How to Unlock
A side boss of Island 4. Buy the Professional Boss Lure and cast the rod to summon it.
Special Bait
How to Get the Bait: Professional-tier boss lure for Island 4 (the same tier that catches Tuna as a regular catch).
Boss Mechanics
Charge Attack, No Room to Kite
An assault-type boss: it promises a charge and goes rigid when the charge fails. Island 4 is very small with no kite space, so dodging is not the plan β firepower is.
A Small Island Compresses the Fight
With no open ground, every failed engagement costs white patience bar. The fight rewards bullet upgrades over movement.
Step-by-Step Strategy
Bullets Over Movement
- Upgrade the bullets before summoning β do not expect fancy sidesteps to carry the fight.
- When it charges, answer directly with the shotgun instead of running.
- Keep damage continuous and kill it before the white bar empties.
After the Kill: Keep the Corpse
Pick up the Tuna corpse and place it on the ground β the Albatross will use it as bait. Selling or discarding it breaks the cheapest route into the Island 4 flying boss.
π‘ Do not sell the mission loot before checking which NPC or boss wants it.
