SONG GUIDE · ULT 10 FIRST CLEAR

cylin — ULT 10

ARC 2.5: EVERY MOMENT · KALSOER · FIRST CLEAR

cylin is kalsoer's contribution to the Arc 2.5: Every Moment chapter — cataloged at ULT 10 with an FBD 12 top tier, and built on sustained lanes rather than raw speed. This page walks the chart through a verified ULT 10 run that ends DIVE CLEARED at rank A, with the result screen's FIRST CLEAR tag in frame. The FBD 12 capture isn't verified yet, so every figure below describes the ULTIMATE 10 chart — the levels table still lists its FBD ceiling from the song database.

TL;DR

  • cylin is a kalsoer track in Arc 2.5: Every Moment (v1.0.2c): MIN 3, EVO 6, ULT 10, FBD 12 — one step below the game's documented FBD ceiling.
  • The ULT chart is built on sustain: 615 field plus 397 hold notes out of 1,498 total — roughly two thirds of cylin keeps lanes pressed while the rest of the hand travels.
  • Clearing tolerates mistakes: the source run counted 56 BREAKs against a MAX LINK of 313 and still finished DIVE CLEARED at rank A, with the FIRST CLEAR tag stamped in frame.
  • Every figure deep-links the creator's upload at the shown moment; the run's score 094'727'602 nearly doubled the account's previous best of 047'263'641.

SOURCE FOOTAGE

Every frame on this page comes from TrappyTheDemon's cylin ULT 10 upload (2:52): a full-screen chart capture with no handcam, no facecam and no commentary overlays. The recording runs song select, CONNECT intro, dive, DIVE CLEARED and result in one take, and the result screen stamps FIRST CLEAR — so the page can quote the whole run honestly.

Watch the cylin ULT 10 clear on YouTube

Two honesty notes: the uploader plays on a German-language client, so the two side lanes read "Umschalt" and "Leer" in the stills; and the walkthrough covers the ULTIMATE 10 chart only — cylin's FBD 12 level comes from the song database and has no verified capture on this page.

HOW THE CHART UNFOLDS

9 FRAMES · TRAPPYTHEDEMON CLEAR

Nine frames, one lesson each: how cylin opens, where its gold flicks land, what the twin field streams ask of your hands, and what the result screen can still teach after the banner. Timestamps quote the source video at the shown moment.

  1. 1

    Set the dive: cylin, ULTIMATE 10

    The song select screen confirms the target: cylin by kalsoer, DIFFICULTY ULTIMATE with the level 10 badge — and a HIGH SCORE slot already reading 047'263'641. That number is why this is framed as a first clear, not a sightread: the account had chased this chart before and failed. The run you are about to read nearly doubles the old mark.

    First notes down A S D F

    After the CONNECT intro the chart starts feeding notes down the A S D F lanes immediately, and by the 14-second mark the combo counter sits at 8 with the first strike burst blooming off the right side lane. cylin's ULT chart only carries 179 taps in total — the opening is a handshake, not the test.

    Gold flicks on the judgement line

    Around nineteen seconds in, a gold arrowhead note rides down to the line and the frame catches the golden strike effect mid-flash at combo 48. Flicks are cylin's second-biggest note group at 307 — when a gold shape reaches the line, the answer is a flick, not a tap.

    Twin field streams down the middle

    Half a minute deep, the chart shows its core idea: two cyan field streams running side by side across the center lanes while a purple diagonal joins from the left. Fields (615) plus holds (397) make up roughly two thirds of the chart — the skill being tested is sustained pressure, not speed bursts.

    A field note pinned, a side lane holding

    Around the 55-second mark a purple field note sits pinned on the line while a gold trace streaks the lane and the left side lane holds its own glowing segment. This is the cylin rhythm in one frame: something always held, something always travelling, and the EXACT chain ticking across the row.

    A breather with a hex-ring burst

    Deep into PHASE 4 the chart breathes: a single tap sits on the line, a cyan stream resolves on the left, and a gold hexagonal burst rings the lane mouth as it lands. cylin alternates pressure and relief like this all the way through — use the gaps to reset your hands, never your attention.

    The dual-beam finale

    The final stretch crosses a wide purple beam with a hot pink stream spanning the field at the same time. There is no chart after it — whatever the gauges have left belongs here, and the frame shows the run still keeping EXACTs at this density.

    DIVE CLEARED

    The banner lands — DIVE CLEARED — and moments later the CONNECTED encounter screen confirms the run from the other side. ULT 10 is demanding to full-combo but forgiving to clear: breaks cost combo and gauge, not the dive itself.

    Read the result screen

    The result confirms everything: rank A, score 094'727'602, MAX LINK 313, and judgement rows of 1300 + 96 EXACT, 46 NEAR and 56 BREAK — 1,498 judgments in total, exactly the catalog's ULT note count. The FIRST CLEAR tag sits on the IOTA row, and the DIFFERENCE readout +047'463'961 shows how far the run went past the old best.

CYLIN FAQ

SEARCH INTENT · ANSWERED

How do you unlock cylin in In Falsus?

cylin belongs to the Arc 2.5: Every Moment track group and is documented in the site's song database at game version 1.0.2c. The chapter's songs surface through the scenario as it advances — the Arc 2 guide covers how that family is structured, and the songs page carries the full catalog entry.

Is this guide for ULT 10 or FBD 12?

For ULT 10 — honestly. The verified footage on this page is a ULTIMATE 10 run stamped FIRST CLEAR on its result screen. cylin's FBD 12 chart is documented in the song database but has no verified capture here yet, so nothing above describes the FBD pattern itself.

How hard is cylin FBD 12?

Level 12 sits one step below the game's documented FBD ceiling of 13 (site song database, v1.0.2c). The ULT 10 chart already leans on holds and fields for about two thirds of its 1,498 notes — expect the same sustain ideas delivered at FBD density, not a different chart language.

What does ULT mean in In Falsus?

ULT is short for ULTIMATE, the third of the game's four difficulty tiers — MIN, EVO, ULT and FBD. The song select screen spells it out: cylin shows DIFFICULTY ULTIMATE with the level 10 badge. FBD (FORBIDDEN) sits above it as the fourth and hardest tier.

Who made cylin, and which arc is it in?

cylin is by kalsoer and belongs to Arc 2.5: Every Moment, documented at game version 1.0.2c. The site's Arc 2 guide covers the chapter family and its walkthrough, and the song database lists cylin's full level and notes breakdown.
