Dresspheres, often shortened to "spheres", are the key of the job system in Final Fantasy X-2. Each character must have one and only one active sphere at all times. Which sphere is active can be changed any time (though in battle, changing a character's active sphere takes up their turn).

Dresspheres are not equipped directly, but placed in Garment Grids which are equipped directly. The character will then have access to all of the dresspheres in the equipped Garment Grid.

New dresspheres are acquired throughout the game's storyline. Below is a quick reference guide on how to get all of them and each sphere’s general use or theme.

Dressphere	Use*	How to obtain
Alchemist		Clasko will give it to you during the Chocobo sidequest.
Beserker		Complete the travel agency sidequest in Chapter 3.
Black Mage	Offensive spells	Shinra will give it to you after the floating ruins mission at Mt Gagazet.
Cait Sith		???
Dark Knight		Available in bevelle underground.

Gun Mage		At moonflow after finishing the Guard the Hypello mission in Chapter 1 or by selling 6 tickets in Chapter 2.
