Suisui Build Guide 2026: Best Weapons, Echoes & Teams
This is the launch-week Suisui build guide for Wuthering Waves 3.5 Phase 2. Suisui — the older sister of Yangyang Xuanling, from a prestigious Mingting family — is a 5★ Glacio Rectifier Support/Healer debuting in the Phase 2 banner (July 31, 2026). She is the new universal sustain slot for the Effect system: her kit revolves around a high Energy Regen breakpoint (260%) that unlocks her full buffing potential, and her Outro Skill grants the team a sizable ATK buff that scales with her own Energy Regen.
If you play an Effect team (Yangyang Xuanling or Feixue), Suisui is the best-in-slot sustain. Even at 0+0 she unlocks all core buffs and healing — no constellations required.
Weapon: Sipping Dew (signature) > Stellar Symphony > Variation (4★ F2P)
Echo set: Wishes of Dustfall 5-piece (3.5 new Glacio support set)
Target stats: 260% Energy Regen (hard breakpoint) > HP% > Healing Bonus
Teams: Yangyang Xuanling + Qianxiao + Suisui · Feixue + Rosella + Suisui
Why Suisui? Role & Strengths
Suisui fills the universal sustain + ATK buffer role in the Effect meta. Her kit has three defining features:
- 260% Energy Regen breakpoint — For every 1% of Energy Regen Suisui has, the team gains +0.1% ATK, up to +25% team ATK at 260% ER. This is the single most important build target.
- Effect-layering field — Her Liberation creates a field that adds 3 extra Effect stacks whenever teammates apply or deal Effect damage. This massively accelerates Effect-team ramp.
- Low-investment ceiling — All core buffs and healing are unlocked at 0+0. Constellations add power but are not required to make her viable.
Her weaknesses: low personal damage (she's a pure support), and she only truly shines in Effect teams — outside of Effect comps, generic healers like Shorekeeper or Verina may offer similar or better utility.

|---|---|
| Rarity | 5★ |
| Element | Glacio |

Best Weapons for Suisui
Suisuni's weapon priority is driven by one thing: Energy Regen. The 260% breakpoint is non-negotiable — if you can't hit it, you lose up to 25% team ATK. Weapons that give ER in their sub-stat or passive are therefore valued far above raw-ATK weapons.
| Tier | Weapon | Rarity | Notes |
|---|---|---|---|
| S | Sipping Dew | 5★ Signature | 77% Energy Regen sub-stat. Passive: casting Liberation refunds Concerto energy and grants the team an ATK buff. With Sipping Dew, hitting 260% ER is trivial — a single 3-cost echo with ER main stat covers the gap. Best-in-slot. |
| S | Stellar Symphony | 5★ (Shorekeeper sig) | Shorekeeper's signature weapon also has ER sub-stat and a team-buff passive. Nearly as good as Sipping Dew for Suisuni's purposes — slightly less ATK buff, but similar ER coverage. |
| A | Variation | 4★ Standard | Best F2P option at S5. 51.8% Energy Regen + 8 Concerto on swap. The ER sub-stat makes it easy to reach 260% with echo investment. Gaps from 5★ weapons are mainly in team-ATK buff magnitude, not ER. |
| B | Abyssal Echo | 4★ Forgeable | Free forgeable Rectifier with ER sub-stat. Solid transition weapon if you don't have Variation — fully F2P-friendly. |
| C | Resonance Caller | 4★ | ER sub-stat but weaker passive. Emergency fallback only. |

