DefenselessIn-game tip

Increases damage taken while airborne. Increases more for Lightning Damage.

He's wide open in this state, so dump your hardest burst and your air combos here, since launching him stacks even more vulnerability.
Lightning carriers do extra work right now, and Holy hitters do too, so lean on whatever Lightning or Holy DPS you brought.

HardeningIn-game tip

Attack and Block Rate greatly increase periodically. The duration of this increase is reduced each time an incoming attack hits.

When his attack and block spike, don't try to out-trade it; just keep landing hits, since every connect chews down the buff's timer.
Steady, fast multi-hit pressure beats one big swing here, so favor rapid Holy attackers to strip the Hardening quickly rather than going for slow heavy hits.

OverloadIn-game tip

Completely filling the Daze Gauge while it's preparing for a powerful attack will inflict stun.

When he starts charging the room-wide blast, race the Daze Gauge to full before it fires; capping it mid-windup stuns him and cancels the whole detonation.
Save daze-heavy cooldowns for this moment so you can guarantee the stun, then immediately pile on Holy damage while he's locked down.

Moveset — the real numbers

Its AI decides when it uses what, so there is no fixed rotation to memorize — but every damage %, reach, duration and crowd control below is exact.

Attack	Damage (% of ATK)	Reach	Duration	Control
Dark detonationThe big windup nuke that blankets almost the whole arena. This is the one you want to stuff by filling the Daze Gauge before it goes off.	—	25m	5.07s	AirBorne
Endless onslaughtA long, rolling barrage of small circles that pins you in place. Keep moving and don't try to facetank the whole sequence.	—	2m	11.83s	—
Rapid flurryA flurry of quick pulses capped by a bigger hit, all with knock-up. Break line of sight by repositioning between the small pulses.	—	3m	6.98s	AirBorne
Spinning rampageA spin of tight, hard-hitting circles around the boss. Stay at mid-range so the tight radius whiffs.	—	2.5m	4.17s	AirBorne
Dark beamA straight multi-hit beam down a narrow lane. Strafe sideways out of the line and it does nothing.	—	5m	3.87s	—
Lunging jabsA short string of forward line jabs. Quick dodges to the flank slip past the whole set.	—	2m	3.16s	—
Double slamA two-hit ground combo, both with knock-up. Wait out the first slam before you re-engage so you don't eat the second.	—	4m	3.83s	AirBorne
Cleaving coneHis heaviest basic swing in a wide frontal cone. Get behind or off to the side rather than backing straight up.	—	6m	2.36s	—
Crushing finisherA combo that lands two taps then a heavy slam with knock-up. The big hit is the one to dodge; the taps are chip.	—	4m	7.1s	AirBorne
Mixed comboA three-part combo that mixes a line then two overlapping circles. Roll through the line, then clear the circle stack.	—	5m	7s	AirBorne
Entrance shockwaveAn opening burst with knock-up as he lands. Don't crowd the center on the pull or you start the fight floored.	—	50m	14.3s	AirBorne

The phase descriptions are the official in-game boss tips; the tactical bullet points are our advice. Every damage value, reach, duration and crowd-control effect in the moveset is the boss's real in-game value. Attack names are descriptive labels.
