Wuthering Waves 3.7 to 4.0 Pull Guide: Should You Pull Hsin, Suoming, or Save for Lily and New Federation?

With Kuro Games officially wrapping up the Version 3.7 Special Broadcast - "Falling Sanctum, Waking Moon" - slated for release on September 30, 2026, Wuthering Waves players find themselves at the most critical financial crossroad since the game's launch.

On one hand, Version 3.7 serves as the climactic finale to the grand Mengzhou storyline, delivering two back-to-back 5-star Electro heavyweights: the dual-form Sentinel DPS Hsin and the explosive fast-swap sub-DPS Suoming. On the other hand, early credible leaks and test-server traces for Version 3.8 have introduced Lily - a Gothic Lolita perfumer from the enigmatic Domain of Heart leaked as the dedicated "Unison Healer" - alongside the return of second-generation Joint Wish banners. Looming right over the horizon is the monumental Version 4.0 expansion, which will transition Rovers to the high-tech New Federation (Amber City / Syngelem), featuring pilotable mechas and Fusion Rover awakening.

If your Astrite reserves were already drained by Qingxiao or Jingran in 3.6, choosing where to deploy your Radiant Tides over the next three months will make or break your account's endgame progression. This guide cuts through the hype, comparing kit value, team-building costs, future synergies, and distinct account archetypes to give you an actionable roadmap from 3.7 all the way to 4.0.

Quick Master Roadmap (3.7 - 3.8 - 4.0)

Version 3.7 Deep Dive: The Dual Electro Temptation

1. Hsin: The Sentinel Hypercarry

· Rarity & Element: 5-Star Electro

· Weapon: Rectifier (Signature: Blooming Jadehaven)

· Role: Stance-Switching Main DPS / Burst Aerial Hypercarry

· Echo Set: 5-Piece Heart of Sworn Vigil

Strengths & Kit Highlights

Hsin is not just another Electro damage dealer; she is the lore-defining centerpiece of Mengzhou's conclusion. Operating through two distinct combat stances - Answering Form and Illumining Form - she weaves ground combos directly into soaring aerial strikes.

Her gameplay introduces the Unison and Electro Flare systems. When Unison is triggered through coordinated party actions, Hsin unlocks devastating resonance discharges with multi-layered multipliers. Her damage distribution is heavily concentrated in Resonance Skill and Resonance Liberation damage, allowing her to vaporize high-difficulty Tower of Adversity floors in compact damage windows.

The Hidden Costs & Caveats

· High Rotation Rigidity: Hsin is not a "mash basic attack" character. Failing to properly execute her dual-form cancel loops cuts her personal damage ceiling by upwards of 30%.

· Severe Energy Demands: Without her signature weapon Blooming Jadehaven or high Energy Regeneration sub-stats, her Liberation uptime stumbles, creating painful dead time in rotations.

· Team Dependency: While functional with standard buffers, Hsin's theoretical ceiling is mathematically tied to teammates who generate Unison stacks quickly.

2. Suoming: The Fast-Swap Catalyst

· Rarity & Element: 5-Star Electro

· Weapon: Sword (Signature: Unspoken Rue)

· Role: Offensive Sub-DPS / Unison Accelerator / Tactical Quick-Swap

· Echo Set: 5-Piece Heart of Sworn Vigil

Strengths & Kit Highlights

Scheduled for the second half of 3.7, Suoming solves the exact pacing puzzle that Hsin presents. Armed with a swift blade and elusive mobility, Suoming can either burn her own accumulated Unison stacks to unleash rapid on-field burst damage or exit early via Outro Skill to grant substantial Electro Deepen and Resonance Skill amplification to the incoming character.

For players aiming to build the premier Unison Electro Dual-Core team, Suoming acts as both the engine and the sub-battery. Her quick swap animations also make her forgiving to pilot against aggressive bosses in the Tactical Hologram challenges.

Caveats for Low Spenders

If you do not plan to pull Hsin, Suoming's standalone pull value drops significantly. While she can operate as an independent quick-swap driver, her multipliers outside Unison setups do not vastly outshine well-invested existing sub-DPS options like Yinlin, Sanhua, or Changli.

Version 3.8 Leaks: The Gothic Enigma "Lily" & Joint Reruns

Just as players prepare their wallets for Version 3.7, insider information from beta clients and reliable community leakers has shifted the spotlight toward Version 3.8 (expected around November 11, 2026).

1. Who is Lily?

Lily has taken social channels by storm due to her drastic aesthetic departure from Mengzhou's traditional Wuxia and Xianxia themes. Featuring pink twin-tails, dark Gothic Lolita garments, white thigh-highs, and perfumer paraphernalia, she represents the "Domain of Heart" - a liminal world space bridging the gap between Mengzhou and the overseas Westernized territories.

Leaked Role: The "Unison Healer"

The most critical revelation surrounding Lily is her combat archetype:

1. 1. Dedicated Unison Support & Sustain: Early data indicates Lily generates party-wide Unison resonance through periodic perfume mist fields, bypassing the tight energy requirements that Hsin and Suoming struggle with at base investment.

2. 2. Resonance Liberation Buffing: Unlike existing defensive healers who primarily amplify Basic or Heavy attack damage, Lily's kit directly augments team Resonance Liberation damage and elemental shred.

3. 3. New 4-Cost Boss Echo: Leaks confirm 3.8 will debut a brand-new world boss Echo explicitly tailored for Unison sustain sets, signaling a complete meta cycle.

Strategic Takeaway: Pulling Hsin in 3.7 without securing Lily in 3.8 may leave your Unison team feeling like an "incomplete puzzle." If you are tight on pulls, pulling the core buffer/healer (Lily) often yields longer account shelf-life than pulling both pure damage dealers in 3.7.

