Blue Moblin Horn
Blue Moblin Horn is a material found in Tears of the Kingdom.
Tears of the Kingdom
"A large, curved horn with two extremely hard tips. Attach it to a weapon to moderately increase its attack power, or cook it with a critter to make an elixir."
Blue Moblin Horns are dropped by Blue Moblins on defeat. They have a fuse attack power of 13, and make blunt weapons when fused. They can be sold to merchants and shops for 9 rupees a piece, or used for brown dye at the Kochi Dye Shop.
They can also be used in cooking elixirs, which increment Link's stats for a period of time. However, they do not contribute anything special or unusual to the result - increasing the effect duration of an elixir by only an average-level 40 seconds per horn.
Fifteen Blue Moblin Horns are required as part of the cost of upgrading the Flamebreaker Set to ★★★ level, five each for a Flamebreaker Helm, a Flamebreaker Armor and pair of Flamebreaker Boots. They are not used in any other armor upgrades.
