To create a sword for the swordfish, you’ll require a Speartuna Fin initially, and if you wish to max out its potential, you’ll need five more. Keep in mind that this rare fish can be tricky to locate. Here’s an efficient method to find a Speartuna Fin in Monster Hunter Wilds without spending countless hours at every fishing spot:
1. Head to the Eastern Great Forest, where the Speartuna Fin is most commonly found.
2. Use the Fish-O-Matic device to locate schools of fish.
3. Look for the Speartuna Fin among the schools, as it tends to be more elusive than other species.
4. Cast your line when you spot a school containing the fin.
5. Be patient and persistent; it may take several attempts before you catch one.
6. Repeat this process until you have the required number of fins for your weapon upgrade.
