Weapon (beast)

First game


Brightmare Horn (Japanese: 夏夜の悪夢の角 Summer Night's Nightmare Horn) is a weapon skill in the beast category which debuted in Fire Emblem Heroes; it is a personal weapon of the summer variation of Freyja. Brightmare Horn is a skill that boosts its user's Speed at all times, further boosts its user's stats during combat if their HP is sufficiently high, and also reduces the target's damage output based on how much faster the user is than the target. Additionally, if the target's HP is sufficiently high and is transformed, any effects that would prevent the user from making a follow-up strike are neutralized.
