10 minutes had gone by and Group 9 was still struggling to win against the monster.

It wasn't just them too. Everyone was.

This was a monster that seemed impossible to kill.

It had 3 distinct body parts. The heads, the torso, and the tail.

Cutting off the tail would not kill the Chimera in any way at all. No animal would die simply by losing its tail. In fact, some lizards were even used to dropping off their tails on their own.

The chimera's torso was simply unapproachable too. With its hard dragon scales, not even the sharpest of swords could pierce through it. 

Finally, the heads were perhaps the only part that could hurt the chimera, but they were a separate problem too. Due to the chimera's incredible healing factor, any sizable wound was healed within seconds.
