F2P Sandrone Spiral Abyss 12 lineup | August 2026
Updated on 2026-08-18: 7.0 Floor 12 live. First-half Ley Line is Superconduct +200% and Stellar-Conduct +75%. Second half is Normal Attack Pyro +75%. Put Sandrone on the first clock.
Half | Team | Lineup | Job | Cost |
|---|
12-1 / 12-2 / 12-3 first | Sandrone Conduct | Sandrone C0 / Qiqi 70 / Beidou C6 / Alyosha | On-field Fagio beams + Polestar stacks | 1 limited (Sandrone) |
12-1 / 12-2 / 12-3 second | Mizuki Swirl | Mizuki / Odette / Cryo Traveler / Faruzan | Off-field Cryo, then Anemo drive | 2 limited (Mizuki, Odette) |
Sandrone owns first half because the Ley Line pays Conduct. Mizuki owns second half because Pipilpan Idol, Jadeplume Terrorshroom, and Maguu Kenki die to Stellar-Swirl ticks.
Sandrone: C0, Level 90, Mailed Flower R5. Target ~2,200 ATK, 310 EM, 60% CRIT Rate, 220% CRIT DMG, 110% Energy Recharge.
Qiqi: Level 70 is enough. 4pc Scroll of the Hero of Cinder City, Healing Bonus circlet, ~210% Energy Recharge.
Beidou: C6. 4pc Noblesse Oblige. Skill and Burst to 12. Energy Recharge on every piece you can spare.
Alyosha: Free 7.0 event Electro. Favonius Lance R5 at Level 70. One Heart of the Furnace piece is enough until you finish his set.
Mizuki: Level 90. 2pc Wanderer's Troupe + 2pc EM. ~710 EM, 52% CRIT Rate, 250% CRIT DMG. Skill 10, Burst 8.
Odette: Level 80. 4pc Heart of the Furnace, ATK / ATK / CRIT Rate. ~2,400 ATK. Play EE. Full kit sits on the Odette best teams page.
Cryo Traveler: 2pc Gladiator + 2pc Shimenawa. Skill then Burst, then leave. Build notes live on the Cryo Traveler guide.
Faruzan: Level 90, 4pc Instructor, ~218% Energy Recharge. She exists to hold Q and hand Mizuki the Anemo shred.
A single Conduct window on Floor 12 first half prints 160k–190k ticks, then a 900k Fagio overdrive hit when Polestar, Noblesse, and the +75% Ley Line stack. Follow-up beams in that same rotation push the window past 1.4 million.
Floor 12 rooms this cycle
Chamber | First half | Second half | What you do |
|---|
12-1 | Ruin Sentinels → Perpetual Mechanical Array | Construction Mek (Pneuma) → Icewind Suite | AoE first, then hold Burst for the Array. Interrupt Coppelius’s Cryo shield with Ousia if you have it. |
12-2 | Chimeric Horned Bear + Winged Lion | Iniquitous Baptist → Cryo Abyss Mage | Cryo shreds the Lion’s Electro shield. Baptist shields go Pyro → Cryo → Electro. Swirl eats the shields. |
12-3 | Battle-Hardened Precursor / Secret Source Matrix | ASIMON → Pipilpan Idol | Solo tank on first half. Break the Idol’s hat conjurations, then dump Mizuki field time. |
Benediction of the Abyss before 12-2:
ATK +20%, lasts the floor
DEF −15% / ATK +40%, lasts the chamber
Burst heals 30% HP, lasts the chamber
Take ATK +40% when you chase the 900k Fagio hit. Take ATK +20% when Sandrone already sits at 2,200 ATK and you want the floor-wide buff.
How to play the F2P Sandrone half
Step 1: Alyosha Skill + Burst. Favonius particles refill Beidou. Drop Heart of the Furnace if he wears it.
Step 2: Beidou Burst, then Skill. Noblesse 20% ATK lands on Sandrone. C6 Beidou holds Electro on the field so Conduct keeps stacking.
Step 3: Qiqi Skill. Scroll shares Elemental DMG. Her Burst is optional. You want the heal so Mailed Flower’s ATK stays up.
Step 4: Swap Sandrone. Charged Attack summons Fagio in Decoding mode. Hold the beam until Decoding Power hits 100. Skill resets Fagio when it falls into Overdrive. Burst at the end of field time. The second Prism Shot and the Convective Inhibition Ray both count as Stellar-Conduct inside a Polestar Field.
Step 5: Repeat. Sandrone field time is 10–13 seconds. Qiqi at 70 holds the team above 20k HP through 12-3.
