Armed Emeth

If you keep your 👀 open as you go through the game, you should find 7, just laying around in dungeons. They show up on the map you see in the menu screen, so they shouldn't be hard to miss. 2 of them are though. The first is in the Pure Edea Forest. While you can see it going through the dungeon, you cannot access this one until you reach the teleporter in the Imperial Ruins further in the story, about half way through the dungeon. In the screen past the teleporter there's a human only path too small for golems that leads to a room with a bunch of dudes and some...insects I guess? Kill one of the insects blocking the west exit and follow it to the golem.

The other one that is easy to miss is on the hidden island, an island in the northwest corner of the world map. Simply fly over there when post game starts with the airship. Land, enter the hidden island, and grab the golem. You don't need to do anything in the post game to finish this game. Kemco's getting lazy
