Developer comments: Based on player feedback, we wanted to reward precision with Slowball. Landing crits now gives a stronger slow, letting Mei players who hit their mark feel extra frosty while making it clearer when enemies are in real trouble.
Slowball - Power
- Added: Critical hit applies 30% instead.
8/26/2025
Developer Comments: Based on our testing data, Mei was having a hard time dealing with fliers. This update gives her a new counter item to help level the playing field and give her a bit more edge against airborne enemies.
Coldspot – Rare Survival Hero Item
- Added: Primary fire applies 35% Slow for 1.5s to an airborne enemy.
7/24/2025
Developer Comments: Slowball has been effective at disrupting enemies, but the slow was a bit too punishing for how easy it was to apply. We’re reducing the slow strength to make it less oppressive while still rewarding accurate shots and smart use of Mei’s secondary fire.
Slowball - Power
- Decreased slow to 15% (Down from 30%).
7/22/2025
Developer Comments: This update improves its consistency so you can land those chilly plays more reliably. Enjoy freezing the competition!
Slowball - Power
- Now normal hit with Secondary Fire will also apply slow to the hit enemy.
7/3/2025
Developer Comments: Snowball Flight now synergizes with Twice as Ice, expanding Mei’s mobility options and enabling more frequent use of Mini-Blizzard. This update gives her more fluid movement and crowd control opportunities, encouraging dynamic play and rewarding smart positioning.
Twice As Nice - Power
- Twice As Ice also resets next Snowball Flight's cooldown.
6/24/2025
Developer Comments: While Avalanche was doing its job, it often created confusion for enemies where many couldn’t clearly understand why they were being slowed or where the effect was coming from. We’re shifting the focus of the power to enhance Mei’s primary fire, giving her more burst potential and rewarding players who can cage the enemy within a mini-blizzard or a blizzard. This should make the power feel more intuitive and impactful for both Mei and her opponents.
Avalanche - Power
- Removed.
Cold Blaster - Power
- New Power added.
- Endothermic Blaster's primary fire does 20% increased damage to enemies within Blizzard.
Permafrost - Power
- Increases Mei's size by 15% when above 30% ability power.
Himalayan Hat - Epic Weapon Hero Item
- Increased attack speed to 15% (up from 10%).
5/29/2025
Developer Comments: We’re looking to enhance Mei’s survivability in moments where Cryo-Freeze isn’t available by improving the synergy with Blizzard effects. This adjustment should give Mei more defensive value during her ultimate or mini-Blizzard, allowing her to better sustain herself in skirmishes and maintain pressure.
Blizznado - Power
- Increased Heal per second to 15% (up from 5%).
5/1/2025
Developer Comments: While rolling around in ice balls has been very fun, we feel that the power currently feels too consistent at disrupting players for a long duration ability. We're hoping with these changes that it will still feel powerful but reduce its ability to carry an enemy around for its entire duration.
Coulder - Power
- Reduced the knockback frequency rate by 60%.
- Increased how far enemies are knocked back.
- Increased the damage dealt per knockback to 20 (up from 10).
4/22/2025
Chilling Reach
- Removed.
Biting Cold
- Moved to Minor perk.
- Secondary fire hits slow enemies by 20% for 1.5 seconds.
Deep Freeze
- New Major Perk.
- Continuously hitting enemies with primary fire freezes them for a short time.
4/1/2025
Developer Comments: The cold doesn't bother Mei anymore, but it may bother Mei's enemies.
Cyro-Freeze
- Now creates a miniature Blizzard.
- Mei can now move during Cryo-Freeze.
3/18/2025
Developer Comments: The cooldown increase for Permafrost has been removed to ensure it does not create negative impact for Ice Wall.
Permafrost
- No longer increases cooldown of Ice Wall.
2/18/2025
Chilling Reach
- Primary Fire's range is increased by 30%.
Permafrost
- Ice Wall's duration and cooldown are increased by 2 seconds.
Biting Cold
Secondary fire hits slow enemies by 15% for 1.5 seconds, stacking up to 30%.
