As a SEED Ranger, you’re the one-stop shop that all townsfolk go to when they need help in Rune Factory 5. They will sometimes ask you to kill a certain number of monsters just to want a specific item, which is a common request in the game. One of these fetch quests comes from Cecil asking you to deliver him an octopus that can be difficult to find. So where do you get this elusive sea creature?
You can catch a squid at Rigbarth Beach. As previously mentioned, squid can be difficult to find and are not often found in the areas in which they are found. So when you are tasked with finding one, just be patient and keep trying until you finally get one.
Alternatively, you can purchase a Squid from Serendipity after it’s first upgraded by Hina when she’s working. The Squid costs 400G. However, since it takes a bit of lumber, rocks, money and SEED points to upgrade the general store and you have to wait for Hina to work there, we recommend catching the fish yourself if you don’t have the necessary materials, to pay Palmo for the upgrade.
