Quick answer
Prepare before placing the lure, fight where terrain can interrupt the Pufferfish’s fast approach, and keep its distinct fin or bone-shaped trophy for the quest giver. Ordinary meat does not complete the hand-in.
Prepare before the lure goes down
The archive consistently describes the Pufferfish as a major difficulty spike, but it does not provide stable damage values or a universally best loadout. Enter with reliable damage, healing food if available, open inventory space and a clear reset route.
- Use a weapon whose reload and handling you already understand.
- Clear loose objects that can trap your movement.
- Choose terrain that can break a direct approach without boxing you in.
- In co-op, assign one player to kite and others to fire from different angles.
Control the approach
Do not stand in open ground and trade damage. Keep moving across the boss’s path, use nearby geometry to buy reload time, and take clean windows instead of firing through panic movement.
Co-op helps only when the team spreads the danger. Four players in one damage lane can all be disrupted by the same rush. Decide who is pulling attention before starting.
Take the fin, not just the meat
When the boss falls, slow down. Players describe the required quest piece as a fin, tail or bone-shaped trophy. Collect that visually distinct item and test it at the quest giver before selling any boss remains.
Logbook note: The exact inventory label is not verified in the supplied archive. Shape and quest response are safer identifiers than community naming.
