr's necks for a total of six heads, including the neck, where he had two heads!
When the jet black lightning bolt struck Yohr, it pushed him into the jet black vortex of lightning behind, which collapsed after sucking in all six of his heads and cleanly severing them from his body.
That was the amount of destructive power it possessed!
Yohr's body was even tougher than just his ethereal cultivation, and Kalypso had accounted this as a factor when she told the approximate level of strength Yohr had now after getting weakened by Luna.
