Rescue Riddel and Return to the Manor

Having defeated Guillot as part of the Viper Manor Rescue (Another World) Quest, go back to Viper Manor (Another World) and go to the room on the right of the throne room (previously blocked by an enemy).

In the next room, move the four snake statues to the slots in the ground, then open the treasure chest from behind.

You'll get a note from Solt and Peppor that they've taken a treasure. This serves as a clue as to where to go next.

Get the Stolen Memento Pendant from Isle of the Damned (Another World)

Next, you'll need to visit Isle of the Damned (Another World) with Karsh in your party to track down the stolen treasure. Defeat Solt and Peppor to receive the Memento Pendant.

Take Riddel to the Forbidden Island and Defeat Dario

After defeating Dario and a quick cutscene, the Masamune will fuse with Serge's Sea Swallow and transform into the Mastermune!

How to Beat Dario

Mastermune vs Spectra Swallow

Mastermune Has Higher Crit Rate

While the Rainbow Weapon of Serge, the Spectra Swallow, has higher attack power than the Mastermune, the Mastermune is still the better weapon due to its high critical rate.

Pair the Mastermune with accessories that increase Serge's attack alongside the Sunglasses and Serge will be a force to be reckoned with, dealing explosive damage.
