With this code, it doesn't dump AP to other skills.

With this code, the end garment grid is also equipped.

With these codes, they wont show up in the menu screen, but they are active. The abilities it gives include Break HP Limit, Break Damage Limit, Break MP Limit, Auto-Counter, Gil Hunter, Item Hunter & more.

With this code, it is always calibrated whether you fail or succeed.

With these codes, using both the Have All Fiends & Have All Fiends Oversouled gets you "The End" garment grid the first time you access the bestiary after entering the code. Don't enter the oversoul code without using the bestiary complete code or completing the bestiary yourself. If you do, the fiends will appear in the bestiary, but you'll get the same message you would for a blank line. I don't think it causes problems, but it certainly could be confusing.

With this code, it is 9999, but it will be 999 in battle if limit is not broken.

With this code, you will hit for 9999 damage.
