Our Robin Build Guide will show you the best Light Cones, Relics, and team compositions to help you build the best Robin.

Robin's Best Light Cone

Listed below are the Light Cones we recommend for Robin.

Flowing Nightglow
S1

Every time an ally attacks, the wearer gains 1 stack of Cantillation. Each stack of Cantillation increases the wearer's Energy Regeneration Rate by 3.0 / 3.5 / 4.0 / 4.5 / 5.0%, stacking up to 5 time(s). When the wearer uses their Ultimate, removes Cantillation and gains Cadenza. Cadenza increases the Wearer's ATK by 48.0 / 60.0 / 72.0 / 84.0 / 96.0% and increases all allies' DMG dealt by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%, lasting for 1 turn(s).

Robin's BiS is her signature is Flowing Nightglow. Whenever an ally attacks, Robin gains a stack of Cantillation, increasing her Energy Regeneration Rate by 3% per stack, up to a maximum of five stacks. After Robin uses her Ultimate, all Cantillation stacks are consumed and replaced with Cadenza, which increases Robin's ATK by 48% and boosts all allies damage by 24% for one turn. This Energy Regeneration mechanic is especially valuable for Robin because it helps maintain high Ultimate uptime. The ATK increase is also highly beneficial, as it enhances both Robin's own Physical damage and the strength of the buffs she provides to allies, since her effects scale based on her ATK.

Past Self in Mirror
S1

Increases the wearer's Break Effect by 60.0 / 70.0 / 80.0 / 90.0 / 100%. When the wearer uses their Ultimate, increases all allies' DMG by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%, lasting for 3 turn(s). If the wearer's Break Effect exceeds or equals 150.0%, 1 Skill Point will be recovered. At the start of each wave, all allies regenerate 10 / 12.5 / 15 / 17.5 / 20 Energy immediately. Abilities of the same type cannot stack.

Sources: Event Warp (limited)

Past Self in Mirror increases Robins break effect by 60% at S1 and provides all allies with 10 energy at the start of every wave which is highly beneficial for keeping the uptime on Robin and her allies' ultimates. In addition to energy regen this light cone also increases all allies damage by 24% after Robin uses her ultimate and if her break effect is 150% or more 1 skill point is recovered.

For Tomorrow's Journey
S5

Increases the wearer's ATK by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. After the wearer uses their Ultimate, increases their DMG dealt by 18.0 / 21.0 / 24.0 / 27.0 / 30.0%, lasting for 1 turn(s).

Sources: Mission Reward

For Tomorrows Journey is a free to play light cone option for Robin if you don't own her signature. It provides Robin with increased attack by 32% at S5 and after she uses her ultimate it increases the damage she deals by 30% at S5.

But the Battle Isn't Over
S1

Increases the wearer's Energy Regeneration Rate by 10.0 / 12.0 / 14.0 / 16.0 / 18.0% 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 30.0 / 35.0 / 40.0 / 45.0 / 50.0% more DMG for 1 turn(s).

But the Battle Isn't Over is a 5-star light cone that provides Robin with increased energy regen rate by 10%. In addition when Robin uses her skill the next ally who takes their action deals 30% increased damage for that turn. This is a good choice if you lack the energy regen needed to keep the uptime on her ultimate.

Poised to Bloom
S5

Increases the wearer's ATK by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. Upon entering battle, if two or more characters follow the same Path, then these characters' CRIT DMG increases by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. Abilities of the same type cannot stack.

Sources: Event Warp (limited)

Poised to Bloom is another good choice for Robin which increases her attack by 16% and when entering battle if there are 2 more allies who follow the same path as herself then those allies Crit damage is increased by 16%. This is a good light choice if you are playing a team that includes multiple allies of the same path which does make it more of a circumstantial light cone choice.

Meshing Cogs
S5

After the wearer uses attacks or gets hit, additionally regenerates 4 / 5 / 6 / 7 / 8 Energy. This effect cannot be repeatedly triggered in a single turn.

Best Relics and Planar Ornaments for Robin

Best Relics for Robin

These are the best Relic sets for Robin.

Wavestrider Captain

2-Piece Set: Increases CRIT DMG by 16.0%.

4-Piece Set: When the wearer becomes the target of another ally target's ability, gains 1 stack of "Help," stacking up to 2 time(s). If there are 2 stack(s) of "Help" when the wearer uses their Ultimate, consumes all "Help" to increase the wearer's ATK by 48.0% for 1 turn(s).

