Description Grants Spd+3. Unit can counterattack regardless of foe's range. If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats × 4 (max 40%).

At start of turn, if unit is adjacent to only beast or dragon allies or if unit is not adjacent to any ally, unit transforms (otherwise, unit reverts). If unit transforms, grants Atk+2, and if unit initiates combat, inflicts Atk/Def-4 on foe during combat and foe cannot make a follow-up attack.

Notes[ | ]

  • The damage-reduction is calculated after offensive Specials and damage boosting effects such as Icon Class Blue Lance Arcane Lúin and Status Effect Dominance Dominance.
    • If a skill such as Skilliconspecial Miracle or Everliving Domain Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
    • Percentage-based damage-reduction effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Status Effect Triangle Adept Triangle Adept and the weapon-triangle advantage boost.
      • For example, if both Buffer 4 Buffer 4 and Skilliconspecial Godlike Reflexes activate, the maximum total damage-reduction is 70% instead of 90%, since the two skills reduce the damage to (1 − 50%) × (1 − 40%) = 30% of the original damage.
    • For more information, see Damage calculation.
  • Sources of effects that reduce damage-reduction:
  • Sources of damage-reduction neutralization:
  • When equipped with skills such as Beast Sense 4 Beast Sense 4 and Beast N Trace 3 Beast N Trace 3, a Icon Type Beast Beast unit will transform out of combat on turn 1 regardless of whether the transformation conditions of the user's weapon are met.
  • The Atk+2 granted by Nightmare Horn when the user transforms is a stat boost, not a Status Effect Bonus bonus.
  • "If unit initiates combat" means if the user starts combat during the player phase. The unit does not need to deal damage, nor be the first to attack.
    • However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
  • The stat decrease that can be applied by Nightmare Horn is considered a temporary debuff.
  • Nightmare Horn can prevent the foe from making a standard follow-up attack.
  • "If unit transforms" refers to out of combat transformations of Icon Type Beast Beast units. Transformations during combat will not trigger the stat boost, temporary debuffs, and follow-up preventing effects.
    • However, if the effect(s) apply after combat, the unit must also survive combat to fulfill this condition.

Cost
Nightmare Horn W +3 HP Grants Spd+3. Unit can counterattack regardless of foe's range. At start of combat, if foe's HP ≥ 50%, grants Atk/Spd/Def/Res+4 to unit during combat. If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats × 4 (max 40%). At start of turn, if unit is adjacent to only beast or dragon allies or is not adjacent to any ally, unit transforms (otherwise, unit reverts). If unit transforms, grants Atk+2 to unit, inflicts Atk/Def-X on foe during combat (X = number of spaces from start position to end position of whoever initiated combat + 3; max 6), and also, if X ≥ 5, reduces damage from foe's first attack by 30% during combat.
Enables【Canto (Rem. +1)】.

Accelerates Special trigger (cooldown count-1). At start of combat, if unit's HP ≥ 25%, grants Atk/Spd/Def/Res+4 to unit and neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat.
Grants Spd+3. Unit can counterattack regardless of foe's range. At start of combat, if foe's HP ≥ 50%, grants Atk/Spd/Def/Res+4 to unit during combat. If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats × 4 (max 40%).

Enables【Canto (Rem. +1)】.

Accelerates Special trigger (cooldown count-1). At start of combat, if unit's HP ≥ 25%, grants Atk/Spd/Def/Res+4 to unit and neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat.

【Canto (Rem. +1)】
After an attack, Assist skill, or structure destruction, unit can move spaces = any movement not already used that turn +1. (If unit used a movement skill that warped them, its remaining movement is 0.)

(Unit moves according to movement type. Once per turn. Cannot attack or assist. Only highest value applied. Does not stack. After moving, if a skill that grants another action would be triggered (like with Galeforce), Canto will trigger after the granted action. Unit's base movement has no effect on movement granted. Cannot warp (using skills like Wings of Mercy) a distance greater than unit's remaining movement +1.)

Notes[ | ]

  • The stat increase that can be applied by refined Nightmare Horn is considered a temporary buff.
  • The calculation of "spaces from start position to end position" counts the total number of spaces from the initiator's starting position to the end position before combat.
  • The damage-reduction is calculated after offensive Specials and damage boosting effects such as Icon Class Blue Lance Arcane Lúin and Status Effect Dominance Dominance.
    • If a skill such as Skilliconspecial Miracle or Everliving Domain Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
    • Percentage-based damage-reduction effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Status Effect Triangle Adept Triangle Adept and the weapon-triangle advantage boost.
      • For example, if both Buffer 4 Buffer 4 and Skilliconspecial Godlike Reflexes activate, the maximum total damage-reduction is 70% instead of 90%, since the two skills reduce the damage to (1 − 50%) × (1 − 40%) = 30% of the original damage.
    • For more information, see Damage calculation.
  • Sources of effects that reduce damage-reduction:
  • Sources of damage-reduction neutralization:
  • "If unit transforms" refers to out of combat transformations of Icon Type Beast Beast units. Transformations during combat will not trigger the temporary debuffs and damage-reduction effects.
    • However, if the effect(s) apply after combat, the unit must also survive combat to fulfill this condition.
