Fungal Growth

Fungal Growth (or Fungal for short) is an offensive area of effect spell cast by the Zerg Infestor. Upon casting, a projectile launches and roots all enemy units within the area of effect when it lands, dealing 30 damage over 3 seconds. Affected units can still retaliate against enemies within their range. Like all damaging offensive spells, Fungal Growth maintains its effectiveness as the game progresses because it is not mitigated by armor upgrades, providing consistent damage.

Fungal Growth is an extremely versatile spell, allowing the Zerg player to dictate the battlefield positions in a similar manner to the Sentry’s Force Field spell. For economic harassment, two Fungal Growths will kill any worker units. When used for positioning, Fungal Growth forces the opposing player to hold their ground until the effect expires, or risk splitting their army. This provides the casters army a brief time frame to jockey for a superior position. When Fungal Growth is employed for defense, it can block enemy forces from passing through choke points or ramps. In addition, it is extremely effective at limiting aerial harassment, especially against larger groups of clumped flyers. Fungal Growth can also be used to slow down advancing units, allowing the Zerg player to buy time for hatching units or upgrades to finish, or to soften up an army prior to confrontation.

Vs. Protoss[edit]

Infestor energy use in ZvP is balanced between Fungal Growth and Neural Parasite, varying on the army composition of the Protoss player. Fungal is more effective against larger Gateway-based armies, especially ones that are Zealot heavy, because the immobilization removes the benefit of Charge, and limits their ability to act as damage absorption. Fungal Growth also loses some of its harassment effectiveness in ZvP, because of the fast shield regeneration of Protoss units.

  • Affects Interceptors, holding them in place. Is especially effective if the Protoss player has Graviton Catapult researched.
  • Reveals Observers, Dark Templars, and units cloaked by a Mothership.
  • Prevents Stalkers from using Blink, allowing you to take control of the battlefield with superior positioning.

Vs. Terran[edit]

In ZvT, Fungal Growth is extremely effective against bio armies (composed of Marines and Marauders), and has limited use against other styles of play. There are three main reasons for its effectiveness against Barracks armies. First, it allows the Zerg player to punish Stimpack use by backing off once the bio force is immobile. This causes the Terran army to take Stimpack damage, combined with Fungal Growth’s damage over time. Second, it holds the Terran army in place, maximizing the damage of splash units like Banelings and Ultralisks, and removing the speed advantage and kiting ability that Stimpack provides. And third, it gives the Zerg an easy way to burn through Medivac energy.

  • Reveals Ghosts and Banshees that are using Cloak.
  • Will stop Vikings and Siege Tanks from transforming between their different modes.
  • Does not affect a Seeker Missile.

Vs. Zerg[edit]

Fungal Growth can be used in Roach vs. Roach battles to immobilize a group of enemy Roaches, trapping Roaches in the backfield and preventing an enemy from forming a good concave at the start of the battle. It can also be used to stop Mutalisks from eluding your army or commuting between your mineral lines. 4+ Fungal Growth can also kill multiple Mutalisks (120HP) on their own, should you have no other Anti-Air capabilities.

  • Banelings, despite having exactly 30HP, will survive a Fungal Growth due to Zerg regeneration.
  • Zerg units cannot Burrow or unburrow while under the effect of Fungal Growth. Burrowed units will be revealed for the duration of the spell and no detection is needed for the spell to land.

In Combination with Other Spells[edit]

  • Fungal Growth combined with Blinding Cloud will cause affected units unable to move and fight back when ranged units attack them outside melee range.
  • Fungal Growth can be used to maximize the damage of other offensive spells, like Psionic Storm or Seeker Missile.
  • If Fungal Growth is fired at the site of a Mothership’s Vortex just as it ends, the instant before the affected units have time to spread out, all of the units escaping the vortex will be affected and immobilized in a small cluster.
  • Fungal Growth can be used in combination with Infested Terrans as an effective form of worker harassment.
  • The 20% damage bonus from Corruption applies to Fungal Growth damage as well.


  • Fungal Growth affects all enemy units within its 2.00 explosion radius. The applied debuff fully immobilizes affected units – except Ultralisks and Brood Lords due to their passive Frenzied ability.
  • Only affects hostile units, allowing it to be cast over a battle with no negative effects to allied forces.
  • Cloaked, Permanently Cloaked, and Burrowed units will be revealed by the debuff.
  • Affected units are unable to move for the duration, but can still attack, repair, and use other abilities and spells within range. However Zerg units will not be able to Burrow (or unburrow); Stalkers cannot Blink; and Warp Prisms, Siege Tanks, and Vikings cannot switch between modes.
  • Multiple Fungal Growths do not stack, but each new spell resets the 4 second duration.
  • Affects Larvae, which will die to one Fungal Growth unless they are morphed into a unit.
  • Fungal Growth does not dispel Hallucinations (As Ensnare did in Starcraft:Brood War).
  • Units under the effect of Fungal Growth cannot be transported. However, unaffected units can load into an affected Medivac, Overlord, or Warp Prism.
  • Setting “Show Flyer Helper” to Always in the options menu can make Fungal Growth-ing air units much easier.
