Probius is Ranged Specialist Hero based on the protoss probe unit from the StarCraft universe, first introduced in Heroes of the Storm.[1]

Since his activation, Probius has always wanted to prove himself. He may be small, but he made a big difference by warping in a critical pylon during the retaking of Aiur. As the bravest of probes, Probius is eager to fulfill his purpose in the Nexus.


During the early stages of the End War, Probius took part in the Reclamation of Aiur as part of an akhundelar under Kaldalis. During the initial landing, Probius was able to set down a warp beacon for a pylon while the conflict raged around him. Though the akhundelar suffered heavy casualties, Probius's pylon allowed reinforcements to be warped in at a key moment, allowing the Daelaam to establish to a beachhead on Aiur.[2]

Gameplay Summary


  • Strong area control
    • With sufficient backup, Probius can safely place area denial with Warp Rift and Photon Cannon, it can choose to hide behind these defenses with enemy being distracted, and both abilities have formidable staying time.
  • High burst and area damage
  • Flexible vision granted by Warp In Pylon
  • Null Gate has exceptional lockdown strength in enclosed area
  • Strong in waveclear and siege


  • Fragile
  • Requires set-up time
  • Needs a front line
    • Probius is in dire need of hero who can protect it from divers who may shut down or kill it in a split second
  • Vulnerable to isolation
    • Separating it from its base or allied heroes will render Probius or the other hero easy target

Talent Builds




Probius needs a strong frontline hero who can take a lot of punishment and act as a wall between him and his opponents. It also helps if his frontline consists more of heroes who do not tend to dive the enemy team, as that leaves Probius in a vulnerable position. Arthas’s commanding battlefield presence and great peel between Howling Blast and Frozen Tempest make him a good tool to keep the enemy team from getting to and quickly eliminating Probius in teamfights.

Like Probius, Jaina is also great at controlling space and zoning enemy heroes away from her team for a time. Jaina’s constant slows are great for setting up Warp Rift combos as well as for peeling enemies away from Probius when he gets in danger.

Lúcio and Probius work very well together, as they both can siege an enemy base almost indefinitely. These two heroes complement each other very well in other ways too, as Lucio’s Speed Boost is great for getting Probius out of a pinch, and Probius makes up for Lucio’s lack of wave clear.

Effective against

Effective foes

Anub'arak can easily bypass Probius’ defenses and get to him with a well-timed Burrow Charge, and his Beetles are great for tanking Photon Cannon shots while Probius runs for his life. Anub’arak’s Heroics are also both great against Probius, as Locust Swarm naturally has more targets due to Pylons and Photon Cannons, and Cocoon is a great tool for isolating either Probius himself or one of his key frontline heroes, leaving him vulnerable for an easy kill.

Nothing is quite as frustrating for a Probius player than the constant loss of his Pylons. Li-Ming has enough range that she can easily kill Pylons almost as soon as they come up, and Probius doesn’t have a great answer to zone Li-Ming away due to her Teleport. She’s a difficult target to hit with Warp Rifts, and Probius’ low Health also makes him a prime kill target for a quick reset, which can dramatically swing the fight in Li-Ming’s favor.

Probius has trouble with heroes who can consistently get to him, and no one is quite as good at that as Zeratul. Zeratul has a plethora of ways to get to Probius, and he can often safely retreat if things go south once he engages. Both Shadow Assault and Void Prison are also great tools for catching and eliminating Probius if he is even a little out of position.

  • Alexstrasza's second Heroic Ability, Cleansing Flame, had its core concept originally meant for Probius, where he would summon a protoss mothership to bombard his enemies. The development team found that to contradict with his builder-oriented gameplay, and scrapped the idea. This was later moved to Alexstrasza instead.[3]
