# Robin (Honkai: Star Rail)
**Robin** is a playable five-star character in the turn-based role-playing game *Honkai: Star Rail*, aligned with the Physical element and the Path of Harmony, a class of characters whose abilities strengthen their teammates rather than dealing primary damage.[1](https://www.prydwen.gg/star-rail/characters/robin) She was introduced in Version 2.2, "Then Wake to Weep", released on May 8, 2024, alongside the character Boothill, as part of the finale of the game's Penacony storyline.[2](https://www.hoyoverse.com/en-us/news/123644) In the game's fiction she is a Halovian singer born in Penacony who rose to cosmic fame, and she uses the power of Harmony to broadcast her music, manifesting "resonance" among her fans and other lifeforms.[1](https://www.prydwen.gg/star-rail/characters/robin)

## Kit
**Skill and Talent.** Robin's Skill, Pinion's Aria, increases the damage dealt by all allies by up to 50% for three turns, with the duration decreasing by one at the start of each of Robin's turns.[1](https://www.prydwen.gg/star-rail/characters/robin) Because the duration counts Robin's own turns rather than her allies', a single activation can remain active for a long time, which makes her efficient with Skill Points, the shared resource consumed by Skills.[1](https://www.prydwen.gg/star-rail/characters/robin) Her Talent, Tonal Resonance, increases all allies' CRIT DMG by up to 20% and regenerates 2 Energy for Robin each time an ally attacks an enemy target.[1](https://www.prydwen.gg/star-rail/characters/robin)
**Ultimate and Concerto.** Robin's Ultimate, Vox Harmonique, Opus Cosmique, costs 160 Energy, a high figure for the game's support characters.[1](https://www.prydwen.gg/star-rail/characters/robin) During Concerto, all allies' ATK increases by up to 22.8% of Robin's own ATK plus a flat 200, and after every attack by an ally, Robin deals Additional Physical DMG equal to up to 120% of her ATK, with a fixed CRIT Rate of 100% and fixed CRIT DMG of 150%.[1](https://www.prydwen.gg/star-rail/characters/robin) A countdown with a fixed Speed of 90 appears on the action bar; when its turn begins, Robin exits Concerto and immediately acts.[1](https://www.prydwen.gg/star-rail/characters/robin) While in Concerto she is immune to crowd control debuffs.[1](https://www.prydwen.gg/star-rail/characters/robin)
**Traces.** Robin's major traces reinforce the kit: A2 (Coloratura Cadenza) advances her own action by 25% at the start of battle, A4 (Impromptu Flourish) increases the CRIT DMG of all allies' follow-up attacks by 25% while Concerto is active, and A6 (Sequential Passage) regenerates an additional 5 Energy when she uses her Skill.[1](https://www.prydwen.gg/star-rail/characters/robin)
**Eidolons.** Her Eidolons, the duplicate copies obtained from pulling the same character again, add further Concerto effects: E1 grants all allies 24% All-Type RES PEN during Concerto, E2 raises allies' SPD by 16% and increases the Talent's energy regeneration by 1, E4 dispels crowd control from allies when the Ultimate advances them and raises their Effect RES by 50%, and E6 gives the Concerto's additional damage a 450% CRIT DMG increase for up to 8 triggers per Ultimate.[1](https://www.prydwen.gg/star-rail/characters/robin)
## Build and playstyle
Robin's stat requirements are unusual for a Harmony character. Because Concerto fixes her Speed at 90, she gains little from Speed investment beyond acting first in a fight, which her A2 trace makes easy to achieve; a Speed value of around 120 is generally sufficient.[1](https://www.prydwen.gg/star-rail/characters/robin) Since the Concerto attacks use fixed CRIT values, any CRIT stats she accumulates are wasted, so she cares almost exclusively about ATK, and defensive stats are a reasonable investment afterward.[1](https://www.prydwen.gg/star-rail/characters/robin) Her main drawback is energy: the 160-cost Ultimate, combined with regeneration that depends heavily on how often her teammates attack, makes her energy income inconsistent, and she is not friendly to the game's auto-battle mode, which may waste the action advance.[1](https://www.prydwen.gg/star-rail/characters/robin) The recommended build as of Version 4.6 pairs the Flowing Nightglow Light Cone with the Musketeer of Wild Wheat relic set.[3](https://www.hsr-build.com/characters/robin)
## Team compositions
**Follow-up attack teams.** Robin's strongest synergy is with characters whose kits trigger frequent follow-up attacks, such as Feixiao, Dr. Ratio, Topaz, and [Aventurine](https://www.edgepedia.org/aventurine).[1](https://www.prydwen.gg/star-rail/characters/robin) • [4](https://www.hoyolab.com/article/27887187) Every follow-up triggers her Concerto damage and her Talent's energy regeneration, and these characters also benefit from the A4 trace's 25% follow-up CRIT DMG boost, stacking with her Talent for a total of 45% CRIT DMG on follow-ups.[1](https://www.prydwen.gg/star-rail/characters/robin) [Community](https://www.edgepedia.org/community) guides describe her as dominant in follow-up attack compositions.[5](https://chjiya.github.io/sr-guide-en/guides/characters/robin.html)
**Other teams.** She is not restricted to follow-up teams. In hypercarry teams her 100% teamwide action advance lets the main damage dealer act more often, though characters such as Bronya and [Sparkle](https://www.edgepedia.org/sparkle-honkai-star-rail) retain an advantage because their action advance comes from their Skill rather than their Ultimate.[4](https://www.hoyolab.com/article/27887187) She also fits damage-over-time teams such as the classic Kafka and Black Swan pairing, where the team's frequent attacks and heavy ATK buffs raise DoT damage substantially.[1](https://www.prydwen.gg/star-rail/characters/robin) Simulation-based analysis around her release found that in an Argenti party her inclusion improved performance by roughly 1.5 to 1.6 times compared with existing parties.[6](https://vortexgaming.io/en/postdetail/1255797)
## Reception and later versions
Community polls have consistently ranked Robin among the best overall supports in the game alongside Ruan Mei, with the edge in teams built around follow-up attacks.[5](https://chjiya.github.io/sr-guide-en/guides/characters/robin.html) A version 4.5 summer-themed variant banner, Robin Summeretto, was announced through drip marketing alongside Aventurine Waveflair.[7](https://www.pcgamer.com/games/rpg/honkai-star-rail-banner-next-current/) The Summeretto version is a Wind Remembrance support who slots into almost any team, and as a [Remembrance](https://www.edgepedia.org/remembrance) character she gains a damage advantage alongside Remembrance allies such as Evernight.[8](https://allthings.how/robin-summeretto-best-teams-and-comps-in-honkai-star-rail/)
