The Speedwing (高速翼 Kōsoku tsubasa) is a Stat booster that recurs across the Fire Emblem Series. Prior to Fire Emblem: The Binding Blade, the Speedwing's original form is the Speed Ring (スピードリング Supīdo ringu). When used, the Speedwing permanently raises its user's Speed by a set number of points that varies from game to game. In TearRing Saga: Utna Heroes Saga, the Speedwing's equivalent is a potion that is simply known as the Agility Plus (AGL プラス AGL Purasu), permanently raising its user's Agility by 2.
