The junk shop serves as the game's weapon shop from previous Final Fantasy games, offering a list of advancements for each character. Upgrading a weapon in the Steam version earns the player the achievement Handyman. Junk Shop is also an ability learned by the Guardian Force Doomtrain, which allows the player to visit a junk shop anywhere via the menu. This is useful for beyond the point of no return, as towns are inaccessible, although the player can still access junk shop within the Ragnarok if they salvage it from the Kashkabald Desert.
