Developer Comment: Our resident warlock has been in and out of the meta a couple times since his epic release and his Talent tree has become a bit lopsided. We began these changes by looking at Rain of Destruction (even going as far as testing the Ability without a channel!) but quickly realized that we would need more than just a balance patch to appropriately address the Heroic. We were, however, able to make some Talent adjustments that will hopefully give players fun new ways to drain the life from their opponents!


2018-03-30 Hotfix Patch

  • Fenix: Purification Salvo’s visual and sound effects will no longer continue to play if the Ability is cancelled due to its target becoming invalid, such as when Gul'dan casts Demonic Circle to teleport far beyond Purification Salvo’s range.

2016-09-27 Patch Notes

Hero Updates

Abilities

  • Life Tap (Trait)
    • Base self-inflicted damage decreased from 234 to 222
  • Fel Flame (Q)
    • Increased base size by 5%
  • Drain Life (W)
    • Base healing increased from 43 to 47
  • Corruption (E)
    • Cooldown reduced from 16 to 14 seconds
    • Mana cost reduced from 90 to 80

Talents

  • Level 1
    • Echoed Corruption (E)
      • Quest completion requirement increased from 35 to 40 Heroes hit by Corruption
  • Level 4
    • Health Funnel (W)
      • Cooldown reduction gained when an enemy dies under the effects of Drain Life changed from 7 seconds to a full cooldown reset

Developer Comments: Gul’dan’s slightly underperforming compared to other assassins, so we’re giving him some throughput buffs as well as buffing his Fel Flame ability. We know that the Echoed Corruption change may not be positively received as it is a slight nerf, but we believe it is better for the health of his talent tier and for him overall. The intent of this talent was for it to be a relatively large power spike but for it to come very late into the game. Currently it’s still being unlocked earlier than we would like, and it has a slightly higher win rate compared to other talents on the tier. We wanted to buff Corruption by lowering its cooldown, so we felt that it was appropriate to slightly increase its quest completion time to help balance it out.


2016-09-13 Patch Notes

Bug Fixes

  • Gul'dan: Learning the Health Funnel Talent and using Drain Life to kill a Hero with a post-death effect, such as Uther, will now properly reduce Drain Life’s cooldown.

2016-08-24 Balance Update

Hero Updates

Talents

  • Level 1
    • Echoed Corruption (E)
      • Number of hits required to complete quest increased from 30 to 35
  • Level 7
    • Curse of Exhaustion (E)
      • Slow duration increased from 2 to 2.5 seconds
  • Level 13
    • Fel Armor (Q)
      • Ability damage reduction increased from 30 to 40%
  • Level 16
    • Rampant Hellfire (Q)
      • Damage bonus increased from 6% per stack (30% max) to 8% per stack (40% max)
    • Darkness Within (Trait)
      • Damage bonus increased from 20 to 25%

Developer Comments: While he has an acceptable win rate in the hands of experienced players, we felt that Gul'dan could use a few minor buffs and talent tweaks to help make his talent tiers more competitive. His Echo of Corruption quest ended up being completed earlier than we intended for such a strong effect, so we’re increasing the amount of Hero hits required. We are also are seeing a higher win rate for his Ruinous Affliction talent compared to others on his Level 16 tier. Rather than nerf this talent, we decided to buff the other options to make the tier more competitive and to make his late- game power spike more powerful.


2016-08-09 Patch Notes

Bug Fixes

  • Gul'dan: Bonus Ability Power granted through the Darkness Within Talent will now correctly apply to all ticks of Drain Life Healing.
  • Gul'dan: Heroes affected by Horrify will now properly run directly from the center of the cast into nearby Gates and Towers, rather than attempt to path around them.
  • Gul'dan: Horrify’s Fear effect will now correctly be paused when enemies hit by the Ability enter Zeratul’s Void Prison.
  • Gul'dan: The tooltip for the Consume Soul Activated Talent now properly lists that it stores up to 2 charges.
  • Sylvanas: Mind Control’s visual effects will no longer stretch across the Battleground, and Sylvanas will no longer attempt to chase Gul'dan if he uses Teleport to Demonic Circle during Mind Control’s casting time.

Stats

  • Base Health increased from 1650 to 1700
  • Health Regen increased from 3.44 to 3.54

Abilities

  • Fel Flame (Q)
    • Damage increased from 181 to 200

      • Cooldown reduction increased from 6 to 7 seconds
  • Level 13
    • Healthstone (Active)
      • Heal amount reduced from 30 to 25% of maximum Health

Developer Comments: Gul'dan’s performance ended up being a bit lower than we expected, so we’re giving him some buffs to compete with other Heroes. His Fel Flame should be a little more threatening, which we’re also hoping will greater incentivize players to take talents related to the ability. As a side-effect of his Health buff, we’re slightly nerfing his Healthstone talent to keep it consistently powerful with its current version. We are also making some small tweaks to other talents help their pick and win rates.
