Haunted Mines

2017-01-04 Patch Notes

Design & Gameplay

Armor & Vulnerability

Developer Comments: With today’s patch you will notice that a lot of our tooltips that used to reference the Resistant/Vulnerable system have been changed. Matthew Cooper detailed the changes on our forums last month explaining a bit about the new system. While the tooltips may have changed, the actual functionality for the system has been in since the Varian patch hit during the week of November 14, so the game itself should not feel any different than what you are currently used to. You will also notice that we have added baseline Armor to three Heroes – Arthas, Anub'arak, and Greymane’s Worgen Form. These are the first of a handful that we are planning to release and would love to hear any feedback you have. We are hoping that the Armor System will open up future design flexibility, increase the depth of strategy (both in game, and in draft), and grant us another knob to help balance the game.

Battleground Updates

  • Grave Golem
    • Attack Damage scaling for summoned Grave Golems has been increased at all stages of the game.

2016-12-14 Patch Notes

Battleground Updates

Battleground Rework

  • After driving the Raven Lord out of the Haunted Mines and doing a little. . . redecorating. . . the Grave Keeper has re-opened the Mines to all who wish to summon powerful and destructive Grave Golems.

Haunted Mines Basics

  • Venture Underground
    • The Haunted Mines will periodically open with an Undead Army underneath.
  • Collect the Skulls
    • Destroy the Undead and collect their Skulls to summon a powerful Golem. The more Skulls each team collects, the stronger their Golems become.
  • Unleash the Golems
    • After the Undead have been defeated, a Golem will rise for each team and travel down lane in search of Structures to destroy.

Haunted Mines Updates

  • Grave Golems now spawn in fixed positions in each lane, and switch lanes each time they are summoned.
  • The layout of the Underground Mines has been reworked, and the Neutral Grave Golem can now be found at its center.
  • The upper level’s center area has been reworked.
    • Additional Mine Entrances have been placed to the East and West of the Battleground’s center area, for a total of 4.
    • A Mercenary Camp has been placed near each Mine Entrance, featuring Siege Giants at the East and West Entrances, and Sappers in the North and South.

2016-11-22 Hotfix Patch

Bug Fixes

  • Minions: Catapult Minimap icons will now appear team-colored.

2016-11-15 Patch Notes

Bug Fixes

2016-09-13 Patch Notes

Design & Gameplay

Mounts

  • Movement Speed reduced from 40 to 30%

Regeneration Globes

  • Time before Globes despawn reduced from 8 to 6 seconds

Battlegrounds

Mercenaries

  • Timing Changes
    • Previously all Mercenary camps spawned at 120 seconds. The following adjustments have been made to spawn times:
      • 90 seconds: Sappers, Doubloon Pirates
      • 120 seconds: Siege Giants (unchanged), Impalers (unchanged)
      • 150 seconds: Knights, Fallen Shaman
      • 180 seconds: Grave Golem (unchanged)
      • 300 seconds: Headless Horseman (unchanged)
  • Captured Mercenaries will no longer grant Experience when killed.

Developer Comments: We started playtesting with staggered Mercenary Camp spawn times, and quickly began to realize that it added more strategic depth to the game, and coincided with some of our Battleground events. We have been happy with the changes overall, and are listening to any feedback you may have!

Bug Fixes

  • Heroes can no longer push captured Mercenaries by walking into them.

2016-08-09 Patch Notes

2016-07-27 Balance Update

Bug Fixes

  • Collision: Heroes can no longer be pushed by walking another Hero into them.
  • Collision: Heroes who are channeling an Ability can no longer be pushed when another Hero walks into them during the channel.

2016-07-12 Patch Notes

Design & Gameplay

Core

  • Victory determination is now much more precise in situations where both Cores are destroyed within fractions of a second. As a result, Victory will no longer be decided at random in cases where it appears that both Cores are destroyed at the same moment.

