How it works

The event changed between game seasons. The first tab is the newest version.

Chaos Castle

Chaos Castle is a battle field created by Lugard, the god of the heavenly world, and Secrarium, the god of the underworld, for the balance of good and evil in this world. However, travelers started going to Chaos Castle and fighting on the side of Lugard, tipping the balance in disfavor of Secrarium. To restore balance to the battle event, Sacrarium made Lugard an offer and suggested the implementation of a new rule. This rule was for everyone participating in the event to wear guardsman's armor. Lugard, believing the offer to be fair, accepted it.

Unfortunately, Secrarium was betting that darkness in the hearts of the travelers would ultimately lead to hostility and discord among them. Lugard was also aware of the travelers' dark side, but his trust in them didn't waver. Eventually, as the dark god predicted, the travelers began to feud with one another, and Chaos Castle became increasingly... chaotic.

  • Some of the monsters in Chaos Castle have a special Skill called Explosion, which causes strong Knock-back.

  • Using AOE Skills can help avoid Explosion Knock-back.
  • You must be careful when the total number of participants is 40, 30 or 20 because the outer floor will begin to fall and you can fall, which would cause your disqualification.
