Primal hydralisk

"Saw ranged primal zerg creatures on battlefield? Based on hydralisk! Primal zerg stole design from Swarm!"

A primal hydralisk

Primal hydralisks are primal zerg creatures based off the Zerg Swarm's own hydralisk strain.

Overview

According to Abathur, the primals stole the hydralisk's essence from the Swarm, and used it to produce their own hydralisks. They were among the first of the Swarm zerg breeds to be adapted into the primal zerg genome, and the evolutionary strength of the hydralisk's essence meant that many of their traits were retained among the primals.

Some primal hydralisks develop mutations that exhibit an increasing number of lurker traits, with many resembling more lurker than hydralisk.

Primal hydralisks are very similar in appearance to normal hydralisks, though they are slightly larger and have greenish-gray carapaces. In the Heart of the Swarm single player campaign, their stats are almost identical to those of their Swarm counterparts.

Primal hydralisks in Co-op Missions have more health than their Swarm counterparts.

Heart of the Swarm

Primal hydralisks appear as enemies, and later allies on Zerus. They also appear as part of Dehaka's pack during the attack on Korhal.

Kerrigan, in her Primal Queen of Blades form, can summon sacs containing a group of primal zerg consisting of primal zerglings, primal hydralisks, and primal roaches.

Abilities

Burrow

Many zerg ground units may burrow, becoming invisible and revealed primarily by detectors, and may not move or attack while burrowed.

Exceptions include:

• Roach, which may move while burrowed
  
• Lurker, which may attack while burrowed
  
• Infestor, which may move while burrowed
  
• Baneling, which can detonate while burrowed.

Some units can unburrow via autocast, causing them to emerge and attack when an enemy moves into range.

The ability is not smartcast.

Hotkey R Cost 2 seconds to burrow, 1 second to unburrow
