Remembrance Trailblazer Best Build: Best Relics, Light Cones, and Team Comps | Honkai: Star Rail 3.8

Looking for the best Trailblazer (Remembrance) build guide in Honkai: Star Rail 3.8? You’re in the right place. This page breaks down RMC’s trace priority, key materials, Light Cone picks, relic + planar options, and real endgame team comps—so you can build them cleanly without wasting weeks on “almost works” setups.

Remembrance Trailblazer Overview

Remembrance Trailblazer is a tempo-support who fights by summoning a memosprite, Mem, then turning your carry into a “more turns + more damage instances” machine. Your Skill brings Mem out (or heals Mem and adds Charge if Mem is already present), while your Ultimate also re-summons Mem, gives a big chunk of Charge, and drops an AoE hit. Mem starts fast (SPD 130) and builds Charge from the team’s total Energy regeneration, so the more your squad cycles Energy, the faster Mem reaches 100% and immediately takes a key turn. 

Once Mem is ready, it can advance one ally by 100% and apply “Mem’s Support” for 3 turns—then every damage instance that ally deals triggers extra True DMG based on the original hit, which is why multi-hit carries feel disgusting with this kit. Mem also boosts the whole team’s CRIT DMG, and RMC’s Technique can Time-Stop enemies pre-fight to buy setup time. In practice, RMC shines in endgame burst checks (MoC/Shadow), turn-race farming, and any comp built around high-hit-count DPS, follow-ups, or Energy-hungry ultimates.

 

Remembrance Trailblazer Key mechanics & features

• Energy economy → Mem’s Charge clock: RMC converts teamwide Energy regeneration into Mem uptime—Mem gains 1% Charge per 10 total Energy regenerated. Mem starts at 130 SPD, acts immediately at 100% Charge, and otherwise auto-attacks, so faster rotations and batteries directly mean more Mem turns.
• Turn-control burst → “Mem’s Support”: Once Mem is fully Charged, it can 100% Action Advance one chosen ally and grant “Mem’s Support” for 3 turns. Every damage instance that ally deals triggers extra True DMG based on the original hit—multi-hit and follow-up carries love this.
• Ultimate-cost scaling → pick the right carry: RMC’s True DMG gets stronger when you support high Max Energy units. A key Bonus Ability boosts the True DMG multiplier by 2% per 10 Energy above 100, up to +20% at 200—so 140–200-cost ult DPS cash out hardest.
• Crit-DMG sharing + clean opener: Mem grants teamwide CRIT DMG based on Mem’s CRIT DMG plus a flat bonus, so RMC stacks CRIT DMG. RMC also gets an early first turn, a big first-summon Charge boost, and a pre-fight Time-Stop—just note many buffs won’t transfer to memosprites unless targeted.

 

Remembrance Trailblazer Trace Priority

Memosprite Talent	⭐⭐⭐⭐⭐ (Top)	Highest ROI because it directly scales Mem’s baseline value (survivability + overall contribution) across every turn it takes.
Memosprite Skill	⭐⭐⭐⭐⭐ (Top)	This is the payoff button—your strongest team impact comes from Mem’s support window, so leveling it boosts what you feel most.
Ultimate	⭐⭐⭐⭐⭐ (Top)	Your main tempo reset—re-summons Mem, grants a large Charge chunk, and smooths cycles when Charge desyncs in hard fights.
Talent	⭐⭐⭐⭐ (High)	Buffs everything Mem does—HP scaling, Charge-from-Energy conversion, and CRIT DMG sharing—so every upgrade multiplies team output dramatically over time.
Skill	⭐⭐⭐ (Medium)	Reliable maintenance tool—summon Mem early, then heal it and add Charge later, keeping support uptime SP-efficient each rotation loop.
Basic ATK	⭐⭐ (Low)	Lowest priority; mostly for SP recovery and relic uptime, since it barely affects Mem’s Support engine at all.

 

Remembrance Trailblazer Key Materials

To fully build RMC, you’ll need a clean set of key materials for three things: character ascension, Trace upgrades, and the final high-tier unlocks that gate the last stretch of progression. Farming these early keeps your upgrade path smooth, so you can level important nodes on schedule instead of getting stalled by one missing drop.

Auspice Sliver x 12	Tracks of Destiny x 5	Conqueror's Will x 65

We also offer a complete breakdown of every material he needs, helping you plan efficient farming routes and prioritize essential resources for her full optimization.

 

Remembrance Trailblazer Lightcones

Best Lightcones

Victory In a Blink

Increases the wearer's CRIT DMG by 12%. When the wearer's memosprite uses an ability on an ally target, increases the DMG dealt by all ally targets by 8%, lasting for 3 turn(s).

