Reward Pool Mission (7)

Noa carefully crept toward Glen and didn't dare to be careless even more a second. When she appeared in front of a dimly lit chamber, she saw the silhouette of the man walking back and forward. 

Without hesitation, she moved toward the final layer between her Glen!

Noa very carefully entered Glen's chamber when he was walking with his back facing her. She knew she had to be very careful with her timing of entering because needs to exit the Serene Assassin state before she could use her storage ring and talisman. 

This was probably the biggest flaw of this ridiculous ability, yet it was not at the same time because an assassin like her only needed a single moment to make quick work of her target.
