In Tears of the Kingdom‘s big first gameplay reveal trailer, there were quite a few shots that got everyone curious, but none quite like the shot of Link fighting a massive boss made of different cubes, looking like something straight out of Minecraft. This boss is a recurring one you’ll find on sky islands or the depths, and it gives some great rewards.
These are called Flux Constructs; they might be a difficult challenge for anyone looking to approach them like a typical boss since they expect you to think outside the box and use every ability to take them down.
However, you can take them on at any point in the game, and it’s far more manageable once you know the best way to take them on, which is what I will discuss in this Tears of the Kingdom Flux Construct guide.
Bottom Line Up Front
Flux Constructs are never found on Hyrule’s surface and are exclusive to the skies above and the depths below. Furthermore, they only spawn in one of 3 variants, getting more difficult the higher their number.
What are Flux Constructs?
There is barely any lore or mention of the Flux Constructs from characters within the game; they primarily exist independently. The only real piece of lore we have is the Hyrule Compendium description: “A construct composed of interconnected blocks, made by the Zonai with advanced techniques and magic.
This description shows they’re an advanced version of Zonai constructs, which usually come in forms such as Ranger, Captain, or Soldier constructs. These look incredibly different from the Flux constructs, so maybe the flux constructs were explicitly built to guard more important structures than the rest of the hostile constructs.
Either way, they’re Zonai-built contraptions, so you can use anything they drop with Zonai equipment to get the boost they have for synergy. It’s made of a bunch of blocks, all of which are moveable with Ultrahand, so it’s pretty good at fitting in with the other Zonai creations we’ve seen in Tears of the Kingdom.
Finding Flux Constructs
There are around 40 different places that these bosses can spawn. If you’re good at exploring the Sky Islands (a completely circular island is an obvious sign, you’ll find one) or the Depths (these have no clear tell but aren’t exactly uncommon), you’ll come across quite a few in your travels.
Flux Constructs have three different variations; Flux Construct I is the basic form, only providing a moderate reward. Flux Construct II is a bit more advanced and will take some extra firepower to beat. Finally, Flux Construct III is the most challenging variation, and I’d only recommend taking one on if you’re later in the game and want to challenge yourself.
Any given location will only spawn a single variation of Flux Construct, so if you fought a Flux Construct II somewhere, it would always respawn on a Blood Moon as a Flux Construct II, unlike most other enemies and minibosses that dynamically scale their difficulty with your progress. This means you could go for a hard one for a decent boost in the early game.
Here I’ve decided to mark three sky islands with a Flux Construct I (at 0472, -1514, 1439), a Flux Construct II (at 3003, -0245, 0917), and a Flux Construct III (at -2313, -0431, 0894). Again, I’d recommend only going for the later ones once you’ve progressed a decent way through the game, but you can feel free to go for them if you’re confident you can take them down.
Fighting Flux Constructs
Much like the game itself, the fight against Flux Constructs is incredibly creative and unconventional and requires far more critical thinking than the standard miniboss. If you go in and expect to be able to smack it with your sword a few times and dodge some punches, then you’ll be pretty shocked.
They’ll start in Man form or as a tower working like a lighthouse, immediately changing shape when they spot you. Taking your time and getting a good approach before fighting it would be best. To begin, try flying in and shooting a few bullet-time arrows at its weak glowing point.
You’ll be hitting the glowing cyan cube on these constructs that I’ll usually call their (somewhat obvious) weak spot. You need to hit this a few times in quick succession (or do some alternate method) to get it to break off and cause the Flux Construct to fall apart. This gives a chance for easy damage, then moves to a new form.
It will often make its weak point start glowing, as well as another cube on its body, indicating it will swap its weak point somewhere else. This can occasionally make the boss more difficult, but it is usually just random enough to where it’ll also switch to a more accessible place to hit; the higher-tier ones will swap more often.
The higher the number, the higher its health and damage. Other than that, it only attacks a bit more often, swaps its weak point around more often and has better rewards for being a higher tier. No new phases or forms are added for the higher tiers; they’re blatantly more powerful versions.
“Man” Form
The Flux Construct will rearrange its boxes into different shapes, which I’ll call forms. The one it’ll almost always start with is the humanoid Man Form, where it will mostly try to throw punches at you, stomp on you, and detach its boxes to use as projectiles hurdling your way.
The easiest way to counter this form is by running under the legs and shooting the glowing cube (which will always be its weak spot for every state), but this can occasionally be difficult due to it turning around and preventing you from getting your shots off, meaning you should only really try this if you have a clear shot.
Ascend is very useful here. I’d recommend running under the torso, but if you can get a clear shot underneath the arms or in the back, that works too. It’ll let you rise through the entire enemy, getting to the top of it and then wailing on it until it falls apart. You can get as much damage as needed as soon as it falls apart.
