Miasma Priest daze thresholds are particularly steep for
Manato.
To get a good score, having good luck in the pre-1st stun attack patterns is mandatory. At least two multi-parriable strings from Miasma Priest, but ideally more, as the fast daze build from them helps in speeding up stuns.
Shoot for a first stun around the 02:20 mark. Even with multiple parries, at least one
Ju Fufu
EX Special is needed, which can make delaying the Miasma Shield phase with an early 2nd stun even harder. Try to sneak in a
Lucia
EX Special into
Basic 5 as soon as her Dream State ends, which should be happening very near the stun point.
Save Lucia's and Ju Fufu's
Ultimate for the out-of-stun period right after 1st stun ends to help build additional daze, and if possible, go into Manato's
Ultimate early and transition straight into
Basic Attacks, so that he can be landing the final hits as stun ends to further boost daze application.
If the daze bar is around 50, doing all parries (and the occasional
Assist Follow-Up between the final 4 hits) should build another 20 or so daze. Make sure to end on Ju Fufu so that she can go straight into an
Assist Follow-Up, then an
EX Special. Swap to Lucia for an
EX Special and
Basic 5 shortcut for even more Daze, then use Manato's own
EX Special for the rest.
At this point, the Might build on Ju Fufu should lead to a
Chain Attack, so swap to her for the trigger and go back to Manato for a standard combo.
It's likely that Dream State is running out again by the end of the 2nd stun, so refresh it and go into the Miasma Shield phase. Maximise as much daze as possible and don't hesitate on blowing Energy, as the Purify bonus will restore most of it.
Follow the same approach as the slashes before the 2nd stun to set-up for a fast 3rd. There likely won't be enough time to wait for a clock phase transition - even if this means lower Crit DMG on the combo, it's still preferrable to missing out on a 4th stun.
Once the 3rd stun is over, it's little more than praying for good luck with parriable strings to speed through to the 4th. Try using
Ultimates only duing clock phase transitions to not interrupt Miasma Priest out of any parriable attack strings, and squeeze in as much burst as possible before the timer runs out.
