WuWa Suisui Weapon Guide: Firstlight’s Herald and Best Alternatives

Wuthering Waves Version 3.5, titled“Blade of Past Resounds, Lingering Dream Hymns,”is set to launch on July 10, 2026, bringing with it a wealth of new content and a roster of fresh Resonators. Among the most anticipated additions is Suisui, a 5-star Glacio Rectifier who serves as a healer and support unit.

For players planning to invest in Suisui, understanding her weapon options is critical. This guide breaks down everything you need to know about Firstlight’s Herald (her signature 5-star Rectifier), its stats, passive effects and the best alternative weapons to consider. 

Suisui Overview: Why Weapon Choice Matters

Before diving into the weapons themselves, it’s essential to understand what Suisui does—because her weapon choices are directly tied to her kit’s demands.

Suisui’s kit revolves around HP-scaling healing and team-wide damage amplification. Her Resonance Liberation deploys a domain called Ceaseless Landscape, which raises the maximum stack limits of elemental debuffs (including Glacio Chafe, Havoc Bane, Spectro Frazzle, and others) while also enabling Havoc DMG to ignore enemy DEF and RES.

Her Outro Skill grants up to 25% All DMG Amplification to the incoming Resonator—one of the longest-lasting universal buffs in the game. This buff scales with her Energy Regen, meaning the more ER you stack, the stronger her team contribution becomes.

Critical Stat Requirements

Suisui has a very high Energy Regen requirement—260% is the target for optimal performance. Below 200%, her buffs fall off significantly. This single stat dictates almost every build decision, starting with her weapon.

Firstlight’s Herald: The Signature Weapon

Firstlight’s Herald is the 5-star Rectifier signature weapon for Suisui. It will be available through the Absolute Pulsation weapon banner during Phase 2 of Version 3.5, running alongside Suisui’s character banner.

Stats (Level 90, Syntonization Rank 1)

Passive Effects (R1)

Firstlight’s Herald has a layered passive that directly complements Suisui’s support kit:

• Max HP +12%– Strengthens her HP-scaling healing.
• Resonance Liberation restores 8 Concerto Energy– Accelerates her rotation (triggered once every 20s).
• Kingfisher buff– Casting Intro Skill or Resonance Skill grants nearby party members Kingfisher for 30s:
  • If Suisui is on-field: Party members with Kingfisher gain +20% ATK.
  • If Suisui is off-field: Inflicting Glacio Chafe grants Tinted Snow(6s), and healing grants Ripples(6s). Having both simultaneously enhances Kingfisher’s effect.
• Outro Skill synergy– If Suisui heals and inflicts Glacio Chafe while on-field, she gains both Tinted Snow and Ripples for 6s upon casting Outro Skill.

In simpler terms: Firstlight’s Herald provides massive Energy Regen, restores Concerto Energy, boosts Max HP, and delivers a team-wide ATK buff—making it the perfect fit for Suisui’s support-oriented playstyle.

Why It’s Her Best-in-Slot

The 77% Energy Regen substat alone is transformative. It allows Suisui to reach her 260% ER target with far fewer substat rolls, freeing up Echo slots for HP% and Healing Bonus. The Concerto Energy restoration speeds up her rotations, and the ATK buff adds real offensive value to any team.

Verdict: If resources permit, Firstlight’s Herald is highly recommended—it’s the single most impactful investment you can make for Suisui.

Alternative Weapons for Suisui

If you don’t plan to pull for Firstlight’s Herald, several other Rectifiers can serve as strong alternatives. The key is Energy Regen—any weapon that provides ER as a secondary stat will outperform raw ATK options.

Stellar Symphony (5-Star)

Stellar Symphony is Shorekeeper’s signature weapon. It shares the same high ER substat as Firstlight’s Herald, making it an excellent alternative. The passive increases HP and restores Concerto Energy, which aligns well with Suisui’s needs.

Verdict: If you already own Stellar Symphony from a previous banner, it’s a fantastic substitute. However, pulling it specifically for Suisui is less recommended than going for Firstlight’s Herald, as the latter’s Kingfisher buff provides superior team value.

Variation (4-Star)

Variation is the bestfree-to-playoption for Suisui. The 51.8% ER helps her reach her stat targets, though you’ll need more substat investment compared to the 5-star options. It’s a solid budget choice that performs adequately in most content.

Call of the Abyss (4-Star)

Call of the Abyss offers the same ER substat as Variation. Choose whichever you have better refinements on, or the one that fits your team’s specific needs.
