Light Cone
Rise and SingRise and Sing is the unique best option: Max HP strengthens Robin and her songbirds, the opening advance accelerates setup, and the Ultimate refunds a Skill Point before granting team SPD.
When to use it : Open the battle with the signature's 30% action advance, then cast Ultimate on the carry while New Melody can convert its next actions into a teamwide 20% SPD window.
Memory's Curtain Never FallsMemory's Curtain Never Falls supplies 12% SPD and refreshes a three-turn team DMG bonus whenever Robin uses Skill, preserving the fast-support plan without her signature.
Memory's Curtain Never Falls and its superimpositions are permanently obtainable from Herta's Store without a limited Light Cone Warp.
Geniuses' GreetingsGeniuses' Greetings supplies ATK and strengthens the Basic ATKs of both wearer and memosprite after Ultimate.
When to use it : Use when the wearer and memosprite deal a meaningful share of their damage through Basic ATKs after Ultimate.
Relics
World-Remaking Deliverer gives CRIT Rate, raises the Max HP of Robin and her memosprite, and adds team amplification from the support slot.
When to use it : Keep a songbird summoned and alternate Skill or Basic as needed so the Max-HP and team-DMG effects do not lapse between Robin's actions.
Two-piece Messenger Traversing Hackerspace plus two-piece Guard of Wuthering Snow is a transition mix: Increases SPD by 6%. Reduces DMG taken by 8%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
Planar Ornaments
Amphoreus, The Eternal Land adds CRIT Rate to Robin and teamwide SPD while her memosprite is present, directly supporting her 160-SPD target and action-frequency teams.
When to use it : Keep a Summer Songbird on the field so the non-stacking 8% team SPD effect remains active throughout Fever.
Broken Keel is a ranked alternative with this two-piece effect: Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
When to use it : Reach 30% Effect RES to activate the teamwide CRIT DMG bonus.
Team lineup
Himeko • Nova and Dan Heng • Permansor Terrae supply frequent companion actions, Mortenax Blade amplifies every hit, and Robin converts that action density into Vibes, DEF ignore, advance and Energy.
When to use it : Use Robin's Ultimate on Himeko • Nova after the companion actions have built Fever; preserve Mortenax Blade's Zone and Dan Heng's protection through the burst window.

Robin • Summeretto summons Summer Songbirds, turns allied attacks and defensive actions into Vibes, then uses Fever to grant scaling DEF ignore before advancing and recharging one carry with her Ultimate.
How to play it
- 1Use Technique before combat for the opening action advance, 6 Vibes and the two-turn allied damage bonus.
- 2Cast Skill to summon the first Summer Songbird; recast only when the bird needs a full heal or the summon must be restored.
- 3Let allied attacks, healing and shielding build 6 then 12 Vibes so all three birds enter the field and trigger Fever.
- 4During Fever, target the main carry with Ultimate for a 100% action advance, 20% Max Energy restoration and the Special Guest effect.
- 5Maintain high team action frequency while Fever consumes Vibes, timing the next Skill and Ultimate before the bird cycle or carry burst loses momentum.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Prydwen and StarGuide were read independently for Robin • Summeretto's released equipment, stat targets, rotation and teams, then reconciled with Gachabase's released 4.5 kit and the exact local snapshot. The model treats every allied attack and the first heal or shield during a target's turn as one Vibe source, deploys the additional birds at 6 and 12 Vibes, and applies Fever's released DEF-ignore formula without crediting future actions. Ultimate advances only the selected carry by 100%, restores 20% of that ally's Max Energy and marks them as Special Guest. Equipment targets stop CRIT at 100% effective and use no unreleased 4.5 relic set.

Independent E0 recommendations based on the released Version 4.5 kit. SPD and CRIT targets include only the listed personal equipment effects; never build CRIT Rate beyond 100% in combat.
