2021-01-19 Balance Update

Hero Updates

Talents

  • Level 7
    • Queen of Blades [Q]
      • Damage bonus increased from 50% to 100%.
      • Ravage cooldown reduction increased from 2 to 3 seconds.

Developer Comment: We were too scared of Queen of Blades being too powerful when we redesigned the talent, so we're tuning it up to better match our original vision. This should enable her to clear waves much more efficiently while also allowing her Ravage to be up much more often.

2020-10-07 Balance Update

Hero Updates

Talents

  • Level 1
    • Siphoning Impact [Q]
      • Shield amount increased from 90 to 100.
    • Assimilation Mastery [Trait]
      • Shields granted increased from 45 to 50.
  • Level 4
    • Psionic Pulse [E]
      • Second explosion time reduced from 2.5 to 2 seconds.
  • Level 7
    • Queen of Blades [Q]
      • New functionality: Reduce the cooldown of Ravage by 2 seconds and increase its damage to Minions and Mercenaries by 50%.

      • Additional functionality: Increase the Health and Attack damage of Ultralisk by 20%.

Developer Comment: Kerrigan's talent tiers generally have one talent that most people are using, followed by the other two talents on the tier having decent parity. We're giving some buffs to her alternate talents to become more attractive choices, which should allow for more diverse ways to play her.

2020-04-14 Patch Notes

Bug Fixes

2020-03-11 Balance Update

Hero Updates

Talents

  • Level 13
    • Psionic Barrier [E]
      • Additional functionality: Hitting an enemy Hero with Primal Grasp also grants Kerrigan 4% Movement Speed for 4 seconds, stacking up to 20%.
    • Chrysalis [Active]
      • Chrysalis is now able to be cancelled early.

Developer Comment: We've heard feedback from Kerrigan players for some time that they would like to have the ability to cancel Chrysalis early. We originally intended it to be this way to separate it a bit from other similar mechanics and to give opponents a reliable way to counter it, but found that it ended up being less fun and interesting overall. Because of this, we're adding the ability for Kerrigan to cancel the effect early.

      • Bonus duration per tick increased from .125 to .1875

​Developer Comment: Kerrigan has one build that is particularly powerful at the moment, and these changes aim to bring her back in line with the rest of the cast. We've also made a change to her baseline Assimilation to revert it to it's previous levels, as her overall survivability is a little higher than desired from a melee assassin.

Developer Comment: Kerrigan is receiving an update to increase the tactical depth of using her abilities and increase the impact that her Talents have on her playstyle. We've reduced the range on Ravage but added a second charge so that smart Kerrigan players can use it to maneuver on the battlefield, as well as utilize a lot of her Talents to get the most out of the ability. We've added a secondary explosion to Primal Grasp so that Kerrigan will want to continue to worry about her positioning after her initial engagement occurs, as well as provide the opportunity for new Talent interactions. We've also added a skillshot component to Ultralisk so that the Heroic can feel like it has a big moment when it is first unleashed. Overall, Kerrigan should play mostly the same, but have increased room for mastery and playstyle specific builds.

2017-11-01 Balance Update

Bug Fixes

  • Kerrigan: Triggering the Double Strike Talent after learning Fury of the Storm will no longer cause the next Basic Attack to deal more than the intended amount of cleave damage to secondary targets.

Developer Comment: Kerrigan’s win-rate has been at a steady 1-2% climb each patch for the last few months. While she is not demanding picks or bans at the moment, as of last week she was sitting on top of the Nexus. After closely analyzing her numbers, there was nothing standing out as a major reason for her climb upwards. So instead of doing anything massive, we felt it best to do a slight damage redistribution. Moving a small percentage of her Ravage damage into her other abilities will help with some talent pick/win rate issues while also bolstering her skill-shot abilities.

    • Cooldown now also counts down while the Ultralisk is alive

Bug Fixes

  • Kerrigan: Fixed an issue in which Essence for Essence would always follow the player’s global Quick Cast settings.

