"Stay calm everyone. Continue to do damage and the boss will come back down eventually. Azure, when that happens, I want you to be in the very centre of the fight, ready to draw aggro." Lu Li was very calm because all they had to do was to dodge the fire raining upon them.
Lu Li decided not to tell him that the Boss would land right on top of him.
There was less and less space for the players to manoeuvre around as the fire continued falling down from above. Many players were burned to death.
However, Lu Li had taken all of this into consideration; it was impossible for everyone to survive this stage. As long as more than two-thirds of the party survived, they would have a much better chance of prevailing through the last two stages.
When Headless Paladin dropped to 40% HP and descended onto the ground, Ruling Sword still had over 70 players left.
