Ghost (Legacy of the Void)
- This article is for the Legacy of the Void multiplayer version. For the previous expansions' multiplayer version, see Ghost (Wings of Liberty and Heart of the Swarm). For the Wings of Liberty Single Player version see: Ghost (Wings of Liberty Campaign).
The Ghost is a specialized infantry unit built from a Barracks with an attached Tech Lab once a Ghost Academy has been constructed. The Ghost stands as an Anti-Spellcaster unit and high damage versus Light units.
Steady Targeting deals 170 damage regardless of armor to any biological unit at the cost of 50 energy. It cannot be queued to multiple units, so it is mostly effective against high health biological units.
The Ghost's Cloak allows it to render itself invisible to enemies without detection. This is generally used to get the Ghost into a good position to EMP or Steady Target an opponent, or to sneak into a base for a Nuke. If using the Cloak to setup an EMP, you must keep an eye on the energy bar as it could prove disastrous if you do not have enough Energy left to cast EMP against various armies.
The EMP Round is the Ghost's most important spell against Protoss. The AoE shot will remove 100 energy (and shields, if applicable) from all units/buildings under its effect. This is essential for use against Protoss opponents for many reasons. The spell effectively does up to 100 damage to anything it hits and can nullify many dangerous Protoss units. Used against a High Templar, the Ghost can prevent the use of Psionic Storm. It also reveals any cloaked units within its radius for a short time, rendering them vulnerable until the effect wears off (though it will not reveal burrowed units). The EMP Round can also be used against structures, where it can damage the shields of Protoss buildings or drain energy from an Orbital Command.
The Tactical Nuke is another ability of the Ghost and will allow the unit to call down a Nuke on a target location provided the Ghost Academy has a Nuke ready and that the Ghost can channel for the full-time. The Nuke is a devastating ability that deals terrible damage to any buildings or units that it hits. However, the cost of using Nukes is very high and requires a hefty amount of gas and minerals to tech to. The long call-down time (20 seconds) also renders it ineffective against units, as they can easily move away.
This upgrade is researched from the Ghost Academy.
Ghosts can be an essential support caster for this match-up, for the use of their EMP alone. Well placed EMPs from a handful of Ghosts will devastate an opposing Protoss army, eliminating the majority of their shields and nullifying any casters that they may have. This is especially helpful against heavily shielded units such as the Immortal, and also entirely removes the impact of High Templar and Sentries from the battle. In a pinch, EMPs can be used to reveal Observers and Dark Templar for a short time. The Ghost Academy can often be seen being built soon after the Terran takes his third base. However, MarineKing has shown some early Ghost timing pushes off 1 base with great effect against expanding Protosses with Sentries.
EMP can also be used on Terran's own units to prevent them from taking damage by the High Templar's Feedback ability. This can also come in handy when Medivacs are (solely) being employed for their transportation capabilities.
Ghosts have little practical use in TvT, though they can be used for Nuke rushes. Their EMP can render Medivacs useless for a short period of time as they require a minimum amount of energy in order to start the healing process. Even if the Medivac reaches that threshold, its healing consumes more energy than it can recharge so its effectiveness remains impaired. EMP can be also be used against Orbital Commands, thereby dealing indirect damage to the opponent's economy, or to create an opening for a Nuke by denying the enemy a counter-scan.
Banshees and Ghosts can be decloaked and - being stripped of all their energy - kept from re-cloaking for at least a minute. A drained Raven is reduced to nothing more than a detector and even its Point Defense Drone can be depleted - although the Ghost can dispose of it conventionally relatively quickly due to the bonus against light units.
In the GSL, TLO used nukes to great effect in TvT. TLO would begin to nuke established tank lines or fortified positions, forcing them to move back or be destroyed. As the enemy unsieged, TLO would move forward and siege inside the nuke's blast radius. Once TLO was set up and the enemy was disorganized, he canceled the nuke.
Ghosts can be used for Nuke rushes, but Steady Target can be vital in sniping high profile targets such as Overseers and Infestors. Ghosts are also sometimes used to support Bio armies with Steady Target and their 10+10 damage against light units. Ghosts can use Steady Target against dangerous targets like Brood Lords and Ultralisks to greatly damage Zerg opponents.
ByuN has popularized Ghost usage against Zerg, notably in his games against Zenio in the GSL with its EMP ability to drain the energy off Infestor to prevent them from getting Fungal Growths off on the Terran bio army.
