Robin Build
Robin is a 5★ Physical character on the Path of Harmony in Honkai: Star Rail. Below are the character's stats, skills and Eidolons — plus a pity calculator if you plan to pull.
Robin is a top-tier Harmony support who buffs the whole team's ATK and CRIT DMG and grants everyone an extra turn.
Sub-stat priority: ATK% > SPD > CRIT DMG / Energy Regen
▾
Deals Physical DMG equal to 140% of Robin's ATK to one designated enemy target.
▾
Increase DMG dealt by all allies by 63%, lasting for 3 turn(s). This duration decreases by 1 at the start of Robin's every turn.
▾
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.
▾
Increase all allies' CRIT DMG by 27.5%. Moreover, after allies attack enemy targets, Robin additionally regenerates 2 Energy for herself.
▾
Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.
▾
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.
When the battle begins, action advances this character by 25%.
While the "Concerto" state is active, the CRIT DMG dealt when all allies launch Follow-Up ATK increases by 25%.
When using Skill, additionally regenerates 5 Energy.

Is Robin worth pulling?
Robin is a top-tier Harmony support who buffs the whole team's ATK and CRIT DMG and grants everyone an extra turn. Roll her if you own a strong carry (Feixiao, Dr. Ratio, any multi-target DPS); skip her if you mainly run Acheron/Nihility teams or lack a worthy carry.
What is the best team for Robin?
Feixiao and Dr. Ratio follow-up teams squeeze maximum value from her ATK buff and extra turn; a The Herta Pure Fiction team uses the extra action to wipe waves. Aventurine/Huohuo cover survivability and energy.

3★How to read this build page
Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.
Why the Light Cone and Relic picks make sense
Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.
- Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
- Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.
These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.
Trace/skill leveling order by role (a general guideline, not a fixed rule)
There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:
- DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
- Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
- Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
- Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.
Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.
Eidolons: how far E0 gets you, and which milestone is worth considering
General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.
How to think about SPD breakpoints
SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.
