Developer Comments: It's been nice to see the positive reactions to the Lord of Terror's recent changes. That said, the latest rework gave him some new survivability talents that are slightly over-performing. The new stacking Resistant system is making the interaction between Shadow Charge, Bulwark and Soul Shield a bit too strong, so we are making some adjustments to compensate.

Developer Comments: The Lord of Terror has been under the knife for a couple months and has finally collected enough souls to resurrect himself. He reenters the Nexus with an updated talent tree focusing on maintaining and amplifying his identity. He should still excel as a gank-oriented Warrior, punishing out-of-position enemies, but also brings along some new survivability options. While we had to lower his damage slightly, the baseline addition of Firestorm and larger payoff for Shadow Charging enemies into collision should heavily reward opportunistic Diablo players.

2016-09-27 Patch Notes

Bug Fixes

  • Diablo: It is no longer possible to cast Overpower on Heroic Vehicles, such as the Garden Terror or Dragon Knight.

2016-09-13 Patch Notes

Talents

Imposing Presence (Active)

  • New functionality:
    • Heroes that attack you have their Attack Speed slowed by 20% for 2.5 seconds
    • Activate to Slow the Attack Speed of nearby Heroes and Summons by 50% and Slow their Movement Speed by 20% for 2.5 seconds

Developer Comments: We did not like the power of the Attack Speed slow for Imposing Presence given how little counter-play there is. We’ve decided to move some power out of the passive portion of the Talent and give it a new activated effect in order to create some bigger moments for players who choose to take it.

Spell Shield (Passive)

  • Added functionality:
    • Spell Shield can now be toggled on or off to allow for better control of which Abilities you want to mitigate

Hero Updates

Talents

  • Level 7
    • Devastating Charge (Q)
      • New functionality:
        • Shadow Charge grants Resistant, reducing all damage taken by 25% for 4 seconds.

Developer Comments: We’re removing the majority of our old Relentless- like Talents from the game, because we found that it wasn’t clear to the enemy team what was happening. Reducing the duration on very short disabling effects to begin with was hard to notice, and typically felt like a bug when it did happen. In some cases, we’re replacing these Talents with Hero specific ones that more clearly convey what’s happening, while fitting the gameplay of the Hero.

Bug Fixes

  • Diablo: Apocalypse will now correctly target enemies trapped by Anub'arak’s Cocoon.
  • Diablo: Overpower’s target will no longer be stunned for the Ability’s full duration if Diablo is interrupted by a knockback at the same time Overpower is cast.

2016-07-27 Balance Update

Bug Fixes

  • Greymane: Will no longer become stuck if Darkflight is interrupted by Diablo’s Shadow Charge or Stitches’ Hook.

2016-07-12 Patch Notes

Talents

Relentless

  • Relentless and similar Hero-specific Talents will now only reduce the duration of Slows, Stuns and Roots. Silence effects will no longer be reduced by this talent.

Developer Comments: With an increasing number of CC effects entering the Nexus we found ourselves constantly asking ourselves “Should Relentless work against this?” which quickly turned into a rabbit hole of ‘what-ifs’ and ‘how comes’. We agreed that the talent was going to continue to become stronger as we moved forward and decided to limit the number of effects that it can reduce.


2016-05-19 Hotfix Patch

Bug Fixes

  • Fixed an issue in which Diablo’s Shadow Charge could Stun Unstoppable targets in certain circumstances.

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.

Hero Updates

  • Shadow Charge (Q)
    • The implementation for this Ability has been reworked.
      • No longer automatically Stuns the target at the end of the knockback phase, and instead applies a Daze for the duration of the knockback.
        • Targets that collide with terrain will still be stunned for 1 second.
      • Diablo will now continue travelling toward the enemy target for the duration of the knockback phase.
  • Apocalypse (R)
    • Stun duration reduced from 2 to 1.75 seconds.

Developer Comments: Shadow Charge seems like a really simple Ability, but on the backend there were a lot of technical manipulations to make everything work the way they were intended. These were starting to create odd gameplay and bugs, so we’ve simplified the design of the Ability so that Diablo travels right alongside his victim as they are knocked back, instead of walking really fast toward them.

