Third Eye
From Final Fantasy Wiki
Third Eye is an ability available to Samurai in Final Fantasy XI starting at level 15. It can be used once per minute and lasts for thirty seconds.
When active, the next physical attack is evaded. No shadow images are created, so it is not a "Blink" status. Third Eye can evade multi-hit attacks, but not area of effect attacks.
The effect of Third Eye is improved when used in combination with Seigan.
On a successful evade, there is a chance for a counterattack or for Third Eye to remain active. The chance of Third Eye remain decreases during its duration.
The chance of counterattack is enhanced by wearing the Saotome Haidate.
The ability may have been named after an accessory from the Chrono Trigger series.
