Reworked Kanna Culvert rotation (raw video, check DESC for rough timestamps and info)

Описание: _Fatal_
Up to you to decide how much time you want at the end for repressing haku and stuff, but one timing you can do is:
Proc fatal 5 seconds before pressing CV1 in waiting room (eg. 2:25 proc fatal, 2:20 hit CV1) and make sure to proc fatal like 2s after when you enter the boss room. Origin at ~11s left

_Cooldown Reductions_
-2 hat, -1 wings of fate, 6% merc cd reduction
Note: For every second or % missing, enter approx. that many seconds later on oni cd pre-entry pops (eg. no -1 wings enters at 29s remaining on oni, no -1 wings and only 5% merc enters 27-28s left on oni cd) -- although, atp you probably aren't tryharding culvert so don't even worry about it since the server lag requirement becomes heavier each second you don't have -cd for

You don't need to keep -2 hat on the entire time (can swap off after pressing CV3 in waiting room), but it helps with recasting oni/tengu and ab/call of unity

If you have ror4 i believe in you to figure it out

If you have -4 hat, you can enter 2s earlier, ror at the start with wof, then swap to -2 hat and regular cape. Figure that one out yourself if this applies, I'm too poor, not tryhard enough :(

_Sequences_
CV1
Akatsuki Blessing (10% Dmg)
Twilight Bloom (50 matt, 15% cdmg)
Unleash the Radiant Flame (if LV30 HEXA or close)
summon: Orochi, Oni, Tengu

CV2 (mainly just true name, need sequence for less animation time
True Name Revelation (summon amp)
Unleash the Radiant Flame (if LV0 HEXA or close)
Echo, Attack Speed Booster if needed

CV3
Call of Unity (13-39% dmg)
AB Link (60% dmg)
Princess Sakuno's Blessing (25% fd)
Haku

_Pre-Entry_
Make sure mana overload is on
Make sure familiars are out
Use consumable buffs and stuffs
Have Risk Taker on main hand, RoR on swap
Have Wings of Fate cape on with -1
Permanently keep -2 hat on during the culvert battle to help a bit with cast timings

Start (not entering yet)

1. Press Sequence CV1

2. Track Oni summon timer:
Oni 43s cd left, press True Name Revelation. If you have lv0 Hexa Radiant Flame, use that here (CV2 / just True Name Revelation).
Oni 33s cd left: Sakuno's Blessing (+25% fd), Call of Unity (+39% dmg), AB link (+60% dmg), Haku (summon extension)

3. Oni 30s cd left: Enter culvert
Unequip wings of fate some time before boss spawns

_In Culvert_

Press sense procs as you get them, otherwise toilet paper throw is default move

Stage 1-3: Just toilet paper throw, no need to bother with sense if you one shot them
~116s Stage 4: Oni spin
RT + Gene when stage 4 dies

~115s
*If orochi or oni resonate on stage 5, prioritize using that skill use
Use orochi execute on stage 5 and tengu, oni pulv if you didn't kill it yet

~113s
Use Heart-Wreck Talisman when stage 5 dies

Use oni pulv on stage 6, use any last second sense procs you get with orochi prio. Make sure to not miss oni sense procs as well but prio orochi since that thing is just server lagging atp. If you server lag enough, then haku pops here instead of stage 5 C:

~106s Bind boss and dodge pillars to preserve Risk Taker

98s resummon Oni/Tengu off cd (Sequence CV1 off cooldown)
Use any oni, tengu, orochi skills as they come up
Use the 3rd job iframe (Barrier: Curse Ward) to dodge at least one culvert boss attack to preserve risk taker even more
When Risk Taker expires or to dodge an attack, start chucking in the Ascent skill usages
At some point, find a time to swap to Weapon Jump -- *Note:* You can still user [Order] skills and Heart-Wreck Talisman (if you forgot) when trying to swap since they don't put you in combat. Do this before 60s on culvert boss

76s AB, Call of Unity (Sequence CV2 off cooldown)
some time after 60s, use Heart-Wreck Talisman to re-apply debuff

45-55s WJ4/5
52s Will, Seren

41s Akatsuki Blessing, Twilight Bloom, Oni, Tengu, Orochi, Unleash the Radiant Flame (if lv30 hexa) (Sequence CV1 off cooldown)
**DO NOT USE NATURAL OROCHI EXECUTE UNTIL 10x STACKS, ONLY USE FREE RESONATED OROCHI PROCS

32s or earlier: Use natural cd Orochi Execute (should be 10x stacks here, just use it though even if it's not)
31-35s swap to ror at some point when wj expires

31s True Name Revelation, Unleash the Radiant Flame (Sequence CV2 off cooldown)

21s Sakuno, Call of Unity, RoR, AB, Haku (Sequence CV3 off cooldown)
Use Spirit Tengu / Spirit Orochi skills
At some point, press origin
Press the natural cd Orochi Execute the moment it comes back up (1-2s left)

Note: Since HEXA Unleash the Radiant Flame has varying durations, you'll need to figure out where/when to pop it yourself. You can just group it with either the 30s duration skills if you're closer to lv0 or the summon sequence for convenience if you're closer to lv30

_Tips_
This rotation is basically:
If Oni/Orochi is up, press CV1
If Call of Unity up, press CV3
If True Name is up, press CV2
I recommend putting the above in your quick slot view so you can see their cd
