Cyaegha — FBD 12

• ▸Cyaegha is USAO's Arcaea crossover in the In Falsus track group — FBD 12, one step under the level-13 ceiling.
• ▸Its FBD chart carries 1,698 documented notes (489 taps / 494 holds / 375 field / 340 flicks); the difficulty is sustained overlap, not one impossible pattern.
• ▸Confirm your REFLECT loadout before the dive — encounter cards set the damage you can afford to trade across nearly 1,700 notes.
• ▸The source run cleared at 97,278,998 with full health deep into the final stretch — survival line first, score chasing after.

Frames come from たにし (Tanishy)'s Cyaegha run (2:49) — a DIVE CLEARED record at 97,278,998 whose video title lists the creator's own EX score of 98,411,476. This is a handcam view: the keyboard strip along the bottom edge is the creator's real hands, not part of the game UI. A burned-in Japanese spoiler warning covers the first eight seconds; every frame quoted here sits after it.

The final-gauge frame (2:32) and the CLEARED result (2:46) deep-link the creator's timestamps; the EX score in the title is the creator's best run, not the clear shown here.

Seven frames, one decision each: the loadout you bring, how the chart opens, the two pattern walls, the final gauge, and the result that ends the run.

1. 1

   Find the gate at FBD 12

   USAO's Cyaegha sits in the game's title track group and opens through normal story progression. On MUSIC PLAY its card reads FBD 12 with the sakura-blossom jacket carried over from the Arcaea version. If ULT 10 here feels stable, this is the chart to test whether the FORBIDDEN tier is within reach.

   

2. 2

   Confirm your REFLECT loadout

   Before the dive starts, the REFLECT encounter screen asks you to confirm your card loadout — five slots, and the last calibration point you get. Encounter cards decide your damage and color advantages, and at FBD density you will trade health constantly: bring the setup that keeps damage flowing, not the one that looks best on paper.

   

3. 3

   Opening: taps under a moving field

   The chart opens with keyboard taps on the floor lanes while purple field notes keep the mouse tracking from the first bar. Neither input is hard alone — the cost is running both at once. Settle your cursor hand during these opening bars, because the chorus assumes it never stopped moving.

   

4. 4

   Square holds under a curving laser

   The first real wall: a square purple hold runs while a laser bends across the field. One input has to stay pinned and steady while the other keeps moving — guess which hand is busier and route your fingers around it. Releasing the hold early is a BREAK, and BREAKs at FBD density are how health bars die.

   

5. 5

   The chorus pile-up

   The chorus overlaps tap and hold streams until the judgement line turns into a wall of green EXACT flashes — that green flow is the sign the run is healthy. Cyaegha's FBD chart documents 1,698 notes, and a large share of them land here; if a section is going to break you, it is this one.

   

6. 6

   Manage the final dive gauge

   The source run reaches the last stretch at full health with 98.4 million points already banked. That is the whole lesson of FBD 12: the clear was secured by protecting the gauge through the chorus, not by rescuing it at the end. Play the final bars the way you played the chorus — nothing heroic left to prove.

   

7. 7

   Reading a CLEARED result

   A surviving dive ends on the DIVE CLEARED banner, and the Encounter Result shows the run banked 97,278,998 of the 100,000,000 scale. Clears are survival-based — score above that is ranking territory. The creator's own video title records 98,411,476 for EX on this chart, which is the realistic next target after your first clear.
