Should You Pull?YES

Yes for FUA/ATK teams—Robin’s Concerto advance is still premium. Ultimate “Vox Harmonique, Opus Cosmique” enters Concerto and action-advances every teammate. Best with Feixiao / Yunli / Clara / Topaz / Jade. 160-cost Ultimate; ERR and hits keep Concerto reliable. Skip when your teams are Break/DoT-only and won’t use Action Advance.

Robin is a 5★ Physical Harmony Support. Skill “Pinion's Aria” is the primary in-combat spend. Ultimate “Vox Harmonique, Opus Cosmique” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths

  • Ultimate “Vox Harmonique, Opus Cosmique” action-advances the whole team and opens a concerted damage window—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • Skill “Pinion's Aria” buffs allies’ damage for a short window—this is the spend that keeps the rotation honest.
  • Talent “Tonal Resonance” refunds a meaningful chunk of Energy inside the Skill—good play literally shortens Ult cooldown.
  • Learning when to hold vs spend “Pinion's Aria” is the difference between a clean Robin cycle and a wasted Skill Point.

Weaknesses

  • Buff windows on “Vox Harmonique, Opus Cosmique” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Robin’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
  • Spamming “Pinion's Aria” every turn without watching Skill Points strands the rest of the team—Robin is often the SP sink.
  • If “Vox Harmonique, Opus Cosmique” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.

General

Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.

Supports online

Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.

Light Cones

1
Flowing Nightglow

5★ · Path cone

Every time an ally attacks, the wearer gains 1 stack of Cantillation. Each stack of Cantillation increases the wearer's Energy Regeneration Rate by #1[f1]%, stacking up to 5 time(s). When the wearer uses their Ultimate, removes Cantillation and gains Cadenza. Cadenza increases the Wearer's ATK by 0.48% and increases all allies' DMG dealt by 0.24%, lasting for 1 turn(s).

Why it works —Signature / best-in-slot when owned—passive lines up with Robin’s kit triggers.

2
But the Battle Isn't Over

5★ · Path cone

Increases the wearer's Energy Regeneration Rate by 0.1% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.3% more DMG for 1 turn(s).

Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.

3
Carve the Moon, Weave the Clouds

4★ · Path cone

At the start of the battle and whenever the wearer's turn begins, one of the following effects is applied randomly: All allies' ATK increases by 0.1%, all allies' CRIT DMG increases by 0.12%, or all allies' Energy Regeneration Rate increases by 0.06%. The applied effect cannot be identical to the last effect applied, and will replace the previous effect. The applied effect will be removed when the wearer has been knocked down. Effects of the same type cannot be stacked.

Why it works —Best accessible option for most accounts—raise superimposition when copies drop.

4
Past and Future

4★ · Path cone

When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.16% increased DMG for 1 turn(s).

Why it works —Budget path cone—fine while building the account.

SupportPhysical
UltimateVox Harmonique, Opus Cosmique

Robin enters the "Concerto" state and makes all teammates (i.e., excluding this unit) immediately take action. While in the "Concerto" state, increases all allies' ATK by 26.6% of Robin's ATK plus 275. Moreover, after every attack by ally targets, Robin deals Physical Additional DMG equal to 144% of her ATK for 1 time, with a fixed CRIT Rate for this damage set at 100% and fixed CRIT DMG set at 150%. While in the "Concerto" state, Robin is immune to Crowd Control debuffs and cannot enter her turn or take action until the "Concerto" state ends. A "Concerto" countdown appears in the Action Order. When the countdown's turn begins, Robin exits the "Concerto" state and immediately takes action. The countdown has its own fixed SPD of 90.

SupportPhysical
TalentTonal Resonance

Increase all allies' CRIT DMG by 27.5%. Moreover, after allies attack enemy targets, Robin additionally regenerates 2 Energy for herself.

SupportPhysical
TechniqueOverture of Inebriation

After using Technique, creates a Special Dimension around the character that lasts for 15 seconds. Enemies within this dimension will not attack Robin and will follow Robin while the dimension is active. After entering battle while the dimension is active, Robin regenerates 5 Energy at the start of each wave. Only 1 Dimension Effect created by allies can exist at the same time.

E1Land of Smiles

While the "Concerto" state is active, all allies' All-Type RES PEN increases by 24%.

Is it worth getting?

Support comfort: Adds RES PEN (or ignore) during the burst window. E0 already does the job—E1 is luxury.

E2Afternoon Tea For Two

While the "Concerto" state is active, all allies' SPD increases by 16%. The Talent's Energy Regeneration effect additionally increases by 1.

Is it worth getting?

Stat-leaning E2: Flat combat-stat bump tied to a specific trigger. Clear damage, but it does not rewrite Robin’s rotation the way a mechanic eidolon would.

E3Inverted Tuning

Skill Lv. +2, up to a maximum of Lv. 15. Ultimate Lv. +2, up to a maximum of Lv. 15.

Is it worth getting?

Ultimate + Skill levels only (+2). Free if you roll into it; never spend currency aiming for E3.

E4Raindrop Key

When using the Ultimate, dispels Crowd Control debuffs from all allies. While Robin is in the "Concerto" state, increases the Effect RES of all allies by 50%.

Is it worth getting?

Side-grade: Pads Effect RES during the enhanced state. Happy if it drops; not a planned stopping point.

E5Lonestar's LamentSkip

Basic ATK Lv. +1, up to a maximum of Lv. 10. Talent Lv. +2, up to a maximum of Lv. 15.

Is it worth getting?

Talent + Basic ATK levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.

E6Moonless Midnight

While the "Concerto" state is active, the CRIT DMG for the Physical Additional DMG caused by the Ultimate increases by 450%. The effect of "Moonless Midnight" can trigger up to 8 time(s) and the trigger count resets each time the Ultimate is used.

Is it worth getting?

Whale ceiling: Flat combat-stat bump tied to a specific trigger. Only chase if Robin is your dedicated Harmony main and E0–E2 already feel finished.

Robin is fully usable at E0. Dedicated mains often stop at E0 before chasing higher. First stop: E0. Endgame target: E0.
