Battle-Hardened Iktomisaurus: Frostbound Resolve

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.
Additionally, the Disruption Vortex can also be affected by pull effects, which may alter its movement path.
