Disjoint

Disjointing is the act of dodging projectiles, or rather, to remove oneself from being the target of projectiles. A disjoint is recognized when a projectile stops targeting a moving unit. The connection between the projectile and the target is removed, it is disjointed.

Disjointing itself is not granted explicitly by any effects or spells, it is instead granted as a secondary effect to other abilities.

The most common form of disjointing is blinking and becoming invisible. Not all projectiles are dodgeable, and not all types of blink disjoint.

Blink and other positional abilities

Banish
While abilities that can hide heroes from the map makes them invulnerable not all such abilities will disjoint projectiles.

Transformation
Some transformation abilities such as Alchemist's Chemical Rage and Lone Druid's True Form will disjoint projectiles upon activation.

Mirror Image
Mirror Image type illusions will disjoint particles upon activation.
