Developer Comments: As part of our ongoing process to improve our talent system, we are doing a pass on all heroes in the game to increase the health of their talent trees. We know that there are a fair number of talents that feel like they are either mandatory or insignificant, and this is our first pass on putting in fixes. These fixes take many forms, and can range from simply buffing or nerfing numbers to changing functionality. We’re excited to keep our heroes feeling fresh, and you can look forward to additional changes to more of our heroes in upcoming patches.

Bug Fixes

  • Falstad: Will no longer be struck by ground-level objects, such as Abathur’s Toxic Nests, while using Flight.
  • Infernal Shrines: Punishers will no longer prefer to attack non-Heroic enemies that are affected by Abathur’s Symbiote over enemy Heroes.

2016-05-17 Patch Notes

Bug Fixes

  • Fixed an issue that could cause Abathur and Gall players to be flagged as AFK if they did not move from the starting area, despite issuing commands to their Heroes.

2016-04-12 Balance Update

Hero Updates

  • Evolve Monstrosity (R)
    • Maximum Minion stacks increased from 30 to 40.
    • Health increased from 931 (+4% per level) to 1000 (+4% per level).

Developer Comments: We want to make some basic improvements to a lot of the lesser-picked/lower win-rate Heroic Abilities. Most of these are pretty simple changes to make them more enticing, like adding more damage, reducing cooldowns, or lowering Mana costs. We realize that the primary use case for Abilities like Li Li’s Water Dragon or E.T.C.’s Stage Dive is not damage, but having more of it might help them feel more effective. We’re trying to do something a little bit different with Brightwing’s Emerald Wind and Malfurion’s Twilight Dream by compensating for some of the Support capability you miss out on by picking these Heroics. We’re excited to see how these go! In Thrall’s case, Sundering was a little too strong, so we’re reducing its stun duration.


2016-03-29 Patch Notes

Hero Updates

  • Ultimate Evolution (R)
    • Will now inherit Kharazim's Trait

2016-03-09 Balance Update

Hero Updates

  • Symbiote (Q)
    • Carapace (E)
      • Shield amount increased from 137 (+4% per level) to 150 (+4% per level)
  • Toxic Nest (W)
    • Vile Nest (Talent)
      • Slow amount decreased from 50% to 40%
      • Slow duration reduced from 4 to 3 seconds

Developer Comments: It’s extremely difficult bartering with a space slug. Abathur refuses to allow us to nerf devolve him without also buffing evolving him. In exchange for lowering the overbearing slow amount and duration of Vile Nest, he has gladly accepted a baseline increase to his Carapace Shielding.

Bug Fixes

  • Abathur players will no longer become locked out of casting Abilities if Symbiote is cast at the same moment that Abathur is killed.

2016-03-01 Patch Notes

Bug Fixes

  • Towers will now properly fire Ammo provided by an allied Calldown: MULE immediately after 2 Ammo has been restored.

      • Damage increased from 106 (+4% per level) to 111 (+4% per level)

2015-10-14 Hotfix Patch

Bug Fixes

2015-10-06 Patch Notes

Hero Updates

  • Locust Strain (Trait)
    • Locusts will no longer spawn as soon as the game begins, and will now wait until the first Minion wave spawns
  • Evolve Monstrosity (R)
    • Pressing R with a Monstrosity active will now automatically cast Symbiote on the Monstrosity and move your camera to its position

Developer Comments: Abathur’s initial Locust would previously sit idle until Minions spawned. This change will allow Abathur to get in position before the first Locust spawns at the start of a game.

Bug Fixes

  • A Sgt. Hammer clone created by Abathur’s Ultimate Evolution will no longer be granted the Napalm Strike Heroic Ability after entering Siege Mode.
  • Abathur will no longer receive Takedown credit after casting Symbiote on an allied Leoric that is then killed by the enemy team.
  • Abathur will now properly receive Takedown credit after dealing the killing blow to Leoric.
  • Abathur's Hivemind Symbiote will no longer persist on Leoric after he enters Undying form.
  • The Butcher will no longer stop his Ruthless Onslaught charge if Abathur's Ultimate Evolution clone charges the target first.

2015-09-08 Patch Notes

Bug Fixes

  • Abathur’s Toxic Nests will no longer provide larger than intended areas of vision.

