Dark Link allows the user to generate three crystals in a trigram formation and project rays that fuse and become a giant beam of radiant energy.

Dark Link (ダークオブリンク Dāku obu Rinku?, lit. "Dark of Link") is a technique that appears in Kingdom Hearts Birth by Sleep. It allows the user to shoot a giant beam of radiation. It is the opposite of Vanitas' Dark Cannon attack.

Mechanics

Dark Link is a class A Shotlock that has a max lock of 20 and deals dark damage. If Vanitas uses Dark Cannon or Dark Spiral at the same time as this Shotlock is used, a clash will initiate between Vanitas and the user, which can be won by rapidly tapping   (  in Japan).
