Boss Rush is confirmed; its full rules still need capture.
Steam confirms Boss Rush unlocks after the final boss. The supplied current-release recording reaches its Boss Rush segment at 52:24; use that evidence for the unlock and encounter context, while treating recovery values and reward totals as unverified until captured in game.

What the current recording confirms

- Boss Rush Mode is an official post-final-boss feature on the Steam store page.
- FEEDING THE BLADE is the achievement for beating Boss Rush.
- The supplied full-boss recording enters a Boss Rush segment at 52:24 and continues to the Maakyuurii encounter at 56:57.
- Plan the mode only around confirmed loadout and encounter evidence; the supplied material does not provide a complete numeric recovery table.
- Record a current patch/date alongside any future healing, reward or reset observation.
What the Boss Rush recording does and does not show
The supplied recording enters the mode at 52:24 and reaches Maakyuurii at 56:57. It confirms a real current-release segment, not a complete encounter order or a universal rules table. The recording does not capture enough menu state to publish a recovery percentage, reward total, carried-build rule or named opener list.
- Use the recording timestamp to confirm that you reached the mode, not to infer every encounter in your version.
- Treat a patch-date run as its own evidence set if its boss names, recovery screen or rewards differ.
- Do not use an old Demo route or an unsourced boss list as a Boss Rush sequence.
Prepare a useful first verification run
- Before entering, record the current game build/date, equipped sword and Max Heal Ore count.
- After each encounter, capture the boss name, recovery UI and any reward screen before continuing.
- Use a sword you can explain from the recorded seven-sword route; the supplied material does not justify a universal tier list.
- Turn a failed run into evidence: note the point where health, stamina or an unfamiliar pattern ended the attempt instead of assigning unsupported stat breakpoints.
Methodology: keep the mode evidence-led
Boss Rush is an endgame completion target, but the current pack only verifies the unlock context, a recording segment and the FEEDING THE BLADE achievement. Until a complete current-patch capture includes menus and post-fight screens, the page gives a collection checklist rather than a fabricated sequence, percentage or build prescription.
- Collect the three recorded Max Heal Ores before treating a run as a comparison test.
- Use the Boss hub to identify recorded story encounters, while keeping the actual Boss Rush order separate until captured.
- Save a timestamped recording of any new run so future route advice can name the build and patch it came from.
What still needs a Boss Rush capture
The supplied recording confirms the mode segment and its navigation timestamps, but it does not provide a complete encounter-by-encounter ruleset. Until a current-patch run records the in-game sequence and recovery UI, this page limits advice to resource planning rather than naming an unsupported order or reward table.
- Enter with a stable sword and a healing budget that you can explain from your own menu state.
- Record the boss name, start time, post-fight recovery and any reward screen for each encounter.
- Treat any recovery percentage, reset rule or reward total as versioned evidence; do not generalize from one run.
- Use the current sword and Max Heal Ore pages for preparation, then update this section after a complete Boss Rush capture.
Evidence grading: what is verified vs. open
Steam confirms the unlock condition and FEEDING THE BLADE achievement. The supplied recording confirms a current-release Boss Rush segment at 52:24. Recovery values, reward totals, carried-build behavior and the full encounter order are still open because the supplied material does not capture the necessary UI evidence.
