Kachina's burst provides off-field Geo damage and interruption resistance, fitting well into Geo teams alongside main carries like Alhaitham or Hu Tao. Pair her with other Geo characters to leverage resonance benefits and maximize her contribution without field time. Building ATK and Crit on a 4-star polearm like The Catch (when freed from Hydro supports) or Favonius Lance for energy sustainability will support consistent burst uptime.