Wavestrider Captain is a great option for Robin as it increases her overall Crit damage through the 2-piece but mainly for the focus of the 4-piece which increases her attack by a significant 48%. This set may be slightly difficult to use as Robin will need to be the target of another ally's ability twice making it dependent on the team she is in.

Hero of Triumphant Song

The Wind-Soaring Valorous

2-Piece Set: Increases ATK by 12.0%.

4-Piece Set: While the wearer's memosprite is on the field, increases the wearer's SPD by 6.0%. When the wearer's memosprite attacks, increases the wearer's and memosprite's CRIT DMG by 30.0%, lasting for 2 turn(s).

2-Piece Set: Increases ATK by 12.0%.

4-Piece Set: Increases the wearer's CRIT Rate by 6.0%. After the wearer uses a Follow-Up ATK, increases DMG dealt by Ultimate by 36.0%, lasting for 1 turn(s).

If you do not have or want to use Wavestrider then the only other options worth using for Robin are a 2-piece ATK with another 2-piece ATK or a 2-piece ATK with a 2-piece SPD but focusing on stacking as much attack is better.

Musketeer of Wild Wheat

Prisoner in Deep Confinement

2-Piece Set: Increases ATK by 12.0%.

4-Piece Set: The wearer's SPD increases by 6.0% and DMG dealt by Basic ATK increases by 10.0%.

2-Piece Set: Increases ATK by 12.0%.

4-Piece Set: For every DoT the enemy target is afflicted with, the wearer will ignore 6.0% of its DEF when dealing DMG to it. This effect is valid for a max of 3 DoTs.

Best Planar Ornaments

Lushaka, the Sunken Seas

2-Piece Set: Increases the wearer's Energy Regeneration Rate by 5.0%. If the wearer is not the first character in the team lineup, then increases the ATK of the first character in the team lineup by 12.0%.

Lushaka is a good choice for Robin as it provides her with increased energy regen rate by 5% and if she isn't placed as the ally in the first slot the attack of the ally in the first slot is increased by 12%.

Penacony, Land of the Dreams

2-Piece Set: Increases wearer's Energy Regeneration Rate by 5.0%. Increases DMG by 10.0% for all other allies that are of the same Type as the wearer.

Another good choice for Robin, increases her energy regen rate by 5% and the damage dealt by allies of the same element by 10%. This makes it slightly more restrictive to use if you want to use the full effects of the planar ornament but is still a good option for the extra energy regen rate nonetheless.

Sprightly Vonwacq

2-Piece Set: Increases the wearer's Energy Regeneration Rate by 5.0%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40.0% immediately upon entering battle.

Sprightly Vonwacq is a good choice as again it provides 5% energy regen but will require you to have Robin's SPD at 120 at least.

Fleet of the Ageless

2-Piece Set: Increases the wearer's Max HP by 12.0%. When the wearer's SPD reaches 120 or higher, all allies' ATK increases by 8.0%.

Robin Build Comments

Character Overview Team Overview

Character Explanation

Robin is a Harmony support character who excels at boosting her team's performance in battle while also contributing impressive damage herself. Her kit focuses on providing strong buffs, SP efficiency, and her powerful Ultimate, which immediately advances all allies' actions and places her into a Concerto state. During this state, Robin continuously adds extra Physical damage whenever allies attack, making her especially effective in fast-paced and follow-up attack teams. Unlike many supports, she scales mainly with ATK rather than Speed or CRIT stats making her surprisingly easy to build. Overall, Robin stands out as being one of the most flexible and strongest supports.

Team Overview

Robin is an incredibly flexible Harmony support who excels in aggressive, attack-focused teams thanks to her powerful team-wide buffs, action advancement and additional coordinated damage during her Ultimate. She performs especially well alongside characters who rely on frequent attacks or Follow-Up attacks, as her kit rewards fast-paced playstyles and constant offensive pressure. Robin also synergises strongly with allies that provide Energy regeneration, Skill Point support, shielding or healing, helping maintain high Ultimate uptime while compensating for her lower defensive and HP investment. Overall, Robin fits well into a wide variety of team compositions and can significantly enhance her team's overall damage output through the sheer amount of buffs and extra actions she provides.
