Read the active objective first

The opening route starts with the lighthouse keeper's current dialogue. Follow the quest text rather than assuming that catching or defeating any creature advances progression.

Complete the Spider Crab handoff

The collected beginner and progression notes connect this quest to the Spider Crab encounter. After the encounter, inspect the unusual result, keep it out of the sell pile and take it back to the lighthouse keeper.

  • Do not sell unknown drops
  • Keep one player responsible for the item in co-op
  • Speak to the quest giver again after the handoff

When the quest appears stuck

Re-read the quest text, verify that the item is still in inventory and return to the lighthouse keeper. If a trigger differs in the current build, treat old community advice as context and follow the in-game objective.
