Fires a Cryo Round at enemies in front to deal damage and inflict Cryo. Targets with Cryo stacks receive additional damage and lose 1 stack when hit by Hailey's firearm attack.

Unleashes a Chill Vortex around her, knocking back hit targets and firing a massive Freezing Beam in the direction of the crosshairs. Inflicts Cryo on targets hit based on Enemy AoE.

Grants Hailey Cold Fury every second. The Cold Fury effect gradually decreases her Movement Speed, but greatly increases her Firearm and Skill Critical Hit Rates and Firearm Penetration. When Cold Fury reaches maximum stacks, Hailey becomes immune to Knockdown and gains an increase to her Firearm and Skill Critical Hit Damage. However, when using Roll or Grappling Hook, the stacks decrease.

Equips her Unique Weapon . When hitting an enemy with the Unique Weapon, greatly increases Penetration and Firearm ATK and deals additional Chill skill damage. Recovers a portion of MP upon successfully attacking Weak Points. Partially decreases the Cooldown of the Unique Weapon skill when the skill ends depending on the number of fired bullets.

Proportional to the distance between the target and Hailey, the Weak Point Damage decreases the closer it is to the target and increases the further it is.
