Dual Arts are a type of special attack in Tokyo Mirage Sessions ♯FE.
Dual Arts are powerful special attacks that can be performed by specific pairs of party members. When the proper criteria are met, the player can select to perform an available Dual Art, and the party members involved will attack the enemy in tandem. It is not required that both party members involved in a Dual Art be in the active three-person party in order to use it. The Dual Arts take the form of short skits, such as Tsubasa and Eleonora performing an idol duet while shooting magic hearts at the enemy, or Eleonora and Toma demonstrating a rivalry as they team up to attack, with Eleonora leaping off of Toma's head.
The player gains access to more Dual Arts as side-missions are completed.
