Clear the Spiral Abyss with the roster you already own.
The Abyss resets on a schedule, and the stars you miss this cycle are simply gone. Generic floor-12 guides assume a stacked account — but you need two teams that work for both halves, built from what you've actually leveled. Chamber details change; the way you assign a real roster does not.

Two halves, two teams — plan them together
Each chamber splits into a first and second half, and you field a different team in each. The mistake is optimizing one team and throwing the leftovers at the other. Plan both halves as a pair so your strongest characters aren't fighting over the same slot.
Supports can sometimes be shared across cycles if you rebuild, but within one run they cannot. If your only strong healer is locked into half one, half two needs a different survival plan — a shielder, a different healer, or a team that simply does not get hit. That trade-off is the actual puzzle.
Read the chamber before you pick
Each reset brings its own enemies and conditions. Single concentrated targets reward different teams than scattered waves; some halves pressure you on time, others on survival. The right team answers what that specific chamber is actually asking.
You do not need a patch-by-patch encyclopedia to use this. Look at whether the half is one boss, a line of elites, or a swarm; whether the blessing rewards a playstyle you already run; and whether a mechanic punishes standing still. Then pick the built team that matches, not the famous team that does not.
Speed and survival both count
Abyss scoring rewards clearing fast, but a team that dies clears nothing. The goal is the fastest lineup you can field that still survives the chamber — which depends entirely on how invested your characters are. Under-invested hyper-carry teams look great in videos and fold on your account. Over-stacked sustain teams live forever and miss the timer. Your build levels decide which side of that line you are on.
Blessings are a multiplier, not a team identity
The chamber blessing should tilt a close call, not force you onto characters you have not built. If the blessing wants a reaction you already play, lean in. If it wants a roster you do not have, ignore it and play your invested core — a well-built off-blessing team still outruns an unbuilt on-blessing fantasy. Check the current-cycle page for a short, non-rotting note on what this reset is asking, then come back to this role logic.
Stars you miss this Lunar Phase do not carry over
Official: the Abyss Corridor (lower floors) is one-time; the Abyssal Moon Spire (floors 9–12) Lunar Phase refreshes on the 16th of each month. Unclaimed rewards do not carry over. Imaginarium Theater resets on the 1st — a different mode, not a second Abyss cycle.
A practical cadence: on the 16th, assign two teams from the roster you have now. Spend resin until the next 16th on the one or two bottlenecks that actually cost you stars — a talent, a weapon, a survival slot — not on a third vanity build. Luminary regenerates the plan from the live rotation so you are not doing that from memory.
Full-clear is an investment problem more than a character problem
In-game format: 12 floors, 3 chambers each, up to 3★ per chamber. Floors 9–12 (Abyssal Moon Spire) award 36★ for a full Lunar Phase clear, with two halves per chamber. That structure does not require the newest units; it does require two teams you have actually built. If you cannot name a second driver with real artifacts, the next wish is often not the bottleneck — resin assignment is.
Before you enter the current cycle
Use this on reset day. It stays valid no matter which enemies the chamber spawned.
- Two teams are assigned as a pair — your best driver is not booked on both halves.
- Each half has a survival plan (healer, shielder, or a team that does not get hit).
- You looked at the chamber: boss vs. swarm, timer vs. chip damage, blessing yes/no.
- Weapons and artifacts on both teams are the ones you actually upgraded, not placeholders.
- You know which one bottleneck (talent, weapon, or support) would buy the most stars this cycle.
- If you miss stars, you will farm that bottleneck — not pull a random banner and hope.
How Luminary plans your Abyss run
Luminary reads the live Abyss rotation and your synced roster, then maps your strongest builds onto both halves.
- Current enemies and chamber conditions summarized at a glance
- Two teams built from characters you own and have invested
- A half-by-half plan instead of a one-size lineup
- Suggestions to push for full stars as your roster grows

Questions, answered.
Field two teams that each clear their half quickly without dying, matched to the current chamber's enemies and conditions. Most accounts don't need 'perfect' characters — they need their best-invested ones placed in the right half. Luminary plans both halves from your actual roster and the live rotation.
Official (HoYoverse Help Center): the Lunar Phase of Spiral Abyss refreshes on the 16th of each month. Imaginarium Theater resets on the 1st. Claim rewards before refresh — they do not carry over. Confirm exact timing on the in-game countdown.
No ranking is implied here. Full-clear is a function of two invested teams matched to the in-game preview, not of owning the newest names. Four-star and standard characters are valid slots when they are built.
Put that team on the harder half and build a simpler second core: a driver you have already leveled, a survival slot, and whatever enablers you own. The second team does not need to be fashionable; it needs to finish. Resin on that second driver usually returns more stars than another constellation on the first.
Cycles vary, but waiting is how reward currency evaporates. Play the Lunar Phase in front of you with the roster you have, take the stars you can, and spend resin until the next 16th on the bottleneck that stopped you. The current-cycle page is a sourced snapshot into this guide, not a reason to freeze progress.
Use the thin this-cycle Abyss page for a short, dated snapshot, then come back here for how to assign your roster. Chamber names change; two-half planning does not. Luminary also reads the live rotation in-app so the snapshot and your teams stay in sync.
