Birth By Sleep Abilities

The ability system in Birth By Sleep is similar to that of Kingdom Hearts II, but with a little twist. The abilities themselves are basically the same as in previous titles, but the way they are obtained is what has changed a bit.
In order to gain an ability, you first must get it. This is done through the Deck Melding process. When you meld two Commands together, the crystal you use will create a various ability. When you equip the new command, you are given the ability. You, however, only get to utilize it as long as the command is equiped. Once you have mastered the command, the ability then becomes yours even without the command in your deck. This is similar to the Esper/spell gaining of Final fantasy VI.
Since all abilities found in Birth By Sleep are considered "Passive" abilities, they have been broken down into three different categories.
Prize Abilities increase the amount of various prizes dropped by slain enemies, or make it easier to gather them.
Status Abilities increase the power and/or effectiveness of the players various forms of offense/defense.
Support Abilitiesprovide various perk abilities that help in different manors.
Below is the different abilities you can gain, as well as the crystal you need to use to obtain them.
