Passive (Type C)



Defense/Resistance Unity (Japanese: 守備魔防の連帯 Attack/Magic defense solidarity), contracted to Def/Res Unity in-game, is a passive type A skill which debuted in Fire Emblem Heroes; Defense/Resistance Unity comes in only one tier. Def/Res Unity is comparable a fourth-tier equivalent of Def/Res Bond, in that users with it receive large boosts to their Defense and Resistance during combat while within two spaces of an ally, with a further boost that basically reverses any penalties in those stats on its user.
