PhylaXron — Taishi's FBD 14 gauntlet

Seol's FBD 14 run on PhylaXron is the deepest record of In Falsus's semi-boss chart anywhere in text: 3,317 notes reached judgment before the miss gauge fell to −12 and the run closed DIVE FAILED. The result card's IOTA slot reads ASSIST MODE, so this was an Assist Mode run — the judged-note count still describes the chart itself, but the score is not a clean baseline. This page walks the chart the way the run played it — including the honest ending.

Name check (2026-09-22): the song is PhylaXron — Taishi is its composer. Seol's source video lists the pair artist-first ('Taishi - PhylaXron'), which is where the misreading 'Taishi chart' came from; the in-game title card and both community wikis print PhylaXron.

Sources

All numbers are read off the result card at t≈235 (2026-09-20); the EARLY 163 / LATE 60 split beside NEAR is printed on the card itself. The same card's IOTA slot prints ASSIST MODE — an Assist Mode run, disclosed up front. Because the run ends short of the chart's end, the note total is strictly higher than 3,317 and none is claimed.

PhylaXron sits deep in In Falsus's late game — the community files it as a semi-boss. This page keeps to chart mechanics, but if you are mid-story, the chart's existence and tier are themselves spoilers.

The blank card

  1. 1

    A first entry

    The song-select card shows the PhylaXron jacket — the title reads PhylaXron, the artist line Taishi — with a red FORBIDDEN 14 badge and an empty HIGH SCORE row: Seol is sightreading. The tier badge alone tells you this is one of the hardest regular charts in the game.

    Deck locked, field loading

    The CONNECT deck is in and the field idles at 000'000'000 with the A S D F rail visible. On FBD charts the deck is survivability first — the miss gauge is the real opponent, as this run will prove.

    The full-width opener

    At 000'982'159 a cyan field note already spans all six lanes. PhylaXron does not warm up — wide fields are part of its vocabulary from the first seconds, and they never leave.

The first half piles up

    Twinned beams

    Paired EXACT rows ride twin cyan beams at 009'550'372. The early game is generous by FBD 14 standards — the first minute is where you bank chain for the squeeze to come.

    The curve

    A long purple field sweeps across the left lanes at 022'806'313. Curve fields force you to re-grip mid-hold — this is the first moment the run looks genuinely effortful.

    First honest labels

    LATE and BREAK appear beside gold hex holds at 030'493'378. Even a clean sightread leaks judgment labels here; the gauge is still deep, but the chart has drawn first blood.

The semi-boss squeeze

  1. 7

    Rebuilding the chain

    Three EXACT labels answer a violet slab at 037'369'691 and the link counter climbs again. Mid-chart, PhylaXron alternates pressure and relief in short, deliberate waves.

    The wide wall

    NEAR and BREAK mark a wall of cyan and pink beams at 043'907'972. Wide-note stacks are where the miss gauge starts its long decline on this run — watch the HUD after this frame.

    Deep water

    A purple hold and pink side fields split the lanes at 054'646'546. Past the halfway mark, every lane wants attention at once — this is the semi-boss framing earned.

Past the point of no return

    The gauge runs out

    At 073'146'127 an EARLY NEAR and a BREAK sit inside an otherwise EXACT stream. The judgments are still mostly clean — but the miss gauge is now the countdown that matters.

    The last field

    Twin full-length cyan and pink fields close the run's final stretch at 077'659'891. Moments later the gauge bottoms out — the chart ends the run before the run ends the chart.

FAQ

What is PhylaXron, and who is Taishi?

PhylaXron is a late-game FORBIDDEN (FBD) chart composed by Taishi, filed by the community under semi-boss — the tier just below the secret songs. Mind the name trap: Seol's source video prints the pair artist-first ('Taishi - PhylaXron'), which is why some early text records call the song Taishi — the in-game result card and both community wikis print the title as PhylaXron. As of 2026-09-20 this page was the first text walkthrough of the FBD 14 chart; the community wikis list the song's levels and the MIN/EVO/ULT note counts, but the FBD 14 total remains unpublished.

How many notes does PhylaXron FBD 14 have?

More than 3,317. The run on film judged exactly 3,317 notes — EXACT 2437 + 323, NEAR 223, BREAK 334 — before failing near the chart's end, so the full total is strictly higher and stays unpublished until a cleared run exists.

Can PhylaXron FBD 14 be cleared?

No cleared run had been filmed as of 2026-09-20. Seol's attempt held rank-B pace to 077'659'891 before BREAKs sank the miss gauge to −12. The practical read: the final stretch, not the opening, is where your deck needs the survivability to absorb mistakes.

Will this page spoil the story?

No scenes, dialogue or endings appear in any frame — every image is a UI screen or gameplay field. The chart's existence and its semi-boss tier hint at late-game progress, so brand-new players may want to clear the story first.
