Gravis was really surprised about the assassin's willingness to hand over his Avatar. While Gravis held the daggers, the assassin had no connection to his Avatar anymore, making him nearly helpless. If Gravis summoned these daggers into his Spirit Space, the Avatar would be overwhelmed by Gravis' Spirit.
This meant that Gravis could destroy the Avatar with a mere thought.
There was absolutely no way to recover from that.
"Why did you hand over your Avatar?" Gravis asked.
"Because I can't win," the assassin said helplessly. "I'm only good at assassinations, not in a direct conflict. All my Laws and powers revolve around assassination. Any Immortal King on my level can easily kill me in a direct confrontation."
Gravis frowned as he scratched his chin. "Then how did your Will-Aura become so powerful?" Gravis asked.
