Viper (Legacy of the Void)
- This article covers the current multiplayer version of this unit. For other versions see Viper (Heart of the Swarm) and Viper (Heart of the Swarm Campaign).
The Viper is a Zerg flying support caster that requires a Hive. The Viper does not attack. Instead, it uses its spells to disrupt the positioning of enemy units. The Viper is particularly effective against entrenched positions and clustered armies. It can also separate high value targets such as Thors and Colossi from a group so they can be surrounded and killed more easily.
- When a caster channeling a spell is Abducted, it will cancel the spell if the Viper moves the caster out of range of its target.
- Abducting a burrowed unit will cause it to unburrow.
- While Abducting a cloaked unit the unit will briefly uncloak then recloak when the animation ends
- Despite its hostile name, Abduct can be used on your own units and on allied units.
- A group of Vipers on follow command will clump up. This can make it hard to select them individually.
- If a Parasitic Bomb is attached to a unit when you Neural Parasited it, the Parasitic Bomb will no longer deal damage to the unit itself but continue to stick to the unit and damage nearby enemy air units.
Vipers see frequent use in the mid- and late-game stages of Zerg vs. Protoss. Their Abduct ability separates expensive units like Colossi, Immortals, and Tempests from the compact Protoss army and brings them into range of Roaches and Hydralisks. Their Blinding Cloud ability can also be useful against large groups of Stalkers, forcing them to move or Blink out of the cloud in order to attack.
However, it should be noted that Vipers are especially vulnerable against Feedback, as they must move relatively close to the Protoss army to be effective, and they often build up large pools of energy due to Consume. Previously, Zerg players needed to take care not to build up the Viper's energy past 150 if High Templar are on the field, as this would enabled Feedback to kill the Viper in one cast. This is no longer the case after Patch 4.7.1 where Feedback was changed to deal 0.5 damage per point of energy drained.
Vipers can be of great use against a Terran employing either a mechanical or a Marine-Tank army composition. Blinding Cloud is especially useful against Siege Tanks, as the tanks must un-siege in order to move out of the cloud, effectively removing them from the battle. Blinding Cloud can also be used against clumps of Marines and Marauders, zoning them out of choke points and making them easier to hit with Banelings and Fungal Growth. The Viper's Abduct ability is used to pull expensive units like Thors and Siege Tanks away from the Terran's main army, making them easier targets for the shorter-ranged Zerg army.
Against bio play, Vipers are also a good support unit for a Roach-Hydra mid game army. Casting Blinding Clouds on the Terran bio ball will prevent the Marine-Marauder force from firing at the Roach-Hydra force. This forces the Terran to retreat. If the Terran does not micro, the AI will instruct the bio ball to move closer to their target, which makes retreat even harder for a Terran player not paying attention.
Note that Blinding Cloud also affects your own units, and the Terran player can lure the Roach-Hydra force into a trap by feinting a retreat and pulling the Zerg forces into the Blinding Cloud.
As with Brood Lords, it is important to supplement Vipers with additional anti-air, as they are helpless against Terran's long-range Vikings (their Parasitic Bomb ability, though powerful, is rarely fast enough to save them from a Viking attack).
Vipers see less use in Zerg vs. Zerg than in the other two match-ups, but still play a key role. If one player commits to massing Mutalisks, the defending player is advised to tech to hive to acquire a few (3-5) Vipers for their powerful Parasitic Bomb ability. This will destroy the clump of Mutalisks and the ground army will be free to advance. As such, players teching to Mutalisks should only make a handful of Mutalisks (26 or so) to gain map control and tech-switch into a Roach/Hydra style, tech up into Ultralisks, or possibly Brood Lords.
The Viper is a powerful option in the lategame as they help the player deal with Lurker lines with Abduct and/or Blinding Clouds, and groups of Mutalisks/Corruptors with Blinding Cloud. They are useless against Ultralisks, however (Frenzied prevents Abduction). Blinding cloud can be a powerful spell against regular Roach/Hydra balls if paired with Infestor's Fungal Growth ability to prevent an entire clump of enemy units from attacking.
