On the way, Karsha transferred the avatar of the snake to Kilian. The shieldbearer was already stronger and more destructive; he didn't need another powerful avatar stealing his thunder. What he needed was someone who could create an advantage for him. With the mist skill of the avatar, Kilian could trap enemies inside the mist, giving him all the time in the world to power up his skills and techniques, unleashing earth-shattering attacks on the trapped opponents.
He figured the avatars would be more useful in the hands of his shadow guards, allowing them to showcase their strength even more.
