14 dresspheres, almost 200 abilities to learn and n AP needed. It will take much time, unless you combine two acessories (it have nothing to do with the alchemist dress): Key to Sucess and AP Egg. To earn the Key to Sucess, forget that the Guado exist. DON'T stop Garik from starting war against them, and also complete all missions in Moonflow (you won't be able to get the Baralay Sphere). The AP Egg will require a little work and luck: you must win it playing Blitzball in Luca, on Tournament mode (if it appear as the first prize: I've played 4 times and just now it appeared - and I have to face the Luca Goers!!!). The Key gives to the equiped person the Double All ability (since AP, EXP, Gil, to HP and strenght), and the Egg triples the amount of AP earned, what gives 6 AP per command, and used with non-lethal abilities (such as pray, bio, etc.) will be really easy to master all dresses. NOTE: It doesn't work with the special ones, since you lose all item-given abilities.
