I have a confession: in 2026, with a roster full of shiny new healers and sustain units, I still keep Luocha in my first slot more often than I probably should. The foreign trader from beyond the stellar seas is not the flashiest five-star Imaginary character on the Abundance Path, but he is the pocket watch of Honkai Star Rail: he does not shout for attention, yet when a fight drags past midnight, his gears keep ticking. He heals, he cleanses, he generates skill points, and — because his healing scales with ATK rather than HP — he can even sting back. This guide is everything I wish I had known before I built him, updated for 2026 and based on the classic support-healer blueprint that still works today.

🛠️ Luocha's Best Build & Relic Sets

Most Abundance characters want HP. Luocha is not most Abundance characters. His healing comes from his ATK stat, which means every point of attack you give him is also a point of survival for your team. That makes him feel like a merchant's abacus: each bead you slide over is both profit and protection. I build him with ATK first, then SPD, then Effect RES, because a healer who is frozen or dominated is just a very expensive statue.

Best Relic Sets

Piece Set Why I Use It
4-Set Passerby of Wandering Cloud 2-piece gives 10% Outgoing Healing; 4-piece regenerates 1 Skill Point at battle start. Perfect for his healer role.
2-Set Fleet of the Ageless 12% Max HP, and at 120 SPD or higher, all allies gain 8% ATK. Protects Luocha and buffs the team.

For main stats and substats, I prioritize:

  • Body: Outgoing Healing Boost

  • Feet: SPD

  • Sphere: ATK%

  • Rope: Energy Regeneration Rate

  • Substats: ATK% > SPD > Effect RES > HP%

You want his ATK as high as possible, but do not ignore SPD. Faster turns mean more frequent heals and more chances to refresh his Talent field. Effect RES keeps him from being incapacitated, which is the quiet killer of many healer builds. In 2026, I still find this setup comfortable in Memory of Chaos, Apocalyptic Shadow, and most endgame modes where sustained healing matters more than burst.

💡 Luocha's Best Light Cones

Luocha's Light Cone choices revolve around two things: ATK and Outgoing Healing. He is usually the only healer on my team, so I treat his cone like a field medic's kit — it must be reliable, not fancy.

Rarity Light Cone Effect My Verdict
5-Star Echoes of the Coffin +24% ATK. After attacking, regenerates 3 Energy per different enemy hit (up to 3 times). After Ultimate, all allies gain 12 SPD for 1 turn. His signature and best option. It buffs healing through ATK, fuels his Ultimate, and gives team speed.
4-Star Post-Op Conversation +8% Energy Regeneration Rate; +12% Outgoing Healing after Ultimate. A solid alternative. Keeps his Energy high and his heals efficient.
3-Star Cornucopia +12% Outgoing Healing when using Skill or Ultimate. The best starter option if you lack 4-star or 5-star Abundance cones.

Echoes of the Coffin is not just damage — it is tempo. The Energy refund after multi-target attacks makes his Ultimate come back faster, and the SPD buff after Ultimate can flip an entire turn order. If you do not have it, Post-Op Conversation is the workhorse I recommend. Cornucopia is fine while you are still farming, but I would not stay there forever.

🧩 Luocha's Best Team Compositions

Luocha is a Support Healer, so he fits into many teams. His Talent places a field that heals allies for two turns, which means he loves teammates with high SPD who can take extra turns inside that field. His field is like a moonflower that blooms only when your team is bleeding out, then folds away before the enemy can step on it. I like pairing him with:

  • High-SPD Harmony characters who can push the team forward and benefit from his healing field.

  • Hypercarry DPS units that want a skill-point-positive healer so they can keep using their Skills.

  • Debuffers and sub-DPS units who appreciate his cleanse and emergency heal.

In my own runs, I often place him with a fast Harmony unit and a main damage dealer. Because Luocha can heal without spending Skill Points every turn, he gives the rest of the team room to breathe. That is rare, and in 2026 it is still valuable. Newer sustain characters may offer shields, follow-up attacks, or bigger numbers, but Luocha's auto-healing field and emergency cleanse remain a comforting safety net.

⚖️ Final Thoughts: Is Luocha Still Worth Building in 2026?

Yes — with caveats. If you already own him, he is a low-maintenance investment who rewards ATK, SPD, and Effect RES. If you are pulling fresh in 2026, I would not chase him over every new limited sustain, but I would never call him wasted. He is like a violin string: you tighten ATK instead of HP, and the whole orchestra of survival stays in key. Build him with Passerby of Wandering Cloud, Fleet of the Ageless, and a good Abundance Light Cone, and he will keep your team alive while quietly contributing damage of his own. For me, that trade is still worth it.
