Rotation Tips

2. Swap to sub-DPS: Apply elemental reactions and generate Concerto.
3. Swap to Lumi (Intro): Apply Glacio Frazzle and gain initial buffs.
4. Build resources: Use Normal Attacks and Skills to build energy/buffs.
5. Cast Liberation: Unleash burst damage at optimal timing.
6. Maintain DPS: Continue attacking during buff windows.
7. Swap out: Trigger Outro skill, switch to support to restart cycle.

Tip: Always time your Liberation with full buffs for maximum damage output. Maintain Glacio Frazzle on enemies for consistent damage.
