Note 1: This will give infinite Ultimate Specials too(Can keep using followed non-stop on any enemy).
Note 2: This code will add 1 item, instead of use, keep in mind that if you have 99 of an equipment for example, you can't un-equip an character equipped with that item, so, try to keep your gears at around 10.
Note 3: Any skill granting stats effect will be permanent(attack boosters, def boosters, etc). Keep in mind that all ailments will be permanent unless you use an item to remove the ailment.
Note 4: Using this code will let you watch all friendship events, but will give some bugs on shops and stores(like impossible to close the store). Don't play with this active, use, watch the events and deactivate(Untested at second game).
