- Opposing Lineup
| Enemy | Descriptions |
|---|---|
 Lv. 40 Frostnight Herra: Normal |
 High-frequency Elemental DMG | Multi Elemental DMG | Lunar Reaction DMG
Will enter a Gloomveiled state while in combat: All RES is greatly increased. After taking a certain number of DMG instances, it will exit the Gloomveiled state and change its Elemental Type to the element whose DMG it received the most during the time it was Gloomveiled, thereby gaining the corresponding Elemental DMG Immunity and Elemental Effects.
Lunar Reaction DMG is more effective when breaking the Gloomveiled state. If it has taken more Lunar Reaction DMG when it exits the Gloomveiled state, its Elemental Type will change to Elementless, and it will not gain any Elemental DMG Immunity or Elemental Effects. |
Moonsign: Ascendant Gleam
Begins the battle in the "Roaming" state. When its HP is completely depleted, it will enter the "Wild Hunt" state.
When in the Wild Hunt state, even if its HP is reduced to zero, it will regain its HP up to its maximum after a period of time. It can only be defeated when its Max HP is reduced to zero. Drain its HP completely or use Skills enhanced by Moonsign: Ascendant Gleam to send it into a brief Grief-Stricken state. A certain ratio of the DMG dealt to it while in this state will be converted to reduce its Max HP. If you have Moonsign: Ascendant Gleam, this ratio will be increased.
When in the Wild Hunt state, Wilderness Exiles will appear periodically. If you fail to defeat all of these exiles within a certain period of time, your foe will perform a harvest, dealing massive AoE DMG and slaughtering the Wilderness Exiles, restoring its own Max HP based on the remaining Max HP of the exiles. | |
Healing Characters
Consumes a certain percentage of HP in combat to use Hunt Down: When this hits a character, it restores a certain percentage of the foe's HP and attaches a Bond of Life to the character hit.

Descriptions[]
Even when engulfed by the chaos of the Ley Lines and stripped of her original intent, her fighting instincts remain undiminished, capable of driving her to unleash flurry after flurry of lethal attacks.
However, she was unable to shrug off the hardships that she faced after joining the Fatui, choosing instead to bury them deep within her memories. And now, driven by the turbulent Ley Lines, those memories have resurfaced and multiplied as burning resentment in the heat of battle...
Regrettably, in the perilous chaos of the Ley Lines, her sense of reason has long since been swallowed by a lust for battle — one that leads her to mercilessly hunt down intruders and subject them to an onslaught of pure rage...
