Vesper — ULT 10

ARC 3: HEAVEN'S CHAINS · DUSTVOXX · FIRST-ATTEMPT CLEAR

Vesper is one of the eight Arc 3: Heaven's Chains tracks — Dustvoxx's contribution to the chapter, cataloged at ULT 10 with an FBD 13 top tier. This page walks the chart through a verified first-attempt ULT 10 sightread that ends DIVE CLEARED at rank A. The FBD 13 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

  • Vesper is a Dustvoxx track in Arc 3: Heaven's Chains (v1.0.2c): MIN 3, EVO 6, ULT 10, FBD 13 — one of six songs at the game's highest documented level.
  • The ULT 10 chart feeds taps down the A S D F lanes from the first bar, and its first split — hold beam left, sweep right — arrives inside the song's first ten seconds.
  • Clearing tolerates mistakes: the source sightread counted 46 BREAKs against a MAX LINK of 318 and still finished DIVE CLEARED at rank A.
  • Every figure deep-links the creator's upload at the shown moment; the run's final score, 094'778'984, is readable on the result screen.

SOURCE FOOTAGE

Every frame on this page comes from TrappyTheDemon's Vesper ULT 10 sightread (2:52): a full-screen chart capture with no handcam, no facecam and no commentary overlays. The upload records one continuous first attempt — song detail, dive, DIVE CLEARED, result — so the page can quote the whole run honestly.

The source video is VFR (variable frame rate), so deep-link seconds can land a second or two off the exact frame — the stills on this page were verified one by one against the upload.

HOW TO READ THE CHART

8 FRAMES · TRAPPYTHEDEMON SIGHTREAD

Eight frames, one lesson each: how the chart opens, where it splits your hands, where it goes widest, and what a first attempt can still get away with. Timestamps quote the source video at the shown moment.

  1. 1

    Set the dive: Vesper, ULTIMATE 10

    The song detail screen confirms the target before the dive: Vesper by Dustvoxx, difficulty ULTIMATE 10, with the HIGH SCORE slot still empty on this account. The connector card on the right shows which deck character rides along — Vesper sits in Arc 3: Heaven's Chains, so it appears here once the scenario has unlocked the chapter's tracks.

    Taps from the first bar

    No warm-up: the ULT 10 chart starts feeding taps down the A S D F lanes immediately, and the combo counter is already in the thirties a couple of seconds in. Read the lanes early rather than reacting at the judgement line.

    The first split: hold left, sweep right

    Inside the song's first ten seconds the chart asks for two things at once — a purple hold beam pinning the left lanes while a red beam sweeps in from the right side. It is the pattern the rest of the chart keeps returning to: one hand holds, the other travels.

    A wide fan over tap streams

    Mid-chart, a purple fan spreads across several lanes at once while the tap streams and the hex-shaped hold sparks continue underneath. The fan is wide but not fast — the risk is letting the streams degrade while you track it.

    Fan beam plus yellow wedge

    Around the song's midpoint the chart stacks its widest read yet: a fan-shaped beam and a yellow wedge landing on the judgement line together. The sightread run's combo had already taken damage by here — the shape is readable, but only if the earlier splits left a hand free.

    The screen-wide finale

    The final seconds throw a purple beam across every lane at once. The frame catches a NEAR inside it — the window is tight even on a clear in progress. Whatever is left in the tank goes here; there is no chart after it.

    DIVE CLEARED on the first attempt

    The banner lands without a retry: the sightread run cleared with the MISS GAUGE readout still visible at 15. 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 the picture: rank A, score 094'778'984, MAX LINK 318, and the judgement rows — 1119 + 76 EXACT, 42 NEAR, 46 BREAK. A first attempt with 46 breaks still clears at A, which tells you where the real grading pressure sits: full-combo runs, not survival.

VESPER FAQ

SEARCH INTENT · ANSWERED

How do you unlock Vesper in In Falsus?

Vesper belongs to the Arc 3: Heaven's Chains chapter, and its tracks unlock through the scenario — advance Act 3 and the chapter's songs join the catalog as story nodes clear. There is no separate purchase.

Is this guide for ULT 10 or FBD 13?

For ULT 10 — honestly. The verified footage on this page is a first-attempt ULTIMATE 10 sightread. Vesper's FBD 13 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 Vesper FBD 13?

Level 13 is the highest documented FBD level in the game, and Vesper is one of six songs sitting at that ceiling (site song database, v1.0.2c). Expect the same split-hold and sweep ideas as the ULT chart, delivered at FBD density.

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 detail screen spells it out: Vesper shows DIFFICULTY ULTIMATE with the level 10 badge. FBD (FORBIDDEN) sits above it as the fourth and hardest tier.

Who made Vesper, and which arc is it in?

Vesper is by Dustvoxx and belongs to Arc 3: Heaven's Chains, documented at game version 1.0.2c. The chapter's full track group and walkthrough are covered in the site's Arc 3 guide.