Victory in a Blink is tailor-made for RMC because it double-dips on what RMC already wants to do. The flat CRIT DMG boost directly amps RMC’s scaling and the CRIT DMG they pass around through Mem. More importantly, Mem frequently uses an ally-targeted ability, so you can keep the cone’s teamwide DMG buff rolling with near-perfect uptime—no awkward triggers, just clean, universal value.

 

Alternative Lightcone

Long May Rainbows Adorn the Sky	The premium speed-and-pressure pick: 18% SPD makes RMC smoother, it turns a tiny 1% HP tax into a huge extra memosprite hit, and Mem’s support action adds a short 18% “take more DMG” window. Bring healing.
Sweat Now, Cry Less	The clean “no-setup” option: 12% CRIT Rate helps your build feel less scuffed, and as long as Mem is on the field, both RMC and Mem get a flat 24% DMG boost—easy, consistent chip damage.
Geniuses’ Greetings	A solid budget fallback if you play RMC SP-positive: ATK% is always active, and after you Ultimate (which you’re using for uptime anyway), your Basic ATKs—and Mem’s—gain 20% Basic DMG for 3 turns. Best when you basic often.

 

Remembrance Trailblazer Best Relic, Ornaments

As Support
Hero of Triumphant Song	2-Pc: Increases ATK by 12%. 4-Pc: While the wearer's memosprite is on the field, increases the wearer's SPD by 6%. When the wearer's memosprite attacks, increases the wearer's and memosprite's CRIT DMG by 30%, lasting for 2 turn(s).
Lushaka, the Sunken Seas	2-Pc: Increases the wearer's Energy Regeneration Rate by 5%. If the wearer is not the first character in the team lineup, then increase the ATK of the first character in the team lineup by 12%.
RMC always has a memosprite on the field, so Triumphant Song’s SPD boost and the 30% CRIT DMG buff stay very consistent, making your rotations smoother. Lushaka adds 5% ERR for faster Ult cycles, and the 12% ATK buff goes straight to your main carry.

 

As Sub-DPS
Hero of Triumphant Song	2-Pc: Increases ATK by 12%. 4-Pc: While the wearer's memosprite is on the field, increases the wearer's SPD by 6%. When the wearer's memosprite attacks, increases the wearer's and memosprite's CRIT DMG by 30%, lasting for 2 turn(s).
The Wondrous BananAmusement Park	2-Pc: Increases the wearer's CRIT DMG by 16%. When a target summoned by the wearer is on the field, CRIT DMG additionally increases by 32%.
With Mem permanently counting as your summoned target, BananAmusement Park gives RMC a huge CRIT DMG package, which also improves any CRIT DMG-based scaling RMC contributes. Triumphant Song then layers more SPD and a frequent CRIT DMG buff for both RMC and Mem, boosting overall damage presence while supporting.

 

Remembrance Trailblazer Relic & Ornaments Best Stats

Main Stats	Body: Crit Damage Feet: SPD Planar Sphere: Ice Damage Bonus Link Rope: Energy Regen
Sub Stats	Crit Damage > Attack > SPD

 

Remembrance Trailblazer Best Teams

Argenti + RMC + Sunday + Huohuo

DPS	Sub-DPS	Support	Support
Argenti	RMC	Sunday	Huohuo

This is the cleanest “make one carry go nuclear” RMC setup: Argenti’s big Ultimate cost is exactly the kind of DPS Mem loves to turbo, while Sunday + Huohuo keep the whole engine fueled so you don’t get stuck waiting on energy/charge. Best for MoC-style boss rooms and elite waves where consistent Ult cycles = consistent clears.

 

The Herta + Anaxa + RMC + Lingsha

DPS	Sub-DPS	Support	Support
The Herta	Anaxa	RMC	Lingsha

This is the “everything is AoE and it never stops” team. The Herta benefits hard from RMC’s tempo tools, and pairing her with Anaxa gives you better wave coverage + more damage per rotation (PF especially). Lingsha is a common sustain choice here because she fits the fast, multi-wave rhythm and supports frequent cycling.

 

Castorice + RMC + Cyrene + Hyacine

DPS	Sub-DPS	Support	Support
Castorice	RMC	Cyrene	Hyacine

If you’re building around Castorice, RMC is one of the most-used “second support” slots—especially when you’re not running the absolute premium Evernight/Cyrene package. Hyacine stabilizes the HP-drain pace, Tribbie brings universal team amplification, and RMC keeps your turns/damage rhythm smooth across longer fights. This setup shows up in team writeups and real clears.

 

Conclusion

Once your relics are stable and your traces are online, RMC becomes one of those characters you stop “thinking about” mid-fight—because the team just flows. Use the recommended comps as your baseline, then tune the flex slot based on what the stage demands (boss pressure vs. wave clear).

And if you’re one key piece short—maybe that missing character to complete the shell, or you want to secure a Light Cone upgrade before the next reset—LDShop is a quick, safe way to top up Oneiric Shard and finish the build without turning it into a week-long payment quest.
