It was safe to assume that this dungeon break would be classified as the most dangerous in history, and those who hear of it will say the same thing: I'm glad I was not there. However, for those present, it was hell.
Amelio grinned as he punched, the veins on his face bulging as if they were about to explode. The strength released from his stats was transferred to the world, appearing as a giant magical circle. As he saw this site, Arthur knew that was happening.
"A seal."
This calamity has sealed himself in order to survive the split. That was the only method for him to be counted as a calamity that can exist here, instead of being sealed like the guardians and the calamities. It might also explain why his mana stat was like that.
As the punch was directed in his way, Arthur received the full-on attack of the anomaly. However, the runes in front of him made sure that most of that strength would be reflected backward, like a ping-pong ball.
Boom!
