Killsight (キルサイト, Kirusaito?) is a gameplay mechanic in Final Fantasy Type-0. It allows any attack hitting the enemy to be an instant death attack, when locked onto an enemy, by holding // on an enemy.
When active, a red symbol appears on the opponent, and when hit at this moment, the enemy will be killed immediately. The criteria for Killsight depend on each enemy, but it often activates when they are about to attack, or right after they have attacked. In preemptive strikes all enemies may start with a prolonged Killsight status, which allows the party to finish them off quickly. When an enemy comes out of Rage Mode, it will have Killsight status for five seconds after enabling a quick defeat. Killsight also determines phantoma drops.
When the active leader lands an attack on an opponent without Killsight, it will not appear on an opponent immediately after, and may be skipped until the opponent repeats the animation initiating a Killsight. If an ally lands an attack on an opponent with Killsight, it will disappear. There will be no critical hits on an opponent with Killsight. Landing an attack on an opponent with Killsight can replenish the Ability Gauge substantially. When damage is absorbed from an attack with an element that hits the opponent with Killsight, it will have no effect.
Killsights, like Breaksights are most easily employed by ranged fighters, like Cater, King and Trey where they can hit opponents from a distance, but Eight, Queen and Jack have little delay between button presses and issuing their attacks so can be used effectively too.
