Trailblazer (Harmony · Stelle)

Imaginary Harmony Break support

Released May 8, 2024

Trailblazer (Harmony · Stelle) provides the same listed Harmony kit as the Caelus form: team Break Effect, Super Break conversion against Weakness Broken enemies, and Energy from Weakness Breaks. Consider this form when the party can attack broken enemies during the Ultimate’s support window.

Understand Trailblazer (Harmony · Stelle)

Useful when…

Granting the party Break Effect through the Ultimate.
Converting Toughness Reduction into Super Break DMG during the broken state.
Starting battles with a temporary Break Effect increase.

How does the Ultimate help allies?

All allies gain Backup Dancer for three turns, decreasing by one at the start of each Trailblazer turn. While it is active, allies gain 15% Break Effect. When they attack an enemy whose Weakness is Broken, the attack’s Toughness Reduction converts into one instance of Super Break DMG. Both conditions are important: Backup Dancer must remain active, and the target must be Weakness Broken.

What supports uptime and combat entry?

The Talent restores five Energy immediately when an enemy Weakness is broken. The Technique grants all allies 30% Break Effect for two turns at the start of the next battle. The Skill bounces five times among enemies, whereas the Basic ATK hits one target. These attack patterns are distinct from the Ultimate’s party support effect.

What is worth improving?

The Ultimate directly supports the team’s Break Effect and Super Break conversion, while the Talent contributes Energy after Weakness Breaks. Break Boost traces are aligned with that role. Personal ATK or Imaginary DMG boosts apply to the listed attacks but are a separate benefit. Prioritize the support mechanics if that is why you are using this form; promotion and trace unlocking remain separate progression tracks.

What should you not assume?

The Ultimate does not make every attack Super Break: it converts Toughness Reduction only when the target is already Weakness Broken and the ally has Backup Dancer. Its duration falls at the start of the Trailblazer’s turns. The pre-battle Technique bonus lasts two turns and does not itself apply Backup Dancer.

Limitations and tradeoffs

The central damage support requires a broken target and active Backup Dancer.
The Ultimate’s duration is tied to the Trailblazer’s turns.

Common mistakes to avoid

Using Super Break as if it applied to unbroken enemies.
Letting Backup Dancer expire through the Trailblazer’s turns without accounting for its timing.
Confusing the Technique’s two-turn bonus with the Ultimate’s Backup Dancer effect.
