The Infestor is an offensive spellcaster, meaning that its abilities are used to harm enemy units instead of support the player's units. It can be built after the Zerg player has an Infestation Pit. The Infestor has two main abilities: Neural Parasite and Fungal Growth. Infestors can move while burrowed as long as Burrow has been researched. Infestors must re-surface to cast any spell other than Infested Terran. It may be worth noting that the Infestor has the furthest range of vision (10) among the Zerg ground units and retains it upon burrowing.

Neural Parasite

Range: 9 (14)
Duration: 15 s
Hotkey: E
The Infestor temporarily takes control of target enemy unit. The player can cancel this ability, or it will automatically cancel if the controlling Infestor is killed or the targeted unit is moved out of 14 range.
