Overview
Robin is a 5-star Physical Harmony character who provides exceptional team buffs. Her Ultimate triggers "Concerto" state, granting massive ATK buffs and dealing additional damage when allies attack.
Why Robin is S+ Tier Support (Updated 3.x Meta)
- Party-wide DMG boost and CRIT DMG buff
- ATK buff scales with her own ATK (up to ~1100 ATK to party)
- Concerto state deals additional Physical damage when allies attack
- Ultimate makes all allies immediately take action
- Works universally but excels in Follow-up Attack teams

Key Mechanics
Concerto State (Ultimate)
- All allies immediately advance and attack together
- Grants ATK buff based on Robin's ATK (up to 27.84% at Lv10)
- Fixed CRIT Rate (100%) and CRIT DMG (150%) for Concerto damage
- Robin deals additional Physical damage when allies attack
Why ATK Stacking is Key
- Her ATK buff to party scales directly with her ATK
- Target: 3500-4000 ATK for optimal party buff
- 4000 ATK ≈ 1100+ ATK buff to entire party
