Useful when…

Boosting allies’ Break Effect with the Ultimate and Technique.
Adding Super Break DMG to attacks against Weakness Broken enemies.
Building Energy when enemies’ Weaknesses are broken.

What does Backup Dancer do?

The Ultimate grants all allies Backup Dancer for three turns, with duration decreasing at the start of the Trailblazer’s turns. It increases their Break Effect by 15%. When an ally with the effect attacks an enemy in the Weakness Broken state, the attack’s Toughness Reduction is converted into one instance of Super Break DMG. The condition matters: the enemy must already be Weakness Broken, and the ally must still have Backup Dancer.

How do the other abilities support this role?

The Talent restores five Energy immediately whenever an enemy Weakness is broken, helping the Trailblazer use the Ultimate that grants Backup Dancer. The Technique increases all allies’ Break Effect by 30% for two turns at the next battle’s start. The Skill is a five-hit bounce attack, while the Basic ATK is single-target; these attacks can reduce Toughness of the corresponding Imaginary Type, but their listed effects do not themselves grant the team’s Super Break effect.

Where should investment go?

The Ultimate is the defining team effect: its level increases the ability that grants Backup Dancer and Super Break conversion. The Talent is useful for its Energy trigger on Weakness Breaks. Break Boost traces fit the Break-oriented role; ATK and Imaginary DMG boosts support the listed personal attack scaling but do not replace the broken-enemy condition. Promotion and trace unlocks are separate investments.

What limitations matter?

Super Break conversion applies to attacks against enemies already in the Weakness Broken state; it is not a general bonus to every hit. Backup Dancer’s duration ticks down at the start of the Trailblazer’s turns, so frequent Trailblazer turns shorten its remaining duration. The Technique’s Break Effect bonus is a separate two-turn battle-start effect and should not be confused with the Ultimate’s three-turn Backup Dancer.

Limitations and tradeoffs

The main Super Break effect requires both Backup Dancer and an enemy in the Weakness Broken state.
Backup Dancer duration decreases on the Trailblazer’s turns.

Common mistakes to avoid

Expecting Super Break DMG against enemies that are not Weakness Broken.
Forgetting that Backup Dancer duration falls at the start of the Trailblazer’s turns.
Treating the Technique’s Break Effect bonus as the Ultimate’s Super Break conversion.
