Sephiria Constellations Guide: Zodiac Rooms and 100% Completion
This sephiria constellations guide covers how zodiac rooms hide in the tower, how blue markers reveal them, and how visits count toward 100%.
What Constellation Rooms Are
Scattered through Sephiria’s tower are hidden standalone rooms dedicated to the zodiac constellations. These are not part of the normal critical path between you and the next boss; they are optional discovery rooms themed around the star signs, and the game does very little to point you at them. Each constellation exists as its own hidden room, and reaching the room’s blue marker — a frame at the heart of the space — reveals that constellation. That reveal is what registers your visit.
For completionists this matters a great deal. Constellation visits are tied to achievements and to 100% completion, which makes these rooms one of the few categories of content in the game you cannot simply bulldoze past on raw combat skill. You have to find them, one by one, across many descents — and finding them uses the same trained eye you sharpen while hunting ordinary secret rooms. If you have read our secret rooms guide, you already know most of what you need. This guide covers the rest: what these rooms are, how to find them, and how to track a full set.
How Constellation Rooms Differ From Secret Rooms
| Aspect | Ordinary Secret Room | Constellation Room |
|---|---|---|
| Discovery method | Suspicious wall segment (cracks, discoloration, dead ends) | Hidden standalone room, found with the same toolkit |
| What triggers the reward | Looting the room’s contents | Reaching the blue marker or frame |
| Ties to progression | Your current run’s economy | Achievements and 100% completion |
| Skippable? | Yes, at your own cost each run | Only if you are not chasing 100% |
The two room types share DNA — both hide behind the tower’s walls, and both reward players who attack suspicious geometry and question dead ends — but they serve different purposes. A secret room pays out inside the run; a constellation room pays out across your entire profile. That difference should shape how you prioritize: early in a descent, loot freely; when you spot a constellation room, treat it as permanent progress and never leave it unrevealed.
How to Find Constellation Rooms
Constellation rooms are hidden standalone rooms, which in practice means the same detection routine you already run for secret rooms. Scan every floor’s perimeter for cracked or discolored wall segments. Attack every dead end. Watch the minimap for gaps and pockets that do not match any door you have opened. The difference is scale: because each zodiac constellation exists as its own room, a full completion means repeating this process across many runs. You are not looking for one hidden room; you are looking for a whole category of them.
Once inside, the room announces its purpose. Walk to the blue marker or frame — the visual centerpiece of the space — and the constellation reveals itself. That reveal moment is the point of no return for credit: a room found but left without touching the marker has not been banked. Make contact, watch the reveal, confirm it registered, and then continue your descent. The few seconds it takes is the entire cost of a permanent piece of completion progress.
Constellations and 100% Completion
Sephiria’s 1.0 launch on July 31, 2026 delivered the full achievement set, and constellation visits sit inside it as a distinct, required category. A complete 100% achievements guide exists on Steam, maintained by the Chinese-language community, and it treats constellation visits as mandatory rather than optional flavor — consistent with what players chasing full completion report. The set is also a natural example of why Sephiria’s completion chase has legs: the rooms are discrete, findable, and satisfying to tick off, but they are spread across procedurally arranged floors, so no single run finishes the job. You are accumulating star signs, not clearing a checklist in one sitting.
Tracking Your Constellation Progress
| Method | What It Tells You | Limitations |
|---|---|---|
| Steam achievements page | Which constellation-tied achievements have unlocked | Wording can be oblique; does not map to floors |
| In-game completion indicators | Overall completion progress where the game exposes it | Detail and placement vary by patch |
| Kean’s Sephiria Compendium | Community-verified data on hidden rooms and finds | Requires cross-referencing against your own play |
| A personal checklist | Exactly which constellations you have revealed | Manual upkeep, but the most precise view |
Because the tower reshuffles every run, tracking is by constellation, not by location — you are checking off star signs, not map coordinates. A simple personal checklist kept beside the achievements page is the approach most completionists settle on. Remember that patches have been frequent since launch — version 1.0.25 and beyond arrived by August 2026 — so verify current reveal and tracking behavior against the official Discord before trusting an old note.
What Each Constellation Category Gives
| Constellation Milestone | What Visiting Contributes |
|---|---|
| An individual zodiac reveal | Ticks that constellation toward the full set; feeds achievement progress |
| Completing a themed group | A meaningful milestone wherever the game groups the signs |
| The full constellation set | A required pillar of 100% completion |
Keep expectations calibrated here. The reliable, verified payoff of constellation rooms is completion and achievement progress — not combat power. If a given patch also attaches gameplay bonuses to reveals, treat that as something to confirm in the current patch notes, the Compendium, or the official Discord rather than a promise. The persistent value is the permanent check in the completion column.
Tips for the Hunt
Pair your constellation hunt with your ordinary secret room routine — same wall scan, same minimap check, same dead-end policy — and you will find both categories of hidden room faster than players who treat them as separate chores. Play co-op when you can and assign one player to perimeter duty on each floor; four sets of eyes find more standalone rooms than one, and the tower is equally secretive in multiplayer. And when you are stuck on a specific constellation, ask in the official Discord or on r/sephiria — hidden-room finds circulate through the community quickly after every patch, and someone almost always has a fresh screenshot.
Frequently Asked Questions
How many constellations are there to find?
The full zodiac set exists as hidden rooms in the tower, but do not rely on memory for the exact count in your build — check the achievements page or Kean’s Sephiria Compendium, which tracks the live state of the game as patches land.
Do I have to reach the blue marker, or is entering the room enough?
Reaching the blue marker or frame is what reveals the constellation. Entering and leaving early risks no credit at all, so always walk to the marker and watch the reveal before moving on.
Do constellation visits carry over between runs?
Yes. Revealed constellations count toward your profile-level completion and achievements rather than a single run, which is why your checklist shrinks permanently over time even though the tower reshuffles itself every descent.
Can I hunt constellations in co-op?
Yes, and it is efficient — the tower holds the same hidden rooms for the whole party, so a coordinated sweep by four players finds more standalone rooms than one. Agree beforehand who reports which reveals so everyone’s checklists stay accurate.
