Skirk’s Elemental Burst does not consume Elemental Energy but instead uses Serpent’s Subtlety. The Elemental Burst’s damage is increased when Serpent’s Subtlety exceeds 50. Serpent’s Subtlety can be obtained through her Elemental Skill or by absorbing Void Rifts, which are generated when allies trigger Cryo-related reactions.
Skirk can use her skill to switch to Seven-Phase Flash mode. During this mode, her Normal Attacks are infused with the Cryo element and deal increased damage. Her Elemental Burst is also enhanced. When Skirk uses the enhanced Elemental Burst, her Normal Attack damage is further increased, and she absorbs nearby Void Rifts.
