Capítulo 658: Good Blade.

The only one that knows what happened during their last clash is Soverick. They are all at the zero mark and are not getting any assistance from the world during this challenge. But that doesn't make them equal. He could fight hordes of rank 4 monsters as a rank 0 and kill some of them. So he is much faster and stronger than the other competitors because of the 9 golden orbs on his back. 

Ghaster had his own advantages. His bloodline made him very fast while his instincts helped him to utilize the speed to great effect. Unfortunately for him, he is not strong enough to withstand the explosion created by their last clash. He was stunned by the explosion.
