Warriors: Three Hopes

Duality (Japanese: 陰陽の法則 Law of yin and yang) is an ability in Fire Emblem Warriors: Three Hopes. It is the Unique Action Ability of Arval, and allows them to imbue their attacks with either the light or the dark element. Players can switch between the two by pressing the ZR button. When switching, an additional attack is triggered, with its power increasing with the ability's level.

In Fire Emblem Heroes, it is a passive type A skill. Duality comes in only one tier. Duality boosts its user's attack and resistance, grants weapon triangle advantage against all three colors and neutralizes effects that alter weapon triangle advantage or disadvantage, and allows its user to make a guaranteed follow-up strike should their HP is not low at the start of combat.
