Capítulo 250: Killing Calamity Mutants Like Crazy

Thud!

A head fell to the ground, and Karsha quickly grabbed the Core, brimming with pure fire energy. After killing his first Calamity Mutant and uncovering the secret of their Cores, he started hunting more of them. 

Regardless of their Tier, a Calamity Mutant's Core is unique compared to most monsters. According to the system, a Calamity Mutant can potentially ascend to become a World Boss once they reach Tier 9. Though it's not a sure thing, there's still a chance.

The process is incredibly tough and demanding. Once a monster becomes a Calamity Mutant, usually around Tier 7, its Core starts storing elemental energy. 

This energy is crucial for advancing to the World Boss stage. However, the journey is so difficult that most monsters stop at the Terror Mutant stage.

Still, the Tier 8 stage is a pivotal point. It's where a monster decides if it wants to pursue the World Boss class.
