Class Ascept

Fighting an opponent that could just disappear was definitely something to be afraid of. Who knows? He might be seconds away from peircing his heart.

Guilliman put his guard up immediately, what followed was a barrage of punches that instantly broke his jaw Causing him to bleed from his nose.

"Fuck!!" Guilliman cursed, raising his hand to guard against the incoming attacks, but how could he guard against something he couldn't see?

Boom

Boom

Booom

He kept getting struck from all sides, but he maintained his composure, quickly thinking.

Class Ascepts, he knew about these, it was an ability granted to Slayers after they cross the threshold of Blue and chose a class.

For people with predetermined bloodlines, it was much easier to initiate the class ritual while others had to actively find a way to go through it just like Guilliman.
