The fight is divided into 3 areas. When the last mob in the first and second area reaches 1% HP, they will run away at increased movement speed and open the path to the next area.
The Yagudos, Quadav, and Orcs have very low HP and do not deal very much damage from spells or physical attacks.
The Yagudos, Quadav, and Orcs take extra damage from magic spells.
Demons will appear starting in the third room. The Demons have much higher HP and higher physical damage than the other monsters.
Beastmen will only link with their own family. Orcs will link with other Orcs, but not with Yagudo, Quadav, or Demons.
All enemies agro as expected. Sneak and Invisible can be used if necessary.
Defeating an enemy gives you the possibility of various temporary items similar to those in Nyzul Isle.
After defeating all enemies in the third room, talk to Pesoso again to exit Ghoyu's Reverie.
This burning circle is a lot like the assault Blitzkrieg and similar battles. Waves of really weak enemies. BLU, BLM, RDM/BLM, can all do a lot of damage with AoE spells taking out lots of mobs. AoE WSs can help too.
Operation Snowstorm has commenced! Sir Ragelise has given you the orders to deliver word to the other two nations' encampments; first Windurst, followed by Bastok.