Ultrahand and Fuse can also be helpful here. With Ultrahand, you can try to pry off the glowing cube, making it immediately fall apart. And if you manage to fuse five cubes quickly, it’ll fall apart and be even easier to reach the weak spot, granted that you have five shields and melee weapons available for fusion.
Potentially one of the best ways is the simplest. Just climb up and hit the weak spot with a melee weapon. There isn’t much to this one other than the Flux Construct pausing for a minute to let you on but also trying to shake you off quickly after you climb up on it. Be fast, climb quickly, and hit hard.
Rubiks Cube Form
Occasionally, Flux Constructs will decide not to let you have fun anymore, switching to a 3x3x3 cube with the weak spot, thankfully on the outside, usually in the middle of one of the sides.
Unfortunately, this cube will roll towards you like a Tox Box in Mario Galaxy, eventually deciding to hover above you and slam the ground, doing way too much damage if it hits.
I recommend dragging out every cube you can get with Ultrahand. Unfortunately, it doesn’t tend to return to normal in this phase, instead opting to attempt manslaughter. Pull out about three cubes at a time, focus on dodging, then repeat until you’ve disassembled it. It’s dangerous, but it will usually turn out fine once you grab the weak spot.
One easy way to overcome this form (and many obstacles in life) is just by exploding it. If you have enough bomb flowers in your inventory, you can keep throwing them at the cube until it disassembles itself. This technically goes for just about any phase this boss has, but this is where it’s most effective since all the cubes are bunched up.
Fuse again works if you have five shields or weapons available, but it isn’t as easy to recommend since this phase usually doesn’t let you get too close. I’d recommend just going for one of the previous methods since Ultrahand is a far higher-range tool that is way more useful in this scenario.
Skyblock Form
Occasionally, the Flux Construct will decide to turn into a flat surface and levitate just out of Ascend distance. During this phase, it’ll send blocks flying toward you and do almost nothing else until you hit it and break it. I’m convinced this phase exists only to make you upset until you figure out the solution and then feel dumb after.
Essentially, you can avoid the block when it throws it at you, jump on it, recall it, then absolutely demolish it. So it’s not hard at all to clear this phase in just a few seconds as soon as you learn about this technique, but if you want to make it at least a little more interesting, there are a few other ways to go about it.
I personally kept trying to take the blocks with ultrahand, stack them up, climb up, and use Ascend. While this should work in theory, the flux construct will almost always take the blocks back before you can finish doing this, and you need at least two blocks to get enough height for Ascend to work, so it’s usually too difficult to do quickly.
Another way that actually works most of the time is the old reliable, just exploding it again. Bombs fused to arrows will almost always be enough to hit through the bottom layer of blocks and damage the weak spot, just two of them being enough to make it disassemble entirely and give you the ability to hit it properly.
The fastest way to get this done is by fusing a rocket to your shield, then saving it until you see the phase pop up. Then, you can use another shield for, well, shielding until the time comes, then switch to your rocket shield and use it to fly straight up, able to either shoot the weak point a ton or land and get in some damage.
The Rewards
What you get from finishing a fight with a Flux Construct varies between each construct difficulty and between the Sky Island and Depths variants, which is the only difference based on location. You can expect a unique reward from every different Sky Island construct, while the Depths ones generally give better rewards.
Almost all the Sky Island Flux Constructs come with a chest attached near their head, and you can either decide to Ultrahand it off and take it immediately or wait till it falls off naturally through the course of the fight. In addition, many of these chests contain a Sage’s Will, an extremely useful item I refuse to elaborate on for spoiler’s sake.
In terms of things the boss drops when it dies, on the Sky Islands, it’ll usually drop 5-8 regular Zonai charges (more are given the higher the level), a few orbs with Zonai devices in them, and a Flux Core which makes a great smashing weapon if you attach it to the end of a sword (which also gets more robust with each level).
The Zonai Charges can be used at the Zonai Dispensers on Sky Islands (and occasionally on the surface) to get a bunch of Zonai devices simultaneously. The Zonai Devices given from Flux Constructs are usually the super common ones, but the higher tier Flux Constructs have a slight chance of giving a Big Battery, the rarest device.
In the depths, on top of the Flux Core, Zonai Charges, and the Zonai Devices, you’ll additionally get Crystalized Charges. These are the things you need 300 of to upgrade your battery, which makes them extremely valuable and worth going for. It’s a difference between wanting to get Sage’s Wills or battery upgrades.

Tears of the Kingdom Flux Construct Guide: Conclusion
The Flux Constructs are always something I go out of my way to take on whenever I see them in Tears of the Kingdom, and that’s saying something considering I already have over a hundred Zonai Charges that I’m not using at this point. The fight is just entertaining and allows for many different ways to approach it.
I think the “man” phase is always the most fun part, given that the cube form can be an unfair death sentence, and the sky platform is exceptionally straightforward. Nevertheless, this boss keeps getting even more fun and exciting to fight as you try to shake it up and try a new method for your next battle.
