Octopath Traveler 2 - Nameless Island

I did not want to come here until even later in the game, but the fact is that we're horribly overpowered for almost everything left in the game. This island holds the missing piece to unlock the superboss of the game, but you need someone who can Inquire in order to get it. Rescue the researcher and get the piece off of him, and then you should have everything if you've followed this up to now.

I have Ochette as the thumb nail since I am going to be using the item we get here on her. Basically, anyone who is fishing for crits (warriors included with polearms) can use the Finisher's Claws to get an even bigger boost to their damage.
