Attack/Defense Push (Japanese: 攻撃守備の渾身Attack/Defense With All One's Might) is a four-tiered passive type A skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Atk/Def Push 1, Atk/Def Push 2, Atk/Def Push 3, and Atk/Def Push 4 in order from lowest to highest. Units with an Atk/Def Push skill boost their Attack and Defense during combat if their HP is full at the start, at the cost of taking recoil damage after combat; the size of the Attack and Defense boosts increase with the skill's tier, with the fourth tier reducing the HP threshold needed for activation but also increasing the recoil.
If user's HP is full at start of combat, boosts user's Attack and Defense by +3 each during combat, but deals 1 damage recoil to user after combat if user attacked during combat.
If user's HP is full at start of combat, boosts user's Attack and Defense by +4 each during combat, but deals 1 damage recoil to user after combat if user attacked during combat.