Additionally, we’ve received a lot of feedback from players regarding the popular strategy of chaining movement impairing effects, like Stuns and Roots, on an enemy Hero. While we want this to be a viable way to play, we feel it’s currently too prominent and powerful at higher levels of play. As a result, we are reducing the duration of many of these effects in the game. In scenarios where this change nerfs a character we don’t otherwise want to nerf, we’re coupling it with a buff to help offset the difference. While this change hasn’t reduced all effects that might make you lose control of your Hero, we feel these are some of the more egregious ones. As always, we will make further changes if necessary.


2016-03-29 Patch Notes

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%.


2016-02-10 Balance Update

Hero Updates

  • Fire Stomp (W)
    • Fire Devil (Talent)
      • Damage reduced from 23 (+4% per level) to 17 (+4% per level)

Developer Comments: Diablo has hovered near the top of our win rate charts for a while. We wanted to see how the Tyrande nerfs would impact him first, as we know those characters have very strong synergy together. We haven’t seen much of a dip in Diablo’s win rate, so we’re targeting a ‘must pick’ Talent with this nerf.


2016-02-02 Patch Notes

Design & Gameplay

Battleground Monsters

  • Battleground-specific creatures are now universally defined as Monsters (ex: Neutral Garden Terrors, Sky Temple Guardians, etc.)
  • Several Talents and Abilities have been changed to reflect this new categorization, and the following no longer affect Monsters:
    • Mercenary Lord
    • Johanna's Knight Takes Pawn
    • Lunara's Cruel Bloom
    • Rexxar's Easy Prey and Bird of Prey
    • The Butcher's Chop Meat
  • The following now affect Monsters:
    • Anub'arak's Beetle, Juiced
    • Azmodan's Demonic Smite
  • Several Talents that could previously trigger against both captured Mercenaries and Minions will now only affect Minions (ex: Seasoned Marksman, Black Soulstone, etc.)

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

  • 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.

  • Black Soulstone (Trait)
    • Maximum Health gained per Soul increased from 0.15% to 0.2%
    • Essence of the Slain (Talent)
      • Now also grants 10 Health for each enemy slain nearby
  • Shadow Charge (Q)
    • Range increased by approximately 15%
    • Stun duration after knocking an enemy into a wall increased from 0.75 to 1 second
    • Devastating Charge (Talent)
      • Now reduces movement impairing effects for 6 seconds, up from 3 seconds
  • Fire Stomp (W)
    • Damage increased from 30 (+9 per level) to 33 (+10 per level)
    • Mana cost decreased from 50 to 40
  • Overpower (E)
    • Domination (Talent)
      • Cooldown reduction for Shadow Charge increased from 8 to 10 seconds

Developer Comments: The buffs to Shadow Charge should help to reinforce Diablo as the premier gank Warrior. The rest of his kit gets a little bit of love to help his overall play.


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

Imposing Presence

Developer Comments: Statistically, it was almost never wrong to choose Imposing Presence. With this nerf, it’s still a great counter in the right situation, and as a result, we’re hoping we’ll see more play from our Basic Attack assassins.

  • Attack Speed slow reduced from 50% to 40%
  • The Attack Speed slow will now be removed when attacking a target that has not learned the Imposing Presence Talent

Bug Fixes

  • Fixed an issue in which the following Abilities and Talents were not damaging or destroying Zagara's Creep Tumors:

2015-07-02 Hotfix Patch

  • Resolved an additional issue that could cause Heroes affected by Diablo’s Overpower to fly outside the Battleground’s playable area.

2015-06-30 Patch Notes

Talents

  • Duration increased from 2 to 3 seconds

Bug Fixes

  • Diablo’s Fire Stomp can now properly damage and reveal Zagara’s Creep Tumors.
  • Fixed several issues affecting Diablo’s Overpower Ability that could cause Heroes to fly out of the Battleground's playable area.
  • Using Diablo’s Shadow Charge on Raynor’s Banshees near the edge of a Battleground will no longer cause Diablo to leave the playable area.
