Robin • Summeretto arrives in Honkai: Star Rail Version 4.5 on August 26, 2026, bringing a fresh Wind Remembrance take on Penacony’s beloved songstress. If she’s on your pull list, this Robin • Summeretto build guide covers her best Light Cones, Relics, stats, Eidolons, materials, team comps, and pull recommendations to get her stage-ready from day one.
Overview
|
Rarity: ★★★★★ |
Path: The Remembrance |
Element: Wind |
Robin • Summeretto is a 5-star Wind Remembrance support built to shine in teams that act often. Her kit revolves around building Vibes through frequent attacks, healing, and Shields, then maintaining Fever alongside her memosprite, Summer Songbirds. In practice, she brings strong teamwide offensive value through DEF ignore and other buffs, while adding respectable AoE damage of her own. She works especially well with ATK-scaling carries, but her kit is flexible enough to support other damage dealers too. With extra Action Advance and Energy support in her rotation, Robin • Summeretto is a powerful enabler for fast, action-heavy teams.

Skill Kit & Upgrade Priority
Basic ATK — The Sea Sings in My Key
Deals Wind DMG equal to 50% of Robin • Summeretto's Max HP to one enemy.
Skill — Summer Strums the Soul
Summons the memosprite "Summer Songbirds" Bessie. If any among the "Summer Songbirds" is already on the field, restores its HP by an amount equal to 100% of "Summer Songbirds's" Max HP, and gains 6 Vibes.
Ultimate — Ascend That Rhapsody in Blue
Advances the action of one designated ally unit (excluding Robin • Summeretto) by 100% and regenerates a fixed amount of Energy equal to 20% of their Max Energy, and then, grants them the "Special Guest" effect. When the character with "Special Guest" and their summon attacks, they additionally grant Robin 2 point(s) of Vibes and cannot advance the actions of other friendly targets. This effect lasts for 2 turn(s), and its duration decreases by 1 at the start of this character's turn.
Skill Upgrade Priority
Talent = Ultimate > Skill > Basic ATK
Prioritize Talent because leveling it directly strengthens Robin’s core Fever payoff, including the Songbirds’ scaling and the Zone’s DEF Ignore. Ultimate is equally important in practice, as stronger Energy restoration helps key allies reach their Ultimates sooner while its 100% Action Advance and Special Guest effect accelerate Vibes generation. Skill comes later because its most important functions—summoning Bessie and granting 6 Vibes on recast—already work regardless of level. Basic ATK only improves personal damage.

Light Cones
Signature Light Cone
Rise and Sing
Base HP: 1,164 Base ATK: 582 Base DEF: 396
Improvisation
Increases the wearer's Max HP by 30%. After the wearer uses their Ultimate, recovers 1 Skill Point for allies. When entering combat, advances the wearer's action by 30% and grants the wearer "New Melody" for 2 turn(s). While the wearer has "New Melody," all allies' SPD increases by 20%.
Rise and Sing perfectly complements Robin • Summeretto’s fast-tempo support loop. Its Max HP boost strengthens her HP-scaling damage and Songbirds, while the opening Action Advance lets her summon them sooner. New Melody raises team SPD, giving allies more actions to generate Vibes and reach Fever faster. After Robin uses her Ultimate, the Skill Point refund also helps keep Skill-heavy rotations running smoothly.
Alternatives
|
The Story's Next Page |
A strong 4-star option for ATK-scaling teams. Its Max HP increase improves Robin • Summeretto's HP-based ATK buff, making it one of her most practical lower-cost support choices when you skip the signature. |
|
The Flower Remembers |
A Battle Pass option that increases Robin's CRIT DMG and improves her memosprite damage. It is more personal-damage oriented than The Story's Next Page, but still fits teams where Robin can make good use of the extra offensive stats. |
|
Memory's Curtain Never Falls |
A reliable Herta Store option that provides SPD and a teamwide DMG boost. It is especially comfortable in teams whose main carry does not rely on ATK, where Robin values speed and general support utility more than extra Max HP. |
Other usable 5-star options: Long May Rainbows Adorn the Sky and To Evernight's Stars. Both can work, but their key effects do not stack and they are less universal, so they are not priority recommendations.

