Trash and route risks

What to stop between bosses.

  • Assign interrupts, dispels, and crowd control before each wing.
  • Use client-compatible boss mods and verify that custom scaling has not changed tank-buster timing.
  • Repair, rebuff, and update the raid note between wings rather than after the next pull.

Quests and unlocks

Do not leave rewards behind.

  • Archivum Data Disc and Keeper sigil quests lead to the Celestial Planetarium and Algalon.
  • Thera scaling, lockouts, or quest availability may differ; verify in game.
