Attack Opening (Japanese: 攻撃の開放 Attack Opening) is a three-tiered passive type C skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Atk Opening 1, Atk Opening 2, and Atk Opening 3 in order from lowest to highest. Units with an Atk Opening skill takes the strongest unit on the field other than the user and further boosts their Attack for the turn at the start of the user's phase; the size of the Attack boost presumably increases with the skill's tier.
