Description

An upgraded Zonai Construct automaton found on mid-tier Sky Islands and in the Depths. Its cube-form rearrangements are faster than Flux Construct I, and the glowing core block is embedded deeper within the cube shell. Bring practiced Ultrahand aim and patience — the window to grab and pull the core is shorter than the introductory variant.

Weakness

Flux Construct II's primary weakness is Glowing core cube — harder to reach, pull with Ultrahand.

How to Beat Flux Construct II

1. Flux Construct II is the intermediate version with higher HP, faster attacks, and a better-hidden core.
2. It uses the same three forms as Flux Construct I but with significant upgrades to each.
3. Preparation: Bring strong fused weapons — the higher HP means you need to maximize each damage window.
4. Having Recall unlocked is very helpful for this variant.
5. Humanoid Form: The core cube is now embedded deeper within the construct's body, often surrounded by other cubes that block Ultrahand access.
6. You may need to hit the construct with melee attacks to knock loose some outer cubes before you can grab the core.
7. Alternatively, wait for it to perform its arm-swing attack — the motion sometimes shifts the cubes and exposes the core briefly.
8. The humanoid form is faster and hits harder than Flux Construct I, with a new spinning arm attack that covers a wide area.
9. Stay at medium range and dodge laterally.
10. Platform Form: The core is positioned more centrally on the platform, making it harder to reach even with Ascend.
11. After ascending through the platform, you may need to run across the surface to reach the core.
12. The platform form also drops cubes on you from height in this variant — watch for shadows on the ground and dodge them.
13. Use Recall on dropped cubes to ride them back up if you get knocked off.
14. Cube Form: The rolling cube is faster and more aggressive.
15. It actively tracks your position and changes direction mid-roll.
16. The core is embedded in a recessed face, making grab timing tighter.
17. The safest approach is to wait for the cube to pause before a slam attack, then quickly grab the core with Ultrahand during the windup.
18. Each core exposure window is slightly shorter than Flux Construct I — about four to six seconds — so use your strongest weapon to maximize damage.
19. Expect four to five core cycles to finish the fight.
