Using Shadow overload in a situation like this seemed quite crazy but Quinn had his plans. He didn't know how long Bryce or Arthur had been fighting for, but both of them were physically wounded and not at their best. There wouldn't be a better situation to subdue the two of them then at this moment now. Quinn needed to finish it.
With Arthur unable to use his shadow due to the strange crystal, Quinn thought he would have a nice surprise for them both.
[Shadow overload activated]
The shadows started to pour out from Quinn and soon covered his body giving him the shadow body he would usually get. He was waiting to see if his shadow body would be consumed by the crystal but it didn't seem to be the case.
Then, letting out a slight flicker of Shadow control, Quinn could see it heading for the crystal. Although the shadows on his body weren't influenced by the crystal, whatever he would use would be.
