Demon Wars World Change/Spoiler

Go to the Hero Cave, north of the city of Edron, . Follow the common path to the main floor where many of the Hero Cave Quests are found. Go through the portal to get into a safe room with the NPC A Dark Priestess. In this room there are stairs which will lead you to the middle of the Demon Wars cave.
To the east the Askarak Demons reside, and to the west the Shaburak Demons.
You can ask Guide NPCs about the demon war in order to check its current state. The possible messages/stages are:
* "The demon war is in a stalemate once again." — No faction has any advantage.
* "The Shaburak demons are in advantage right now." — Shaburak Lords spawn on the upper floors of the western tower.
* "The Shaburak have summoned their leaders and dominate the complex." — Shaburak Lords and Shaburak Princes spawn on the upper floors of the western tower.
* "The Askarak demons are in advantage right now." — Askarak Lords spawn on the upper floors of the eastern tower.
* "The Askarak have summoned their leaders and dominate the complex." — Askarak Lords and Askarak Princes spawn on the upper floors of the eastern tower.
In order to change the state of this world change, there must be a difference in kills between the two demon factions at the Server Save. The difference needs to be at least 100 to progress to the next stage. If the war is on a stalemate and the difference is greater than 400, however, the Demon War will go directly to the stage where the Princes spawn.