Regeneration Globes

  • Health Regeneration
    • Previously: Restore 6.24% of maximum Health over 4 seconds
    • Now: Restore 12% of maximum Health over 5 seconds
  • Mana Regeneration
    • Previously: Restore 32 Mana over 4 seconds.
    • Now: Restore 8% of maximum Mana over 5 seconds

Developer Comments: Thank you for all your discussion and feedback on our recent Health sustain post! We are still heavily evaluating a lot of it but wanted to get the first round of changes in. Internally, we enjoyed the increased importance on Regeneration Globes and have cleaned up the system a bit. With a larger importance, denying enemies their Globes in lane has a much larger impact.

Healing Wells

  • Cooldown increased from 100 to 120 seconds
  • Health Regeneration
    • Previously: Restore 41% of maximum Health over 20 seconds.
    • Now: Restore 40% of maximum Health over 20 seconds.
  • Mana Regeneration
    • Previously: Restore 20% of maximum Mana over 20 seconds.
    • Now: Restore 30% of maximum Mana over 20 seconds.

Developer Comments: Much like the changes to Regeneration Globes, we wanted to add a larger impact to the moment you click a Healing Well. Again, we cleaned up the system a fair bit (hence the ~41% to 40% Health change) and added a larger impact for heavy Mana users. The increased cooldown should make the decision of when to tap the Healing Well slightly more interesting.

Minions

  • Ranged, Melee, and Wizard Minions
    • Now deal an additional 50% damage to Structures.

Developer Comments: Our goal with this change is to make escorting Minions to Towns to be more impactful, such that they can really start to do some damage if left unattended. Before this change, Minions were primarily XP carriers that absorbed some Ammo shots from Towers. Now the armies of the Nexus are a bit scarier when they march down a lane.

  • Catapult Minions
    • Attack range increased by 20%.
    • Sight range increased by 17%.
    • Will now fixate on Structures. Catapults will not acquire a new target after fixating until the target is destroyed or the Catapult is killed.

Developer Comments: Catapults would often reach the Core, but have a Minion wave spawn on them, distract them, and allow them to be killed off before doing any significant damage. With increased range and fixation on a Structure once they’ve started attacking, even one Catapult will more consistently punch through a Core’s Shield and do actual damage.


2016-05-17 Patch Notes

Battlegrounds

Healing Well

  • 25% of a Healing Well’s maximum Health has been converted into a Shield. Shield Regeneration delay of 8 seconds.

Developer Comments: We’ve noticed some rather un-fun behavior in the form of sniping Healing Wells over time using very long range Abilities. While we’re okay with players doing this to a degree, we found it was too effective given how little counterplay there was. To help solve this, turned a sizable portion of Healing Well Health into a Shield. This means that if you offer your Healing Well some respite from enemy attacks by chasing opponents away every now and then, it will start to regenerate some of that Shield. Only you can protect Healing Wells from those pesky Arcane Orbs!

Bug Fixes

  • Fixed an issue in which attacking enemy Walls at certain angles would cause the Hero’s Basic Attack animation to play, but deal no damage.

2016-04-27 Balance Update

Bug Fixes

  • Issuing a Mount command while holding down the right mouse button to move will no longer interrupt Mount channeling.

2016-04-19 Patch Notes

2016-02-10 Balance Update

Bug Fixes

  • Dying will no longer cause the player’s Healing Well cooldown to reset.

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.)

Battlegrounds

Structures

  • Towers, Forts, and Keeps now deal 50% bonus damage to Heroes
  • Cores will now display an “Invulnerable” message if attacked by an enemy when no allied Keeps have been destroyed.
  • Structures can no longer be made Vulnerable

Developer Comments: The scaling changes we released in December made it so Heroes could dive into Structures with impunity during the early game. Increasing the damage that Structures deal to Heroes allows defending players to feel a bit safer. We are exploring other fixes to help Structures feel more meaningful throughout the game and will release them when they are ready.

Bug Fixes

  • Diagonally placed shrubs will now properly hide Heroes within them.
  • Players punted out of an enemy Hall of Storms will no longer be persistently stunned if an enemy unit blocked the path of the punt.

2015-12-15 Patch Notes

Bug Fixes

  • Diagonally placed Shrubs will no longer sometimes fail to properly hide a Hero within.

