Luocha Build, Light Cones & Teams | Honkai: Star Rail

Alexa Hunter

Feb 18, 2026

Luocha is one of the comfiest 5-star sustains in Honkai: Star Rail whose whole kit is built around his "Abyss Flower" field. This field gives your team lifesteal, so as long as you're attacking, nobody dies. Combine that with his free emergency auto-heal and an Ultimate that wipes buffs off enemies, and you have a totally SP-positive unit that fits into literally any team. This Luocha build guide will walk you through his best relics, Light Cones, and how to stack enough ATK to make your team practically invincible.

Luocha Character Overview

Luocha's kit is defined by his Abyss Flower field, which grants the entire team "lifesteal," effectively letting the DPS units heal themselves to full just by landing hits. Luocha is also the king of comfort thanks to his passive auto-heal, which instantly tops off any ally who drops below 50% HP without costing a single Skill Point or interrupting your rotation. Since his healing scales entirely off ATK, he hits surprisingly hard for a support, and his Ultimate brings massive utility by stripping annoying buffs off all enemies. Combine this with his ability to generate endless Skill Points since he rarely needs to use his manual Skill, and you have the ultimate "plug-and-play" sustain who keeps your team immortal while letting your carries go wild.

Luocha Trace Priority

Trace	Priority
Skill	★★★★★ (Top)
Talent	★★★★★ (Top)
Ultimate	★★★ (Mid)
Basic ATK	★ (Low)

Luocha’s Skill and Talent are the top priority, because they dictate how much HP he restores. The Skill powers up his auto-heal, and the Talent boosts the "lifesteal" your team gets from his field.

Luocha’s Ultimate takes a backseat. It’s fantastic for the AoE Buff Removal, but here’s the thing: that utility works the same at Level 1 as it does at Level 10. Leveling it only boosts his personal damage, so don’t stress about maxing it unless you have extra resources lying around.

Luocha’s Basic ATK is the lowest priority. You’re only using it to generate Skill Points, so the damage scaling is negligible. Instead, focus on unlocking his Bonus Traces like Cleansing Revival, which lets his Skill remove debuffs from allies, a massive quality-of-life upgrade.

Luocha Best Light Cones

To select the ideal Light Cone for Luocha, evaluate your build against these three tactical needs rather than simply choosing by rarity:

Meeting the High ATK Threshold: Unlike other healers who stack HP, Luocha’s healing scales entirely off ATK. You want to aim for at least 2,500+ ATK to make his auto-heals meaningful. If your relics are lacking offensive stats, prioritize Light Cones with high base ATK like his signature Echoes of the Coffin to ensure his healing output doesn't fall behind.
Optimizing Field Uptime: His "lifesteal" field is his strongest asset, but it only lasts for 2 turns. You need Energy Regeneration to cycle his Ultimate faster, which helps reset the field's duration and keeps the auto-healing active. Light Cones like Post-Op Conversation or Shared Feeling are excellent here because they help you spam his Ultimate more often.
Supporting Team Skill Point (SP) Economy: Luocha is already the king of SP generation, but you can push this even further. If your team is SP-hungry (like with Daniel or Seele), consider using the 3-star Light Cone Multiplication. It makes him move incredibly fast, letting him generate endless Skill Points and refresh his emergency heal cooldown constantly.

1. 5-Star Options

Luocha's best Light Cone is Echoes of the Coffin, which provides a massive 24% ATK boost right out of the gate to scale his healing. It’s a utility monster that solves all his needs: it regenerates Energy every time he attacks to keep his uptime perfect, and after he uses his Ultimate, it grants a 12 SPD boost to the entire team—helping everyone cycle faster.

Best Choice

Echoes of the Coffin

ATK: 582 | DEF: 1164 | HP: 1164

S1: Increases the wearer's ATK by 24%. After the wearer uses an attack, for each different enemy target the wearer hits, regenerates 3 Energy. Each attack can regenerate Energy up to 3 time(s) this way. After the wearer uses their Ultimate, all allies gain 12 SPD for 1 turn.

2. Alternative Options

Alternative Choice
Perfect Timing	ATK: 423 \| DEF: 396 \| HP: 952 S5: Increases the wearer's Effect RES by 32% and increases Outgoing Healing by an amount that is equal to 45% of Effect RES. Outgoing Healing can be increased this way by up to 27%.
Quid Pro Quo (S5)	ATK: 423 \| DEF: 396 \| HP: 952 S5: At the start of the wearer's turn, regenerates 16 Energy for a randomly chosen ally (excluding the wearer) whose current Energy is lower than 50%.
Unto Tomorrow's Morrow	ATK: 476 \| DEF: 396 \| HP: 1058 S5: Increases the wearer's Outgoing Healing by 24%. When an ally target's current HP percentage is greater than or equal to 50%, increases the DMG dealt by 20%.
Shared Feeling	ATK: 423 \| DEF: 396 \| HP: 952 S5: Increases the wearer's Outgoing Healing by 20%. When using Skill, regenerates 4 Energy for all allies.

