Robin

Physical Harmony support who advances the team and adds damage during Concerto

Released May 8, 2024

Robin boosts all allies’ damage with her Skill, then uses her Ultimate to make teammates act immediately and enter Concerto. While Concerto lasts, she raises allied ATK and adds a fixed-crit Physical hit after each ally attack, but Robin herself cannot take turns or act until the state ends. Consider her when the team can make use of the coordinated action window and frequent allied attacks.

Understand Robin

Useful when…

  • Amplifying party damage before a short sequence of actions
  • Giving teammates an immediate action through her Ultimate
  • Adding Physical additional damage after allied attacks during Concerto

What happens during Concerto?

Vox Harmonique, Opus Cosmique makes every teammate except Robin immediately take action. During Concerto, all allies gain ATK based on Robin’s ATK plus a flat amount. Each ally attack triggers one instance of Robin’s Physical Additional DMG, with the listed CRIT Rate and CRIT DMG fixed for that damage. Robin is immune to Crowd Control debuffs during the state, but she cannot take turns or actions until the countdown ends; then she immediately acts. Pinion’s Aria increases all allies’ damage for three turns at the listed level, with its duration decreasing at the start of each Robin turn. Her Talent grants a small partywide CRIT DMG increase and gives Robin Energy after allied attacks.

When does she help most?

Her Ultimate’s immediate actions are especially relevant when several teammates have actions worth taking during the same window. Repeated ally attacks during Concerto also trigger Robin’s additional damage each time, while the ATK boost applies across the party. Her Technique creates a dimension that prevents enemies from attacking Robin and restores Energy at the start of each wave if combat begins while it is active. The Technique dimension lasts 15 seconds, and only one ally-created Dimension Effect can exist at a time.

What investments are useful?

Raise the Ultimate when you want to improve its party ATK boost and triggered additional damage. The Skill supports the party’s damage during its duration, while the Talent’s CRIT DMG and Energy return support the whole kit. Her listed bonus traces include ATK and SPD. The Basic Attack is a single-target hit and is less central to her support function. Promotion and high trace ranks require increasing materials, so prioritize the abilities used to create the team’s main damage window before spending on less-used basic attacks.

What limits the window?

Robin cannot act during Concerto, so her Skill and other actions are unavailable until the countdown ends. Her additional damage triggers after allied attacks, not simply at the start of the state. The Skill’s buff duration decreases on Robin’s turns, while Concerto itself uses its own countdown in the Action Order. Her Technique’s damage prevention is specifically described as enemies not attacking Robin; it is not a partywide defensive effect.

Limitations and tradeoffs

  • Robin is unable to act for the duration of Concerto.
  • Her additional damage requires ally attacks during that state.
  • The Technique protects Robin from enemy attacks in its dimension; no equivalent protection for allies is specified.

Common mistakes to avoid

  • Expecting Robin to take actions while Concerto is active.
  • Treating the Ultimate’s additional damage as automatic each turn rather than triggered after allied attacks.
  • Assuming the Technique’s enemy avoidance applies to the whole party.
