[Maplestory SEA Aquila] Remaster / Redux Angelic Buster Sewers / Culvert

Tried to time my deathblow, but couldnt see the activation during the last burst. I think the timing is still abit off. Also tried to squeeze in 3 x Mascot. But the 3rd activation will not be in sync with the deathblow or the ROR. Not sure if it is worth it or should i just do 2 x Mascot and sync the second activation with the deathblow and ROR.

My rotation as follows:
-45s
Activate VCORE and charge Estacy

-10s
5s after second VCORE activation press FINAL CONTRACT

0s
Enter when FC at 20s

Countdown 3/2/1
Activate Goddess - Roll Dice - BOD - Planst Erda Shower

120s (Boss Spawn)
Spider - Solar - Fusion Trinity
At stage 5, Super Nova - Overdrive - Pretty Exaltation - TNC - Mascot

90s
In between just Fusion + Nova + Erda Shower (Don't cast nova if timer is below 60s, as it might interfere with ring swap.)

5Xs
Use Mascot for second activation

50s
bind + Ion (if no ion jump away)
swap to ror

At 40s
Activate goddess

At 30s
Nova + spotlight
FC + overdrive + exaltation
tnc + ring + (around 23-21s) origin

15s
(around 15s / vcore should activate around here as well)
Sparkle - Pantheon
TNC again if resets and 3rd mascot activation then hit till end.
