The Nightmare Horn is a Strike that debuts in Fire Emblem Heroes as the exclusive weapon of Freyja.


Nightmare Horn innately grants Freyja +3 Spd and can counterattack any foe regardless of range. If her Speed stat is higher than her foes, she reduces damage from their attacks during combat as well as damage from area of effect special skills. This reduction is based on the difference in Spd x4, maximizing at 40% reduced damage.

If she is either adjacent only to Beast/Dragon units or is not adjacent to any ally unit, she transforms. In her transformed state, Freyja gains an innate +2 Atk and if she initiates combat, she inflicts Atk/Def -4 on her foe and they cannot perform a follow-up attack.

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.