Relics
Recommended Relic Set
|
World-Remaking Deliverer |
Amphoreus, The Eternal Land |
|
World-Remaking Deliverer is Robin • Summeretto's standard 4-piece set. For Planar Ornaments, Amphoreus, The Eternal Land is the preferred general option because it supports the team's speed while fitting Robin's Remembrance playstyle. If you do not have her signature Light Cone or want a faster opening setup, Sprightly Vonwacq is a practical alternative thanks to its Energy Regeneration Rate and opening Action Advance. |

Build note: In teams whose carry does not benefit from ATK, keep the carry's ATK lower than Robin • Summeretto's so the carry receives her CRIT DMG branch instead of the ATK branch. If Robin's ATK ends up too low after gearing, an ATK Planar Sphere can be used as an adjustment.
Eidolons & Pull Recommendation
|
Stray Bird of Summer |
"Summer Songbirds" records 100% of the non-True DMG dealt by ally targets. When using the Memosprite Skill, it additionally deals True DMG equal to 11% of the total recorded DMG plus current Vibes points × 0.1% to the enemy target with the highest HP, then clears 50% of the recorded value. |
|
A Heart of Still Water |
Increases All-Type RES PEN of ally targets by 18%. Robin • Summeretto's Max Vibes increases by 20. The first time an ally target uses an ability that causes Robin • Summeretto to gain Vibes within any target's turn, she gains an additional 2 points. |
|
Echoes Left Along the Way |
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15. Memosprite Talent Lv. +1, up to a maximum of Lv. 10. |
|
Her Variation on the Theme |
Upon entering the "Fever" state, immediately gains 12 point(s) of Vibes, and the SPD of "Summer Songbirds" increases by 20% plus current Vibes × 0.5%. |
|
To Chase the Dawn Anew |
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10. Memosprite Skill Lv. +1, up to a maximum of Lv. 10. |
|
A Song Yet Unnamed |
Increases the Memosprite Skill's DMG multiplier by 100% of the original multiplier. While in the "Fever" state, Robin • Summeretto's Ultimate can be stored up to 2 times. After entering the "Fever" state for the first time or at the start of a "Fever" countdown turn in this battle, regenerates a fixed amount of 140 Energy. |
E1S0 — Good Stopping Point
E1 adds a strong True DMG component to Summer Songbirds based on damage dealt by the team, giving Robin a noticeable offensive upgrade without requiring her signature Light Cone. A solid stopping point for lower-investment players.
E2S0 — High-Value Investment
E2 is her biggest early vertical upgrade, granting allies 18% All-Type RES PEN while increasing Max Vibes and accelerating Vibes generation. This improves both team damage and Fever consistency, making E2 highly valuable even without her signature.
E2S1 — Best Overall ⭐
The recommended sweet spot. E2 provides powerful universal offensive buffs and smoother Vibes generation, while Rise and Sing adds Max HP, opening Action Advance, teamwide SPD, and an Ultimate-triggered Skill Point refund for a much smoother overall rotation.
E6S5 — Maximum Investment
For maximum performance, E6 dramatically upgrades Summer Songbirds’ damage and enables much more frequent Ultimate usage during Fever. Combined with S5’s stronger HP, Action Advance, and team SPD bonuses, it pushes both Robin’s support ceiling and personal output extremely high.
Investment Priority: E1S0 → E2S0 → E2S1 → E6S5
Team Comps
|
Himeko • Nova |
Robin • Summeretto |
Sunday |
Dan Heng • Permansor Terrae |
This team supports Himeko • Nova with two powerful action-focused supports. Robin • Summeretto contributes universal buffs, Vibes-based Fever uptime, single-target Action Advance, and Energy support, while Sunday helps Himeko cycle her key actions more smoothly. Dan Heng • Permansor Terrae fills the sustain slot and can repeatedly provide Shields to help Robin generate additional Vibes.
|
Castorice |
Evernight |
Robin • Summeretto |
Hyacine |
This team forms a tightly linked HP-and-memosprite loop. Frequent memosprite attacks and Hyacine’s healing continuously feed Robin’s Vibes, while Castorice’s HP consumption gives that healing constant value. Hyacine’s Max HP increase amplifies multiple HP-scaling kits, and Evernight’s memosprite CRIT DMG buff benefits nearly the entire team, pushing both damage and Robin’s Fever uptime.
|
Phainon |
Cyrene |
Robin • Summeretto |
Cerydra |
This setup concentrates everything into Phainon’s extended Transformation window. Cyrene accelerates Coreflame and strengthens Khaslana, while Cerydra’s Coup de Main duplicates his key transformed Skill. Meanwhile, Phainon’s repeated attacks continuously feed Robin • Summeretto’s Vibes, helping preserve Fever’s DEF Ignore and DMG Taken amplification throughout his burst sequence.
