Quinn had been in many battles and he had experienced a large number of different abilities. He had even fought against Sil who had the ability to recreate some of the strongest powers in the world.
He had fought against celestials with their strange energy and had experienced the power of Mundus, the messenger of the gods, with his power of time. Yet this power from Immortui, the ability to make the world and the area colourless, was something he had never experienced before.
The power not only affected his attacks, but affected the energy from within, including the energy that was in his own body. He could feel it being eaten away, and it had even affected his shadow powers.
The shadow, the god slayer ability that was able to protect him so many times, worked against even Mundus with his power of time, yet the energy from his own shadow that was meant to block out everything was being drained.
