Raises Counter activation rate.Final Fantasy IX description
Eye 4 Eye is a support ability learned by Zidane for 60 AP from the Flash Hat and Ninja Gear, Steiner for 35 AP from the Kaiser Helm, Freya for 35 AP from the Kaiser Helm and Rubber Suit, and Amarant for 50 AP from Flash Hat, and Ninja Gear, and requires 5 Magic Stones to equip. It increases the Counter activation rate, even if an attack misses the user, by changing the formula for Counter from "If Spr >= Rnd (0...99), Counter attack is initiated" to "If (Spr * 2) >= Rnd (0...99), Counter attack is initiated".
Eye for an Eye is an Arcanist ability available at level 34. The ability creates a magicked barrier on a single ally for 30 seconds that will have a 20% chance to inflict a status effect to lower the enemy's attacks by 10% for a period of 20 seconds when hitting the ally with the barrier. The effect of Eye for an Eye can be placed on the user's party members, pets, and chocobo companions. The ability has an instant cast time and has a recast time of 180 seconds. Once the player learns the Enhanced Eye for an Eye trait at Arcanist level 44, the cast time for Eye for an Eye is reduced to 120 seconds.
The ability can be used by all classes for cross class, but only the Summoner, Scholar, White Mage, and Black Mage jobs may use the spell as a cross class skill. However, only Arcanists, Summoners, and Scholars have access to the Enhanced Eye for an Eye effect.
Eye for an Eye is the job level 11 command ability for the Swordmaster. It triggers at the start of the turn. Whenever an ally takes damage, counterattack with a powerful physical attack. Does not apply to reflected magic damage.
An eye for an eye is the principle that a person who has injured another person is penalized to a similar degree, or according to other interpretations the victim receives the value of the injury in compensation.
