The Legend of Zelda: Tears of the Kingdom Flux Construct 2 boss is just one of three versions you’ll face while playing through the game. It’s the most common world boss, each more difficult than the last. The middle child of the bunch, this one takes more strategy to beat than the first but a little less than the third. If it’s the first you’ve fought, it can give you a run for your money. Our guide tells you how to beat Flux Construct 2 in TotK.

I’ve covered how to beat Flux Construct 1 and Flux Construct 3 already, and while some of the same strategies apply, there are some key differences that make these fights relatively unique.

TotK Flux Construct 3 Boss Fight Tips

To beat Flux Construct 2 in Tears of the Kingdom, you’ll need to damage the green-glowing core cube that helps make up its body. The difference from Flux Construct 1 is how the boss attacks, as well as its vastly increased damage output and health pool.

You’ll want at least seven or eight hearts, as well as some defense-increasing food, for the best chance of not getting one shot and needing to start the fight over again. Here’s how to upgrade your hearts if you don’t know how.

The easiest way to get the core loose is to use Ultrahand and pull it out of the body directly. You can also remove other non-core blocks, but whenever the boss re-forms from either an attack or a deconstructed state, all the cubes will return, forcing you to remove them again. Pulling out the core takes a little extra aim skill, but if you’re like me (very stubborn), a failure will still be a good teacher.

You can also deal enough damage to the core with arrows by other means to cause the TotK Flux Construct 2 boss to fall apart. No matter how you do it, when the core lies on the ground, you have about 10 seconds to hit it as much as possible until it reforms.

All Flux Construct 2 Attacks and Strategies in Tears of the Kingdom

Slam Rush

The boss’ opener, this attack separates into component blocks, and Flux Construct 2 rushes toward you. It slams its “hands” into the ground. Run to the side to avoid the damage, then rush back to the core as it recovers on the ground.

Hand Slam

At close- to mid-range, the boss will raise its right arm and slam down its “hand” in a slightly-less powerful attack than the Slam Rush. The windup is pretty long, and the arm stays embedded in the ground, so it’ll be easier to grab if the core is in that arm.


If Flux Construct 2 reforms with you near its feet, it will stomp three or four times, creating a small shockwave like the slam rush. As before, you can avoid the attack by running away. The Construct can’t move too quickly while stomping, so you can grab or attack the core freely if you keep your distance.


The TotK Flux Construct 2 flies into the sky, forming a platform that throws blocks at you for a frankly ridiculous amount of damage (this attack is really annoying). What’s more, it also has two variations:

  • One version shoots five of its blocks simultaneously.
  • The other version does so in a sequence.

The sequence attack is easy to dodge: just run to one side until it’s fired all five projectiles. The simultaneous attack is much more difficult to avoid, I found.

The simultaneous blocks have a minor but still noticeable amount of tracking. I died more times than I’d like to admit figuring out that you can dodge this attack the same way as the sequence. The key is that you’ll need to be much quicker about it. You could also run far enough away to let the blocks go around you. Either way, use Spring or Fan Zonain devices to get airborne and attack from above.


The Flux Construct 2 collects itself into a giant cube and slowly rolls toward you. This attack isn’t dangerous from a distance, but it will one-shot you up close. The boss also tends to roll much faster as a block, so you’ll need to do more to keep a distance between the two of you.

That’s everything you need to know about how to beat Flux Construct 2 in Tears of the Kingdom. It’s not the hardest fight in the game by any stretch, but if you go in unprepared, you’re liable to be flattened at least a few times.
