"I have to leave this place immediately!" When Shen heard the notification, he immediately decided to leave instead of continuing watching the battle between the bosses. He would die from watching the battle between the two bosses.
He would lose 25 Hp per 5 seconds, and he only had 440 Hp. That meant he would die within a minute and a half if he stayed in the range of the frozen breath. Moreover, this was just the start of the battle. The Ice Vulture Boss would launch a stronger frozen breath later, and he would die even faster if that happened. On top of all that, his movement was slowed down by sixty percent. If somehow he survived after the battle was over, and the boss noticed him. He would die for sure with his slowed-down movement.
