Honkai: Star Rail Best Robin Build

After much anticipation and excitement, the beloved superstar Robin has finally debuted in Honkai: Star Rail. Crafting the optimal build for her is a straightforward task, thanks to her unique kit.

Strongest Robin Build in Honkai: Star Rail

Robin is a Physical Harmony character whose main role on any given team is to buff the DMG% of her allies through her Skill. Uniquely to Robin, and her primary counterpart Ruan Mei, she can buff her whole team instead of just one ally, which is uncommon for Harmony Supports.

What sets Robin apart from the rest of the Harmony roster is her Ultimate, which provides a staggeringly powerful team-wide Advance Forward when activated. This allows teams with Robin on them to perform some truly creative strategy not available anywhere else in the game.

Robin’s Ultimate has a second significant mechanic attached to it after activation. While her Ultimate is active, when any teammates launch an attack, Robin provides a secondary instance of Physical Damage to one of the struck targets. This mechanic has no attack limit meaning Robin plays best with characters that can attack very often.

Best Relics for Robin

Despite being a Harmony character, an archetype notorious for needing various groups of stats to perform well, Robin really only needs ATK% and nothing else. You read that correctly. Robin doesn’t need, HP%, DEF, or any other stat other than ATK%, as everything she does scales off it.

While Robin doesn’t need Speed, due to her SPD stat being fixed during her Ultimate, getting her to 120 SPD is ideal as it allows her to use sets that require that amount. As you can see, though, Robin is straightforward to build. With this in mind, the best Relics for Robin will be any combination that provides ATK%.

You can use a 2-piece Prisoner in Deep Confinement and 2-piece Musketeer of Wild Wheat as both Relic set bonuses provide unconditional ATK%. Additionally, if you’d prefer your Robin to be more supportive of your team, you can run a 4-piece Messenger Traversing Hackspace for the teamwide speed boost, though you will be losing out on damage for both your team and Robin.

For Robin’s Sphere and Rope set, use the Space Sealing Station set with an Energy Regeneration rope. You want to make sure your rope has Energy Regeneration as its core stat because her Ultimate is one of the most expensive Ultimate costs in the game. Also, make sure your Robin has 120 SPD so she gets the additional ATK% buff that comes from the secondary portion of the set bonus.

Best Team Comp Robin

Like Ruan Mei, Robin can fit on any team comp in need of Harmony Support due to the potent buff she provides with her Skill. However, Robin’s best Team Comp is a Follow-up one for a few reasons.

Thanks to her Talent, Impromptu Flourish, Robin provides an additional 25% CRIT DMG (Critical Damage) to Follow-up attacks. Pretty straightforward. The other reason is due to her steep Ultimate energy cost. Thanks to her other important Talent, Tonal Resonance, Robin gets a small amount of Energy back every time an ally launches an attack, making frequent attackers more useful to Robin. With that said, Topaz and Numby, Dr. Ratio, and Aventurine are Robin’s best teammates.

Topaz and Numby attacks more often than any other character in Honkai: Star Rail, making her the ideal teammate for Robin. Robin buffs up Follow-up attacks, making them completely compatible with each other.

Dr. Ratio often attacks in conjunction with Topaz and Numby, making him a frequent attacker as well. Every attack he launches restores Energy to Robin, allowing her to maintain her Ultimate longer. Finally, Robin’s specific buffs toward Follow-up attacks make him an ideal teammate for her.

Aventurine’s Follow-up mechanic is tied to the number of Follow-up attacks his teammates launch, as well as, how often they are hit while his shield is active. Aventurine attacks almost as often as Topaz and Numby thanks to this, so, naturally, Robin gains all the same benefits from him as well.

Should you get Robin’s Lightcone in Honkai: Star Rail?

Without a doubt, Robin’s Lightcone, Flowing Nightglow is the ideal Lightcone for her playstyle. Not only does it greatly boost her own damage, but also provides additional buffs to the rest of her teammates. However, what’s really important about this Lightcone is the Energy Regeneration it provides Robin. The point of using Robin is to make sure her Ultimate is up and active as much as possible. Without the extra generation of this Lightcone, Robin will struggle to maintain uptime on teams that do not have Follow-up attacks on them.

That said, Robin does have a strong alternative Lightcone. But the Battle Isn’t Over is Robin’s second-best Lightcone because it also has Energy Regeneration on it. At Superimposition 2, it is nearly equal to Robin’s signature Lightcone in terms of Energy Regen. If you don’t have But the Battle Isn’t Over, I recommend you pull Flowing Nightglow to make full use of your Robin.

Best Eidolons for Robin in Honkai: Star Rail

At E0, Robin is a powerhouse of a character, and her Eidolons do not greatly impact the functionality of her character. As with all characters though, her Eidolons do make her stronger. If you’re interested in grabbing her Eidolons, the best stopping point would be E1. For your reference, here are her six Eidolons.

• Land of Smiles (E1) – While her Ultimate is active, all her allies get All-Type RES PEN increased by 24%. This is strong for all teams, but stronger for teams fighting off-element enemies. Strong Eidolon.
• Afternoon Tea for Two (E2) – While her Ultimate is active, all allies gain 16% SPD, and Robin regenerates an extra point of Energy per attack, equally three Energy total. Decent, but hardly required
• Inverted Tuning (E3) – Skill and Ultimate Level increases by two. Stronger buffs, more damage. Not required.
• Raindrop Key (E4) – When her Ultimate is activated, she dispels all debuffs from your team and provides a 50% Effect Resistance buff. Extremely lackluster Eidolon as dispels should be covered by your sustainer anyway.
• Lonestar’s Lamet (E5) – Basic ATK and Talent Level increase by two. Basic ATK is useless on Robin and the Talent buff is nice, but not noticeable enough to matter.
• Moonless Midnight (E6) – Her first eight additional attacks during each use her Ultimate, get 450% CRIT DMG. This Eidolon is stupidly strong and is worth it if you can get it. Robin will easily out-damage all of your DPS with this Eidolon.
