What to do
- Practice the five-island quest chain before starting the clock and note where each protected drop must be delivered.
- Use a fresh save and follow only objectives that unlock the next island. Buy upgrades when they directly prevent failed boss attempts.
- At Lighthouse, Forest and Desert, pre-plan the quest bait and the exact NPC hand-in so travel time is not wasted.
- At Rocks, preserve Tuna for Albatross. At Volcano, prepare five fish for the Scientist and the final body-to-crater chain.
- Keep the timer running through the last Scientist hand-in and RHIB departure. Record splits so your next run targets the slowest stage.
