Robin Complete Harmony Guide
Version: 2.7+ | Last Updated: 2026-02-10 | Sources: Game8, ldshop.gg, PC Gamer, Gamerant
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 SS Tier Support
- 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