2016-10-18 Patch Notes

Bug Fixes

  • Damage Reduction: When two damage reduction effects, such as Resistant (25%) and Hardened Shield (75%), are simultaneously applied to a Hero, the larger effect will no longer be overridden by the lesser effect.
  • Kharazim: Will no longer automatically resume attacking enemies after using Radiant Dash to dive to an ally. This fix also applies to Illidan’s Friend or Foe and Kerrigan’s Adaptation Talents.

2016-09-13 Patch Notes

    • Damage per pulse decreased from 41 to 37

  • Level 4
    • Psionic Pulse (E)
      • Damage per pulse decreased from 20 to 18

Developer Comments: We are trying to be very careful with changes to Kerrigan, as we are excited to see her return to the spotlight. She is not too far off, but we wanted to lower her area-of-effect damage just a tiny bit.

Bug Fixes

  • Kerrigan: Assimilation will now properly grant Shields for splash damage dealt by Kerrigan’s Basic Attacks after learning Fury of the Swarm.

2016-07-27 Balance Update

Hero Updates

Stats

  • Base Health decreased from 1848 to 1680
  • Base Health Regeneration decreased from 3.95 to 3.64 per second

      • Damage reduced from 24 to 20 per pulse
  • Level 7
    • Bladed Momentum (Passive)
      • Cooldown reduction per Basic Attack reduced from .75 to .6

Developer Comments: Our recent changes to the Queen of Blades had a much larger impact than we were expecting. Since her damage directly fuels her survivability, we feel like the additional Health increase pushed her a bit too far. We love that she feels more aggressive now and are happy to see her back in the mix of contested Heroes. By reverting her Health buffs and targeting a few over-performing talents we expect to see her come back in line.

2016-07-12 Patch Notes

    • Blade Torrent (W)
      • Moved to Level 7

Developer Comments: Kerrigan definitely has her place as a niche pick on a few Battlegrounds. While her win-rate is fairly healthy, she has become a bit of a one-trick-pony. We feel this is okay for some Heroes and makes for interesting draft implications, but we knew we wanted to make some tweaks to help even her out. We increased her base stats in order to offset the added restrictions we applied to her Ravage, and overall did a large number of tweaks to help level out her whole Talent Tree.

2016-05-17 Patch Notes

Talents

Battle Momentum

  • Battle Momentum has been made Hero-specific, and now only applies to Basic Ability cooldowns.
  • Diablo
    • Diabolical Momentum
      • Basic Attacks now reduce Basic Ability cooldowns by 0.75 seconds instead of 0.5.
      • No longer reduces Heroic Ability cooldowns.
  • Johanna
    • Blessed Momentum
      • No longer reduces Heroic Ability cooldowns.
  • Kerrigan
    • Bladed Momentum
      • Basic Attacks now reduce Basic Ability cooldowns by 0.75 seconds instead of 0.5.
      • No longer reduces Heroic Ability cooldowns.
  • Tyrael
    • Angelic Momentum
      • Basic Attacks now reduce Basic Ability cooldowns by 0.75 seconds instead of 0.5.
      • No longer reduces Heroic Ability cooldowns.
  • Tyrande
    • Lunar Momentum
      • Basic Attacks now reduce Basic Ability cooldowns by 0.6 seconds instead of 0.5.
      • No longer reduces Heroic Ability cooldowns.
  • Zagara
    • Swarm Momentum
      • Basic Attacks now reduce Basic Ability cooldowns by 0.75 seconds instead of 0.5.
      • No longer reduces Heroic Ability or Trait cooldowns.

Developer Comments: Our intention for Battle Momentum was to create more active gameplay by using your Basic Abilities more often, but we found that a lot of this Talent’s power lied in its ability to reduce your Heroic cooldowns. We wanted to increase the cooldown reduction granted by the Talent, but didn’t want Heroic Ability cooldowns to drop to absurdly low levels. By making it only reduce the cooldowns of Basic Abilities (Q, W, E), it allowed us to increase this cooldown reduction without making it overpowered. We’ve also made Battle Momentum Hero-specific, so that we can tune each one without affecting all the rest, since Attack Speed, melee versus range, and the nature of your Basic Abilities can all drastically change what is balanced.

