Enigma — FBD 13
ARC 2: A PAST BEST UNTOLD · SANMAL · VERIFIED FRAME BY FRAME
Enigma is sanmal's contribution to Arc 2: A Past Best Untold, cataloged at ULT 11 with an FBD 13 ceiling — the game's 8-key top tier. This page walks the Forbidden chart itself through a verified chart view, frame by frame, from the song select to the result screen. The source attempt ends DIVE FAILED, and that failure stays in: the result screen is the clearest record anywhere of what actually kills an FBD dive.
TL;DR
- ▸Enigma is a sanmal track in Arc 2: A Past Best Untold (v1.0.2c): MIN 4, EVO 7, ULT 11, FBD 13 — and the in-game difficulty row maps that ladder to 4-key, 5-key, 6-key and 8-key layouts.
- ▸The chart opens with a pentagon house beam riding a pink fan, escalates to screen-wide translucent fans, then spends its middle doubling pink beams against purple counters.
- ▸The source sightread ends DIVE FAILED at rank D — 129 EXACT against 2,040 BREAK, MISS GAUGE -15, ENCOUNTER RESULT 6,400 FAILED — a clean look at how deck strength, not just chart skill, gates FBD dives.
- ▸Every figure deep-links Kyrosol's upload at the shown moment; Hodor1355's EX+ clear (99,333,515, title-stated) is name-checked as a reference score.
SOURCE FOOTAGE
Every frame on this page comes from Kyrosol's Enigma FBD 13 chart view (3:13): a full-screen playfield capture with no handcam, no facecam and no commentary overlay — the auto-captions hold four stray words, so nothing here is quoted from commentary. The upload records one continuous FBD attempt: song select, song detail, dive, DIVE FAILED, encounter result.
For a cleared reference run, Hodor1355's EX+ upload (score 99,333,515 as stated in its title) plays the same chart to the end — it is name-checked rather than framed because its capture carries a hand camera. The upload is VFR, so deep links can land a second or two off; every still on this page was verified individually.

Set the dive: Enigma, FBD 13
The song select lines the target up: Enigma's card carries the 13 badge under Arc 2's 'A Past Best Untold' banner, and the difficulty row spells the tier ladder out — 4-key MIN 4, 5-key EVO 7, 6-key ULT 11, 8-key FBD 13, with the FBD column lit. The CONNECT strip at the bottom shows what rides along: the Path Without Ambition encounter.

The song detail confirms FORBIDDEN 13
One screen later the badge is unambiguous: DIFFICULTY FORBIDDEN, level 13, over the jacket art. The CONNECT panel on the right pairs the dive with its encounter and the deck stats behind it — 3,100 and 3,200 on this loadout — the other half of what this attempt is about.

The opening: a house beam over a pink fan
The first seconds already stack shapes: a pentagon 'house' beam drops down the center lane while a pink fan spreads beneath it across the A S D F lanes. The sightread is bleeding from the start — the frame catches a NEAR at the line with the combo still in single digits.

A screen-wide fan rides the spark line
Inside the first minute the chart goes full width: a translucent purple fan spans the whole highway, its base dragging a white spark stream along the judgement line. Width, not speed, is the read — the fan eats your view while the lanes underneath stay busy.

Twin pink beams against a purple counter
The mid-chart's signature: two thick pink beams sweep the right-center lanes while a purple beam leans in from the left edge. The run's score has stalled by here — the pattern is readable, but this attempt is mostly answering it with BREAKs.

Cyan hold lanes under pink diagonals
Holds arrive as bright cyan ribbons: one runs the S D lanes while a pink beam cuts diagonally across D F, a yellow wedge marking its tail. The hands have to commit to the hold and let the beam cross — chasing the cross is how the combo counter dies.

The late zigzag down the D lane
In the final stretch a thick white-purple beam snakes in from the top, cuts across to the left, then drops straight down the D lane to the line. It is the last distinct shape the chart shows before it runs out of road.

DIVE FAILED — then CONNECT FAILED
Two banners close the run: DIVE FAILED lands at 2:57 with the score frozen at 005'947'571, and CONNECT FAILED follows on the still-lit playfield. The pair is the tell — this dive did not end at the chart's last note; it was lost alongside the encounter riding with it.

Read the result: what killed the dive
The DIVE RESULT screen is the lesson: rank D, MAX LINK 2, 129 EXACT against 2,040 BREAK, MISS GAUGE at -15 — and ENCOUNTER RESULT 6,400, FAILED. The game's own verdict, shown right after: this card loadout was not strong enough for the Connect Encounter. Enigma's FBD gate is deck craft as much as hands.

ENIGMA FAQ
SEARCH INTENT · ANSWEREDHow hard is Enigma FBD 13 in In Falsus?
FBD 13 is the game's top documented tier. The song select's difficulty row reads 4-key MIN 4, 5-key EVO 7, 6-key ULT 11 and 8-key FBD 13 (site song database, v1.0.2c), and the chart view on this page shows what that means in practice — full-width fans inside the first minute and twin-beam crossings through the mid-chart.
Is this a real FBD 13 guide or demo footage?
Real FBD 13. The source video is a chart view of the Forbidden chart itself — the song detail screen shows DIFFICULTY FORBIDDEN 13 before the dive starts. The run is a single continuous attempt and it ends DIVE FAILED, so the pattern coverage is complete and the fail state is documented, but no clear is claimed.
Why did the dive fail — the chart or the deck?
The deck. The result screen ends at ENCOUNTER RESULT 6,400 FAILED — rank D, 129 EXACT against 2,040 BREAK, MISS GAUGE -15 — and the game's own message says this card loadout was not strong enough for the Connect Encounter. FBD dives in In Falsus are gated by card craft as much as by chart skill.
Who made Enigma, and which arc is it in?
Enigma is by sanmal and belongs to Arc 2: A Past Best Untold, documented at game version 1.0.2c. The chapter's full track group and unlock path are covered in the site's Arc 2 guide.
What does FBD mean in In Falsus?
FBD stands for FORBIDDEN, the fourth and hardest difficulty above MIN, EVO and ULT. Enigma's song detail screen spells it out — DIFFICULTY FORBIDDEN with the 13 badge — and the song select maps FBD to the 8-key lane layout.
