Duo Heroes (introduced in Ver. 3.10.0) are Heroes who are accompanied by a related Hero (or Heroes) from the same title. Duo Heroes come with exclusive Duo Skills that can generally only be used once per map. Except for Ephraim Dynastic Duo Face FC.png Ephraim: Dynastic Duo, all Duo Heroes appear in Special Heroes summoning events.

Duo Heroes are not to be confused with Heroes with the  Pair Up ability. Duo Skills cannot be used by units deployed using Pair Up. Harmonized Heroes are Duo Heroes where each Hero comes from a different title.

Features[]

  • Exclusive Duo Skills that provide unique effects.
    • Duo Skills cannot be used by units deployed using Pair Up.
    • Unless specified otherwise, Duo Skills can only be used once per map.
    • Duo Skills cannot be used when under the effect of an opposing team's  Duo's Hindrance in Aether Raids.
    • Duo Skills may be refreshed using the effect of  Duo's Indulgence, unless Duo's Hindrance is still active.
  • Standard Effect: Duel. Duo Heroes are treated as if they have stats equal to their listed Duel effect.
  • Duo Heroes have a special voiced conversation available from their unit screen.
