An Ad-lib Performance is a type of special attack in Tokyo Mirage Sessions ♯FE.
An Ad-lib Performance is a type of Extra Skill that party members can learn as progress is made in the game. It is triggered at random when using a standard command skill that it aligns with. For example, Kiria's Ad-lib Performance "The Labyrinth," a powerful ice attack that hits all enemies, may trigger when the player selects to cast a spell in the Bufu-line of ice spells. Ad-lib performances are inspired by the characters' side stories and the productions they take part in.
Ad-lib Performances always succeed at damaging enemies, even if the enemy is normally immune to the attack's element.
