Patch 3.17 Preview: New Co-op Commander Dehaka

Patch 3.17 Preview: New Co-op Commander Dehaka

The Zerg are known for their ability to adapt and evolve, and no creature desires these qualities more than Dehaka. He grows stronger as the battle progresses, and can be customized to help deal with any enemy you face. His army’s huge array of abilities gives you the flexibility to adapt to anything a mission can throw at you. Dehaka leads his pack with the cunning and ferocity that the Primal Zerg represent.



Dehaka and his pack of primal Zerg have a well-established history. The primal Zerg hunt down their prey, gaining strength and evolving new abilities as they defeat their enemies and harvest their essence. Dehaka was another Commander who was an obvious choice to become a controllable hero for Co-op missions. We wanted to incorporate the essence hunting aspect, but do it in a way that was different than Abathur. Abathur focuses on the collection of biomass to evolve his army. Dehaka and his primal Zerg are based on a hierarchy, with the strongest being the pack leader. Since Dehaka is the leader, he is the only one that gets to taste that sweet, sweet essence and use it to mutate and grow. The rest of his army is forced to fight each other for the chance of consuming essence and evolving into more powerful forms.

It was important to us to preserve the fantasy of the primal Zerg. Here are a few examples of how we did that:

  • Drones don’t morph into structures, they summon primal beasts to support Dehaka by sacrificing themselves as the lure.
  • Primal Hives and Wardens can uproot and fight.
  • Primal Zerg don’t use a hive mind to function and thus don’t require overlords.

When Dehaka returned to Zerus, he dominated the primal pack leaders that rose in place of the ones Kerrigan had eliminated. The new leaders, Glevig, Murvar, and Dakrun now follow the strongest primal Zerg, Dehaka. Not only do these primal leaders provide their packs to support Dehaka, they also offer upgrades to the pack themselves, and can even be called into the battle to fight for Dehaka’s cause temporarily.

The main focus of playing Dehaka is the direct control of his hero unit, collection of enemy essence, and making choices for unlocking new abilities during the mission. As Dehaka picks up essence from fallen enemies, he will grow in size, gaining health, attack damage, and mutation points, which he can use to unlock new active abilities and passive upgrades. By the end of the mission, Dehaka should be a nearly unstoppable force of nature rivaling anything we’ve ever seen in Co-op.

Dehaka’s primal underlings must be kept constantly at attention. You can order them to fight each other to prove who is strong and worthy to serve their leader. Each of his basic units can evolve into a new form, becoming a new unit with new attacks and abilities. Choose when to order your minions to perform primal combat and evolve your army to fit your needs.

Gene Mutation
Primal combat evolutions have a change to mutate, providing permanent passive bonuses that can increase life, attack speed, grant life leech, and more.
  • Know when to combat evolve your units. These evolutions change the unit’s roles. Primal Ultralisks can evolve into Tyrannozors, giving them an anti-air attack. Primal Hydralisks can become an anti-armored siege unit, the Impaler.
  • Dehaka is the most important part of your army. Make sure to keep him alive and collect essence as often as possible.
  • Getting ahead of the power curve is key. Dehaka starts off small and weak early on. Fortunately, he spawns in faster than any other hero in the game, which gives him a head start in building up power.
  • Dehaka’s Devour ability is his most important ability. Be sure to have at least one point allocated to Devour. This ability gives Dehaka access to a variety of temporary powers that are critical to victory (healing, damage, speed, armor, cooldown reduction, etc.).
  • Powers absorbed are dependent on enemy unit types (biological, armored, light, massive, psionic, etc). Learn the different types of powers available and which enemies will provide that power. Eating the right food at the right time can make a huge difference.
  • An advanced tactic for Devour is to use it just before an enemy is killed. The cooldown is based on the amount of life the unit had when you eat it. The temporary powers granted are the same no matter how much life the enemy has.
  • Dehaka’s Leap ability is great for dealing area damage as well as giving him mobility. Be careful, though – if used too recklessly, he may not have an escape. If you use Leap to jump into the fray, be sure to Devour enemies to stay healed, or use the level 3 version to gain temporary armor.
  • Make early choices for Dehaka’s mutation upgrades based on the enemy AI composition.
  • Detection is provided by Primal Wurms. Be sure to keep some charges of Greater Primal Wurms handy—or, once you’ve unlocked the Deep Tunnel ability, build extra Primal Wurms at home and tunnel them over when needed.
  • Weapon and Armor upgrades are found on the Primal Hives. All primal units benefit from these upgrades so a mix of melee, ranged, ground or air units can be combined to create a pack that best fits the mission.
  • The tech path is simple but critical. Make sure to summon all structures as soon as possible, unlocking tech as well as top bar summon abilities.
  • Devour drone on Dehaka’s Den allows him to recover quickly allowing him to be extremely aggressive. Using Devour drone early on might be necessary if you need Dehaka to recover quickly, but it will hurt your economy so be careful. Late game it may be a good idea to build up some spare drones or remember to replace them if Dehaka decides to have a snack.

Dehaka and his primal Zerg will be available for purchase with the release of Patch 3.17.0. What Commander will synergize well with this behemoth? Who would win a fight between Dehaka and Abathur? Let us know what you think in the comments!
