10th Floor, Luna Winterbell

10th Floor, the ultimate challenge for Paragon-rank powerhouses. 

To pass this floor and reach the peak of Arena Tower, a Paragon-rank powerhouse must fight against a Chaotic Beast of Unbound-rank in the 3rd stage.

Facing Aleron in this challenge was a Four-armed Hammer Ape, an early-stage Unbound-rank chaotic beast.

Pure statistic-wise, this monster was stronger than Aleron. It would take truly powerful skills to consume at least 500 Chakra energy to even breach the natural defense of this Unbound-rank Hammer Ape. It was twenty meters tall and its four arms were metallic giant-like hammers and its body was also metallic silver with gray and black patterns, with four fangs out of its mouth and four eyes, giving it a savage appearance.

But Unbound-rank chaotic beasts had a fatal weakness that could allow Paragon-rank powerhouses to kill them.

Their Lifeform catalyst, called Unbound core.
