So many Octopath Traveler 2 side stories, like “Plans from a Ruined Nation,” involve learning about an item you need and then needing to steal/buy/scrutinize/inquire to get them. Which, if you’re going out of your way to always check NPC inventories and, say, steal with Throne, ends up being handy! It means you can easily complete quests with a lot of backtracking. This is a prime candidate for that.
Okay. So. First, if you’re in Sai, you’ll find someone in the eastern part of town in front of a dilapidated building. You’ll see treasure chests you can’t reach. Talk to the person, who turns out to be a Master Carpenter, and you’ll learn the Fort Orochi Plans to repair the building.
Said Fort Orochi Plans are in Canalbrine in the first floor of the tavern. A Former U Carpenter is sitting at a table. Get the plans from him. You can do this in a number of ways, but Throne quickly grabbed them via stealing when I was playing.
After that, return to the Master Carpenter in Sai to complete the Octopath Traveler 2 side story “Plans from a Ruined Nation.” You’ll immediately get 6,500 leaves and a Tough Nut (M) as a reward. You can also access the two chests there now, which contain a Refined Sword and Battle Hatchet.
Octopath Traveler 2 is available for the Switch, PS4, PS5, and PC. A demo is available.
