The Rider's Fall
Reign knew that the rider's desperation was an opportunity for them, that without the darkness that the rider had summoned, he would be vulnerable. The manifested claws of darkness were powerful and fierce, but they were being used recklessly and desperately, not to mention that they were being used by someone who was still not used to his powers.
The claws, although dangerous, were manifested in a hurry, and thus they were not as powerful as they could have been. The rider was doing his best to use them to their fullest, blocking attacks and attacking back with them, but even that proved to be highly difficult thanks to Reign and his constant interference.
