Caius casually swung down the flame coated sword toward Orun who is coming at him from above.
The sword on its way down, had its flame amplified, and the further down it goes, the rapid its intensity and its area of effect magnified.
Orun was not confident enough in changing his path in time before the flamed sword gets to him. .
He is currently in midair, jumping down above Caius. It would require extra movements from Orun if he wanted to change what direction he is going to be falling at.
Caius is just as fast, if not faster than Orun is. The time it would take for Orun to change his path, is more than enough time for Caius to follow through, and also change the direction his great sword is going to be heading to.
Well aware of the indisputable fact, Orun made a choice of not evading the great sword, but instead taking the full grunt of it head on.
