Class choice influences abilities and role in cooperative dungeons, allowing teams to combine varied strengths for challenges.

  • Experiment with multiple classes to find a playstyle that matches your preferred combat rhythm.
  • Consider how a class’s abilities might complement teammates in dungeon groups.

New Main Story Chapter

The chapter titled “Daydreams & Songs of the Night” begins with a distress letter from Fafala and strange village phenomena. Players follow clues tied to a mysterious melody.

The narrative promises a deeper truth behind the song, encouraging players to investigate the night‑time mystery.

  • Read the distress letter carefully; it sets the direction for the next objectives.
  • Pay attention to environmental audio cues that may hint at the mysterious melody.

Six New Dungeons

Season 4 adds six new dungeons, including “Mirror Judgment” and “Cavern Zero.” They roll out progressively throughout the season, offering fresh challenges.

These dungeons reward level‑320+ gear and exclusive seasonal cosmetics, expanding end‑game content.
