Firefly Premium Team

For this team, Firefly, Lingsha, and Fugue will work together in dealing Super Break DMG to enemies. The Dahlia provides more Break Effect and allows the team to deal Super Break DMG even if the enemy isn't Weakness Broken. She also increases the team's Break Efficiency. For healing, Lingsha is the best choice since she can do AoE healing and increase Break DMG received by enemies.
