Treat the preserved Bowhead body as the bridge to the encounter. Save first, restock completely and use long, controlled damage cycles rather than exhausting ammunition in one burst.

Recommended preparation

The goal is not a mathematically perfect build; it is a loadout that lets you move, recover and finish the hand-in without restarting the island.

  • Fully upgraded preferred weapon
  • Automatic backup
  • Maximum practical ammunition
  • A stable host and recent save

Fight plan

  1. Confirm the current trigger.
  2. Save before committing the body.
  3. Maintain clear roles in co-op.
  4. Finish the hand-in and save again before cleanup.

Route status: Patch-sensitive. Avoid selling a named body part, trophy or bait object until the local quest giver rejects it.

Difficulty and co-op adjustment

Patch 1.0.9 added Easy and Hard. Easy reduces creature health by 25% and damage by 50%; Hard increases health and damage by 25%. In co-op, spread out, assign one item carrier, and call reload windows instead of emptying every weapon at once.
