It would be a damned shame if Shin could watch her every movement and see what she was doing as it was happening. It would be a shame if Shin didn't notice how much probing she had been doing. It would be a shame if Shin could intentionally sever the connection between parts of the Black Staff. 

Sure would be a shame if all of those were factors in this battle.

It was also a shame that the battle was about to come to a sudden and jarring close. 

A literal close as she had, in her overconfidence, put herself in the middle of his death trap. Right in the middle of around twenty feet of spikes and blunt tendrils as they were closing in on her. She had one thing right, her spell would have totally disrupt The Black Staff. Had it had made contact with it. As she swooped into her dive, as her blade was thrust towards his barrier, Shin opened a hole before her. Allowing her blade to pass through the bulk of his construct and towards himself.  Like a camera's rolling shutter, it rotated open as her weapon came down.

Why? 

Isn't it obvious? She had put too much faith in her ability that she didn't realize she was trapping herself. No matter how fast her movemnts were, she had willfully thrust her weapon arm forwards to shatter his own weapon. She had done a number on him, yes. Broken a few ribs, his right arm was gone and his face had been fractured by the weight of his mask slamming into it. His right leg had a hairline fracture, and he had actually been stabbed by a shard of rock from her concussive blast. But she hadn't dismembered him, she hadn't broken every limb, she hadn't killed him.

And that was enough.

Shin was prepared for her stab, that's why he was prepared to move. Shin vaulted backwards, using the nearby spear as a springboard. Shin raised the entirety of his body upwards with a sharp backwards leap, pulling his center of mass up like a pole vaulter in reverse. Her blade passed harmlessly beneath his body as he vaulted away, but he wasn't nearly done with her. He extended the makeshift arm to push himself further away from the body of his weapon. All in one fluid and catastrophic motion his devious machinations unfolded.

[color=black][i]She didn't notice the similarities?[/i][/color] Shin thought to himself.

The Hydra's the bastard child of an Iron Maiden and a Bear Trap, as her weapon passed through the barrier. As Shin gave the illusion of his Staff collapsing from her spell, her stab would continue forward. Why? Because she put too much speed behind it. The staff would snap forward and downwards like the jaws of a Goblin Shark. Right around the arm that she extended with the blade. Hopefully, though not a certainty, to repay the arm that she had taken away from him.

But that's not all. Remember that he was closing it around her anyway? Remember that he had raised it upwards so it could spear her as she moved away? No? 

Shin raised the backside up to strike at her before, and she had countered with her defense of myriad blades. The entire bulk of the entity had not simply stopped moving, and this was her great folly. She had thrown herself at great speed into the center of it. The rear end had already been raised, the barrier that he had raised between himself and her was brought up to create a pseudo jaw shape. The size of her blade and her own body made this whole contraption the perfect size for ensnaring and spearing  a human sized body. The remaining bulk of the contraption would snap shut around her like a bear trap, consuming and impaling her from all sides. 

But Shin had one more weapon to ensure that she wasn't going anywhere.

Corban had even eliminated her own escape route by not cutting it off. It was still overhead. Shin didn't rid himself of the claw, and so too had it a purpose in his incredibly convoluted plan. The claw was the roof of his three pronged prison. It dropped its weight on top of the entire construct.

As he vaulted away and held himself aloft with the extended makeshift arm, he sneered behind his mask. Shin had even put himself outside of harm's way just in case she managed to escape his devastating plot.
