Luck (こううん, Kōun?) is a recurring stat in the Final Fantasy series, although it is not as common as other stats. It usually affects things such as critical hits and finding rare items, but also can influence other stats like Evasion and Accuracy. In other games, where there is no luck stat, there are other stats which determine these instead.
Luck makes its first appearance where it, along with character level, was meant to determine the success or failure of fleeing a battle. However, the calculation did not work exactly as intended in the NES version, resulting in the Running glitch.
The higher Zack's Luck, the more critical hits and better Item Drops he gets. The player increases the Luck stat by equipping accessories and Materia that give boost to Luck. The player can boost the Materia's Luck stats via Materia Fusion up to +100 per Materia.
Players are able to junction magic spells to characters' Luck stats. This requires equipping a GF that has learned Luck-J either on its own or with a Luck-J Scroll. Luck affects a character's hit accuracy (unless they already have a 255% hit rate), evasion, and critical hit ratio. Because Squall and Seifer already have perfect accuracy and trigger their critical hits manually, they only benefit from the increased evasion.
Luck is not a stat in Final Fantasy IX; its function is instead served by the Spirit stat.
Luck affects evasion, accuracy, the character's chance of critically hitting, and the enemy's chance of critically hitting. It can only be upgraded via the use of a Fortune Sphere to activate a Luck node on the Sphere Grid.
Although raising the Accuracy stat gives a better hit rate in most cases in the short run, it has its limitations. Some enemies are so evasive that no matter how high one's Accuracy is, they will never have above a 25% chance of hitting them. Other enemies may not have any Evasion, but are evasive directly due to their Luck stat. While under Darkness, one's hit rate is reduced to 10% regardless of Accuracy. In all three cases, raising Luck will improve the chances of hitting, while raising Accuracy will not.
On the other hand, an increase of 1 Luck has the exact same impact on evasiveness as an increase of 1 Evasion. For example, the most accurate attack in the game (belonging to Dark Ixion) requires a combined total of 290 to ensure dodge any evadable attack; it does not matter whether this is 255 Evasion and 35 Luck, or 35 Evasion and 255 Luck, or anywhere in between. In addition, the most Luck stat in the game (belonging to Dark Mindy) requires 230 to ensure critical hits even with Overdrives.
Luck is generally the sole determinant of critical hits; the chance of inflicting one is simply the user's Luck minus the target's Luck. However, when using physical attacks, equipment (including armor) generally provides a small critical hit bonus. This is 3% for most equipment, but drops from Penance give 10%, and drops from all Dark Aeons or certain Monster Arena creations give 6%. Some enemy attacks also carry a bonus critical hit chance.
Enemies that drop equipment with +6% Critical Bonus in the Monster Arena are:
- Area Conquest: Malboro Menace, Jormungand, Don Tonberry, and Catoblepas.
- Species Conquest: Fenrir and Sleep Sprout.
- Original Creations: Earth Eater, Greater Sphere, Catastrophe, Th'uban, Ultima Buster, Shinryu, and Nemesis.
Despite common misconceptions, Luck does not affect anything apart from accuracy, evasion and critical hits.
The abilities Luck and Jinx claim to increase and decrease the targets' Luck stat respectively, but do not give the full effect of higher/lower Luck. Each use of the Luck ability adds 1% to accuracy and 1% to the chance of landing a critical hit; unlike a genuine Luck stat increase, it has no impact on evasion or the chance of receiving a critical hit. Jinx reduces targets' evasion chance by 1%, and increases the chance of landing a critical hit on them by 1%, but has no impact on the target's accuracy or their chance of landing a critical hit themselves. The effects can be stacked up to five times.
Luck is a Clan Privilege that raises Evasion and chance of the Opportunity Command.
Luck, represented by the light element, is one of Layle's five stats, which, like the other four, can be increased by equipping accessories. Luck determines many things, most notably the rate at which enemies drop materials.
Luck affects many aspects in the game. Luck can be raised with a number of accessories, and some equipment sets, such as the Genji set. Having higher luck increases the rate EX-Cores appear. Also, if a character has high luck, they experience a higher percentage of Battlegen accessories being dropped. Lastly, high luck increases the chance of enemies dropping their accessory or equipment during battle.
