Boss Intelligence Centre
Patch-aware official boss dossiers separating verified rematches and mechanics from identities that still require controlled research.
The Boss Intelligence Centre consolidates every canonical boss record into one evidence-controlled operational view. It does not convert a trailer appearance or historic bug fix into an invented route, weakness, phase list or reward table. Every dossier now has source-verified imagery: official publisher media where available, or an attributable community gameplay capture when no exact official portrait exists.
Phase 16.2 · Complete boss visual intelligence
Boss Intelligence Centre
A patch-aware dossier for every officially supported boss record—separating confirmed rematches and mechanics from identities that still require controlled in-game research.

How to interpret a dossier
Section titled “How to interpret a dossier”- Verified rematch means the official Memory Fragment location and first-defeat activation rule are documented.
- Official rematch — location unresolved means an official notice confirms the rematch exists, but the guide has not recorded the Memory Fragment location.
- Official mechanic evidence means patch history confirms specific encounter behaviour while route and completion evidence remain incomplete.
- Official identity only means the boss is officially named, but current-release encounter intelligence still requires verification.
- Official Fan Kit portrait means the image comes from a named publisher asset and maps unambiguously to the exact canonical boss record.
- Credited community gameplay capture means no exact official portrait was available; the original creator, page, upstream image and boss-identity evidence are retained in the media registry.
Media boundary
Section titled “Media boundary”The official Fan Kit supplies clean, named screenshots for White Horn, Staglord, Reed Devil and Queen Stoneback Crab. The remaining 13 dossiers use credited gameplay images from their original creator pages. Every local WebP retains a source page, upstream image URL, creator credit, exact identity note, dimensions and fan-content usage basis. Anonymous image-search downloads, unidentified creatures and fantasy lookalikes remain prohibited.
Awakened Caliburn receives an extra identity check: the community source calls the encounter Corrupted Caliburn, while Pearl Abyss Patch 1.06 calls the matching Abyss chamber encounter Awakened Caliburn. The delivered image is therefore a label-free subject crop, and the two canonical dossiers remain separate.
Variant rule
Section titled “Variant rule”Shared words do not prove that two boss names describe the same encounter. White Horn remains separate from Clockwork White Horn, and Awakened Caliburn remains separate from Corrupted Caliburn, unless an official source explicitly links them.
Research hand-off
Section titled “Research hand-off”Use the Research Queue Centre to record current-patch tests. A useful submission includes the patch, platform, save state, repeatable start point, ordered observations, completion evidence and a clear separation between direct observation and interpretation.
