Not available until World Level reaches 4266.
Sharp Fused Weapons
Captain Construct IV Horn is a type of material in Tears of the Kingdom.
Tears of the Kingdom
""A mean-looking, branching, blade-like horn. Its edges and tips are extremely sharp. Attach it to a weapon to vastly increase its attack power."
Captain Construct IV Horns are primarily obtained by defeating Captain Construct IVs, although they can occasionally be found in treasure chests as part of "Captain IV" Fused Weapons once the World Level reaches 4266. Their primary use is to fuse to weapons, with a base fuse attack power of 35. to make sharp blades which do not attract lightning. As a Zonai item, they resonate with Zonai weapons, such as Mighty Zonaite Swords, Mighty Zonaite Longswords and Mighty Zonaite Spears to boost their fuse attack power.
They cannot be used to make elixirs, nor are they required for any clothing upgrades or quests. However, they can be used for green dye at the Kochi Dye Shop, sold to shops and merchants for 30 rupees a piece, or traded for Zonai Devices in a Zonai Device Dispenser.
