Energy CasingIn-game tip

Using certain skills causes casings to drop from its shoulder. The casings can be destroyed, and the main body's Defense deceases slightly each time.

Lean on AoE and multi-hit kits to pop the shoulder casings the moment they drop — every casing you break chips its Defense, so your damage ramps the longer you keep them falling.
Save your hardest-hitting cooldowns for after a casing is destroyed, not before; you're fishing for that stacking Defense down.

Energy ReloadedIn-game tip

Once all shoulder casings are exhausted, reloading begins. After reloading, the Defense reduction effect on the main body is removed. If all 5 casings are destroyed before reloading is completed, 「Corrupted」 Guardian Golem enters dazed status, during which its defense greatly decreases.

Reloading is your win condition: race to destroy all 5 casings before the reload finishes to force the daze, then dump everything during the big Defense drop.
If you let it reload, you reset the Defense reduction — pre-stage your burst and a stun/interrupt so the fifth casing dies in time.

Cartridge CombustionIn-game tip

Damage taken greatly increases when casings are inflicted with a Fire debuff.

Bring a Fire user (or a Fire cover/coating) and tag the casings with the Fire debuff before you shatter them — the burning casings take massively increased damage, which is the fastest route to the daze.
Coordinate the Fire application with your casing burst windows so the debuff is live when you swing, not wasted between phases.

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
Core overloadThe big one. Huge arena-wide blast that stuns on hit — get out of the circle the instant it winds up, this is what wipes runs.	—	23.9m	10.5s	Stun
Rail barrageLong straight-line volley that reaches almost across the room, finishing with a heavier shot. Side-step off the line, don't try to outrun it.	—	41.4m	7.35s	Stagger
Double slamTwo stacked stagger hits, outer ring then inner. Wait out the first impact before you reposition or the second clips you.	—	7m	8.39s	Stagger
Triple crusherThree overlapping zones that knock down, stagger and knock up. Loaded with crowd control — keep a cleanse or stand clear of the cone.	—	9m	6.72s	Knockdown + Stagger + AirBorne
Launching strikeTight line hit that ends on a heavy knock-up. Easy to dodge sideways, brutal if it catches you airborne.	—	4.5m	5.47s	AirBorne
Empowered swingThe charged version of its line poke — big single hit with knockdown. The slow wind-up is your tell to roll through.	—	6m	6.18s	Knockdown
Ground poundWide point-blank slam that staggers. Comes out near and far, so don't assume range keeps you safe.	—	7m	3.83s	Stagger
Cleave comboQuick two-part swing, line then circle, ending in a stagger. Low damage but interrupts your combo if you get greedy.	—	3.5m	4.08s	Stagger
Frontal sweepShort cone jab in front of it. Stay off its facing and you skip this one entirely.	—	6m	3.48s	—
Step jabClose circle hit into a forward cone. Bait it, side-step, punish the recovery.	—	5.5m	4.87s	—

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.
