Developer Comment: Our main goal for Jaina's changes was to spruce up her talent tree while disrupting as few of her existing builds as possible. Her new baseline quest to unlock Improved Ice Block should allow for more play making potential, which we are adding as a response to players who were disappointed when we moved the talent to Level 20. We also heard feedback from many players that the removal of Bolt of the Storm off of heroes like Jaina has hurt their play making ability and overall fun, so we're going back a bit on our decision to take it away on her. While we want to be more careful where we add these Blink-type abilities, we believe there is a place for it on Jaina, and have added an offensive use case which should hopefully allow her to make more aggressive plays in the late game.

    • Snow Crash (W)
      • Removed

Developer Comments: A lot of these changes are designed to further emphasize what we see as Jaina’s unique role: battlefield control. We want to play up her ability to deny areas of the battlefield with Blizzard, and really punish enemies who get stuck inside it. The biggest change in that regard is that she now spawns 3 waves of Blizzard baseline. To go along with these core kit changes, we’ve also changed or moved around a few of her Talents. One of the biggest changes was Snowstorm, which increased the radius of Blizzard, as we found that it lowered the difficulty of landing consecutive Blizzard waves on enemies too much for a Talent in such an early tier.

Bug Fixes

  • Jaina: Casting Blizzard while hidden within a Shrub will no longer prevent players who are outside that shrub from seeing its visual effects.

2016-05-17 Patch Notes

Talents

Conjurer's Pursuit

  • A reward has been added to this Questing Talent.
    • Quest: Gather Regeneration Globes to permanently increase Mana Regeneration by 0.10 per second, up to a maximum of 2.5 per second.
    • Reward: After gathering 25 Regeneration Globes, also increases maximum Mana by 100.

Developer Comments: We’ve added a completion point to this Talent. Upon completing its quest, players will be provided with some additional power. This allows us to offer spikes of power in-between Talent levels, or even for a single player on a team. Now, simply picking the Talent and only partially completing it is worse, but finishing the quest will return a larger reward. Choosing the right Talents on the right Battleground or with the right team composition has always been an important goal for us, and this change pushes this Talent to closer align with that goal.


2016-03-29 Patch Notes

Talents

Arcane Power

  • Duration increased from 5 to 10 seconds

Hero Updates

  • Bolt of the Storm (Talent) removed
  • Improved Ice Block (Talent) moved from Level 13 to Level 20
    • Cooldown reduced from 60 to 20 seconds
    • Duration reduced from 3 to 2.5 seconds
  • Frostbite (Trait)
    • Ice Barrier (Talent) moved from Level 16 to Level 13

Developer Comments: We’ve removed Bolt of the Storm from Jaina because it overcame a core weakness of hers that we think is essential to maintain: her lack of mobility. While there was always the potential for big plays with Bolt, we found that it was more often used as a “get out of jail free card” that helped make up for sloppy positioning after reaching level 20. We’re in the process of evaluating whether or not Bolt should be available to a number of Heroes, which is why it was also removed it from Kael’thas in this patch.

This doesn’t mean that no burst Assassins should have this type of mobility; it’s part of Li-Ming’s core gameplay design, for example. For the types of ranged Heroes for which Bolt is appropriate, we balance around their mobility. For Jaina and Kael’thas, however, we think removing Bolt and compensating them in other ways will result in healthier gameplay and Talent diversity.

Bug Fixes

  • Jaina’s Basic Attacks will now properly refund Mana after learning the Arcane Intellect Talent.

2016-02-10 Balance Update

Hero Updates

  • Basic Attack damage reduced from 89 (+4% per level) to 60 (+4% per level)
  • Frostbolt (Q)
    • Damage increased from 160 (+4% per level) to 190 (+4% per level)
  • Cone of Cold (E)
    • Damage increased from 189 (+4% per level) to 200 (+4% per level)

Developer Comments: We’re starting to pull Basic Attack damage out of characters who don’t rely upon it, namely Jaina and Kael’thas. For Jaina, this will make less of her damage guaranteed and allow for more advanced plays. Jaina’s win rate is also a little on the low end, so we want to offset the Basic Attack nerf and add to her overall power by buffing Frostbolt and Cone of Cold.


2016-02-02 Patch Notes

Hero Updates

  • Ring of Frost (R)
    • Ring of Frost’s inner-area radius now properly matches the Ability’s visual effects

Bug Fixes

  • Jaina’s Ring of Frost now properly affects enemies that overlap the inner-edge of the Ability’s targeting ring.

2015-11-17 Patch Notes

Hero Updates

  • Frostbite (Trait)
    • Deep Chill (Talent)
      • Bonus to the Movement Speed slow applied by Chill decreased from 35% to 30%

Developer Comments: Jaina having a 35% slow available at level 1 is very hard to play against, and resulted in a majority of Jaina players picking Deep Chill. This is a small decrease, but has had a positive impact on our playtesting.


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

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: The Jaina changes are a result of her being too powerful right now, and we have a secondary goal of increasing the play of Ring of Frost. By reducing the impact of summoning a Water Elemental, Jaina loses some of her burst potential unless she chooses Ring of Frost. Water Elemental is now more focused on producing sustained damage.

  • Ring of Frost (R)
    • Cooldown decreased from 100 to 80 seconds
  • Summon Water Elemental (R)
    • No longer deals damage or Chills at the Water Elemental’s spawn location

Bug Fixes

  • After learning the Wintermute Talent, Jaina’s Water Elemental will now properly mirror her Blizzard casts.
