Robin returns in Honkai: Star Rail Version 4.5 as Robin • Summeretto, a separate 5-Star playable form that changes her original Physical Harmony kit into a Wind character on the Path of Remembrance.
This guide walks through her full kit, best Light Cones and Relics, team compositions, Eidolon value, and a pre-farm checklist so your account is ready when her banner opens.
If you are already saving for Version 4.5, planning your Oneiric Shard budget early can help. Honkai: Star Rail top-up on GamsGo can cost less than the in-app price, which may leave more room in your budget for Robin • Summeretto and her signature Light Cone.
Every number below comes from the Version 4.5 closed beta and is cross-checked against the current datamine. Multipliers, names, and mechanics can still shift before launch.
HoYoverse's 4.5 Special Program, "To Roll the Stars in Astropolis," airs August 14, 2026, so official values are imminent. We will refresh this page once she goes live.
Robin Summeretto Character Overview
Robin • Summeretto is built around Max HP, a resource called Vibes, and her memosprite Summer Songbirds. Her HP directly affects her Basic ATK, the Songbirds' HP and damage, and the flat ATK bonus from Deviated Chords when that branch of the Trace is triggered.
Her rotation is about bringing all three Songbirds onto the field, entering Fever, and keeping enough Vibes available for their repeated AoE attacks. During Fever, Robin does not take normal turns, while the team gains DEF ignore from her Zone and enemies take more damage based on how many Songbirds are present.

Here is the fast reference. Full reasoning for every pick follows further down.
Robin Summeretto Trace Priority
Current beta upgrade order: Ultimate > Memosprite Skill > Memosprite Talent > Skill > Talent > Basic ATK.
| Priority | Trace | Why |
|---|---|---|
| 1st | Ultimate | Core support button: 100% action advance, Energy restoration, and Special Guest for extra Vibes. |
| 2nd | Memosprite Skill | Direct AoE damage from Summer Songbirds, reaching 150% of their Max HP at the displayed max level. |
| 3rd | Memosprite Talent | Controls Fever damage amplification, enemy DMG taken, Songbird actions, and Vibes consumption. |
| 4th | Skill | Summons Bessie; later uses heal an existing Songbird and add 6 Vibes. |
| 5th | Talent | Defines Songbird stats, Vibes generation, Fever entry, and the Zone's DEF-ignore effect. |
| 6th | Basic ATK | Useful for Skill Point generation, but lowest priority in the current build guide. |
Robin Summeretto Kit Breakdown
Robin • Summeretto revolves around Vibes, Summer Songbirds, and the Fever state. The important detail is that not every action generates Vibes in exactly the same way: ally attacks generate Vibes, while healing or shielding is limited to the first qualifying instance in a target's turn.
| System | How It Works | Why It Matters |
|---|---|---|
| 🎵 Vibes | Max 50 at E0. Ally attacks grant 1 Vibe. A healing or Shield effect can also grant Vibes when it is the first qualifying instance in a target's turn. The Ultimate's Special Guest generates 2 extra Vibes when that character or their summon attacks. | Vibes determine when Drummie and Paddie appear and scale Robin's Fever Zone, Memosprite damage bonus, and Deviated Chords buff. |
| 🐦 Summer Songbirds | Bessie comes from Skill. With Bessie present, Drummie is summoned at 6+ Vibes and Paddie at 12+ Vibes. Their initial Max HP equals 70% of Robin's Max HP and their initial SPD equals 180% of Robin's SPD. | Having 1/2/3 Songbirds on the field makes all enemies take 8%/12%/16% more DMG. |
| 🌞 Fever & Zone | Fever starts when all three Songbirds are on stage. Robin and the Songbirds become immune to Crowd Control, and Robin stops entering normal turns until Fever ends. | Allied damage inside the Zone ignores 15% + Vibes × 0.5% of enemy DEF, reaching 40% at 50 Vibes. |
⚔️ Basic ATK — The Sea Sings in My Key
Deals Wind DMG to one enemy equal to 50% of Robin's Max HP. It generates 20 Energy and 1 Skill Point.
