Yes, indeed, her spell was fired off inside of the gap. Just as her sword breached and Shin had bodily vaulted away from her sword's menace. It blasted out in a wide arc and struck itself against the walls of Shin's barrier and blew out the other side like a beam of electricity. A semi-tangible stream of bright blue light erupted from his barrier's porthole. In that moment, in that single moment, he realized something. Something that the both of them should have noticed from the start. Shin, with his knowledge of his own weapon, and the learned knowledge of Crystalle. For the first time since the fight had started, Shin's eye showed genuine confusion and sudden realization in two quick eye motions. 

The realization hurt more than anything so far.[color=Black][b][i]NOTHING ESCAPES THE TOUCH OF THE BLACK STAFF![/i][/b][/color] The assassin screamed to himself inside of his mind, imagine the loudest scream you can. Yeah now imagine it a thousand fold, that's about how loud he was screaming at himself.

In all their motions, Shin hadn't even noticed just how little he had utilized this ability. The staff was fully capable of deflecting objects of any property, even if they were on another plane of existence. No form of matter or energy was immune to this effect, Shin had always subconsciously avoided making contact with gaseous and fluid materials. Obviously it makes moving the staff around feel natural, he had so little use for the ability that he often forgot he even had it. It was not just a normal forgetful 'oops' either, it was something that came up so rarely that it had been shelved like a bottle of whiskey. 

An ethereal blast of energy existed on the ethereal plane, it may as well have been as hard as steel itself when it made contact. Everything on the ethereal plane was energy, and the staff can make contact with anything. Regardless of the plane of existence. The energy ricocheted off the inside of his barrier and ejected violently out the other side. Anything that it made direct contact with was incinerated, and let me tell you something. That hurts, any idiot who says that emotional pain is the greatest has clearly never felt one's soul get the equivalent of a brand. Even as he was put outside of the line of fire and out of immediate danger. Shin was lashed with what felt like a thousand whips from all directions, coupled with the busted up state of his body, this was not a happy day for Shincoco.

Aside from the fact that his offense was not only unaffected by the spell, but still in progress. Corban had even less time to escape, as well as pull her hand out of the line of fire for his Goblin Shark bite.
