The verified chapter structure
TEAM HORAY’s official Steam material describes a complete journey across six chapters. Across that campaign it lists more than 60 enemies and more than 10 unique bosses. Those totals are the reliable public framework; the official store page does not expose a complete table of current chapter names, rooms, rewards, and bosses.
The saved community boss archive is organized by Stages 1 through 5 and separately records Chapter 4 story encounters. That organization is useful for preparing recognizable encounters, but it should not be silently converted into an official six-row chapter table. Stage labels, story chapters, and the full-release chapter count are related progression views, not necessarily interchangeable names.
Archived stage index
The translated archive places Blackhand Mogdi, Ordner, and Haj under Stage 1. Lataka and Lerid appear under Stage 2, followed by Erma and Pantaxis under Stage 3. Ascard is the recorded Stage 4 boss, while Cobes, Kraz, and Qliphoth are grouped under Stage 5.
It also lists mini bosses for the first four stages and separate Chapter 4 story encounters. Treat these names as a navigation index, not as a complete current encounter table.
| Archive segment | Recorded encounters | Evidence use |
|---|---|---|
| Stage 1 | Blackhand Mogdi, Ordner, Haj | Archived index; names need live confirmation |
| Stage 2 | Lataka, Lerid | Archived index; names need live confirmation |
| Stage 3 | Erma, Pantaxis | Archived index; names need live confirmation |
| Stage 4 | Ascard | Archived index; chapter mapping is not official |
| Stage 5 | Cobes, Kraz, Qliphoth | Archived index; names need live confirmation |
| Chapter 4 story | Prison Warden, Core | Story index, not a complete route table |
Plan a chapter, not one room
A chapter route tests ordinary waves, elites, resource decisions, and a finale. Avoid planning around an isolated room if the setup cannot maintain safe clearing before it arrives. A coherent route needs enemy access, crowd control or separation, survival, and enough inventory flexibility for later rewards.
Preserve inventory flexibility early. An Artifact that fills awkward cells may solve the current room but prevent a later core and Tablet relationship. As the route becomes clearer, consolidate around one trigger and remove pieces that do not contribute to survival, access, damage, or economy.
Need a specific Boss strategy?
This page keeps Boss names as a chapter index. For attack patterns, phase changes, safe damage windows, and weapon-specific counters, continue to the Sephiria Bosses guide. Keeping those details in one page avoids duplicating or conflicting fight advice.
Permanent progress between chapter attempts
Sapphires earned in the dungeon support Destiny Inscription outside the run. The tree can open weapons, Artifacts, Talent Points, inventory improvements, and other options. Decide whether the next attempt needs a new tool or better access to a familiar route before spending.
Some community records connect chapter progress to additional unlocks. A captured Staff video requires completion of the fourth chapter before its training path, and the Costume archive associates Fairy of Fortune with completing Chapter 4: Fragment. These are version-sensitive community records, so current node and unlock text should be checked before treating them as requirements.
What is not verified
This research archive does not contain a complete official list of all six current chapter names, every room sequence, a fixed number of encounters per chapter, or official drop rates. It also does not establish that every Stage label in the translated boss archive maps one-to-one onto the six chapters described at full release. Those gaps are left visible rather than filled with names inferred from old videos.
Use the boss page for detailed archived patterns and the Secret Rooms page for wall-scanning routines. For live progress, the current client and TEAM HORAY announcements take priority over an older community table. That keeps route guidance useful without turning incomplete evidence into a false campaign map.