🗡️ Skill — Summer Strums the Soul
Summons Summer Songbird Bessie. If a Summer Songbird is already on the field, the Skill instead restores HP equal to 100% of the Songbirds' Max HP and grants Robin 6 Vibes. This distinction matters: the initial Bessie summon itself is not described as granting those 6 Vibes in the current beta text.
💥 Ultimate — Ascend That Rhapsody in Blue
Selects one ally other than Robin, advances that ally's action by 100%, and restores Energy equal to 20% of their Max Energy. The target then receives Special Guest for 2 turns. Whenever that character or their summon attacks, Robin gains 2 additional Vibes. While Special Guest is active, that character cannot advance the actions of other friendly targets.
🧬 Talent — Wings Heed No Borders
Summer Songbirds start with Max HP equal to 70% of Robin's Max HP and initial SPD equal to 180% of Robin's SPD. Ally attacks give Robin 1 Vibe, and healing or shielding can also generate Vibes under the Talent's per-turn condition, up to 50 Vibes at E0.
With Bessie on the field, reaching 6 Vibes summons Drummie and reaching 12 Vibes summons Paddie. Once all three are present, Robin and the Songbirds dispel Crowd Control from themselves, enter Fever, and create a Zone. While allies deal damage inside the Zone, they ignore 15% + Vibes × 0.5% of the target's DEF.
🎵 Technique — We Are the Melody
At the start of the next battle, Robin's action advances by 20%, she immediately gains 6 Vibes, and all allies gain 30% increased DMG for 2 turns. This is the cleanest way to begin a fight with Vibes already available.
🐦 Memosprite Skill — Chirrup Quartet
Summer Songbirds deal Wind AoE DMG equal to 150% of their Max HP to all enemies at the displayed max level.
✨ Memosprite Talent — A Warble of Wings
During Fever, Robin and the Summer Songbirds gain a DMG bonus equal to 60% + Vibes × 2%. The action-bar countdown has an initial SPD of 140. When the Songbirds' turn begins, they use Chirrup Quartet and then remove 50% of current Vibes, with at least 12 Vibes deducted. When Vibes falls to 0, the Songbirds disappear and Robin exits Fever.
- Enemy DMG taken: 1/2/3 Songbirds increase DMG taken by all enemies by 8% / 12% / 16%.
- Near the Sea's Heartbeat: summoning the Summer Songbirds restores 20 Energy to Robin.
- Astride Summer's Nightwind: when the Summer Songbirds disappear, Robin's action advances by 50%.
🔑 Key Traces
| Trace | Effect |
|---|---|
| Deviated Chords | When an ally causes Robin to gain Vibes, compare that ally's ATK with Robin's. If the ally's ATK is higher, they gain a flat ATK bonus equal to (16% + Vibes × 0.4%) of Robin's Max HP. Otherwise, they gain 40% + Vibes × 1.5% CRIT DMG. The buff lasts 2 turns. |
| Improvised Blues | When Robin or the Summer Songbirds receive healing or a Shield from teammates, Robin gains 12 Groove, up to 12. The first time she gains Vibes in any unit's turn, 1 Groove is consumed to restore 3 Energy. |
| Rebuilt Harmony | Robin and Summer Songbirds gain +50% CRIT Rate. |
Her minor Traces add +18% HP, +14 SPD, and +7% CRIT Rate in total.
Best Light Cones for Robin Summeretto
Signature: Rise and Sing (5-Star Limited)
Rise and Sing is the most complete option because every part of its passive contributes to Robin's rotation: Max HP improves her scaling, the opening action advance helps establish Bessie earlier, the team SPD buff increases overall action frequency, and the Skill Point refund offsets some of the cost of repeatedly using Skill outside Fever.
