History of Blink

'''Blink''' is a movement ability in Destiny 2. It is the Arc 3.0 movement upgrade for the Arcstrider Hunter subclass, and the Warlock Voidwalker also uses it. While airborne, pressing Jump teleports the Guardian a short distance.

Mechanics

The teleport resets vertical momentum and travels along the Guardian's current momentum, or upward if there is none. It stops at any obstruction.

The listed cooldown is 5 seconds. A second cast is available after 1.5 seconds and a third after 3 seconds. The cooldown starts with every cast, so the recast and third-cast timings depend on when each use happens.