2015-08-18 Patch Notes

Design & Gameplay

Ability Power Gains

Developer Comments: This change was aimed at removing odd gameplay where a Nazeebo player may actually want to sacrifice his or her Gargantuan for a more powerful one. This occurred if players kept a summon alive for a very long time and gained Ability Power via Talents, like Gathering Power, as this increase in Ability Power was not passed onto the Summon. Short term summons or persistent effects will still take a snapshot of your current Ability Power at the time they are cast, and apply the bonus for the complete duration of the effect.

  • To clarify the rules for temporary Ability Power gains, the following rules have been added:
    • For permanent or very long duration pets or persistent effects, their damage and maximum Health will now update dynamically when Ability Power is modified. This includes:
      • Abathur's Monstrosity
      • Nazeebo's Gargantuan (with the Humongoid Talent)
    • For short duration pets or persistent effects, their damage and maximum Health should snapshot based upon the Ability Power of the character when they are cast. This includes:
      • Jaina's Water Elemental
      • Sgt. Hammer's Blunt Force Gun
      • Tychus' Drakken Laser Drill

Hero Updates

Developer Comments: We’ve tuned up some of his weaker talent picks to make them more viable. We really like the level 20 Hivemind talent, but it can feel clunky to use as when allies move out of range, you have to decide whether to cancel and recast it, or stay focused on only a single target. With these changes, Hivemind will be much more fluid to play with and consistent in its effectiveness.

  • Volatile Mutation (Talent)
    • Damage increased from 36 (+7 per level) to 50 (+10 per level)
    • Damage radius increased by 20%
  • Locust Strain (Trait)
    • Survival Instincts (Talent)
      • Locust Health bonus increased from 30% to 50%
  • Symbiote (Q)
    • Carapace (E)
      • Regenerative Microbes (Talent)
        • Healing per second increased from 7 (+2 per level) to 9 (+3 per level)
    • Hivemind (Talent)
      • Now searches for a new Hivemind target every second, rather than only on the first cast
      • The secondary Symbiote target’s Stab and Spike Burst deal half their normal damage, and Carapace grants half its normal Shield amount
  • Toxic Nest (W)
    • Cooldown reduced from 12 to 10 seconds
    • Envenomed Nest (Talent)
      • Bonus damage increased from 50% to 75%

Bug Fixes

  • Abathur’s Evolve Monstrosity cooldown will no longer begin counting down when Abathur is killed while a Monstrosity remains alive.
  • Abathur’s Stab and Spike Burst Abilities will now deal the proper amount of damage to Promoted Minions.
  • After learning the Evolution Complete Talent, Abathur’s Monstrosity will no longer retain some of the Minions Absorbed stacks earned by a previous Monstrosity.
  • Casting Abathur’s Ultimate Evolution on Tyrael just as Tyrael is killed will now properly place Ultimate Evolution on a reduced cooldown.
  • Fixed an issue that could allow Abathur to become permanently invulnerable under certain circumstances.

2015-07-08 Hotfix Patch

Bug Fixes

  • Abathur will no longer receive the death overlay, nor be automatically teleported back to the allied Hall of Storms, after an Ultimate Evolution Murky clone is killed.

2015-06-30 Patch Notes

Hero Updates

  • Symbiote (Q)
    • Carapace (E)
      • Networked Carapace (Talent)
        • Carapace now always Shields nearby Minions and Mercenaries, regardless of Symbiote’s target

Bug Fixes

  • Abathur's Toxic Nests once again display activation and expiration timers.
  • Uther’s Holy Radiance will now properly damage Abathur’s Toxic Nests and Zagara’s Creep Tumors.

2015-05-12 Patch Notes

Hero Updates

  • Locust Strain (Trait)
    • Bombard Locusts (Talent)
      • Bombard Strain Locust attack range reduced by 30%

    • Envenomed Nest (Talent)
      • Damage increased from 30% to 50%

      • Now also reduces the cooldown of Toxic Nest by 2 seconds
    • Vile Nest (Talent)
      • Slow increased from 40% to 50%
  • Evolve Monstrosity (R)
    • The Monstrosity now persists until it is killed.

2015-02-10 Patch Notes

Design & Gameplay

Bug Fixes

  • Fixed an issue in which Abathur could become permanently stuck in Symbiote form under very specific circumstances.
  • Players will no longer permanently lose control of Abathur if he is killed immediately after the Ultimate Evolution Heroic Ability expires (Hotfixed on January 22).

2015-01-13 Patch Notes

  • If two Structures with equal priority are in range of the MULE’s placement, it will begin repairing the one it was dropped closer to.