Cryo-Storm
- Cryo-Freeze slows and deals 70 damage per second to nearby enemies.
12/17/2024
Ice Wall
- Wall Health increased from 250 to 300.
6/20/2024
Developer Comments: Mei's damage output over time is intended to be on the low end for a Damage hero, as she offers strong utility and survivability through her ability kit, but we would like to make the secondary fire icicle more rewarding by increasing the damage and slightly more difficult to land consistently.
Endothermic Blaster
- Secondary fire base projectile size reduced from 0.15 to 0.12 meters.
- Secondary fire damage increased from 75 to 85.
4/1/2024
Developer Request: Definitely do not use this to get to spots on the map you’re not supposed to get to, thanks.
Avalanche Launch
- New Ability.
- Press Jump in the Air to activate.
- Creates a large Ice Pillar under Mei.
- Can be canceled with Interact.
3/8/2024
Endothermic Blaster
- Ammo increased from 120 to 140.
Cryofreeze
- Heal per second increased from 50 to 62.5.
2/13/2024
- Health increased from 250 to 300.
12/5/2023
Developer Comments: We're reducing the maximum ammo to limit how long Mei is able to continuously slow an enemy target now that the primary fire deals more damage.
Endothermic Blaster
- Maximum ammo reduced from 150 to 120.
10/31/2023
Developer comments: With some of the recent changes, Mei is now slightly overperforming. Her improved primary fire damage output is good for her role, so rather than adjust that further, we're instead targeting the more commonly frustrating crowd control aspect of its slowing effect.
Endothermic Blaster
- Slow effect decreased from 40 to 30%.
10/10/2023
Added the hero-specific option:
- Cryo-freeze Cancel Input – All by default.
9/1/2023
Developer Comment: Mei is still underperforming after her last set of changes, so we are increasing the effectiveness of primary fire and improving the quality of life to Deep Chill.
Endothermic Blaster
- Damage increased from 65 to 70 per second.
- Duration before slow falls off between primary fire hits increased from 0.5 to 0.6 seconds.
Deep Chill
- Bonus damage can now also be triggered with Mei's quick melee.
8/10/2023
Endothermic Blaster
- Primary fire damage per second increased from 55 to 100.
6/28/2023
Endothermic Blaster
Despite the primary fire gameplay feeling more interesting now, Mei's effectiveness overall was negatively impacted by the trade in damage for more slowing utility. We're shifting some of that power back into her damage.
- Maximum slow applied by primary fire reduced from 50% to 40%.
- Primary fire damage per second increased from 55 to 70.
Deep Chill (Passive)
- Maximum slow applied when this effect activates reduced from 75% to 65%.
6/13/2023
Developer Comment: This set of changes is intended to bring back some of the gameplay and feeling Mei's primary fire used to have previously, though without the hard crowd control of a full freeze stun.
Endothermic Blaster
- Damage per second reduced from 100 to 55.
- Primary fire slow is no longer always 40% and now scales from 30-50%.
- Primary fire impacts now build up to a slowing effect that sticks to the enemy target for 1.5 seconds and slows them for 75%.
- Secondary fire impacts can detonate this new slow effect, dealing an additional 40 damage.
5/9/2023
Cyro-Freeze can now be canceled by pressing the ability’s button again
Added the Hero-Specific Options:
- Hold To Use Cryo-Freeze - Off by default
- Hide Cyro-Freeze Cancel Text - Off by default
- Hide Cryo-Freeze Timer - Off by default
- Default Ice Wall Rotation - Horizontal by default
- Ice Wall Confirmation Input - Primary Fire by default
3/7/2023
Developer Comment: Mei's Blizzard ultimate cast time sometimes led to situations where the animation appeared to have been completed, but there was still additional time that it could get interrupted. This change will help mitigate that feeling without significantly reducing counterplay.
Blizzard
- Blizzard ultimate cast time reduced from 0.5 to 0.4 seconds
2/7/2023
Blizzard
- Ultimate cost reduced 5%