2015-11-17 Patch Notes

Design & Gameplay

Scaling Changes

  • Health and damage scaling for all Heroes, Battleground Events, Minions, and Mercenaries has been changed from flat, additive values to values that are multiplicative by percentage.
  • A large portion of Heroes’ total scaling amounts, which were previously gained over the course of a game, have been added to their base values.

Developer Comments: Due to the way that our old level scaling system worked, early game level discrepancies created a larger difference in power level than we liked. This often led to situations where a team could be up two or more levels early in a game, and use this advantage to create a larger lead. We didn’t feel that games were fun for the winning or losing team in these types of scenarios. As a result of these changes, all Heroes will have more power early, but gain less from each level. Battleground Events, Minions, Mercenaries, and Structures have all been adjusted to compensate for this and should feel close to what they did previously. The aim of these adjustments to the scaling system is to make level differences have a similar impact on your Hero’s statistics at all points in a game. Now, each level offers about 4% Health and 4% damage, which mirrors what late game leads felt like in our previous version of the game. It is important to note, that while being down a few levels will be less punishing than it was previously, Talent tier advantages can and will still have a noticeable impact on enemy engagements.

Respawn Timers

Developer Comments: In order to reward players for getting early game Takedowns, we’re also increasing the respawn time of dead Heroes at low levels. Now, getting early game Takedowns (and the experience associated with it) won’t give your team as much pure power as it did previously. Instead, early kills will offer a “power play” moment, in which your team can destroy enemy Structures, complete Battleground Events, or take more Mercenaries. These meaningful strategic advantages will position a team closer to victory, without giving them a large stat advantage and the ability to bully the opposing enemy team.

Attack Speed Slows

  • Attack speed slows now apply only to Heroes and Summons.

Battleground Updates

  • This Battleground has been removed from all matchmaking queues for the foreseeable future, but is still playable in Custom Games

Developer Comments: We’ll be adding Towers of Doom to the map pool in an upcoming patch. This will expand the size of our map pool to 10 total Battlegrounds. To prevent the number of maps we have available to players in Quick Match and Hero League from being overbearing, we’ve decided to temporarily rotate out Haunted Mines. We feel the number of maps we have available are reaching a threshold that we may not be comfortable with.


2015-10-06 Patch Notes

Design & Gameplay

A.I. Talent Selection

  • A.I. controlled Heroes will now select their Talents from a group of preset Talent builds.

Developer Comments: A.I. players will now choose from predetermined Talent builds instead of randomly selecting Talents. This is especially important for players who disconnect as the A.I. will now no longer randomly choose Talents, but instead try to pick builds that are closer to what players would expect. In addition, A.I. controlled Heroes in Versus A.I. games will also have their own Talent builds to choose from.

Vehicles and Regeneration Globe Interaction

  • Regeneration Globes will no longer heal Dragon Knights and Garden Terrors.
    • Instead, Regeneration Globe effects will now be applied directly to the Hero inside the Dragon Knight or Garden Terror.
  • Players within a Dragon Knight or Garden Terror can now also accumulate stacks for Talents such as Seasoned Marksman, Gathering Power, Regeneration Master, etc.

Summoned Unit Attacks

  • Summoned unit Basic Attacks will now miss if that Summon is Blinded or the target is Evading.

2015-05-12 Patch Notes

Bug Fixes

  • Alerts proclaiming that the Core is under attack will no longer play when an enemy Hero is within range of the Core before a Keep has been destroyed.
  • Fixed an issue that could cause the neutral Grave Golem in the Haunted Mines to drop Skulls outside the playable area.
  • Players will no longer enter an infinite rejoin loop if both Cores are destroyed simultaneously, and victory will be assigned to one team at random.
    • Please note: Randomly assigned victory/defeat is intended as a temporary solution, intended to fix the infinite rejoin loop as soon as possible. A more robust solution for games that end in a draw will be implemented with a future patch.

2015-03-24 Patch Notes

    • The Haunted Mines have been open for at least 4 minutes
