The progression model

Progression connects the lighthouse, NPC quests, boss encounters, and new-island unlocks. When you feel stuck, return to the most recent quest giver and check whether the current island boss has been summoned and defeated.

  • Lighthouse and first objectives.
  • Island 2 quest and boss chain.
  • Island 3 and later progression gates.
  • Volcano and final-route preparation.

What to check when the next island stays locked

Confirm the island's quest handoff, boss reward, and any coordinates or travel item before leaving. Use the related quest and boss guides below when one of those steps is incomplete.
