How to get Tuna
- Reach Rocks Island. It is stage 4 of the main route and follows the red Radar marker.
- Equip the Fishing Rod and use Professional Boss Lure (dedicated encounter; also reported in the Professional Lure pool) only after the fight area, ammunition and healing are ready.
- Farm Professional catches before buying the one-use boss lure. After the encounter starts, follow the dedicated fight plan and preserve its route item or body.
- Secure the encounter result. Route result: The defeated Tuna body, which is the Albatross trigger. Check the base creature entry before marking this page complete.
Protect the encounter result
The Tuna route may depend on a trophy, body or hand-in after the fight. Secure that result before selling, cooking, gambling or sailing away.
Tuna encounter notes
Tuna is both a dangerous catch and a quest object; selling its valuable body stops the story chain.
Prepare
- Farm Professional catches before buying the one-use boss lure.
- Clear a safe patch of grass where the body can be staged afterward.
- Make sure no one in co-op cooks or sells quest-critical catches by mistake.
Fight plan
- Keep the fish in view during its leaps and fire during predictable landings.
- Avoid the death-and-spawn edge case fixed in Patch 1.0.10 by fighting with a stocked health reserve.
- Place the defeated body on land only when ready for Albatross.