Ruan Mei Relics, Ornaments & Stats Priority

1. Relics

Warrior Goddess of Sun and Thunder: Best-in-Slot. The new offensive meta. It grants free SPD, and the 4-piece bonus buffs team CRIT DMG whenever he heals—turning him into a pseudo-Harmony buffer.

Alternatives Choices

Messenger Traversing Hackerspace: Utility Pick. Best for speed-tuning. It boosts team-wide SPD after he uses his Ultimate, helping your squad lap the enemy.
Musketeer of Wild Wheat: The Reliable Standard. A simple stat stick giving ATK and SPD. Use this if you lack good pieces of the specialized sets.
Passerby of Wandering Cloud: Niche / SP Support. Useful for SP-heavy openers. Its main value is generating a free starting Skill Point at the beginning of the battle.

Best Choice
Warrior Goddess of Sun and Thunder	2-Pc: Increases SPD by 6%. 4-Pc: When the wearer and their memosprite provide healing to ally targets aside from themselves, the wearer gains "Gentle Rain," which can be triggered up to 1 time per turn, lasting for 2 turn(s). While the wearer has "Gentle Rain," increases their SPD by 6% and all allies' CRIT DMG by 15%. This effect cannot be stacked.
Alternative Choice
Messenger Traversing Hackerspace	2-Pc: Increases SPD by 6%. 4-Pc: When the wearer uses their Ultimate on an ally, SPD for all allies increases by 12% for 1 turn(s). This effect cannot be stacked.

Passerby of Wandering Cloud	2-Pc: Increases Outgoing Healing by 10%. 4-Pc: At the beginning of the battle, immediately recovers 1 Skill Point.

2. Planar Ornaments

Broken Keel: Top Priority. The universal best-in-slot. Since you need Effect RES anyway to avoid stuns, this set gives the entire team free CRIT DMG.
Fleet of the Ageless: Best for DoT/ATK Teams. Use this if your DPS doesn't care about Crit (like Kafka). It provides HP for survival and a permanent ATK buff for the team.
Penacony, Land of the Dreams: Niche (Imaginary Teams). Only use this if running Dan Heng • IL or Dr. Ratio. It helps Luocha get his Ult back faster and boosts Imaginary DMG.

Best Choice
Broken Keel	2-Pc: Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
Alternative Choice

Luocha Team Compositions

Luocha is the ultimate plug-and-play support for SP-Hungry Hypercarries and Destruction units. Because he prints Skill Points and heals automatically, he’s the best friend for damage dealers who burn through resources or their own HP. He solves survival issues without ever stealing a turn (or a Skill Point) from your main DPS, making him the best-in-slot sustain for several top-tier archetypes:

SP-Hungry Hypercarries: Dan Heng • Imbibitor Lunae, Seele, Qingque.
HP Consumption Duos: Blade, Jingliu, Arlan.

Luocha Eidolons

Eidolon Performance

	Rating	Explanation
E1	★★★★★	The best stopping point. It transforms Luocha from a pure healer into a buffer by granting +20% ATK to all allies whenever his field is active. Since his field is up constantly, this is basically a permanent team-wide damage boost.
E2	★★★	A solid defensive upgrade that prevents one-shots. If he heals an ally with high HP, he grants them a Shield instead. It’s great for keeping squishy supports like Tingyun alive, but his base healing is usually enough on its own.
E4	★★	Honestly, the weakest of the bunch. It causes enemies to deal 12% less DMG while his field is active. It’s a nice debuff, but since Luocha already heals your team to full instantly, you rarely need the extra damage reduction.
E6	★★★★★	The whale’s delight. It adds a massive 20% All-Type RES Shred to his Ultimate. This is a rare and powerful damage multiplier that works for literally every DPS in the game, solidifying him as a premier offensive support.

Eidolon Effect

Eidolon

Effect

Ablution of the Quick

While the Field is active, ATK of all allies increases by 20%.

Bestowal From the Pure

When his Skill is triggered, if the target ally's HP is lower than 50%, Luocha's Outgoing Healing increases by 30%. If the target ally's HP is at 50% or higher, the ally receives a Shield that can absorb DMG equal to 18% of Luocha's ATK plus 240, lasting for 2 turns.

Surveyal by the Fool

Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.

Heavy Lies the Crown

When Luocha's Zone is active, enemies become Weakened and deal 12% less DMG.

Cicatrix 'Neath the Pain

Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.

Reunion With the Dust

When Ultimate is used, there is a 100% fixed chance to reduce all enemies' All-Type RES by 20% for 2 turn(s).

Conclusion

Luocha is hands down the best offensive healer, using his Abyss Flower field to grant your team infinite lifesteal while his Ultimate strips annoying enemy buffs. By aiming for 2,500+ ATK and high SPD, he acts as an infinite Skill Point printer and the perfect safety net for high-risk carries like Blade and Jingliu in endgame content—keeping your squad immortal without ever slowing down your offense.
