Snipe is an offensive spell used by the Terran Ghost to quickly eliminate vital Biological units in the opposing army. The Snipe spell can be used while the Ghost is cloaked and deals 25 (+25 vs Psionic) damage to an enemy unit regardless of armor.
In competitive play Snipe can be used to quickly dispatch enemy caster units such as the Protoss High Templar and the Zerg Infestor, as both can be killed with only two shots at long range. At its range of 10, it also out-ranges the High Templar´s Feedback by 1, (9 range) and the Infestor´s Fungal Growth by 2 (8 range), though it has a 0.5 second casting animation. While Snipe can be used for picking off all units carrying the Biological attribute, units featuring the Light attribute are rarely worth the necessary APM-Investment, as it would only result in a marginal amount of additional damage compared to the 20 (excluding upgrades) damage that a Ghost deals with its general attack against light units.
Since it takes two EMP Rounds to stop a full-energy High Templar from casting Psionic Storm, Snipe is often times used instead of EMP, especially if the High Templars are spread apart (reducing the effectiveness of EMP's AoE). It takes two Snipes to kill a High Templar. By killing the High Templars rather than simply draining their energy, the Terran player also prevents them from being morphed into Archons during the engagement.
Due to the 0.5 second starting animation delay of Snipe, Feedback from a High Templar can often times kill a Ghost before he is able to Snipe a second time.
Is rarely used, since the only Terran unit that has the Psionic affix is the Ghost.
Infestors and Vipers are both Psionic and take full damage from Snipe, requiring two and four Snipes to kill, respectively. Snipe can also be used to quickly dispatch Queens, which take four Snipes to kill.
In Combination with Other Spells
Snipe can be very effective against Protoss High Templars in combination with EMP if the Protoss opponent is not microing his Templars effectively. Casting EMP and then sniping the enemy Templars can be devastating to Protoss ground attacks.
