Suisui is a five-star Glacio Rectifier user who works as a healer and damage amplifier in Wuthering Waves. She keeps the team alive with HP-based healing, applies Glacio Chafe to enemies, and hands your carry a stack of powerful buffs through her Outro Skill. The trick with her build is that almost none of it revolves around damage stats. Her whole kit scales off healing and Energy Regen instead.
Quick answer: Give Suisui the Firstlight’s Herald rectifier, a five-piece Song of Feathered Trace echo set with Forbidden Bastion as her main echo, and push her to 260% Energy Regen while stacking HP and Healing Bonus. Slot her as the support in any Negative Status team.

Best weapons for Suisui
Suisui’s best weapon is her signature five-star rectifier, Firstlight’s Herald. It is built directly around her kit. The weapon raises her Max HP, restores Concerto Energy when she casts her Resonance Liberation, and grants nearby teammates the Kingfisher buff, which increases ally ATK and interacts with her healing and Glacio Chafe application.
If you do not pull her signature, there are solid fallbacks. Stellar Symphony is another five-star that boosts HP and grants a team ATK buff on healing Resonance Skill casts. On the free-to-play side, Variation and Call of the Abyss both provide the Energy Regen she needs to keep her rotation running.
| Weapon | Rarity | Why it works |
|---|---|---|
| Firstlight’s Herald | 5★ (limited) | Signature option, adds HP, Energy Regen, Concerto Energy, and a team ATK buff |
| Stellar Symphony | 5★ (limited) | HP boost plus a team ATK buff on healing skill casts |
| Variation | 4★ | Best budget pick, high Energy Regen and Concerto Energy on skill cast |
| Call of the Abyss | 4★ | Energy Regen and a Healing Bonus boost on Resonance Liberation |
Best echo sets, main echoes, and stats
Run a full five-piece Song of Feathered Trace set. Its two-piece bonus adds 10% Energy Regen, and its five-piece bonus triggers when Suisui inflicts Glacio Chafe, granting the whole team an ATK boost that scales with her Energy Regen, up to 25%. Since she applies Glacio Chafe throughout her rotation, she keeps this active with ease. If you do not have the set rolled yet, Rejuvenating Glow is a reliable alternative that leans on its Healing Bonus and team ATK buff.
For the main echo, Forbidden Bastion pairs best with the Song of Feathered Trace build because it hands the equipped character extra Healing Bonus on top of dealing Glacio damage. If you go the Rejuvenating Glow route instead, Fallacy of No Return is the match, and Bell-Borne Geochelone works as an early-game option.
| Echo slot (cost) | Main stat |
|---|---|
| 4-cost | Healing Bonus or HP% |
| 3-cost | Energy Regen or HP% |
| 3-cost | Energy Regen or HP% |
| 1-cost | HP% |
| 1-cost | HP% |
When tuning substats, prioritize Energy Regen first until you hit her breakpoint, then stack HP% and flat HP for stronger heals. Crit rate and Crit damage are low-value extras since her personal damage barely matters.
Reach 260% Energy Regen for full buffs
Energy Regen is the single most important number on Suisui. Her Resonance Liberation costs 175 Energy, so low Energy Regen breaks her rotation entirely. Her team buffs start scaling once she passes 200% Energy Regen and reach their ceiling at 260%.
| Effect | Scaling |
|---|---|
| Ally DMG dealt | +0.2% per 1% Energy Regen over 200%, up to 12% |
| Ally ATK | +0.12% per 1% Energy Regen over 200%, up to 50% |
Firstlight’s Herald makes this target far easier, since its extra 25% Energy Regen over Variation frees up a 3-cost echo slot for an HP% piece instead. On a four-star weapon you will lean more heavily on Energy Regen substat rolls to hit the mark.
Suisui skill priority
Her healing comes from her inherent skill, so you never need to level a skill just to improve sustain. Focus on the skills that drive her buffs and resource generation instead.
- Resonance skill
- Intro skill
- Resonance liberation
- Forte circuit
- Basic attack
Best teams for Suisui
Suisui works as a general healer, but she shines brightest with damage dealers who trigger Negative Status effects. Her Ceaseless Landscape field raises the max stack limits for statuses like Glacio Chafe, Havoc Bane, Spectro Frazzle, Fusion Burst, and Aero Erosion, so she can slot into most of these compositions and boost their output. Glacio carries such as Hiyuki and Lucilla benefit especially, since Suisui feeds them extra Glacio Chafe.
| Team | Members |
|---|---|
| Havoc Bane | Yangyang: Xuanling, Chisa, Suisui |
| Glacio Condensation | Hiyuki, Lucilla, Suisui |
| Fusion Burst | Aemeath, Denia, Suisui |
The Yangyang: Xuanling lineup is her strongest pairing. Xuanling stacks Havoc Bane fast, Chisa raises the Havoc Bane stack limit and shreds DEF, and Suisui’s field lets that Havoc damage ignore a chunk of enemy DEF and Havoc RES. The Hiyuki team is the premier Glacio option, and the Aemeath and Denia lineup covers Fusion Burst. If your existing team already runs a traditional healer like Shorekeeper or Verina, Suisui can step directly into that slot.

Once you have her Energy Regen at the right level and the Song of Feathered Trace set rolled with HP, Suisui becomes one of the most flexible supports on your roster. She keeps a team alive, applies Glacio Chafe on cue, and pushes your main carry into hyper-carry range without needing a single point of Crit.
