Lv. 1: Whenever an enemy unit is inflicted with Cold, gains 1 stack of Ice Soul Sigil, stacking up to 7 times. When there is no Frost Vortex present on the field and Ice Soul Sigil reaches 7 stacks, Yekaterina will generate a Frost Vortex at the center of the enemy team. During the duration of Frost Vortex, it deals magic damage equal to 150-210% of Attack per second to enemy units within the area (the longer the Frost Vortex lasts, the higher the damage, reaching maximum after 10 seconds, at which point this damage is doubled), and reduces the movement speed of enemy units within the area by 90% and Attack Speed by 45%. Lv. 2: Whenever an enemy Luminary or Wyrm within the Frost Vortex enters the Evaporation or Flash Freeze status, immediately release Frozen Armor (can trigger at most once every 3 seconds). Lv. 3: Increases Attack by 10% and Shield Efficiency by 4%. Lv. 4: Ice Blast After dealing damage to enemies within the Frost Vortex, additionally applies Freeze for 4 seconds.

During the Shield's duration, increases the target's Damage Amplification by 10%. When the holder of Frozen Armor deals damage to enemy units under Cold status, it deals additional damage equal to 150-210% of the caster's Attack. Each time an ally uses an Overdrive, gains 1 stack of Awakening. When casting this skill, consuming 3 stacks of Awakening enhances the skill, allowing an additional target to be selected.
