The best Honkai: Star Rail Luocha build centres around buffing the Abundance character's attack. Since Luocha's ability to heal scales with his attack, as opposed to his HP, this means he can both deal damage and heal your party. If that wasn't enough, his Abyss Flowers provide passive healing to allies when their health drops below a certain level, and he can even remove buffs from enemies with his Death Wish ultimate.
Honestly, Luocha is absurdly powerful; not just as a hybrid healer/damage-dealer, but as a character that can remove debuffs from allies if you unlock his Cleansing Revival bonus ability, and buff the attack of your whole party or provide a shield with his first two Eidolons. He's basically an Abundance, Nihility, and Harmony path character rolled into one powerful package. Here, I'll explain the Luocha build I recommend based on his kit, plus a list of his abilities, and ascension materials.
