Genshin Impact Spiral Abyss Guide 2026: How to Clear Floor 12 and Earn 36 Stars
The Spiral Abyss is Genshin Impact's premier endgame challenge and the largest recurring source of free Primogems in the game, awarding up to 1,200 Primogems per reset when you achieve a 36-star clear. Floor 12 in version 6.5 and 6.6 features level 95โ100 enemies and requires tight rotations, strong artifacts, and two well-built teams. This guide explains how to approach each floor, which team archetypes perform best, and the common mistakes that prevent full clears.
Spiral Abyss Basics and Reset Schedule
The Spiral Abyss consists of Floors 1 through 12. Floors 1 through 8 are permanent and only need to be cleared once for their rewards. Floors 9 through 12 reset on the 1st and 16th of every month, resetting your star count and introducing new enemy layouts. Each floor has three chambers, each with a time limit. Each chamber awards up to three stars based on how quickly you clear it. Maximum stars per floor is 9; the full Abyss maximum is 36 stars across Floors 9โ12. The Primogem reward is 600 per cycle for 36 stars (1,200 per month total across both resets).
Team Building: Two Teams, Distinct Roles
The Abyss splits your roster into two separate four-character teams for Chambers 1 and 2 of each floor (Chamber 3 allows you to choose either team). You cannot repeat a character across both teams. This means you need at minimum eight well-built characters and ideally two distinct elemental archetypes to handle whatever enemy types the current rotation presents. A common split is one Hydro reaction team (such as Neuvillette/Furina or Childe/Xiangling) and one Electro/Dendro reaction team (such as Alhaitham/Nahida/Raiden). Check the current floor 11 and 12 enemy list before building your split โ some rotations heavily favor Cryo or Physical damage.
Floor 12 Strategy for Version 6.5/6.6
In version 6.5 (April 2026), Floor 12 rewards teams with Lunar Crystallize in the first half and Nightsoul or high-damage teams in the second half. Bring a healer specifically for Chamber 3's Radiant Moongecko boss to counter its Radiant Cocoon mechanic. In the second half, Tenebrous Mimiflora enemies have void wards that are best cleared with Nightsoul application or Lunar teams. If you lack Nod-Krai characters, a high-damage Vaporize or Quicken team with Kazuha for crowd control can substitute. Version 6.6 adjusts the specific enemies but maintains a similar template โ check game8.co or HoYoLAB for the current chamber breakdown each cycle.
Artifact and Investment Requirements
Floor 12 is designed for characters with well-developed artifacts โ expect to need at least a 200+ CV (combined Crit Value: Crit Rate x2 + Crit DMG) on your main DPS, fully leveled weapons at refinement 1+, and talent levels at 8โ10 for your primary damage talents. Characters should be fully ascended to level 90. If you are not consistently 36-starring, check your artifacts first โ a gap in Crit substats is more commonly the issue than team composition. Use the Abyss buff for the current cycle (visible on the Abyss screen) to your advantage; some cycles offer element-specific buffs that can significantly increase your damage.
Common Mistakes and How to Fix Them
Mistake 1: Not using the time properly โ the star threshold is based on time remaining when enemies are defeated, so practice your rotation outside the Abyss first. Mistake 2: Splitting supports unevenly โ both teams need a reliable healer or shielder; do not stack all your supports on one team. Mistake 3: Ignoring the Ley Line Disorder โ every floor has a modifier that affects gameplay; read it before entering. Mistake 4: Using burst-dependent teams without enough Energy Recharge โ always verify your support characters meet their ER thresholds (typically 160โ200% for burst-on-cooldown characters). Mistake 5: Not knowing enemy weaknesses โ some Floor 12 enemies have shields or void wards requiring specific element breaks.
Floors 9โ11: Consistent Star Farming
Floors 9 through 11 are more forgiving than Floor 12 but still reset monthly and contribute 900 Primogems per cycle toward the 1,200 maximum. Clear these with your strongest team first (usually first half of Floor 12 team) to guarantee stars, then send your second team through. Floors 9 and 10 are generally clearable with AR 45 characters and basic artifacts. Floor 11 introduces Fatui and elemental shields โ bring characters who can break shields efficiently (Fischl for Cryo shields, Barbara/Xingqiu for Pyro shields). If you are stuck on Floor 12, full-clearing Floors 9โ11 still nets 900 Primogems per reset, which is a meaningful free income.
FAQ
How often does the Spiral Abyss reset?
Floors 9โ12 reset on the 1st and 16th of each month. You can earn the full star rewards twice per month, for a maximum of 2,400 Primogems per month across both resets.
What Adventure Rank do I need to access the Spiral Abyss?
The Spiral Abyss is accessible from AR 20 onward, but Floor 12 is only practical for AR 45+ players with fully built characters and strong artifacts.
Can I clear Floor 12 with only 4-star characters?
Yes, but it requires excellent artifact investment and team composition. Characters like Xiangling, Fischl, Xingqiu, Bennett, and Beidou are 4-stars who regularly contribute to 36-star clears in community showcases.
What happens if I only get 33 or 34 stars instead of 36?
The Primogem rewards are tiered: you earn Primogems for reaching star thresholds (50, 100, 150, 200, etc.) within Floors 9โ12. Falling short of 36 stars still awards a partial Primogem reward based on how many stars you accumulated.
Does my Spiral Abyss progress carry over between resets?
No. Your stars and chamber completion for Floors 9โ12 reset completely on the 1st and 16th. Floors 1โ8 are permanent once cleared and do not reset.
