| Type | Zonai block miniboss guarding Sage’s Wills, Old Maps and chests (sky and Depths) |
|---|---|
| Variants | Flux Construct I, II and III |
| HP | 360 (I; 200 on the Great Sky Island), 720 (II), 1,080 (III) |
| Attack | 20 (I), 40 (II), 55 (III) |
| Weak point | The glowing core cube among its blocks |
| Key drops | Zonai Charge, Large Zonai Charge, Flux Construct Core, a reward chest |
A Flux Construct is a mass of Zonai blocks that rearranges itself into fists and walls. The only part that matters is the core: the cube with a bright green face. Keep hitting that cube and the pile falls apart.
Flux Construct Variants
| Variant | HP | Attack | Core fuse power (sword) | Charges dropped |
|---|---|---|---|---|
| I | 360 (200 on the Great Sky Island) | 20 | 10 | Zonai Charge x6-8 |
| II | 720 | 40 | 20 | Zonai Charge x7-9, Large Zonai Charge (20%) |
| III | 1,080 | 55 | 32 | Zonai Charge x8-10, Large Zonai Charge (60%), Big Battery (3%) |
The bigger the number, the more blocks it throws at you and the harder they hit; the plan stays the same.
Where to Find Flux Constructs
| Variant | Locations |
|---|---|
| I | Great Sky Island (the first fight, guardian of the island); West Hebra Sky Archipelago; sky islands above Typhlo Ruins; the Depths below Lookout Landing |
| II | Sky island at (-1327, -1567, 801); Depths below Lindor’s Brow, Typhlo Ruins and Eldin Canyon |
| III | Sky island at (-2270, -424, 914); Depths of Lindor’s Brow and Raspro Pass; North Lomei Depths Labyrinth; the sky above Lake Hylia (Sage’s Will); the last terminal at (-1795, -3579, -539) |
A Flux Construct guards a Sage’s Will on most sky islands, and each one guards a chest with a key or a weapon on the Depths islands.
How to Beat a Flux Construct
Find the core
The core is the glowing cube among the stone blocks, often framed by a green symbol. It floats up and drifts around while the blocks move. Do not waste time on the other blocks.


Break the core
Use arrows or thrown Bomb Flowers on the core while it is exposed. Dodge sideways when the fists drop, hit the core in the gap, and repeat. For Flux Construct III, keep moving between hits since its bigger blocks fill the whole arena.



Collect the Zonai loot
When the core breaks the pile collapses into Zonai Charges and Large Charges. Pick them up, and open the reward chest that appears where it stood.


Skipping and tricks
- Most Flux Constructs that guard a Sage’s Will keep the chest on a block you can pick up with Ultrahand: grab the chest, carry it off and open it elsewhere. The exception is the West Hebra Sky Archipelago one, where King Gleeok has to be defeated first.
- Recall on a block, or an arrow into the core, halts it for a few seconds; look for the cube with the glowing eye and hit that one.
- Each Sage’s Will you collect (there are 20, four per upgrade at a Goddess Statue) strengthens one Sage’s ability.
Drops
| Flux Construct | Drops |
|---|---|
| I | Zonai Charge x6-8 (100%), Flux Construct I Core (100%) |
| II | Zonai Charge x7-9, Large Zonai Charge x2-3 (20%), Flux Construct II Core |
| III | Zonai Charge x8-10, Large Zonai Charge x2-3 (60%), Big Battery (3%), Flux Construct III Core |
The core fuses to a weapon for extra attack power (more with each tier), and the Zonai Charges refill your devices and vehicles.
Best Farming Spot
Flux Construct III in the Depths gives the best charge payout, and the Depths sites below Lindor’s Brow and Raspro Pass are reliable repeat fights.
