Attack Smoke (Japanese: 攻撃の紫煙???) is a three-tiered passive type C skill which debuted in Fire Emblem Heroes; the individual tiers of the skill are known as Atk Smoke 1, Atk Smoke 2, and Atk Smoke 3 in order from lowest to highest. Units with an Attack Smoke skill drop the Attack of all foes within two spaces of the user after the user's combat until the end of the target's respective actions; the size of the Attack drop increases with the skill's tier.
