Aurora
Aurora hero Revamped

All Documented Modifications (5)
Designer Note
"Before you stands Aurora, the legend of the Northern Vale, sovereign of snow's frigid reign, goddess of Queen's Peak, and immortal Maiden of the Glacier!" Unlike previous updates, we've completely reworked Aurora's skills, modeling, and special effects. We believe she will once again shine on the battlefield!
Upon taking fatal damage, Aurora freezes, becoming invincible and gradually recovering HP. This skill will only take effect once in a period of time. Aurora's freeze effects can affect Turrets.
Aurora summons an icy meteorite to strike at the target location, dealing damage and slowing targets hit. Afterward, hailstones fall, dealing multiple instances of damage.
Aurora blows Frosty Breeze in the target direction, dealing damage to enemies hit, freezing them, and creating a frozen area at the far-end of the attack that deals extra damage to enemies in the area.
Aurora creates a frost path in the target direction, dealing damage and slowing targets hit. The frost path gradually becomes glaciers that spread until reaching their maximum size and shatter, dealing damage to all enemies in the area and freezing targets. Every Magic Power that Aurora has will increase the freeze duration.

By changing the width of Paquito's Skill 2 and Ultimate to be identical to his Skill 1, we hope that players will now land his skills more consistently with a better hit rate.

Lunox

Wanwan
Wanwan hero Adjusted

Adjustments applied to Tiger Pace.

All Documented Modifications (2)
Designer Note
Wanwan still has incredible agility. We tried to reduce her jump speed to balance it out, but it really affected her control experience. This time we will reduce her jump distance to weaken her ability to chase and kite with minimal impact on her control experience.
Slightly reduced jump distance. Basic Attack Damage and Attack Effect Ratio: 110% → 100%

Tier: D

Karrie
Karrie hero Nerf

Adjustments applied to Lightwheel Mark.

All Documented Modifications (2)
Designer Note
We noticed that Karrie was dealing a lot of damage even in a defensive build. A tanky, high-damage Marksman limits the opponent's ability to counter. So we lowered the base damage on her passive, so she now has to have a more offensive build to get the same damage output.
6%-8% of the target's Max HP → 5% (+1% of Extra Physical Attack) of the target's Max HP
Role: Marksman
Tier: C
