Quick answer

Feed the Beer Can to the Lighthouse Keeper, use the returned empty can as bait, then sidestep the Spider Crab’s charge. Attack while it is stunned and stay close enough that it does not waste time jumping.

Prepare the encounter

  1. Earn enough from easy catches to buy a knife or brass knuckles.
  2. Sharpen or improve the melee weapon you handle best.
  3. Buy the Beer Can and feed it to the Lighthouse Keeper.
  4. Take the returned empty can and equip it as your lure.

Read the charge, then punish

The Spider Crab is the first and easiest boss in the supplied walkthrough. Let it commit to a charge, move sideways rather than directly backward, and use the miss-created stun for a short attack window.

The walkthrough reports two to three comfortable hits, with up to four possible. Greed is the avoidable risk: reset your angle before the crab recovers.

  • Do not kite too far away; long distance can trigger jumps and waste time.
  • Watch the white bar below the health pool.
  • If that white bar expires, the boss can escape and the encounter must be repeated.

Finish the lighthouse quest

After the Spider Crab dies, collect the relevant drop and bring it to the Lighthouse Keeper. The supplied walkthrough says feeding him the boss meat completes the first quest and earns the boat keys.
