characters
Affected by the Ley Line disturbance, after the battle begins, the foe will sequentially deploy Electro, Pyro, and Hydro Wards to protect itself, while adjusting its attacks to match the corresponding element.

Affected by the Ley Line disturbance, the foe gains increased All RES. During battle, it leaps into the air more frequently, temporarily hovering in place and continuously unleashing powerful sonic shockwaves while airborne.
During battle, the foe will deploy a Cryo Ward for protection and leap into the air to charge up Frosthail Execution. After a period of time, it will unleash Frosthail Execution and instantly defeat your active character. Break the Ward with Elemental Reactions to knock the foe to the ground, interrupt its attack preparation, and deal a single instance of massive DMG based on the amount of DMG the Ward absorbed. While the foe is preparing its attack, all characters in your party will regain Elemental Energy, Fighting Spirit, or Serpent's Subtlety. If, after a period of time, the Ward has not been broken, Frosthail Zones will appear on the ground: Triggering Elemental Reactions to destroy each Frosthail Zone can also weaken and eventually break the Cryo Ward.
Affected by the Ley Line disturbance, when the foe begins charging up Frosthail Execution, a Disruption Vortex will appear on the field, dealing AoE Cryo DMG to both allies and enemies. If the vortex hits the foe, the foe's Anemo RES will be reduced and its Ward will be depleted. | |

Descriptions[]
In the Ley Line memories, they send unending shivers of pain through the bones of the world, like thorns that pierce too deeply to extract.
In the war against the Abyss, it was once as sharp and incisive as a blade of frost. Yet, under the tumultuous influence of the Ley Lines, it has turned its cutting edge towards an entirely undeserving foe...
Under the corrupting influence of the Ley Lines, this device that once defied the norms of physics has degenerated into a cold and emotionless tool of destruction.
The special station it holds in the menagerie of abyssal monsters lends it an extraordinary sense of menace. Those unfortunate enough to die by its hands merge with the Ley Line memories, distorting their piteous whispers into curses that cut like knives...
However, great powers of perception are not always a blessing, and swept up in the turbulence of the Ley Lines' undercurrents, its wings have lost their customary warmth, as unending suffering and limitless anger slowly congeal into ice...
Though its metal shell may still shine with the luster of old, in the Ley Lines' twisted memories, this gigantic device has turned away from the object of its design, retaining only its capacity for destruction...
In the twisted recollections of the Ley Lines, they surface as frenzied destroyers, raising wave after wave of calamity with their blasphemous powers...
Observing the totality of suffering and sorrow, it has been consumed by the twisted memories of the Ley Lines, transforming into a blizzard of near-absolute cold that rages with the winds of unfathomable chaos...
Transformed by the chaotic Ley Lines, its core has grown violently unstable, and the gravitational fields it unleashes now surge with the force of tsunamis, ready to engulf the land...
