Firefly
Who is Firefly?
Firefly is a 5★ Fire Break/Super Break DPS of the Destruction Path and, as of Patch 4.2, a T0 carry in Memory of Chaos and Apocalyptic Shadow (rising in Pure Fiction) — source: Prydwen. Piloting the SAM mech she enters Complete Combustion via her Ultimate to deal enormous Super Break damage; the release of The Dahlia pushed her back to T0.
Kit Summary
Build toward her Ultimate to enter the Complete Combustion enhanced state, which transforms her Basic and Skill and boosts CRIT.
Enhanced Skill (Fyrefly Type-IV: Deathstar Overload) deals massive Weakness-Break and Super Break damage; her Break applies the Routed debuff (more Break DMG taken, less SPD).
Skill-Point hungry at E0 — needs the Harmony Trailblazer to enable Super Break plus an SP-positive sustain.

The free Harmony Trailblazer is effectively mandatory to enable Super Break.
Gallagher (free) is the best budget sustain because he is Skill-Point positive.
