Quick Links
There are enemies everywhere in The Legend of Zelda: Tears of the Kingdom, both below you, around you, and above you. If you venture into the sky to explore the game's new Sky Islands, you are sure to find a few enemies and bosses that want to take you out.
The Flux Construct II is one such boss that you will find among the game's Sky Islands, and it packs a mean punch. Much like its predecessor, it is composed of blocks, with one weak point that you need to target. However, unlike the first iteration, this one has a few new moves that you need to counter.
Updated by Shane Black on August 2, 2023: This guide was updated to include the locations of the Flux Construct 2 that can be found in The Depths underneath Hyrule, as well as mentioning some bows that can help in these fights since bows are a huge part of the strategy. It also added more links to relevant guides and articles to provide more information.

Best Weapons To Use
While just about any weapon can be used for this fight (though the less-powerful ones will certainly prolong the fight), there are always a handful of weapons that you can use to give yourself the best advantage. This comes down to their damage output, and they're all what you would think of as the best weapons in the game
- Fierce Deity Sword
- Gerudo Claymore
- Lightscale Trident
- Master Sword
- Royal Guard’s Claymore
- Scimitar of the Seven
All of these weapons will give you the most damage, especially when using Fusion to boost their numbers.
You will also want to bring a good bow to the fight since you will be using it frequently to hit the weak spot while it is in any of its formations. Here are the best bows to take with you for the fight:
- Dusk Bow
- Steel Lizal Bow
- Great Eagle Bow
- Royal Guard's Bow
- Savage Lynel Bow
The First Phase
When you first approach the Flux Construct II, you need to identify which of its blocks is the weak point that you need to be targeting. You will know which block this is as it has a soft blueish, greenish glow to it. It will be a part of its larger body and may be hidden behind another block. Move around until you can find it, and get ready to attack.
The strategy is the same as the last one: use your Ultrahand ability and shake it to dislodge every block, or shoot the spot with arrows to eventually stun it. Either way, when all the blocks are scattered, run up to the weak spot and wail on it with your best weapon. Get as much damage in as you can before the Flux Construct II reassembles itself.
The Second Phase
Now, it will likely fly into the air and hover above you in a square-ish shape. You will notice that you can't see the weak point from here, and you can't damage it either. This part is a little tricky to know what to do, as you have to wait for the attack when it sends about five blocks down at you.
When it does this, dodge the blocks, and when they've stopped, run over, jump on one, and then hit it with Recall. This will bring you back up to the Flux Construct II on its back. Here, you can attack the weak spot until the entire thing falls apart again. Be careful, as it can cause damage when it falls apart, so be ready for this.
The Third Phase
The next phase will be its cube form. It assembles itself into a cube and then will roll after you. Pay attention as it rolls, and you will see that one side has a weak spot in the middle of it. When you see it, take out your bow and shoot it with arrows until it is stunned. Then, as usual, go to town on it to do as much damage as you can.
You can also try to use Ultrahand again to grab onto the weak point and shake it out of the cube. This method is just much more difficult as the cube continues to turn on its sides and moves faster toward you. Ultrahand slows you down, so you are opening yourself up to getting hit a lot more with this strategy. Also, look out for its attack during the cube phase, where it goes into the air, moves over you, and then comes smashing down on you. Just sprint away to avoid this attack, as it can do a good amount of damage.
Eventually, if you follow these strategies, Flux Construct II will fall.
Once it is down, you can collect a good amount of rewards from it:
- Flux Construct II Core (20 Fuse Attack Power)
- Zonai Charge/Large Zonai Charge
The Flux Construct II Cores are the best part of the drops, and are something that can be a huge help when you are Fusing weapons. It can more than double the amount of damage you are doing.
That doesn't mean, however, that the Zonai Charges aren't worth hoarding, as they can offer an easy way to operate the vehicles and contraptions you build in the game. Using a normal Zonai Charge allows you to recharge a single Energy Well, with the Large Zonai Charges allowing you to recharge several Energy Wells.
You can also use them at Device Dispensers around the game to gain a good amount of Zonai Capsules. Given how often you will be constructing various machines throughout the game, a steady supply of Zonai Charges is a must-have for your inventory.
