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.
The best Luocha build
Luocha is what you'd call an aggressive healer since, unlike Bailu or Natasha, his ability to heal scales with his attack as opposed to his HP. This makes him very strong, and able to both deal damage and heal the party at the same time. Ultimately, this means that buffing Luocha's Outgoing Healing stat doesn't provide as much value as simply buffing his attack, so you'll want to prioritise that.
- Light Cone: Echoes of the Coffin or Cornucopia
Luocha's five-star Echoes of the Coffin Light Cone is the best option for him, increasing his attack by 24% and granting allies 12 speed for one turn when he uses his ultimate. He also regenerates three energy for each different enemy he attacks, up to three times. Considering the ultimate in question targets every enemy, this is a pretty effective method of energy regen. The extra attack stat the light cone provides will also buff his healing.
There aren't any particularly great four-star Light Cones for Luocha, so for a less rare alternative I'd recommend the three-star Cornucopia. This Light Cone buffs Outgoing Healing by 12% when the character uses their skill or ultimate. Since Luocha creates healing Abyss Flowers with both of these abilities, this should provide a decent amount of value, especially as it'll be easier to superimpose it up to 24% considering its three-star rarity. It's true that four-star Light Cones have higher attack overall, so if you have a Quid Pro Quo or Shared Feeling hanging around it might be worth using, but in ability terms I think Cornucopia is the strongest of the less rare alternatives.
- Relics: Musketeer of Wild Wheat (Four-pieces equipped)
While the Passerby of Wandering Cloud set buffs Outgoing Healing, it's better to simply increase Luocha's attack, as this gives him both better healing and damage. Musketeer of the Wild Wheat increases attack by 12% for two-pieces and buffs speed by 6% and basic attack damage by 10% for four-pieces.
While Wastelander of Banditry Desert is an option for that 10% Imaginary damage boost, I think Musketeer is better for an attack buff, since that extra speed will help Luocha meet the secondary condition of the Space-Sealing Station ornament I'm recommending, granting him a further 12% attack. In terms of main relic stats, attack is a good shout, but you could also go with an Outgoing Healing on your chest. As mentioned, you also want to make sure Luocha is over 120 speed for that extra attack buff.
- Planar Ornaments: Space-Sealing Station (Two-pieces equipped)
The Space-Sealing Station set buffs attack by 12%, and a further 12% if you hit 120 speed. If you're using Echoes of the Coffin as your Light Cone, its speed buffing effect might help you do that, but otherwise Musketeer should help you reach it. Stat wise, I'd suggest Imaginary Damage Boost on the sphere, and either attack or energy regen on the link rope. All in all, this should help Luocha provide decent healing, damage, and ensure that he acts often to stack those Abyss Flowers.
