As he was rocketed towards Arthur Adrian coalesced every bit of hell matter he could around his body in an orb. It was literally a bubble that enveloped his entire body and turned him into a human(demon) wrecking ball as he flew towards Arthur at enormous speeds. As Arthurs sword hit the ball it would bury into it, but not enough to cause fatal damage to Adrian. The sword rose and cut into him above his left hip leaving a mild wound that was instantly cauterized by the hell matter's heat., but didn't go past the bone thanks to the resistance of the Hell matter. The huge ball of burning energy would continue to fly towards Arthur at enormous speed all the while.
