Banner Schedule & What You're Getting Into

Version 3.7 goes live November 5, 2025 (UTC+8) and runs through December 16 — that's a solid six weeks to figure out your pulling strategy. Phase 1 (November 5–26) showcases Cyrene's debut alongside Hyacine, plus reruns for Castorice and Tribbie. Phase 2 (November 26–December 16) switches things up with Phainon, Cipher, and Mydei reruns, though Cyrene sticks around for both phases.

The 4-star lineup's actually decent this time. Moze brings Hunt synergies, Lynx covers your budget sustain needs, and Pela's 38% All-Type RES reduction makes her a solid pick for Saber teams. Oh, and those Saber banners from the Fate collab? Yeah, they're still running since July 11, 2025.

Cyrene: Support Disguised as DPS Chaos

Here's where things get interesting. Cyrene's a 5-star Ice Remembrance support, but she's got this whole memosprite gimmick that makes her feel way more active than your typical buffer. Her Basic Attack generates 1 Recollection point while dealing 70% Max HP damage — not terrible, but the Enhanced Basic is where she shines with 3 points and AoE coverage (42% Max HP to single target plus 42% to everyone else).

The Memosprite Madness

Her Skill deploys a 2-turn Zone that adds 30% True DMG instances whenever allies get hit. Post-Ultimate? That Zone becomes permanent. The Ultimate itself costs 24 Energy and does something wild — summons a memosprite with 100% of Cyrene's Max HP, grants her an extra turn, AND activates every ally's Ultimate simultaneously. Both Cyrene and her memosprite enter Ripples of Past Reverie for +50% CRIT Rate.

But wait, there's more. Her Talent provides specialized Ode buffs that are frankly ridiculous. Trailblazer gets +16% Max HP to ATK conversion plus 72% CRIT Rate. Aglaea receives +70 Energy, +72% DMG, and 36% DEF ignore. These numbers are... aggressive.

Building the Ice Queen

World-Remaking Deliverer (4pc) is her bread and butter: +8% CRIT Rate, +24% Max HP for both her and the memosprite, plus +15% ally DMG. Pair it with Amphoreus, The Eternal Land (2pc) for +8% CRIT Rate and +8% ally SPD when the memosprite's active.

Target stats look like this: HP 6879, ATK 1726, SPD 189+ (180 absolute minimum), CRIT Rate 38%, CRIT DMG 182%. Main stats should be Body (CRIT DMG or HP%), Feet (SPD), Sphere (HP% or Ice DMG), Rope (HP%).

Her signature Light Cone This Love, Forever provides +18–30% SPD with Blank effect (+10–18% enemy DMG taken) and Verse effect (+16–28% ally CRIT DMG). When both effects are active, you get a massive +60–80% boost. The F2P option Memory's Curtain Never Falls gives +12% SPD and +16% ally DMG for 3 turns after using Skill — not bad, but you'll feel the difference.

Saber: When You Absolutely Need Things Dead

Saber's a 5-star Wind Destruction hypercarry with a 360 Energy cap, which should tell you everything about his playstyle. Basic Attack hits for 100% ATK, Enhanced Basic bumps that to 300%/370% motion values with +2 stacks. His Skill delivers 150% ATK plus 75% to adjacent enemies, granting +3 stacks or +14% DMG per stack.

Ultimate Devastation

The Ultimate costs 280 Energy but delivers 280% ATK to all enemies plus 10 instances of 110% ATK to random targets. That's 1380% single-target motion value if you're counting — and trust me, enemies will feel every bit of it.

Saber executing his Ultimate ability with multiple damage instances and AoE effects

His Talent gains 3 stacks per ally Ultimate (60% DMG boost for 2 turns), 3 from Skill, 2 from Enhanced Basic. Each stack generates 8 Energy, so the synergy's pretty smooth once you get rolling.

The Hypercarry Build

Wavestrider Captain (4pc) gives +16% CRIT DMG and +48% ATK on Ultimate with 2 Help stacks. Inert Salsotto (2pc) adds +8% CRIT Rate plus +15% Ultimate/Follow-up DMG when you're at ≥50% CRIT Rate.

You're aiming for ATK 2400+, CRIT Rate 60-80%, SPD 134+ for double actions, and maximize CRIT DMG wherever possible. A Thankless Coronation (S1) provides +72% CRIT DMG and +80% ATK that stacks to 160% if Max Energy ≥300.

Hyacine: The HP Buffer We Didn't Know We Needed

Hyacine operates as a 5-star Wind Remembrance support/healer with HP-based buffs that scale harder than they have any right to. Her Skill summons Little Ica while restoring 8% Hyacine Max HP + 160 to allies (10% + 200 to Little Ica). Ultimate costs 140 Energy and enhances healing to 10% Max HP + 200, entering After Rain state for +30% + 600 ally Max HP for 3 turns.

