Stringmaster vs Lustrous Razor: 35.9% Crit BiS Guide

Stringmaster, that 5★ Rectifier, edges out Lustrous Razor (a 5★ Broadblade) for pretty much everyone thanks to its whopping 35.9% Crit Rate, plus those sweet ATK and DMG bonuses. It's straight-up BiS for Yinlin and Encore. Razor? It shines if you're running an ER-hungry Calcharo DPS setup. Heads up—these drop on V1.4 banners from Dec 12, 2024, to Jan 1, 2025 in Asia. We'll break down stats, best resonators, mats, and pull tips to smash ToA.

Stringmaster: The Full Scoop

Picture this: Stringmaster hits Lv.90 with 500 Base ATK, 35.9% Crit Rate baked in, Electric Amplification for a 12% DMG Bonus (stacks to 24% over 5s on Resonance Skill), and 12% ATK even off-field. It crushes Cosmic Ripples (which only gives 53.9% ATK%) because that ATK boost is unconditional—no strings attached. Post-2.0, it's top-tier Rectifier and BiS for Encore's RS DMG.

1. Slap it on Yinlin for that killer off-field Electro puppet.
2. Push to Lv.90 to max out Crit Rate.
3. Throw on some ER Echoes if she's starving.

Lustrous Razor: Your Complete Rundown

Lustrous Razor packs 587 Base ATK at Lv.90, 36.4% ATK%, and 12.8% Energy Regen. Its passive stacks +7% Resonance Liberation DMG (up to 21% at 3 stacks, lasts 12s after RS). Ascension perks? +25.6% ER and +16% Liberation DMG. Game8 calls it 7% per stack—perfect for Calcharo's rotations, speeding up that Concerto.

1. Stack all 3 RS before Liberation.
2. Lv.90 scales that ER beautifully.
3. Jinhsi loves it on Spectro Liberation.

Short bursts. Razor sustains where others falter.

Stats Face-Off

Stringmaster brings 35.9% Crit Rate for raw damage spikes; Lustrous Razor counters with 12.8% ER and 36.4% ATK% for endless sustain.

• Base ATK: 500 vs. 587.
• Substats: Crit Rate 35.9% vs. ATK% 36.4%.
• Passives: 12-24% DMG +12% ATK vs. 7-21% Liberation stacks.

1. Grab Stringmaster if your DPS lacks Crit.
2. Razor's your pick if Calcharo's ER dips under 150%.
3. Quick ToA test swaps decide it.

(Data dive: These edges come straight from in-game parses.)

Top Resonators and Synergies

Stringmaster rules Yinlin (off-field Electro puppet), Encore (BiS for RS), and flexes on Cantarella, Phoebe, Phrolova, or Zhezhi (Havoc/Spectro/Glacio). Lustrous Razor is Calcharo's signature, boosts Jinhsi or Jiyan (Spectro/Aero), and works Lumi or Lupa (Electro/Fusion). Yinlin thrives on that off-field ATK; Calcharo? ER for smoother rotations.

1. Yinlin or Encore: Stringmaster + ER Echoes.
2. Calcharo or Jinhsi: Razor + Liberation Sonatas.
3. Cycle Stringmaster off-field for 12% DMG everywhere.

Ever wonder why off-field matters so much? It keeps your teams humming.

Banner Drops and Timelines

Stringmaster's on the Absolute Pulsation limited in V1.4, Dec 12, 2024–Jan 1, 2025 Asia—160 Astrites per roll or Forging Tides. Razor's a permanent Convene guarantee. No Stringmaster rerun yet.

Mats and Upgrade Grind

Both weapons demand 34 cores/rings, 40 helices/residues, and 330k Shell Credits to Lv.90.

• Stringmaster: Crude Ring x6, Basic x6, Improved x10, Tailored x12; Lento Helix x6, Adagio x8, Andante x6, Presto x20.
• Razor: LF Whisperin x6, MF x6, HF x10, FF x12; Waveworn Residue 210 x6, 226 x8, 235 x6, 239 x20.

Grind smart—it's worth it.

Pull Value and Performance Edge

Stringmaster's universal Crit/ATK trumps Razor's ER/Liberation niche; Nov 20, 2025 tiers put Stringmaster ahead in ToA (my take: it's a clear winner based on parses). BiS for Encore/Yinlin, laps 4★s; Razor's B-Tier on Calcharo. Pull Stringmaster even without Yinlin—it's that versatile.

1. High-value Stringmaster pull.
2. Skip Razor unless Calcharo's your main.
3. F2P? Free Razor guarantee, but chase Stringmaster.

Long-Haul Viability Post-2.0

Stringmaster boosts any DPS universally, outshines standards except pure ATK sticks; Razor unlocks Calcharo/Jinhsi clears. No nerfs incoming.

1. Swap to Stringmaster for endgame.
2. Hoard Crit sands for it.
3. Patch notes will flag new farms.

Solid future-proofing.
