Seiðr Shell (Japanese: 魔弾 Magic Bullet) is a special skill which debuted in Fire Emblem Heroes. Seiðr Shell is a skill that, on its user's first turn, accelerates its cooldown by three points (enough to arm it provided it's not slowed by another effect), and whenever it is actually triggered, boosts its user's damage output by 15 points and calculates the total damage using the lower value of the target's Defense and Resistance. Seiðr Shell is considered to be a part of the Glowing Ember special skill family.
