Blink
General Blink icon.
A
blink is usually an instantly cast ability which moves the
controlled unit from one point to another at a short range. Blinks,
unlike other displacement abilities like
Leap or
Force Staff, disjoint any projectile (with the exception of
Death Pulse) targeted on the blinking unit. (
Gyrocopter's
Homing Missile is a unit and cannot be disjointed.)
True Blink
True blinks have very specific parameters that are shared with all
other true blinks: they are point-targeted and do not incorporate any
sort of "travel time," although
Teleportation has a three-second delay. True blinks are disabled while a unit is
ensnared or
entangled.
