A comparison of an actual unit to a hallucination

Hallucinations are false duplicate images utilized by protoss. On the battlefield, they are useful for drawing enemy fire.[1]


There are at least two types of hallucinations used by the protoss. The first are psionic illusory duplicates of other beings/vehicles, courtesy of psionic powers. This psionic ability to create hallucinations can be used by high templar[2] though the Dark Templar are able to employ a similar technique on their ships.[3] These phantasms are without physical substance.[4]

The second version is technological, and is used by sentries.[5] These hallucinations are composed of solid light and are three-dimensional, able to mimic protoss warriors, vehicles, and constructs. Each replica, while limited in duration, is able to withstand some degree of punishment.[6]

The terran Jackson Hauler demonstrated a similar ability, to conjure up the image of an individual and present it to another person.[7]

Game Effect[]


Hallucination Icon SC1.PNG

The high templar selects a unit, creating two duplicates of it. Hallucinations appear with a blue tint to the creating and controlling player, while all other players will see them as duplicates of the original. Hallucinations do not inflict damage when they "attack", may not cast spells, or produce units (important for hallucinated carriers and reavers), and take double damage from all attacks. Hallucinations last for a limited time and automatically disappear when hit by spells (eg. EMP shockwave, Mind Control).

StarCraft II[]


Sentries produce false copies of units to distract opponents. Duplicates have the same number of hit points as the original but take double the damage. The number of hallucinations created depends on the unit: gateway units spawn in twos, probes in fours, and all other units spawn one.

Hallucinations are instantly destroyed by psionic storm and are detected by detectors.

The sentry can create duplicates of units that the player doesn't meet the tech requirements for, but cannot make hallucinations of dark templar

As of Heart of the Swarm, hallucination no longer needs to be researched.
