Seal Speed/Resistance (Japanese: 速さ魔防封じSpeed/Resistance Seal) is a two-tiered passive type B skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Seal Spd/Res 1 and Seal Spd/Res 2 in order from lowest to highest. Units with a Seal Def/Res skill will drop its foe's Speed and Resistance at the end of combat through the target's next action; the size of the both stat drops increase with the skill's tier.
