Lighthouse Keeper: bait, shell and Boat Keys

Use the keeper’s two exchanges to start Spider Crab and unlock the boat, with a separate check for the Radar.

Opening quest and Boat Keys

Route coverage: the documented Patch 1.0.10 progression baseline. Follow the objective and item names shown in your game; these notes do not claim a new playtest of the current patch.

Visit before and after Spider Crab

Your first useful delivery is a Beer. Keep the Empty Beer Can returned by the keeper for the Crab Fishing Rod, then come back with Spider Crab’s shell after the fight.

The second exchange produces the Boat Keys. Protect the shell during any shopping stop: the keeper needs the quest result, not a pile of normal catches.

Check the three objects that matter

  • Before the boss: Empty Beer Can ready on the correct rod.
  • After the boss: shell kept for the keeper.
  • Before sailing: Boat Keys collected and Radar obtained separately.

If the conversation does not advance

Confirm which exchange you have reached and which object you are carrying. Once you have the keys, a missing Radar needs a purchase, not another shell delivery.
