After you help Freja get her memory back, go to her place, and have her hone your equipment to make it stronger. Before you start to hone, bring at least a few thousand gil, and save the game. When you get to the point where it says that it is at the maximum level and you can still hone it, you may want to save the game again; when Freja tries to hone it past it the maximum level it will have a greater chance to fail. If that happens, reset the game, load the saved game, and repeat until she makes a perfect hone. This may require a few attempts.
