Most Annoying Mechanism in Dragon Flame Lair Instance EXPLAINED! | ROX

So, you know when you being put asleep then suddenly a bunch of "black hole" appears from beneath you, unable to escape, and ultimately die?
This skill is called "Requiem Dragon Breath".
Skill Description: "Mutant Dragonoid puts the world to sleep, and stirs the air pressure to deal Wind Magic Damage! Anyone daring to disturb the slumber will be haunted by endless resentment, and takes additional true damage from the air pressure."

Basically, when the Mutant Dragonoid is sleeping, all player must not attack or cast any spells(yes, anything including buffs). If you accidentally do any of these actions, upon waking up, the boss will deal 100% True DMG and all player who does not have the protection of Sacred Blessing(and other buff alike) will die. Not only that, some shadow dragon will also appear, making the battle even harder.
