PhylaXron — FBD 14 Dive, Frame by Frame
TAISHI · MIN 6 · EVO 9 · ULT 12 · FBD 14 · DIVE FAILED
A frame-by-frame read of Seol's FBD 14 dive into Taishi's PhylaXron — the CONNECT pairing against FELL, the triple wide walls, the yellow flick rain and the violet zigzag — ending where this run ends: a DIVE FAILED banner at 086'571'627, with the rank B result card that shows exactly what a top-tier miss costs.
The run at a glance
- ▸Single source: Seol's FBD 14 dive into PhylaXron (uploaded 2026-09-13) — the catalog's top-tier chart for Taishi's Arc 4 song, played as a CONNECT dive pairing NIA against FELL at SPEED 4.80, with the capture itself reading Assist Mode Enabled on the detail and CONNECT screens.
- ▸The result card: SCORE 086'571'627, rank B, MAX LINK 123, HIGH SCORE —, DIFFERENCE +086'571'627 — the arithmetic checks to the digit: with no prior registration on the chart, the difference equals the run's own score, a first registration rather than a personal best.
- ▸The four judgement rows — EXACT 2437 + 323, NEAR 223, BREAK 334 — sum to 3,317. The catalog documents no FBD note split for PhylaXron (MIN/EVO/ULT only), so 3,317 stands as the only count in the room; a hover popup reads NEAR as EARLY 163 / LATE 60. MISS GAUGE -12: the gauge ran past empty.
- ▸The failure is on the card twice: the DIVE FAILED bar and MISS GAUGE -12. The last full-strength wall posts 084'805'129, breaks up by 085'627'767, and the score freezes at 086'571'627 with the combo watermark at 50 — MAX LINK 123 was the best mid-run chain, not the streak at death.
Source footage
One video backs every still below: Seol's PhylaXron FBD 14 dive (3:56, uploaded September 13, 2026) — a 2560x1440 60fps capture with the in-play panel itself reading FBD 14 next to SPEED 4.80. Deep links in each step jump to the matching moment.
The upload's automatic captions carry only the song's vocals — no narration — so every fact below is screen forensics cross-checked against the song catalog. The capture carries no camera and no channel watermark; one recorder-side overlay exists, a Discord friend-activity toast in the lower-right corner for roughly seconds 59-63, patched out of the violet-sail still alone with a delogo fill of 296x60 at x1300/y836 measured on the 1600-wide stills — every other still is untouched, and the video itself is untouched and linked in full. Deep-link seconds follow the decode-accurate timeline of the upload and can land a moment off; every still was verified individually.
The chart at a glance
CATALOG · V1.0.2CLevels and note counts below come from our song catalog (community wiki data, game version 1.0.2c) — the same source every guide on this site quotes. The catalog documents no FBD note split for this chart; the dashes in the FBD row are the catalog's silence, not an omission here.

PhylaXron's documented splits — MIN 1,400, EVO 1,817 and ULT 2,713 notes, that ULT row the largest documented split in the whole catalog. The FBD 14 row the capture plays has no documented split, so the result card's 3,317 judgements stand unopposed.

Read the song-detail screen
Before anything moves, the detail screen states the terms: a red 14 beside DIFFICULTY FORBIDDEN, HIGH SCORE — (a dash — nothing registered on this chart yet), the shattered-glass jacket crediting ILLUST 春星京芒, and the pairing widget reading NIA ↔ FELL over Assist Mode Enabled.

Set the terms: FBD 14 at SPEED 4.80
The CONNECT overlay pairs NIA against FELL with the Assist Mode Enabled plate between them, the highway waiting behind at 000'000'000; the in-play panel fixes the terms — PhylaXron, Taishi, FBD 14, SPEED 4.80.

The empty highway
Lane keys Shift, A, S, D, F, Space line the keystones at 000'000'000, the first violet triangle already descending the center — six lanes, one judgment line, and the whole chart still unread.

Opening: the full-width cyan panel
The chart announces itself with a full-width cyan panel under an EXACT row at 001'095'760 — a violet triangle hold riding the center as the first gold sparks fly at the keystones.

The curved violet sail
A tall violet sail curves down the middle of the highway at 016'220'992, gold bursts firing at the edges while the tag row reads EXACT, BREAK, EXACT, EARLY — the chart's first mixed verdicts.

The first triple wall
Violet left, cyan center, pink right: the first full-width wall arrives at 017'975'385 with a yellow flick wedge slashing across — the motif that will carry the rest of the chart.

Yellow flick wedge rain
At 025'942'183 a cluster of yellow flick wedges falls across the upper lanes over a five-across EXACT row — flick stamina check number one, with the combo watermark at 7.

The violet zigzag
A violet slab steps down the lanes in a zigzag at 027'610'291 while a wide pink beam holds the right side — the chart's signature shape, and the combo watermark reads 45.

The long wall — fourteen seconds wide
From 041'548'637 to 050'933'199 the highway runs wall to wall: violet, cyan and pink full-width beams with dense EXACT rows and the odd BREAK — the endurance trough where this dive's gauge quietly drains.

Where the run starts bleeding
At 074'530'385 the tag row reads EXACT, BREAK EXACT, BREAK, EXACT, EARLY NEAR, EXACT over gold debris — the stretch where FBD 14 starts collecting its cost in missed links.

The last wall, and the freeze
The final full-strength wall posts 084'805'129, breaks up by 085'627'767, thins at 086'401'338 — and the score freezes at 086'571'627 with a violet triangle unjudged at the line, combo watermark 50.

FAQ
FBD 14 · THE TOP TIERHow hard is PhylaXron FBD 14 in In Falsus?
It is PhylaXron's ceiling and the catalog's top tier: MIN 6, EVO 9, ULT 12, FBD 14. Five songs share the FBD 14 tier — Chronophobia, code:Leviathan, Hollow, PhylaXron and TACTOM — and the result card on this page shows what it costs in practice: 3,317 judgements, rank B, and a MISS GAUGE that ran past empty.
Is FBD 14 the highest difficulty in In Falsus?
Almost — it is the highest tier the catalog shares: five songs chart at FBD 14, and exactly one chart sits above it, the song '▓' at FBD 15. PhylaXron's FBD 14 is therefore top-tier play one step below the game's single hardest chart — the tier where this capture's dive failed.
Why are there two EXACT rows on the result card?
The game splits EXACT judgements into two tiers, and the card counts them separately: EXACT 2437 + 323 — the same convention as the Hollow and Things I Treasure cards on this site. Added to NEAR 223 and BREAK 334, the four rows sum to 3,317 judgements.
Why doesn't the 3,317 match a note count?
Because our catalog documents no FBD note split for PhylaXron — the table above dashes the FBD row while quoting MIN 1,400, EVO 1,817 and ULT 2,713 from the wiki, that ULT row the largest documented split in the catalog. The 3,317 is transcribed from the result card alone; the hover popup over NEAR reads EARLY 163 / LATE 60, which sums to 223.
Did the dive fail because of Assist Mode?
This page doesn't make that claim — it can't. The capture states Assist Mode Enabled on the detail and CONNECT screens, and it is quoted as shown; what the card states about the failure is MISS GAUGE -12, the gauge having run past empty, with the DIVE FAILED bar above it. What Assist Mode changed, if anything, is not written on any screen in the capture.