Best Echo Set for Suisui — Wishes of Dustfall (5-piece)
Suisuni's best-in-slot set is Wishes of Dustfall, the new Glacio support Sonata introduced in 3.5:
- 2-piece bonus: +10% Energy Regen
- 5-piece bonus: When the wearer triggers or contributes to Effect stacks, the team's main DPS gains a scaling ATK buff — perfectly aligned with Suisuni's role as an Effect-team sustain.
The 4-cost echo should be Thousandfold Crimson Tower (千傀重楼), which provides additional Effect-related utility. For the 3-cost slots, prioritize Energy Regen main stats until you hit the 260% breakpoint; once you're over 260%, you can swap one 3-cost to HP%.
Main Stat Priority by Cost
| Cost Slot | Main Stat | Notes |
|---|---|---|
| 4-cost | Healing Bonus or HP% | Healing Bonus if you need more healing; HP% if your healing is already sufficient. Pick whichever has better sub-stats. |
| 3-cost ×2 | Energy Regen | Both 3-cost slots should have ER if you're below 260% total. If using Sipping Dew or Stellar Symphony, one ER main stat is usually enough — swap the second to HP%. |
| 1-cost ×2 | HP% | Standard for sustain characters. |
Sub-stat Priority
- Energy Regen — top priority until you hit 260%
- HP% — improves survivability and healing
- Flat HP — minor bonus
- Healing Bonus — only if already at 260% ER
ATK sub-stats are useless on Suisuni — her personal damage is negligible. Don't waste tuning resources on ATK rolls.
Skill Upgrade Priority
Suisuni's healing and buffing come from her Resonance Liberation and Resonance Skill — these are the top priority. Basic Attack can stay at level 6.
| Priority | Skill | Reason |
|---|---|---|
| 1 | Resonance Liberation | Main source of healing and the Effect-layering field. Max first. |
| 2 | Resonance Skill | Secondary healing and buff application. |
| 3 | Outro Skill | Team ATK buff — scales with ER, worth leveling. |
| 4 | Resonance Circuit | Utility passive; level when convenient. |
| 5 | Basic Attack | Leave at level 6. Suisuni should rarely be on-field auto-attacking. |
Best Team Comps for Suisui
Suisuni is designed for Effect teams — comps that rely on stacking Effect stacks (Glacio Chafe, Void, Spectro, etc.) to trigger burst windows. She has two top-tier teams in 3.5:
1. Yangyang Xuanling + Qianxiao + Suisui (Yang-Qian-Sui)
| Role | Character | Function | Notes |
|---|---|---|---|
| Main DPS | Yangyang Xuanling | Havoc Effect DPS, heavy-hit burst | Relies on Effect stacks for burst windows |
| Sub-DPS | Qianxiao | Void applier, DEF shred, anti-res | Backline stacks 6 Void layers, lowers enemy DEF |
| Sustain | Suisui | Healing, Effect layering, team ATK buff | +25% team ATK at 260% ER |
Rotation: Qianxiao backline → swap to Suisuni, cast Liberation (deploys Effect field) → swap to Yangyang Xuanling for heavy-hit burst. Suisuni's field adds 3 extra Effect stacks on every application, massively accelerating Yangyang's burst window.
Substitute: If you don't have Qianxiao, Mortefi or Yunno can fill the second slot as heavy-hit buffers.
2. Feixue + Rosella + Suisui (Fei-Luo-Sui)
| Role | Character | Function | Notes |
|---|---|---|---|
| Main DPS | Feixue | Glacio Chafe burst DPS | Cashes in Glacio Chafe stacks for burst |
| Sub-DPS | Rosella | Glacio Chafe applier, on-field driver | Stacks Chafe while Suisuni sustains |
| Sustain | Suisui | Healing, Effect layering, team ATK buff | Also a Glacio unit — benefits from Glacio resonance |
Rotation: Rosella on-field stacking Glacio Chafe → swap to Suisuni, cast Liberation + Skill (heals + Effect field) → swap to Feixue for burst. The cycle is roughly 25 seconds and can hit 100k+ DPS.
Constellation Guide
Suisuni's 0+0 is fully functional — all core buffs, healing, and the Effect field are unlocked at base. Constellations add power but are not required.
| Sequence | Effect | Priority |
|---|---|---|
| S1 | Extends buff duration, grants Super Armor (interrupt resistance), and lifts ATK buff cap. Key constellation — biggest team DPS gain. | Top priority |
| S2 | Grants teammates +50% Crit Damage. Massive DPS spike for the main carry. | High |
| S3 | Shortens Suisuni's field time — faster rotation, more DPS uptime for the main carry. | Medium |
| S4 | +50% personal healing. Useful for high-damage content but doesn't boost team DPS. | Low |
| S5 | +100% Basic Attack / Heavy Attack damage. Negligible — Suisuni shouldn't be auto-attacking. | Low |
| S6 | +500% Crit Damage on Outro and Resonance Skill. Niche, mainly for whale showcases. | Low |
Pull priority: S1 > S2 > S3 > signature weapon. If you're choosing between constellations and the weapon, S1-S3 are higher value than Sipping Dew. The weapon is a quality-of-life upgrade (easier ER breakpoint), not a power spike.
Suisuni Target Stats (Endgame Build)
| Stat | Target | Notes |
|---|---|---|
| Energy Regen | 260% | Hard breakpoint. Below this, you lose team ATK buff. |
| HP | 40,000+ | Ensures survivability and sufficient healing. |
| Healing Bonus | Optional | Only if ER and HP are already capped. |
| ATK | Irrelevant | Don't build ATK — her personal damage is negligible. |
Is Suisui Worth Pulling?
Yes, if you play an Effect team. Suisuni is the best sustain for both Yangyang Xuanling and Feixue comps, and she's the universal Effect-team healer going forward. At 0+0 she's already complete — no need for constellations or the signature weapon unless you're a whale.
Skip if: You don't play Effect teams and don't plan to. Verina and Shorekeeper remain perfectly fine general healers for non-Effect comps. Also consider skipping if you're saving for future characters (Qingxiao, Jingran, Xinyuehu, Suoming are all upcoming in late 3.5 / 3.6).

FAQ
Is Suisuni a must-pull?
If you play Yangyang Xuanling or Feixue teams, yes — she's their best-in-slot sustain. For general use, she's good but not required; Verina and Shorekeeper can still cover most teams.
Can Suisuni replace Shorekeeper?
Only in Effect teams. Shorekeeper remains the better general healer for non-Effect comps because her buffs don't depend on Effect stacks.
Does Suisuni need her signature weapon?
No. Variation S5 is a perfectly viable F2P option — you just need to invest more ER in echoes to hit the 260% breakpoint. Sipping Dew makes the build easier but doesn't unlock new functionality.
What is the 260% Energy Regen breakpoint?
Suisuni's passive grants the team +0.1% ATK for every 1% of her Energy Regen, up to +25% at 260% ER. Below 260%, you're leaving team ATK on the table. This is the single most important build target.
