Short Charge, is a support ability in Final Fantasy Tactics. It is learned by the Time Mage for 800 JP. Swiftness reduces Charge Time in all CT-related abilities except for Aim, Sing, Dance, andJump by half.
There is also a dummied out ability called CT 0 that has a cost of 3000 JP assigned to it, but it is not learnable by any Jobs. Its effect while equipped removes the charge time from every ability. No units of any kind make use of the ability in the game, and it appears to be a debug tool more than an ability intended to be in the game.