Talent order on Sandrone: Normal Attack (Charged) → Burst → Skill. Stop at 80/90 if resin is tight. A4 converts ATK into EM (cap 160 at 2,000 ATK), so ATK% goblets beat Cryo goblets. 4pc Disenchantment in Deep Shadow is the set: +18% ATK, +80% Superconduct, +40% Stellar-Conduct, +16% CRIT Rate against Conduct-affected targets.
Mailed Flower R5 (565 Base ATK, 110 EM, +24% ATK / +96 EM after Skill or a reaction) is the F2P claymore that matches this team. Craft Tidal Shadow if you missed the event. Signature A Teaspoon of Transcendence waits until C0 and the supports are finished.
How to play the Mizuki and Odette half
Step 1: Faruzan Burst. Instructor +120 EM for 8s. Hold her on the field only long enough to land Q.
Step 2: Odette Skill, then the follow-up Coda inside 6 seconds. EE is 2.3s. Her clone ticks Cryo every 2s for ~20s and converts Cryo Swirl into Stellar-Swirl. Weapon and Furnace numbers sit on the Odette build guide.
Step 3: Cryo Traveler Skill + Burst, then swap. You need the extra Cryo applicator because Mizuki cannot start Stellar-Swirl alone.
Step 4: Mizuki on-field. Enter Dreamdrifter. Three to four EM-scaled hits, then the vortex. 1–2 Swirls stay thin. 3+ Swirls fatten the vortex (~×3). Icewind Suite and Pipilpan Idol fall to those ticks, Ley Line or not.
Step 5: Refresh Faruzan Q every rotation. If Traveler is stuck on the Sandrone half, swap Qiqi or C6 Diona into the Mizuki side. The Yumemizuki Mizuki Stellar Swirl build covers the no-Traveler sheet.
Single Swirl hits land 130k–180k. A fat vortex on Maguu Kenki or Pipilpan Idol crosses 210k–410k. Yae Miko stays on the premium Conduct page.
Slot swaps if your roster is thinner
No Beidou C6: Free-event Alyosha C6 plus Kuki or Fischl. Conduct starts. Personal DPS drops.
No Alyosha: Bennett or a second Electro 4-star. You lose the free Furnace holder.
No Odette: Cryo Traveler already enables Swirl. C6 Diona or Qiqi fills the fourth slot. Pull Odette if you want the 60% Swan transfer and the Coda. See Snezhnaya prep before you spend the guarantee.
No Mizuki: Put Cryo Traveler on-field as the cheap Conduct carry on second half. Clear time gets worse. First-half speed buys the 36-star.
No Mailed Flower: Tidal Shadow with Qiqi. Wolf’s Gravestone if you own it.
Premium Conduct (Sandrone / Yae Miko / Odette / Qiqi) sits at 189k team DPS on F2P weapons. This page is the 1-cost path that 36-stars the August rooms.

FAQ
Can F2P Sandrone 36-star Spiral Abyss 12 in August 2026?
Yes at C0 with Mailed Flower, Qiqi 70, C6 Beidou, and free Alyosha on first half. Second half wants Mizuki and Odette, or Mizuki plus Cryo Traveler if Odette is on the other clock.
Does Sandrone need her signature for Floor 12?
No. Mailed Flower R5 or Tidal Shadow clears the August first half. A Teaspoon of Transcendence is a personal stick. Finish Beidou C6 and Odette C0 first.
Why put Mizuki on second half instead of another Conduct team?
Floor 12 second half this cycle is Icewind Suite, Iniquitous Baptist, Jadeplume Terrorshroom, and Pipilpan Idol. Stellar-Swirl breaks shields and multi-wave rooms. The Pyro Normal Attack Ley Line is for Arlecchino. You can ignore it.
What artifacts does F2P Sandrone use?
4pc Disenchantment in Deep Shadow, ATK% / ATK% / CRIT. Farm until 2,000+ ATK so A4 caps EM. A weak Disenchantment set beats 2pc ATK mixes on Conduct damage.
Is Odette required for the Mizuki half?
Cryo Traveler already enables Stellar-Swirl. Odette is the buffer: clone, 60% Swan transfer, Heart of the Furnace 50% team Stellar. Pull her if you play Sandrone or Mizuki past this cycle.
Conclusion
The F2P Sandrone Spiral Abyss 12 team in August 2026 is Sandrone / Qiqi / Beidou / Alyosha on first half and Mizuki / Odette / Cryo Traveler / Faruzan on second half. Build Disenchantment and Mailed Flower on Sandrone, Scroll on Qiqi, Noblesse on Beidou, Instructor on Faruzan, Furnace on Odette. Bookmark the page for the next reset. Top up Genesis Crystals on BitTopup when pity sits 10 to 20 pulls short of Odette or Sandrone.
