The run can be split into 3 the lead up to each of the stuns:
- Opener & 1st Stun
- Miasmic Blades, Totem, Miasmic Shield & 2nd Stun
- Shieldbearers & 3rd Stun
The most critical period for this rotation is the lead-up to the 1st stun, as it is heavily dependent on good RNG to get the most damage out (although the 3rd stun can be difficult too).
Opener & 1st Stun
The goal here is to build enough Steel Charge to do 2
Enhanced Basic Attacks (EBAs)
Basic Attack: Falling Petals - Downfall before the 1st stun, and then getting it back up a third time to execute a full combo.
What makes this so RNG is that you don't want to just build gauge, you also want to parry enough times to max out Adjudication stacks provided on
Defensive Assists.
With 2 points being used for every parry on all 3 agents in this team, that means that without getting the spin attack from the Defiler, it is impossible to get more than 3 Adjudication stacks before the 1st stun.
This itself is already annoying, but then another issues arises where even if you do build enough stacks, you may end up stunning too fast to build up Steel Charge after the 2nd
EBA use.
Not to mention that with only 30 seconds in duration, you will want to refresh the buff shortly before the stun begins, as otherwise Adjudication stacks may fall off midway through your burst.
That means it's very difficult to have a clear route or script for this section. Try to parry the first and last hits of the spin attack and
Dodge Counter the rest so as to not waste time (and build excessive Daze) with multiple
Defensive Assists.
Miasmic Blades, Totem, Miasmic Shield & 2nd Stun
After the 1st stun things are more or less fully scripted. The Defiler will go into Miasmic Blades - which ideally should be parried 3 times for maximum Decibel generation - then activate her Miasma Shield and spawn the Totem that must be destroyed. Try to sneak in one more
EBA before the phase transition.
Since Miasma Shield breaks restore energy, it's good to use
Seed's
EX Special Attack: Raining Iron Petals after the 1st stun to empty out resources and fit in one more
EBA before The Defiler goes invulnerable.
When the Totem spawns, it's a good opportunity to swap to
Trigger and restore Purge - if maxed at this point it should last enough for the rest of the fight.
It's worth nothing that you should not use
Trigger's
Ultimate: Underworld Requiem out-of-stun to build Daze. Doing so may either lead to a stun before the Miasma Shield goes up (which you want to avoid, as the lack of resources make it not worthwhile) - and even if this does not occur, it builds too much Daze which will cause a problem after the Totem breaks.
This is because after The Defiler is once again targetable, she will do a series of 6 parriable attacks. Even if you use an
Assist Follow-up, it will not lock a character out of being selected, so make sure to go into one every single time on Seed to recoup Steel Charge.
Ideally you want to alternate like so:
S-Anby -> Seed -> S-Anby -> Seed -> S-Anby -> Seed
Do
Assist Follow-ups on
Soldier 0 - Anby too, but not so much that it will cause the Miasmic Shield to break early. If it does happen, try to at least end on Seed.
For the final parry - whichever one it is - you will want to go into
EX Special Attack: Raining Iron Petals right after to refresh
Dawn's Bloom and build the remaining Steel Charge. If Daze is too high, you can skip the final Assist Follow-up and just dodge counter into
EX Special Attack: Raining Iron Petals instead to make sure that the "Punch"
Basic Attack: Falling Petals - Slaughter initiates the stun.
If you've done everything correctly, you should have enough Decibels to use both Seed's and S-Anby's
Ultimates.
Miasmic Troopers & 3rd Stun
After the stun ends, The Defiler will go invulnerable and summon Shieldbearers (Miasmic Troopers) for 4 consecutive parries. Here you will want to feed every single parry to Seed, as otherwise she is unlikely to have enough Decibels in time for the final stun.
When all parries are complete, there should be enough time to fit one or two more
EBAs and then build enough Steel Charge for a full stun combo. Depending on how ahead or behind in Daze you are, either use Trigger's
Ultimate: Underworld Requiem to speed through to stun or reserve it for in-stun burst.
Now, doing a full set of parries will automatically generate 6 Adjudication stacks, so only 1 parry is needed to refresh it before the final stun. In the linked video however, 0 stacks are generated (as
Defensive Assists were not being done to Defiler), which meant a spin was needed to max out stacks.
If the final stun came early, use the little out-of-stun time left to fit in one more
EBA or burst down with S-Anby.