That's not a typo — she literally gives your entire team more HP.

The Little Ica Factor

Her Talent initializes Little Ica with 50% of Hyacine's Max HP. Here's the kicker: healing boosts Little Ica's DMG by 80% (stacking 3 times for maximum 240%). A2 Trace grants 100% CRIT Rate to both characters plus +25% Outgoing Healing when target HP drops below 50%. A6 Trace provides +20% Max HP when SPD exceeds 200, plus +1% Outgoing Healing per excess SPD point (maximum 200).

Building the Support Goddess

Warrior Goddess of Sun and Thunder (4pc) offers +6% SPD and +15% ally CRIT DMG for 2 turns on healing. Target SPD 200+ for that A6 boost, focus on HP scaling for Little Ica's durability. Her signature Long May Rainbows Adorn the Sky provides +30% SPD, memosprite follow-up DMG of 250–500% consumed HP, plus +36% enemy DMG taken.

Team Compositions That Actually Work

Cyrene Hypercarry: Cyrene/Castorice/Evernight/Hyacine maximizes Remembrance synergies through Recollection generation and Ultimate chaining.

Recommended team composition guide showing character synergies and optimal party setups

It's honestly disgusting how well this works.

Saber Dual-DPS: Saber + Sunday + Tribbie + Huohuo enables optimal Core Resonance stacking. Sunday provides 100% Action Advance plus 20% Energy, Tribbie adds RES PEN, and Huohuo generates 72 Energy with +40% ATK for 4 consecutive actions. The math checks out beautifully.

Hyacine Flex Teams: Castorice + Tribbie + Remembrance Trailblazer + Hyacine generates Newbuds through AoE heals while HP buffs amplify damage output. Blade teams particularly love the HP drain synergies with consistent Max HP buffs.

Pre-Farming: Don't Get Caught Slacking

Cyrene needs Travel Encounters x21, Adventure Log x8, Traveler's Guide x287, Sea Siren's Torn Fin x65 — total credit cost hits 3,888,100. Trace priority goes Memosprite Skill > Skill > Talent/Ultimate. Major Traces include Causality in Trichotomy (>180 SPD grants +20% ally DMG, excess SPD provides +2% Ice RES PEN maxing at 60%).

Saber prioritizes Ultimate > Talent > Skill with Knight of the Dragon (+20% CRIT Rate, Action Advance on Skill) and Crown of the Star (+50% CRIT DMG, +4% per Core Resonance stack maxing at 8).

Pull Verdict: Where Your Jades Should Go

Cyrene delivers T0.5 support for Remembrance teams with unique Chrysos Heir buffs and Ultimate chaining mechanics. E2 offers +12 starting Recollection plus +6% Zone True DMG per ally buff (maximum 24%) — that's whale territory but incredibly powerful.

Hyacine provides T1 sustain that's essential for HP-drain teams. E1 grants +50% ally Max HP in After Rain, E6 adds 20% All-Type RES PEN for endgame optimization.

Saber maintains T1 hypercarry status with consistent Wind performance. E2 adds 11.1% DPS through 15% DEF ignore, though Version 4.0 powercreep risks are real.

F2P Priority: Hyacine E0S0 if you've got sustain gaps → Cyrene E0S0 for Remembrance enablement. Whale Investment: Cyrene E2S1 → E6S1 for multiple team coverage, Hyacine E1S1 for immortal sustain.

FAQ: The Questions You're Actually Asking

Is Cyrene better than Saber in HSR 3.7? They're completely different roles — Cyrene's support, Saber's hypercarry DPS. Cyrene provides universal team value through Ultimate chaining, Saber excels in Wind-weak single-target content. Apples and oranges, really.

What are the best relics for Hyacine? Warrior Goddess of Sun and Thunder (4pc) with Giant Tree of Rapt Brooding (2pc). Prioritize SPD 200+, HP scaling, and Outgoing Healing Boost main stats.

When does the Honkai Star Rail 3.7 banner start? November 5, 2025 (UTC+8) with Cyrene's debut and reruns. Phase 2 kicks off November 26, 2025.

Is Cyrene's signature Light Cone worth it?This Love, Forever provides 30% SPD and team damage amplification. Offers 85-100% efficacy versus F2P alternatives at 70-80% — significant but not mandatory.

Can Hyacine solo sustain in Memory of Chaos? Absolutely. Through AoE healing, debuff cleansing, and Max HP buffs, she's incredibly reliable. E1 ensures immortal sustain with that +50% ally Max HP boost.

Should I save for 3.8 or pull in 3.7? Pull Hyacine if you're lacking premium sustain, Cyrene for Chrysos Heir teams. Consider skipping Saber since Version 4.0 might introduce stronger DPS options — though that's always a gamble in gacha games.
