Windsong — Review & Analysis
- Self-fuels her own crit: [Scale] (up to 15 stacks) plus Insight III's +10% Crit Rate & Crit DMG on entry mean she barely needs an external crit buffer.
- Incantation I converts overflow Crit Rate into Crit DMG — no wasted stats, rewarding heavy crit stacking.
- The Ultimate enters [Surveying] with no Moxie loss and re-casts Incantation I, creating a huge single-target burst window; [Obscurity] also shreds enemy Crit Resistance for the whole team.
- Star afflatus is countered by Plant (takes +30% DMG / weaker against Plant), so watch out for Plant-heavy lineups.
- She needs time to stack [Scale] and Moxie before erupting, so short fights or the opening rounds see modest output.
Level the Ultimate first to maximize the chained burst window, then Incantation I as the main single-target crit hit. Since she generates plenty of Crit Rate herself, pick Psychubes leaning toward Crit DMG / single-target damage amplification to cash in on the overflow-Crit-Rate-to-Crit-DMG conversion; pair her with crit-happy allies to feed extra [Scale] stacks.

Where to Get
Teams with Windsong
Windsong, Blonney and Kanjira all carry the Confusion tag — stacking Confusion on the same enemy makes it more likely to attack its own side, effectively removing it from the fight without needing to burst it down. La Source keeps everyone alive with Moxie + Heal while the debuff resolves. None of the four needs a Euphoria.
Teams →Tooth Fairy, Matilda and Voyager all tap into Confusion together with Crit — combining it across three kits at once outperforms any single carry doing it alone. Name Day keeps the line-up alive with Heal so that payoff has time to land.
