Most of Nial's senses were unaffected by the huge box's effect. It only influenced his dark energy and the mana around him, which was already more than enough for Nial to feel a heavy pressure weighing down on him.
'Good thing that I trained moving and fighting without my mana perception since I had my lovely encounter with the inability to sense mana in the Fairy Queen's territory,' Nial thought, the corners of his lips curling upward.
His mana perception had been the replacement of his eyes. However, now that his second pair of eyes had disappeared as well, he was back at the starting point. Of course, his other senses were extremely sensible and he was able to control his Vengeance of Chaos ability as he had accumulated bits of Chaos inside his body. The accumulated crimson moonlight was not affected by the mana distortion effect of the huge box either.