Alternative Light Cones
If you skip Rise and Sing, choose between To Evernight's Stars for stronger wearer/memosprite scaling and Memory's Curtain Never Falls for SPD plus a team DMG buff after Skill.
| Light Cone | Why It Works |
|---|---|
| To Evernight's Stars | Adds Max HP, boosts damage dealt by the wearer and their memosprite, lets allied memosprites ignore DEF while Noctis is active, and restores Energy when the wearer's memosprite disappears. |
| Memory's Curtain Never Falls | Increases the wearer's SPD and, after Skill is used, increases all allies' DMG for 3 turns. |
Best Relics for Robin Summeretto
Robin Summeretto Main Stats & Substats
- Body: HP% > CRIT DMG
- Feet: SPD > HP%
- Planar Sphere: HP% > Wind DMG Boost
- Link Rope: Energy Regeneration Rate > HP%
- Recommended substats: CRIT Rate / CRIT DMG / HP% / SPD
Max HP is the core scaling stat, but the current build guide still lists CRIT Rate among useful substats. Rebuilt Harmony already adds 50% CRIT Rate and her minor Traces add another 7%, so you generally do not need to force a CRIT Rate Body, but extra CRIT Rate can still improve consistency depending on your final set and rolls.

Best Robin Summeretto Team Comps
The single rule that shapes her teams: she wants frequent ally actions. Follow-up attacks, out-of-turn heals, and extra memosprite actions all feed her Vibes counter, so the more your team acts outside its own turns, the higher and steadier her buffs sit.
Recommended Team 1: Himeko • Nova Core
| Slot 1 | Slot 2 | Slot 3 | Slot 4 |
|---|---|---|---|
Robin • Summeretto  | Himeko • Nova  | Mortenax Blade  | Dan Heng • Permansor Terrae  |
Himeko • Nova's beta kit gives allies access to Assist Skill attacks, creating additional attack events that fit Robin's Vibes-based design. The exact rotation can still change while both beta kits are being tuned.
Recommended Team 2: Remembrance Core
| Slot 1 | Slot 2 | Slot 3 | Slot 4 |
|---|---|---|---|
Robin • Summeretto | Castorice  | Cyrene  | Hyacine  |
The second listed lineup keeps Robin inside a Remembrance-heavy team. Hyacine is especially compatible with Robin's resource system because Robin can gain Vibes from qualifying healing events, while the rest of the team benefits from her Fever Zone, enemy DMG-taken debuff, and Deviated Chords.
Recommended Team 3: Aventurine • Waveflair Core
| Slot 1 | Slot 2 | Slot 3 | Slot 4 |
|---|---|---|---|
Robin • Summeretto | Aventurine • Waveflair  | Mortenax Blade | Hyacine |
Beta caution: Several members are beta or newly released characters, so treat the ordering as a pre-release recommendation rather than a permanent meta ranking.
Robin Summeretto Eidolons Breakdown
E0 already contains her complete Vibes, Summer Songbirds, Fever, and Zone loop. Her Eidolons mainly increase team amplification, Vibes capacity, Songbird speed, and high-investment damage.
| Eidolon | Icon | Effect | Build Value |
|---|---|---|---|
| E1 — Stray Bird of Summer |  | Summer Songbirds record 100% of allies' non-True DMG. When they use Memosprite Skill, they deal extra True DMG equal to (11% + current Vibes × 0.1%) of the recorded amount to the highest-HP enemy, then remove 50% of the stored record. | Adds a new source of team-driven True DMG. |
| E2 — A Heart of Still Water |  | All allies gain 18% All-Type RES PEN. Max Vibes rises by 20 to 70. The first ally ability in a target's turn that causes Robin to gain Vibes gives an extra 2 Vibes. | Major support breakpoint. At 70 Vibes, her Zone can reach 50% DEF ignore. |
| E3 — Echoes Left Along the Way |  | Skill +2, Talent +2, Memosprite Talent +1. | Numerical upgrade. |
| E4 — Her Variation on the Theme |  | Entering Fever immediately grants 12 Vibes. Summer Songbirds gain SPD equal to 20% + current Vibes × 0.5%. | Faster Songbird tempo and easier Fever resource management. |
| E5 — To Chase the Dawn Anew |  | Ultimate +2, Basic ATK +1, Memosprite Skill +1. | Numerical upgrade. |
| E6 — A Song Yet Unnamed |  | Doubles the Memosprite Skill multiplier by adding 100% of its original multiplier. During Fever, Robin can store up to 2 Ultimate uses. The first Fever entry and the start of Fever countdown turns restore a fixed 140 Energy. | Huge capstone for Songbird damage and Ultimate frequency. |
If you are judging only the current beta kit, E2 is the clearest support-oriented stopping point because it combines team RES PEN, a higher Vibes ceiling, and faster Vibes generation. E1 is more damage-focused.

