Honkai: Star Rail Robin build—The best relics and Light Cones

The best Robin build in Honkai: Star Rail is all about building attack for Penacony's pop star and prima donna. Like Luocha, Robin is a support character whose abilities scale with attack, meaning she can both deal a little damage and provide potent buffs to the entire party. Where she really shines is with her Vox Harmonique, Opus Harmonique ultimate, which causes her to enter the Concerto state.

As she belts out a song, every party member has their action advanced forward and receives a damage buff for a bout of musical murder.