2. 3.8 Reruns and the Second Chronicled Wish

Version 3.8 is anticipated as a transitional bridge before 4.0. Consequently, Kuro Games is reportedly preparing high-value rerun combinations:

· Xuanling (Yangyang SP): Highly requested rerun for Aero hypercarry enthusiasts.

· Sisi: Absent from banners since Version 3.2, making her a prime rerun candidate.

· Second Joint Wish Banner: Rumors point toward a second curated multi-character banner, allowing players to target legacy 1.X and early 2.X resonators and standard 5-star signature weapons with guaranteed pity carryover.

· Cosmetic Drops: Leaks also highlight a premium visual FX skin for Feixue and an event outfit for Suisui.

The 4.0 Horizon: The New Federation Mega-Expansion

Why should any player consider skipping both 3.7 and 3.8 altogether? The answer lies in Version 4.0.

Historically in gacha gaming, transitional patches at the tail end of an era (e.g., 1.8, 2.8, 3.8) are engineered to exhaust player currencies before a revolutionary expansion resets the benchmark.

What 4.0 Brings to Wuthering Waves:

4. 1. The New Federation (Amber City / Syngelem): A drastic jump from ancient martial arts bastions to sleek, vertical sci-fi metropolises with neon-lit skylines, rail transit, and advanced robotics.

5. 2. Fusion Rover Awakening: Rover will unlock their Fusion form, complete with bespoke weapon arts, cinematic resonance bursts, and team utility that rivals limited 5-stars.

6. 3. Mecha Piloting & Mounted Combat: Early leaks suggest large-scale combat encounters allowing players to board and operate tactical mechanized suits in the open world.

7. 4. Next-Generation Power Ceiling: Every x.0 launch introduces characters designed around fresh regional mechanics that redefine the endgame meta for the subsequent year.

If you spend every Astrite on 3.7 and 3.8, you will enter 4.0 with empty pockets right when the most innovative units arrive.

Player Profile Decision Matrix: Which Path Should You Choose?

Archetype A: The Strict F2P & Lunite Subscription Player

· Rule: Do NOT pull both Hsin and Suoming unless you win an early 50/50.

· Recommendation: If you lack an elite limited on-field hypercarry, pull Hsin at E0. Pair her with free-to-play enablers like Sanhua or the free selector units provided during the 3.7 Moonchase festivities. Ignore Suoming, and preserve your remaining 70-80 pulls to secure Lily in 3.8.

· Alternative: If your current roster already clears Tower of Adversity Hazard Zone with 30/30 stars, skip 3.7 entirely. The free rewards in 3.7 will boost your hoard to over 150+ pulls by the time 4.0 arrives.

Archetype B: The Meta-Driven Endgame Optimizer

· Recommendation: The Unison archetype is designed as an interlocking engine. The optimal investment route is Hsin (E0R1) -> Skip Suoming (substitute with Yinlin or Jianxin) -> Lily (E0) in 3.8. Hsin's signature weapon (Blooming Jadehaven) provides roughly a 22% damage uplift over alternative 5-star rectifiers, making her weapon higher priority than Suoming's base copy.

Archetype C: The Aesthetic & Lore Player

· If you adore traditional Chinese wuxia elegance, dragon motifs, and Sentinel majesty: Hsin is an unmissable emotional climax to the Mengzhou storyline.

· If you prefer Western dark fantasy, Gothic Lolita dresses, and twin-tail anime designs: Skip 3.7 and go all-in on Lily in 3.8.

Projected Astrite Income (Version 3.7 through 3.8)

Knowing how many pulls you will earn allows you to calculate exact pity thresholds before pulling the trigger:

Note: With 3.7 offering two free 5-star selectors from legacy rosters and generous anniversary-tier festival checks, your account will gain considerable horizontal depth even without touching the limited banner.

Final Pull Priority Tier List

To summarize every upcoming option on a clear, comparative scale:

8. 1. Tier S+ (Meta Pillar / Irreplaceable):

· Lily (3.8 Leaked) - If confirmed as the premier Unison healer/battery, supports of this archetype retain value across multiple version cycles.

· Hsin (3.7 Phase 1) - Absolute pinnacle of Electro on-field damage; top tier aerial fluid combat.

9. 2. Tier S (High Value Synergy):

· Hsin's Signature Weapon (Blooming Jadehaven) - Massive stat stick that drastically stabilizes her Liberation rotation.

· Suoming (3.7 Phase 2) - Best-in-slot partner for Hsin; fluid, high-burst sub-DPS.

10. 3. Tier A (Conditional / Targeted Reruns):

· Xuanling / Yangyang SP (3.8 Rerun Pool) - Essential for dedicated Aero teams.

· Sisi (3.8 Rerun Pool) - High-utility staple for accounts lacking Havoc/Glacio supports.

11. 4. Tier B / Skip (Safe to Pass):

· Phase 1 Reruns (Iuno, Chisa) - Good characters, but outclassed by current 3.X offensive ceilings.

· Random Chronicled Wish Spends - Never pull on mixed banners unless you have enough currency to guarantee your chosen path.

Summary Checklist for Launch Day

· ☐  Redeem any lingering 3.7 livestream codes before the server update.

· ☐  Claim your two free 5-star selectors during the Moonchase Festival before finalizing any pulls.

· ☐  Test Hsin extensively in the trial arena on September 30. Ensure her stance-dancing and aerial cancels match your preferred playstyle.

· ☐  Check 3.8 beta leaks during the second week of 3.7: Official drip marketing and detailed beta skill leaks for Lily will surface before Hsin's banner ends, giving you exact numerical clarity.

· ☐  Never build pity on Suoming's banner if your heart is set on the Gothic perfumer Lily or the mecha battlefields of 4.0!
