Dahlia at a Glance
Who Is Dahlia?
Brain Jar Games describes Dahlia as “the child of two legendary musicians” who “should have had it all. Instead, she became the poster child for grief and loss.” A pianist and dancer, “she blooms, she blazes, and she leaves only ghosts behind.”
- • She fights with twin piano fans named Sugar and Spice
- • She “dances circles around you with her phantom dance partners”
- • Her stage pulls Charlie through nightclubs, jungles, and the aftermath of a volcano
- • Her music is described as Latin beats meeting Spanish piano
- • The Encore “was her home long before Charlie Disco” — beat her to unlock her quests there
Dahlia’s Combat Style & Known Attacks
Brain Jar Games has not published a full move-by-move breakdown, so we stick to what the official patch notes state and mark the rest as not stated.
- Long, flowing combos — Dahlia “prefers longer attack combos as she will jump in and out of Charlie’s range.”
- Phantom dance partners — after her combos she “dances circles around you with her phantom dance partners.”
- Panther Eyes — one of Dahlia’s named attacks, referenced in the October 7, 2026 hotfix (a bug where KOing her with Burn during Panther Eyes could softlock the level).
- A tornado — the October 1, 2026 hotfix fixed an issue where players could “ride” the tornado during the Dahlia boss fight.
- Burn — her fights introduce the new Burn status effect, which deals damage per beat.
Exact phase count, parry windows and per-attack timings are not stated in the official patch notes, so we do not invent them here. For the newest details, check the game’s Steam news feed.
