The best Robin build in Honkai: Star Rail (Version 4.6) is Flowing Nightglow with Musketeer of Wild Wheat. Updated November 5, 2026
ATK% is the sole sub-stat that scales Robin's damaging and buffing kit as such stack as much of it as possible. While doing so it's recommended you ensure your Robin is fast enough alongside her action advance that she is always the first to act in combat. To guarantee this is always the case for almost all standard-built teams ensure she has 120-121 Speed. This will cover you even for fast compositions like 160-speed Sparkle (120 is good most of the time but if she's not first get a bit more). After stacking as much ATK as possible and satisfying your Speed needs, you can invest into Defence or invest into more Speed, although it is no longer essential after you've ensured Robin is moving first but can situationally still be helpful in certain teams and content.

Waveflair banks "Fervor" every time a teammate attacks and spends it on an all-enemy Elation Skill, so the team wants a second Elation unit feeding the counter, a Harmony buffer that adds actions, and a sustain that attacks on its own turn.

Flowing Nightglow tops the light cone ranking for Robin at S1, ahead of But the Battle Isn't Over, For Tomorrow's Journey and If Time Were a Flower. That order is prydwen.gg's, measured in play and rephrased here; every row of it sits under Light cones below.
Run Musketeer of Wild Wheat on Robin. The planar ornament is Sprightly Vonwacq. Main stats are ATK% body, ATK% feet, ATK% > Physical DMG sphere, Energy Regen Rate rope. Roll substats in the order ATK% >= SPD > HP% = DEF%.
Trace priority is Ultimate > Skill > Talent > Basic. The Ultimate costs 160 energy, which is what an Energy Regeneration Rate target has to clear.
Robin plays Action buffer in the Aventurine • Waveflair team, alongside Aventurine • Waveflair, Yao Guang and Huohuo.
