Passive (Type A)



Attack/Speed Unity (abbreviated as Atk/Spd Unity; Japanese: 攻撃速さの連帯 Attack/Speed Solidarity) is a passive type A skill which debuted in Fire Emblem Heroes. Atk/Spd Unity is what appears to be a greatly-enhanced fourth-tier equivalent of Atk/Spd Bond, in that users with it receive large boosts to their Attack and Speed during combat while within two spaces of an ally, with a further boost that basically reverses any penalties in those stats on its user.
