The raid within the Boss Room proceeded quite smoothly ever since Gentle Wind and Autumn Breeze were assigned the task of waking up the distorted Tanks.
Due to the large numbers on the raid, Xu Feng could afford to have three players doing another task whereas the rest continued to focus on dealing with the other Elite Enemies.
Although there were times when players got hit with petrification, the Clerics were quick on their feet, using the water acquired from the Cracked Fountains that were scattered across the 10 passages to cleanse their status.
Since petrification was considered a category curse type, the waters in the Cracked Fountain could cleanse through it. This was also hinted quite earlier on during the system prompt message when they entered.
Thus, Xu Feng had the others to gather all the waters available in their respective Cracked Fountain precisely for this moment.
