Cait Sith's Limit Break Lucky Girl allows all party members to deal critical hits every time they attack, whether it be a regular physical attack, a command attack such as Slash-All, or a Limit Break. The Lucky Girl is a possible combination in Cait Sith's Level 2 Limit Break, Slots, and is executed by lining up three heart symbols.
Critical status can be achieved in various means, either from the Lucky Stars Limit Break executed by lining up three Cissnei portraits during Modulation Phase, by rolling the combination of 6-6-6 in the Digital Mind Wave reels (without a Modulation Phase), or by equipping the Sniper Rifle or Genji Glove accessories.
Lady Luck learns the ability Critical that makes all of the character's attacks deal critical damage every time. Lady Luck can learn the ability for 160 AP after learning Felicity. Samurai can also learn SOS-Critical.
In the International and HD Remaster versions of the game, the Garment Grids Peerless and Last Resort bestow the Critical status when Yuna, Rikku or Paine pass the red or green gate respectively. The Critical auto-ability can also be given to creatures if they are either equipped with the Peerless Garment Grid or if they are fed a Hero Drink.
The Party Host's Pot Luck ability has a chance to bestowing the party with a status that makes all of their physical attacks critical hits. The chance of the ability being used is random.