Developer Comments: We are hearing your feedback about Kerrigan.

Although we don’t currently have any extensive changes planned for her, she is definitely on our radar and you can expect to see some more tweaks coming soon™.

2016-03-29 Patch Notes

Design & Gameplay

Hero Movement Interaction Unification

  • Several Abilities have been changed in an effort to unify their usage.
    • The following Abilities can now be used to move to invulnerable units:
      • Kerrigan — Ravage (Q)
      • Illidan — Dive (Q)
    • The following Abilities can now be used to travel to objects created by an enemy, such as Sgt. Hammer’s Spider Mines:
      • Kerrigan — Ravage (Q)
      • Lunara — Leaping Strike (R)
      • Illidan — Dive (Q)
      • Kharazim — Radiant Dash (Q)
      • Chen — Flying Kick (Q)

Talents

Block

  • Damage reduction increased from 50% to 75%

Developer Comments: We want to improve counter-pick talents like Block that are meant to be strong against certain hero types. We’re hoping that these kinds of Talents will have a more meaningful impact in games in which they are picked, and that there are more situations where the enemy team’s composition drives intelligent Talent choices.

Other effects similar to Block have been evaluated on a case-by-case basis for all Heroes, with some gaining increased Block damage reduction, while others stayed at 50%.

Hero Updates

  • Summon Ultralisk (R)
    • Attack damage increased from 91 (+4% per level) to 100 (+4% per level)
    • Torrasque (Talent)
      • Egg timed life decreased from 8 to 4 seconds
      • Egg Health decreased from 1095 (+4% per level) to 594 (+4% per level)

2016-02-02 Patch Notes

Design & Gameplay

General

  • Damage dealt by splash and cleave attacks will no longer trigger effects that would otherwise require a direct attack to trigger (ex: Block, Spell Shield, Imposing Presence, etc.)

Talents

Block

  • Block charges are now tracked in the buff bar next to the Hero portrait, and a timer has been added to show the time remaining until a new charge is generated.

2015-11-17 Patch Notes

Bug Fixes

  • The cooldown for Kerrigan’s Ravage will now be properly reset when it is used to destroy an enemy Structure.

2015-10-06 Patch Notes

Design & Gameplay

  • Summoned unit Basic Attacks will now miss if that Summon is Blinded or the target is Evading.
  • Summoned unit Basic Attacks will no longer consume Block Talent stacks.

Bug Fixes

  • Kerrigan will no longer receive multiplicative bonuses to Shield generation after learning the Aggressive Defense and Omegastorm Talents.

2015-08-18 Patch Notes

Talents

Bolt of the Storm

Developer Comments: We love this talent and think it can create a lot of really interesting moments, but the cooldown was just too short. At 70 seconds we think this talent is still a great level 20 pick, but now players will have to be more strategic with how they use it. Forcing someone to use their Bolt to avoid a gank can now be a meaningful moment with this increased cooldown. We hope this also entices players towards choosing their Heroic upgrades instead of Bolt when the situation calls for it.

  • Cooldown increased from 40 to 70 seconds

Hero Updates

Developer Comments: These changes are intended as a slight buff overall, and to provide Kerrigan with more options. Her level 1 range increase talent was almost always picked, so we made that baseline. Several new talents and mana alterations should allow Kerrigan players to try out some Ravage and Trait based builds.

Bug Fixes

  • Fixed an issue in which certain movement-based Abilities, such as Kerrigan’s Ravage or Chen’s Flying Kick, could not target the Doubloon Chests on Blackheart’s Bay, or Plant Terror Overgrowths on Garden of Terror.
  • Kerrigan's Aggressive Defense Talent now correctly increases the Assimilation Shield amount gained from Basic Attacks and Abilities by 100% when paired with her Fury of the Swarm Talent.

2015-06-30 Patch Notes
