The Deep Sea Fishing Rod is an important item in the main storyline. Players can only dive into the Demon's Lair and obtain precious offerings through fishing after acquiring the Deep Sea Fishing Rod. In this article, I will provide a guide on how to get the Deep Sea Fishing Rod in the game for your reference. I hope this content will be helpful to all interested players.

There is only one way to acquire the Deep Sea Fishing Rod in the game: players need to complete the side quest from the Researcher. To trigger this side quest, there is a prerequisite condition that the player's main quest progress must have reached Stellar Bay; otherwise, they cannot meet the Researcher NPC.

After arriving at Stellar Bay for the first time, find and talk to the Researcher directly. She will assign a side quest to the player, requiring them to collect three different types of biological specimens. These three species are the Moon Jellyfish, Bioluminescent Octopus, and Firefly Squid, which live in the shallow waters, the island beaches, and the central reefs of Stellar Bay, respectively. To collect these specimens, the player must ensure that each trip out to sea is during the night, as these creatures are not visible in Stellar Bay during the day.

It's worth noting that when catching Moon Jellyfish, players may accidentally catch infected jellyfish. To avoid this, while using the net, players should check the contents of the net every time they catch something. If an infected creature appears, it must be discarded immediately to prevent it from contaminating other specimens, which would result in the failure of the mission.
Once all the samples are collected, return to the Researcher to exchange them for circular parts. These parts are essential for making the deep-sea hook. After obtaining the parts, go back to the blacksmith to craft the Deep Sea Fishing Rod.

The above content is the complete guide on how to get the Deep Sea Fishing Rod in the game. During the process of getting the rod, players will meet a researcher who is an important scientist in the game. While completing the tasks, players can also investigate his background story. I hope that after reading this, you will try it out in the game.
