'Ora' wasn't really repulsed, in a sense.
It was literally in everything.
Humans.
Air.
Nature.
Even most dead things had a similitude of 'Ora' connected to them.
Thus, even when chaos repulsed matter, it didn't 'negate' it.
More than that, Liam's chaos had never disrupted his own spells and techniques.
Sure, it repulsed and weakened them to a degree, as seen with Liam's Black Blade and chaos combination.
But it had never utterly distorted them.
Liam didn't think it was even possible.
But he was proven wrong.
No matter how hard Liam tried to conjure up a darkness spell, it failed to leave his body.
Mental attacks still worked fine.
They were immaterial, after all.
But everything else was a no go.
Liam gulped heavily.
Didn't this mean the Black Hole was rendered useless?
And by extension, his Void?
…But so was everyone else's!