Should You Pull for Robin Summeretto?
Based on the current beta kit, Robin • Summeretto is most attractive if your account can make use of her Vibes engine and the three recommended team structures above. Her value comes from stacking several effects at once rather than from one universal full-team action advance.
| 🚀 Pull if | 🛑 Consider skipping if |
|---|---|
| You are building one of the current recommended cores around Himeko • Nova, Castorice/Cyrene, or Aventurine • Waveflair. | Your main teams do not generate many attacks, heals, or shields and would struggle to keep Vibes available. |
| You want a support who combines DEF ignore, increased enemy DMG taken, ATK/CRIT DMG buffs, action advance, and Energy restoration. | You specifically want the original Robin's full-team action advance; Summeretto's Ultimate advances only one selected ally. |
| You already have Remembrance or summon-focused units that can benefit from her current recommended gear and team environment. | You would need to rebuild an entire team just to make her Vibes loop function smoothly. |
Conclusion
Robin Summeretto brings a fresh Remembrance playstyle to Honkai: Star Rail, with a build centered on her Summer Songbirds, Vibes, and team support. Since her current information is still based on beta data, some details may change before release.
GamsGo will continue covering the latest Honkai: Star Rail updates, banners, character builds, codes, and guides, so check back for the final Robin Summeretto build once Version 4.5 goes live.
FAQ About Robin Summeretto
When Does Robin Summeretto Release?
She is expected in Version 4.5 Phase 1, opening around August 25, 2026 for the NA server and August 26 for EU and Asia. HoYoverse's 4.5 Special Program on August 14, 2026 should confirm the exact dates.
Is Robin Summeretto a Skin or a New Character?
She is a separate playable character, not a cosmetic skin for the original Robin. This version is a 5-Star Wind Remembrance character with a completely different kit centered on Summer Songbirds and Vibes.
Is Her Signature Light Cone Worth Pulling?
It is not mandatory, but Rise and Sing solves two real problems: it refunds a Skill Point after her Ultimate and gives her an opening action advance for a smoother first summon. To Evernight's Stars and the Herta Shop cone are strong stand-ins if you skip it.
What Is the Best Relic Set for Robin Summeretto?
The current recommended combination is World-Remaking Deliverer (4-PC) with Amphoreus, The Eternal Land (2-PC). Sacerdos' Relived Ordeal and Messenger Traversing Hackerspace are listed as Cavern alternatives, while Sprightly Vonwacq and Lushaka, the Sunken Seas are alternative Planar sets.
What Main Stats Should Robin Summeretto Use?
The current build guide recommends HP% over CRIT DMG on Body, SPD over HP% on Feet, HP% over Wind DMG Boost on Sphere, and Energy Regeneration Rate over HP% on Rope. Recommended substats are CRIT Rate, CRIT DMG, HP%, and SPD.
Which Robin Summeretto Eidolon Is the Best Stopping Point?
For support value, E2 is the standout in the current beta: it gives allies 18% All-Type RES PEN, increases Max Vibes from 50 to 70, and accelerates Vibes generation. E1 is more focused on adding True DMG through the Summer Songbirds.
