Taking out a Hinox becomes insanely easy with the Biggoron Sword (base attack of 36) fused with a good material and it’s very easy to acquire. In the middle of Skull Lake in Akkala, there’s a chasm that takes you to the House of Bones. After you take down the Stalnox and other skeletons, the chest opens and gives you the sword. Then you can buy them with Poes from Bargainer Statues 🙂
It should also be useful for taking down the Stone Talus by fusing it with a blunt material, giving you a high-powered hammer
