Flux Construct 2 Explained: The Strategy Most Players Get Wrong

You’re soaring through the South Hyrule Sky Archipelago, the wind whistling past Link’s ears, when you spot a massive, shifting pile of blocks on a distant circular platform. It looks like a pile of Zonai junk. Then it stands up. If you’ve played Tears of the Kingdom, you know exactly what’s happening. The boss bar appears, and suddenly you’re staring down a Flux Construct 2.

Honestly, these things can be a total nightmare if you try to fight them like a standard Hinox or Talus. You can't just run up and start swinging. Well, you can, but you’ll probably get flattened by a giant blocky fist or turned into a pancake by its "rolling cube" phase.

The Flux Construct 2 is the middle-child of the Construct family, and it’s arguably where the difficulty spike really hits. It has way more health than the Level 1 version and a few nasty tricks that can catch you off guard if you aren't ready to use Link’s new abilities in ways the game doesn't explicitly tell you.

Why Ultrahand is Actually Your Best Weapon

Most people think of Ultrahand as a building tool for goofy vehicles or bridges. Against a Flux Construct 2, it’s a surgical instrument. You aren't trying to hit the whole boss. You’re looking for that one specific cube—the "core"—that glows with a distinct green light.

Here’s the thing: you can actually yank the core right out of its body.

When the construct is in its humanoid form, it’ll try to smash you. Don't panic. Pull up Ultrahand, target that glowing core, and wiggle the right stick. If you can't reach the core because it's hidden behind other blocks, just start ripping the other blocks off. Once you pull out enough pieces, the whole thing just... collapses. It’s hilarious to watch this ancient war machine fall apart like a bucket of LEGOs.

The "UFO" Phase and How Not to Get Frustrated

Eventually, the Flux Construct 2 is going to get tired of your nonsense and turn into a flat, hovering platform high in the air. This is the part that usually kills the momentum of the fight. It starts lobbing blocks at you, and if you’re standing there with a sword, you’re basically a sitting duck.

You’ve got a few ways to handle this:

1. Recall is your best friend. This is the move most people forget. Wait for the boss to throw five blocks at you. Stand near one, let it hit the ground, then jump on top of it and hit Recall. You’ll ride that block like an elevator straight up to the main body.
2. Ascend. If the platform is hovering low enough, you can literally swim through the bottom of the boss and pop out right next to the core.
3. Bomb Arrows. If you’re feeling lazy and have the resources, two well-placed bomb arrows will usually force the construct to break apart and fall to the ground.

Better Loot: The Flux Construct 2 Core

The real reason you’re hunting these things isn't just for the Zonai Charges or the capsules. It’s for the Flux Construct 2 Core.

Unlike most monster parts, you can’t put this core in your inventory. It’s a physical object that stays on the ground. You have to fuse it to a weapon immediately. This core adds a massive +20 attack power to whatever you're carrying. If you fuse it to a Zonai weapon (like a Mighty Zonaite Sword), you get a hidden resonance bonus that makes it even deadlier.

It’s basically a high-tier hammer. It’s perfect for smashing ore deposits, breaking the armor off of armored Bokoblins, or just clobbering the next Construct you find.

Where to Find Them Without Searching for Hours

If you’re looking to farm these for parts, you won't find them just wandering around Central Hyrule. They like high-altitude real estate and the dark, creepy corners of the world.

• The Sky Islands: Check the South Hyrule Sky Archipelago or the North Necluda Sky Archipelago. Look for the large, circular arenas on your map.
• The Depths: There are several lurking near abandoned mines. Specifically, check the areas around the Gerudo Canyon Mine or the Abandoned Hebra Mine.

Be careful in the Depths, though. A Flux Construct 2 down there deals Gloom damage, which means every hit isn't just taking away hearts—it’s locking them. If you’re going into a Depths fight, bring some Sunny Fried Greens or whatever "anti-gloom" meal you prefer.

Pro Strategy: The "Bullet Time" Cheese

If you want to feel like a total pro, use a Wing shield or just jump off a small ledge to trigger bullet time with your bow. While time is slowed, you can easily pick out the core and pepper it with arrows.

One thing most players get wrong is staying too close. The Flux Construct 2 has a teleport smash. If you see it vanish, start sprinting immediately. It’s about to appear right above your head and try to turn Link into a post-it note.

Actionable Next Steps for Your Next Fight

1. Prep your Ultrahand: Ensure you're comfortable targeting moving objects. It’s the fastest way to end the fight.
2. Check your inventory: Do you have a spare weapon slot? You can't pocket the core reward, so make sure you have a base weapon (like a Claymore or a sturdy stick) ready for fusion.
3. Use the environment: If there's a nearby ledge or a Zonai spring, use it to get height. Attacking from above is almost always safer than fighting at its feet.
4. Don't ignore the blocks: Even if you can't see the core, ripping off random blocks weakens its attacks. A Construct with only three "fingers" hits a lot less hard than one with a full hand.
